The runtime has -been completely rewritten in gcc 2.4. The earlier runtime had several -severe bugs and was rather incomplete. The compiler has had several -new features added as well. - -This is not documentation for Objective C, it is usable to someone -who knows Objective C from somewhere else. - - -Runtime API functions -===================== - -The runtime is modeled after the NeXT Objective C runtime. That is, -most functions have semantics as it is known from the NeXT. The -names, however, have changed. All runtime API functions have names -of lowercase letters and underscores as opposed to the -`traditional' mixed case names. - The runtime api functions are not documented as of now. -Someone offered to write it, and did it, but we were not allowed to -use it by his university (Very sad story). We have started writing -the documentation over again. This will be announced in appropriate -places when it becomes available. - - -Protocols -========= - -Protocols are now fully supported. The semantics is exactly as on the -NeXT. There is a flag to specify how protocols should be typechecked -when adopted to classes. The normal typechecker requires that all -methods in a given protocol must be implemented in the class that -adopts it -- it is not enough to inherit them. The flag -`-Wno-protocol' causes it to allow inherited methods, while -`-Wprotocols' is the default which requires them defined. - - -+load -=========== -This method, if defined, is called for each class and category -implementation when the class is loaded into the runtime. This method -is not inherited, and is thus not called for a subclass that doesn't -define it itself. Thus, each +load method is called exactly once by -the runtime. The runtime invocation of this method is thread safe. - - -+initialize -=========== - -This method, if defined, is called before any other instance or class -methods of that particular class. For the GNU runtime, this method is -not inherited, and is thus not called as initializer for a subclass that -doesn't define it itself. Thus, each +initialize method is called exactly -once by the runtime (or never if no methods of that particular class is -never called). It is wise to guard against multiple invocations anyway -to remain portable with the NeXT runtime. The runtime invocation of -this method is thread safe. - - -Passivation/Activation/Typedstreams -=================================== - -This is supported in the style of NeXT TypedStream's. Consult the -headerfile Typedstreams.h for api functions. I (Kresten) have -rewritten it in Objective C, but this implementation is not part of -2.4, it is available from the GNU Objective C prerelease archive. - There is one difference worth noting concerning objects stored with -objc_write_object_reference (aka NXWriteObjectReference). When these -are read back in, their object is not guaranteed to be available until -the `-awake' method is called in the object that requests that object. -To objc_read_object you must pass a pointer to an id, which is valid -after exit from the function calling it (like e.g. an instance -variable). In general, you should not use objects read in until the --awake method is called. - - -Acknowledgements -================ - -The GNU Objective C team: Geoffrey Knauth (manager), -Tom Wood (compiler) and Kresten Krab Thorup - (runtime) would like to thank a some people for -participating in the development of the present GNU Objective C. - -Paul Burchard and Andrew McCallum - has been very helpful debugging the -runtime. Eric Herring has been very helpful -cleaning up after the documentation-copyright disaster and is now -helping with the new documentation. - -Steve Naroff and Richard Stallman - has been very helpful with implementation details -in the compiler. - - -Bug Reports -=========== - -Please read the section `Submitting Bugreports' of the gcc manual -before you submit any bugs.

Objective-C programs should use these structures and -functions for their thread and mutex work if they wish to maintain a -high degree of portability across platforms. - -The backend is composed of a file with the necessary code to map the ObjC -thread and mutex to a platform specific implementation. For example, the -file thr-solaris.c contains the implementation for Solaris. - -If you are compiling libobjc as part of GCC, the thr-objc.c backend is -always used; this backend uses GCC's gthread code. The thread system -is automatically configured when GCC is configured. Important: make -sure you configure GCC using `--enable-threads' if you want threads ! - -If you want to compile libobjc standalone, then you would need to -modify the configure.in and makefiles for it; and you need to pick an -appropriate backend file for the target platform; you make this choice -by assigning the OBJC_THREAD_FILE make variable to the basename of the -backend file. For example, OBJC_THREAD_FILE=thr-posix would indicate -that the generic posix backend file, thr-posix.c, should be compiled -with the ObjC runtime library. If your platform does not support -threads then you should specify the OBJC_THREAD_FILE=thr-single -backend file to compile the ObjC runtime library without thread or -mutex support; note that programs which rely upon the ObjC thread and -mutex functions will compile and link correctly but attempting to -create a thread or mutex will result in an error. - -It is questionable whether it is really necessary to have both a -frontend and backend function for all available functionality. On the -one hand, it provides a clear, consistent differentiation between what -is public and what is private with the downside of having the overhead -of multiple functions calls. For example, the function to have a -thread yield the processor is objc_thread_yield; in the current -implementation this produces a function call set: - -objc_thread_yield() -> __objc_thread_yield() -> system yield function - -This has two extra function calls over calling the platform specific function -explicitly, but the issue is whether only the overhead of a single function -is necessary. - -objc_thread_yield() -> system yield function - -This breaks the public/private dichotomy between the frontend/backend -for the sake of efficiency. It is possible to just use a preprocessor -define so as to eliminate the extra function call: - -#define objc_thread_yield() __objc_thread_yield() - -This has the undesirable effect that if objc_thread_yield is actually -turned into a function based upon future need; then ObjC programs which -access the thread functions would need to be recompiled versus just -being relinked. - -****************************************************************************** -* Threads: - -The thread system attempts to create multiple threads using whatever -operating system or library thread support is available.

This long preamble comment explains why, and the issues - involved. - - - One of the traditional weaknesses of the GNU Objective-C runtime is - that class method invocations are slow. The reason is that when you - write - - array = [NSArray new]; - - this gets basically compiled into the equivalent of - - array = [(objc_get_class ("NSArray")) new]; - - objc_get_class returns the class pointer corresponding to the string - `NSArray'; and because of the lookup, the operation is more - complicated and slow than a simple instance method invocation. - - Most high performance Objective-C code (using the GNU Objc runtime) - I had the opportunity to read (or write) work around this problem by - caching the class pointer: - - Class arrayClass = [NSArray class]; - - ... later on ... - - array = [arrayClass new]; - array = [arrayClass new]; - array = [arrayClass new]; - - In this case, you always perform a class lookup (the first one), but - then all the [arrayClass new] methods run exactly as fast as an - instance method invocation. It helps if you have many class method - invocations to the same class. - - The long-term solution to this problem would be to modify the - compiler to output tables of class pointers corresponding to all the - class method invocations, and to add code to the runtime to update - these tables - that should in the end allow class method invocations - to perform precisely as fast as instance method invocations, because - no class lookup would be involved. I think the Apple Objective-C - runtime uses this technique. Doing this involves synchronized - modifications in the runtime and in the compiler. - - As a first medicine to the problem, I [NP] have redesigned and - rewritten the way the runtime is performing class lookup. This - doesn't give as much speed as the other (definitive) approach, but - at least a class method invocation now takes approximately 4.5 times - an instance method invocation on my machine (it would take approx 12 - times before the rewriting), which is a lot better. - - One of the main reason the new class lookup is so faster is because - I implemented it in a way that can safely run multithreaded without - using locks - a so-called `lock-free' data structure. The atomic - operation is pointer assignment. The reason why in this problem - lock-free data structures work so well is that you never remove - classes from the table - and the difficult thing with lock-free data - structures is freeing data when is removed from the structures. */ - -#include "objc/runtime.h" /* the kitchen sink */ -#include "objc/sarray.h" - -#include "objc/objc.h" -#include "objc/objc-api.h" -#include "objc/thr.h" - -/* We use a table which maps a class name to the corresponding class - * pointer.

The runtime has -been completely rewritten in gcc 2.4. The earlier runtime had several -severe bugs and was rather incomplete. The compiler has had several -new features added as well. - -This is not documentation for Objective C, it is usable to someone -who knows Objective C from somewhere else. - - -Runtime API functions -===================== - -The runtime is modeled after the NeXT Objective C runtime. That is, -most functions have semantics as it is known from the NeXT. The -names, however, have changed. All runtime API functions have names -of lowercase letters and underscores as opposed to the -`traditional' mixed case names. - The runtime api functions are not documented as of now. -Someone offered to write it, and did it, but we were not allowed to -use it by his university (Very sad story). We have started writing -the documentation over again. This will be announced in appropriate -places when it becomes available. - - -Protocols -========= - -Protocols are now fully supported. The semantics is exactly as on the -NeXT. There is a flag to specify how protocols should be typechecked -when adopted to classes. The normal typechecker requires that all -methods in a given protocol must be implemented in the class that -adopts it -- it is not enough to inherit them. The flag -`-Wno-protocol' causes it to allow inherited methods, while -`-Wprotocols' is the default which requires them defined. - - -+initialize -=========== - -This method, if defined, is called before any other instance or class -methods of that particular class. This method is not inherited, and -is thus not called as initializer for a subclass that doesn't define -it itself. Thus, each +initialize method is called exactly once (or -never if no methods of that particular class is never called). -Besides this, it is allowed to have several +initialize methods, one -for each category. The order in which these (multiple methods) are -called is not well defined. I am not completely certain what the -semantics of this method is for other implementations, but this is -how it works for GNU Objective C. - - -Passivation/Activation/Typedstreams -=================================== - -This is supported in the style of NeXT TypedStream's. Consult the -headerfile Typedstreams.h for api functions. I (Kresten) have -rewritten it in Objective C, but this implementation is not part of -2.4, it is available from the GNU Objective C prerelease archive. - There is one difference worth noting concerning objects stored with -objc_write_object_reference (aka NXWriteObjectReference). When these -are read back in, their object is not guaranteed to be available until -the `-awake' method is called in the object that requests that object. -To objc_read_object you must pass a pointer to an id, which is valid -after exit from the function calling it (like e.g. an instance -variable). In general, you should not use objects read in until the --awake method is called. - - -Acknowledgements -================ - -The GNU Objective C team: Geoffrey Knauth (manager), -Tom Wood (compiler) and Kresten Krab Thorup - (runtime) would like to thank a some people for -participating in the development of the present GNU Objective C. - -Paul Burchard and Andrew McCallum - has been very helpful debugging the -runtime. Eric Herring has been very helpful -cleaning up after the documentation-copyright disaster and is now -helping with the new documentation. - -Steve Naroff and Richard Stallman - has been very helpful with implementation details -in the compiler. - - -Bug Reports -=========== - -Please read the section `Submitting Bugreports' of the gcc manual -before you submit any bugs.

The new library has a new name, -@file{libobjc_gc.a} to not conflict with the non-garbage-collected -library. - -When the garbage collector is used, the objects are allocated using the -so-called typed memory allocation mechanism available in the -Boehm-Demers-Weiser collector. This mode requires precise information on -where pointers are located inside objects. This information is computed -once per class, immediately after the class has been initialized. - -There is a new runtime function @code{class_ivar_set_gcinvisible()} -which can be used to declare a so-called @dfn{weak pointer} -reference. Such a pointer is basically hidden for the garbage collector; -this can be useful in certain situations, especially when you want to -keep track of the allocated objects, yet allow them to be -collected. This kind of pointers can only be members of objects, you -cannot declare a global pointer as a weak reference. Every type which is -a pointer type can be declared a weak pointer, including @code{id}, -@code{Class} and @code{SEL}. - -Here is an example of how to use this feature. Suppose you want to -implement a class whose instances hold a weak pointer reference; the -following class does this: - -@smallexample - -@@interface WeakPointer : Object -@{ - const void* weakPointer; -@} - -- initWithPointer:(const void*)p; -- (const void*)weakPointer; -@@end - - -@@implementation WeakPointer - -+ (void)initialize -@{ - class_ivar_set_gcinvisible (self, "weakPointer", YES); -@} - -- initWithPointer:(const void*)p -@{ - weakPointer = p; - return self; -@} - -- (const void*)weakPointer -@{ - return weakPointer; -@} - -@@end - -@end smallexample - -Weak pointers are supported through a new type character specifier -represented by the @samp{!} character. The -@code{class_ivar_set_gcinvisible()} function adds or removes this -specifier to the string type description of the instance variable named -as argument. - -@c ========================================================================= -@node Constant string objects -@section Constant string objects - -GNU Objective-C provides constant string objects that are generated -directly by the compiler. You declare a constant string object by -prefixing a C constant string with the character @samp{@@}: - -@smallexample - id myString = @@"this is a constant string object"; -@end smallexample - -The constant string objects are by default instances of the -@code{NXConstantString} class which is provided by the GNU Objective-C -runtime. To get the definition of this class you must include the -@file{objc/NXConstStr.h} header file. - -User defined libraries may want to implement their own constant string -class. To be able to support them, the GNU Objective-C compiler provides -a new command line options @option{-fconstant-string-class=@var{class-name}}. -The provided class should adhere to a strict structure, the same -as @code{NXConstantString}'s structure: - -@smallexample - -@@interface MyConstantStringClass -@{ - Class isa; - char *c_string; - unsigned int len; -@} -@@end - -@end smallexample - -@code{NXConstantString} inherits from @code{Object}; user class -libraries may choose to inherit the customized constant string class -from a different class than @code{Object}. There is no requirement in -the methods the constant string class has to implement, but the final -ivar layout of the class must be the compatible with the given -structure. - -When the compiler creates the statically allocated constant string -object, the @code{c_string} field will be filled by the compiler with -the string; the @code{length} field will be filled by the compiler with -the string length; the @code{isa} pointer will be filled with -@code{NULL} by the compiler, and it will later be fixed up automatically -at runtime by the GNU Objective-C runtime library to point to the class -which was set by the @option{-fconstant-string-class} option when the -object file is loaded (if you wonder how it works behind the scenes, the -name of the class to use, and the list of static objects to fixup, are -stored by the compiler in the object file in a place where the GNU -runtime library will find them at runtime). - -As a result, when a file is compiled with the -@option{-fconstant-string-class} option, all the constant string objects -will be instances of the class specified as argument to this option.

It is called a macro processor because it allows you to define \fImacros\fR, which are brief abbreviations for longer constructs. .PP -The C preprocessor is intended to be used only with C, \*(C+, and -Objective-C source code. In the past, it has been abused as a general -text processor. It will choke on input which does not obey C's lexical -rules. For example, apostrophes will be interpreted as the beginning of -character constants, and cause errors. Also, you cannot rely on it -preserving characteristics of the input which are not significant to -C\-family languages. If a Makefile is preprocessed, all the hard tabs -will be removed, and the Makefile will not work. +The C preprocessor is intended to be used only with C and \*(C+ source +code. In the past, it has been abused as a general text processor. It +will choke on input which does not obey C's lexical rules. For +example, apostrophes will be interpreted as the beginning of character +constants, and cause errors. Also, you cannot rely on it preserving +characteristics of the input which are not significant to C\-family +languages. If a Makefile is preprocessed, all the hard tabs will be +removed, and the Makefile will not work. .PP Having said that, you can often get away with using cpp on things which are not C. Other Algol-ish programming languages are often safe (Pascal, Ada, etc.) So is assembly, with caution. \fB\-traditional\-cpp\fR mode preserves more white space, and is otherwise more permissive. Many of the problems can be avoided by writing C or \*(C+ style comments instead of native language comments, and keeping macros simple. .PP Wherever possible, you should use a preprocessor geared to the language you are writing in. Modern versions of the \s-1GNU\s0 assembler have macro facilities. Most high level programming languages have their own conditional compilation and inclusion mechanism. If all else fails, try a true general text processor, such as \s-1GNU\s0 M4. .PP C preprocessors vary in some details. This manual discusses the \s-1GNU\s0 C preprocessor, which provides a small superset of the features of \s-1ISO\s0 Standard C. In its default mode, the \s-1GNU\s0 C preprocessor does not do a few things required by the standard. These are features which are rarely, if ever, used, and may cause surprising changes to the meaning of a program which does not expect them. To get strict \s-1ISO\s0 Standard C, you should use the \fB\-std=c89\fR or \fB\-std=c99\fR options, depending on which version of the standard you want. To get all the mandatory diagnostics, you must also use \fB\-pedantic\fR. .PP This manual describes the behavior of the \s-1ISO\s0 preprocessor. To minimize gratuitous differences, where the \s-1ISO\s0 preprocessor's behavior does not conflict with traditional semantics, the traditional preprocessor should behave the same way. The various differences that do exist are detailed in the section \fBTraditional Mode\fR. .PP For clarity, unless noted otherwise, references to \fB\s-1CPP\s0\fR in this manual refer to \s-1GNU\s0 \s-1CPP\s0. .SH "OPTIONS" .IX Header "OPTIONS" The C preprocessor expects two file names as arguments, \fIinfile\fR and \&\fIoutfile\fR. The preprocessor reads \fIinfile\fR together with any other files it specifies with \fB#include\fR. All the output generated by the combined input files is written in \fIoutfile\fR. .PP Either \fIinfile\fR or \fIoutfile\fR may be \fB\-\fR, which as \&\fIinfile\fR means to read from standard input and as \fIoutfile\fR means to write to standard output. Also, if either file is omitted, it means the same as if \fB\-\fR had been specified for that file. .PP Unless otherwise noted, or the option ends in \fB=\fR, all options which take an argument may have that argument appear either immediately after the option, or with a space between option and argument: \&\fB\-Ifoo\fR and \fB\-I foo\fR have the same effect. .PP Many options have multi-letter names; therefore multiple single-letter options may \fInot\fR be grouped: \fB\-dM\fR is very different from \&\fB\-d\ \-M\fR. .IP "\fB\-D\fR \fIname\fR" 4 .IX Item "-D name" Predefine \fIname\fR as a macro, with definition \f(CW1\fR. .IP "\fB\-D\fR \fIname\fR\fB=\fR\fIdefinition\fR" 4 .IX Item "-D name=definition" The contents of \fIdefinition\fR are tokenized and processed as if they appeared during translation phase three in a \fB#define\fR directive. In particular, the definition will be truncated by embedded newline characters. .Sp If you are invoking the preprocessor from a shell or shell-like program you may need to use the shell's quoting syntax to protect characters such as spaces that have a meaning in the shell syntax. .Sp If you wish to define a function-like macro on the command line, write its argument list with surrounding parentheses before the equals sign (if any). Parentheses are meaningful to most shells, so you will need to quote the option. With \fBsh\fR and \fBcsh\fR, \&\fB\-D'\fR\fIname\fR\fB(\fR\fIargs...\fR\fB)=\fR\fIdefinition\fR\fB'\fR works. .Sp \&\fB\-D\fR and \fB\-U\fR options are processed in the order they are given on the command line. All \fB\-imacros\fR \fIfile\fR and \&\fB\-include\fR \fIfile\fR options are processed after all \&\fB\-D\fR and \fB\-U\fR options. .IP "\fB\-U\fR \fIname\fR" 4 .IX Item "-U name" Cancel any previous definition of \fIname\fR, either built in or provided with a \fB\-D\fR option. .IP "\fB\-undef\fR" 4 .IX Item "-undef" Do not predefine any system-specific or GCC-specific macros. The standard predefined macros remain defined. .IP "\fB\-I\fR \fIdir\fR" 4 .IX Item "-I dir" Add the directory \fIdir\fR to the list of directories to be searched for header files. .Sp Directories named by \fB\-I\fR are searched before the standard system include directories. If the directory \fIdir\fR is a standard system include directory, the option is ignored to ensure that the default search order for system directories and the special treatment of system headers are not defeated \&. .IP "\fB\-o\fR \fIfile\fR" 4 .IX Item "-o file" Write output to \fIfile\fR. This is the same as specifying \fIfile\fR as the second non-option argument to \fBcpp\fR. \fBgcc\fR has a different interpretation of a second non-option argument, so you must use \fB\-o\fR to specify the output file. .IP "\fB\-Wall\fR" 4 .IX Item "-Wall" Turns on all optional warnings which are desirable for normal code. At present this is \fB\-Wcomment\fR, \fB\-Wtrigraphs\fR, \&\fB\-Wmultichar\fR and a warning about integer promotion causing a change of sign in \f(CW\*(C`#if\*(C'\fR expressions. Note that many of the preprocessor's warnings are on by default and have no options to control them. .IP "\fB\-Wcomment\fR" 4 .IX Item "-Wcomment" .PD 0 .IP "\fB\-Wcomments\fR" 4 .IX Item "-Wcomments" .PD Warn whenever a comment-start sequence \fB/*\fR appears in a \fB/*\fR comment, or whenever a backslash-newline appears in a \fB//\fR comment. (Both forms have the same effect.) .IP "\fB\-Wtrigraphs\fR" 4 .IX Item "-Wtrigraphs" Most trigraphs in comments cannot affect the meaning of the program. However, a trigraph that would form an escaped newline (\fB??/\fR at the end of a line) can, by changing where the comment begins or ends. Therefore, only trigraphs that would form escaped newlines produce warnings inside a comment. .Sp This option is implied by \fB\-Wall\fR. If \fB\-Wall\fR is not given, this option is still enabled unless trigraphs are enabled. To get trigraph conversion without warnings, but get the other \&\fB\-Wall\fR warnings, use \fB\-trigraphs \-Wall \-Wno\-trigraphs\fR. .IP "\fB\-Wtraditional\fR" 4 .IX Item "-Wtraditional" Warn about certain constructs that behave differently in traditional and \&\s-1ISO\s0 C. Also warn about \s-1ISO\s0 C constructs that have no traditional C equivalent, and problematic constructs which should be avoided. .IP "\fB\-Wimport\fR" 4 .IX Item "-Wimport" Warn the first time \fB#import\fR is used. .IP "\fB\-Wundef\fR" 4 .IX Item "-Wundef" Warn whenever an identifier which is not a macro is encountered in an \&\fB#if\fR directive, outside of \fBdefined\fR. Such identifiers are replaced with zero. .IP "\fB\-Wunused\-macros\fR" 4 .IX Item "-Wunused-macros" Warn about macros defined in the main file that are unused. A macro is \fIused\fR if it is expanded or tested for existence at least once. The preprocessor will also warn if the macro has not been used at the time it is redefined or undefined. .Sp Built-in macros, macros defined on the command line, and macros defined in include files are not warned about. .Sp \&\fINote:\fR If a macro is actually used, but only used in skipped conditional blocks, then \s-1CPP\s0 will report it as unused. To avoid the warning in such a case, you might improve the scope of the macro's definition by, for example, moving it into the first skipped block. Alternatively, you could provide a dummy use with something like: .Sp .Vb 2 \& #if defined the_macro_causing_the_warning \& #endif .Ve .IP "\fB\-Wendif\-labels\fR" 4 .IX Item "-Wendif-labels" Warn whenever an \fB#else\fR or an \fB#endif\fR are followed by text. This usually happens in code of the form .Sp .Vb 5 \& #if FOO \& ... \& #else FOO \& ... \& #endif FOO .Ve .Sp The second and third \f(CW\*(C`FOO\*(C'\fR should be in comments, but often are not in older programs. This warning is on by default. .IP "\fB\-Werror\fR" 4 .IX Item "-Werror" Make all warnings into hard errors. Source code which triggers warnings will be rejected. .IP "\fB\-Wsystem\-headers\fR" 4 .IX Item "-Wsystem-headers" Issue warnings for code in system headers. These are normally unhelpful in finding bugs in your own code, therefore suppressed. If you are responsible for the system library, you may want to see them. .IP "\fB\-w\fR" 4 .IX Item "-w" Suppress all warnings, including those which \s-1GNU\s0 \s-1CPP\s0 issues by default. .IP "\fB\-pedantic\fR" 4 .IX Item "-pedantic" Issue all the mandatory diagnostics listed in the C standard. Some of them are left out by default, since they trigger frequently on harmless code. .IP "\fB\-pedantic\-errors\fR" 4 .IX Item "-pedantic-errors" Issue all the mandatory diagnostics, and make all mandatory diagnostics into errors. This includes mandatory diagnostics that \s-1GCC\s0 issues without \fB\-pedantic\fR but treats as warnings. .IP "\fB\-M\fR" 4 .IX Item "-M" Instead of outputting the result of preprocessing, output a rule suitable for \fBmake\fR describing the dependencies of the main source file. The preprocessor outputs one \fBmake\fR rule containing the object file name for that source file, a colon, and the names of all the included files, including those coming from \fB\-include\fR or \&\fB\-imacros\fR command line options. .Sp Unless specified explicitly (with \fB\-MT\fR or \fB\-MQ\fR), the object file name consists of the basename of the source file with any suffix replaced with object file suffix. If there are many included files then the rule is split into several lines using \fB\e\fR\-newline. The rule has no commands. .Sp This option does not suppress the preprocessor's debug output, such as \&\fB\-dM\fR. To avoid mixing such debug output with the dependency rules you should explicitly specify the dependency output file with \&\fB\-MF\fR, or use an environment variable like \&\fB\s-1DEPENDENCIES_OUTPUT\s0\fR. Debug output will still be sent to the regular output stream as normal. .Sp Passing \fB\-M\fR to the driver implies \fB\-E\fR, and suppresses warnings with an implicit \fB\-w\fR. .IP "\fB\-MM\fR" 4 .IX Item "-MM" Like \fB\-M\fR but do not mention header files that are found in system header directories, nor header files that are included, directly or indirectly, from such a header. .Sp This implies that the choice of angle brackets or double quotes in an \&\fB#include\fR directive does not in itself determine whether that header will appear in \fB\-MM\fR dependency output. This is a slight change in semantics from \s-1GCC\s0 versions 3.0 and earlier. .IP "\fB\-MF\fR \fIfile\fR" 4 .IX Item "-MF file" When used with \fB\-M\fR or \fB\-MM\fR, specifies a file to write the dependencies to. If no \fB\-MF\fR switch is given the preprocessor sends the rules to the same place it would have sent preprocessed output. .Sp When used with the driver options \fB\-MD\fR or \fB\-MMD\fR, \&\fB\-MF\fR overrides the default dependency output file. .IP "\fB\-MG\fR" 4 .IX Item "-MG" In conjunction with an option such as \fB\-M\fR requesting dependency generation, \fB\-MG\fR assumes missing header files are generated files and adds them to the dependency list without raising an error. The dependency filename is taken directly from the \&\f(CW\*(C`#include\*(C'\fR directive without prepending any path. \fB\-MG\fR also suppresses preprocessed output, as a missing header file renders this useless. .Sp This feature is used in automatic updating of makefiles. .IP "\fB\-MP\fR" 4 .IX Item "-MP" This option instructs \s-1CPP\s0 to add a phony target for each dependency other than the main file, causing each to depend on nothing. These dummy rules work around errors \fBmake\fR gives if you remove header files without updating the \fIMakefile\fR to match. .Sp This is typical output: .Sp .Vb 1 \& test.o: test.c test.h .Ve .Sp .Vb 1 \& test.h: .Ve .IP "\fB\-MT\fR \fItarget\fR" 4 .IX Item "-MT target" Change the target of the rule emitted by dependency generation. By default \s-1CPP\s0 takes the name of the main input file, including any path, deletes any file suffix such as \fB.c\fR, and appends the platform's usual object suffix. The result is the target. .Sp An \fB\-MT\fR option will set the target to be exactly the string you specify. If you want multiple targets, you can specify them as a single argument to \fB\-MT\fR, or use multiple \fB\-MT\fR options. .Sp For example, \fB\-MT\ '$(objpfx)foo.o'\fR might give .Sp .Vb 1 \& $(objpfx)foo.o: foo.c .Ve .IP "\fB\-MQ\fR \fItarget\fR" 4 .IX Item "-MQ target" Same as \fB\-MT\fR, but it quotes any characters which are special to Make. \fB\-MQ\ '$(objpfx)foo.o'\fR gives .Sp .Vb 1 \& $$(objpfx)foo.o: foo.c .Ve .Sp The default target is automatically quoted, as if it were given with \&\fB\-MQ\fR. .IP "\fB\-MD\fR" 4 .IX Item "-MD" \&\fB\-MD\fR is equivalent to \fB\-M \-MF\fR \fIfile\fR, except that \&\fB\-E\fR is not implied. The driver determines \fIfile\fR based on whether an \fB\-o\fR option is given. If it is, the driver uses its argument but with a suffix of \fI.d\fR, otherwise it take the basename of the input file and applies a \fI.d\fR suffix. .Sp If \fB\-MD\fR is used in conjunction with \fB\-E\fR, any \&\fB\-o\fR switch is understood to specify the dependency output file, but if used without \fB\-E\fR, each \fB\-o\fR is understood to specify a target object file. .Sp Since \fB\-E\fR is not implied, \fB\-MD\fR can be used to generate a dependency output file as a side-effect of the compilation process. .IP "\fB\-MMD\fR" 4 .IX Item "-MMD" Like \fB\-MD\fR except mention only user header files, not system header files. .IP "\fB\-x c\fR" 4 .IX Item "-x c" .PD 0 .IP "\fB\-x c++\fR" 4 .IX Item "-x c++" -.IP "\fB\-x objective-c\fR" 4 -.IX Item "-x objective-c" .IP "\fB\-x assembler-with-cpp\fR" 4 .IX Item "-x assembler-with-cpp" .PD -Specify the source language: C, \*(C+, Objective\-C, or assembly.

See the \fB\-\-sysroot\fR option for more information. .IP "\fB\-imultilib\fR \fIdir\fR" 4 .IX Item "-imultilib dir" Use \fIdir\fR as a subdirectory of the directory containing target-specific \*(C+ headers. .IP "\fB\-isystem\fR \fIdir\fR" 4 .IX Item "-isystem dir" Search \fIdir\fR for header files, after all directories specified by \&\fB\-I\fR but before the standard system directories. Mark it as a system directory, so that it gets the same special treatment as is applied to the standard system directories. .IP "\fB\-iquote\fR \fIdir\fR" 4 .IX Item "-iquote dir" Search \fIdir\fR only for header files requested with \&\f(CW\*(C`#include\ "\f(CIfile\f(CW"\*(C'\fR; they are not searched for \&\f(CW\*(C`#include\ <\f(CIfile\f(CW>\*(C'\fR, before all directories specified by \&\fB\-I\fR and before the standard system directories. .IP "\fB\-fdollars\-in\-identifiers\fR" 4 .IX Item "-fdollars-in-identifiers" Accept \fB$\fR in identifiers. .IP "\fB\-fextended\-identifiers\fR" 4 .IX Item "-fextended-identifiers" Accept universal character names in identifiers. This option is experimental; in a future version of \s-1GCC\s0, it will be enabled by default for C99 and \*(C+. .IP "\fB\-fpreprocessed\fR" 4 .IX Item "-fpreprocessed" Indicate to the preprocessor that the input file has already been preprocessed. This suppresses things like macro expansion, trigraph conversion, escaped newline splicing, and processing of most directives. The preprocessor still recognizes and removes comments, so that you can pass a file preprocessed with \fB\-C\fR to the compiler without problems. In this mode the integrated preprocessor is little more than a tokenizer for the front ends. .Sp \&\fB\-fpreprocessed\fR is implicit if the input file has one of the extensions \fB.i\fR, \fB.ii\fR or \fB.mi\fR. These are the extensions that \s-1GCC\s0 uses for preprocessed files created by \&\fB\-save\-temps\fR. .IP "\fB\-ftabstop=\fR\fIwidth\fR" 4 .IX Item "-ftabstop=width" Set the distance between tab stops. This helps the preprocessor report correct column numbers in warnings or errors, even if tabs appear on the line. If the value is less than 1 or greater than 100, the option is ignored. The default is 8. .IP "\fB\-fexec\-charset=\fR\fIcharset\fR" 4 .IX Item "-fexec-charset=charset" Set the execution character set, used for string and character constants. The default is \s-1UTF\-8\s0. \fIcharset\fR can be any encoding supported by the system's \f(CW\*(C`iconv\*(C'\fR library routine. .IP "\fB\-fwide\-exec\-charset=\fR\fIcharset\fR" 4 .IX Item "-fwide-exec-charset=charset" Set the wide execution character set, used for wide string and character constants. The default is \s-1UTF\-32\s0 or \s-1UTF\-16\s0, whichever corresponds to the width of \f(CW\*(C`wchar_t\*(C'\fR. As with \&\fB\-fexec\-charset\fR, \fIcharset\fR can be any encoding supported by the system's \f(CW\*(C`iconv\*(C'\fR library routine; however, you will have problems with encodings that do not fit exactly in \f(CW\*(C`wchar_t\*(C'\fR. .IP "\fB\-finput\-charset=\fR\fIcharset\fR" 4 .IX Item "-finput-charset=charset" Set the input character set, used for translation from the character set of the input file to the source character set used by \s-1GCC\s0. If the locale does not specify, or \s-1GCC\s0 cannot get this information from the locale, the default is \s-1UTF\-8\s0. This can be overridden by either the locale or this command line option. Currently the command line option takes precedence if there's a conflict. \fIcharset\fR can be any encoding supported by the system's \f(CW\*(C`iconv\*(C'\fR library routine. .IP "\fB\-fworking\-directory\fR" 4 .IX Item "-fworking-directory" Enable generation of linemarkers in the preprocessor output that will let the compiler know the current working directory at the time of preprocessing. When this option is enabled, the preprocessor will emit, after the initial linemarker, a second linemarker with the current working directory followed by two slashes. \s-1GCC\s0 will use this directory, when it's present in the preprocessed input, as the directory emitted as the current working directory in some debugging information formats. This option is implicitly enabled if debugging information is enabled, but this can be inhibited with the negated form \fB\-fno\-working\-directory\fR. If the \fB\-P\fR flag is present in the command line, this option has no effect, since no \&\f(CW\*(C`#line\*(C'\fR directives are emitted whatsoever. .IP "\fB\-fno\-show\-column\fR" 4 .IX Item "-fno-show-column" Do not print column numbers in diagnostics. This may be necessary if diagnostics are being scanned by a program that does not understand the column numbers, such as \fBdejagnu\fR. .IP "\fB\-A\fR \fIpredicate\fR\fB=\fR\fIanswer\fR" 4 .IX Item "-A predicate=answer" Make an assertion with the predicate \fIpredicate\fR and answer \&\fIanswer\fR. This form is preferred to the older form \fB\-A\fR \&\fIpredicate\fR\fB(\fR\fIanswer\fR\fB)\fR, which is still supported, because it does not use shell special characters. .IP "\fB\-A \-\fR\fIpredicate\fR\fB=\fR\fIanswer\fR" 4 .IX Item "-A -predicate=answer" Cancel an assertion with the predicate \fIpredicate\fR and answer \&\fIanswer\fR. .IP "\fB\-dCHARS\fR" 4 .IX Item "-dCHARS" \&\fI\s-1CHARS\s0\fR is a sequence of one or more of the following characters, and must not be preceded by a space. Other characters are interpreted by the compiler proper, or reserved for future versions of \s-1GCC\s0, and so are silently ignored. If you specify characters whose behavior conflicts, the result is undefined. .RS 4 .IP "\fBM\fR" 4 .IX Item "M" Instead of the normal output, generate a list of \fB#define\fR directives for all the macros defined during the execution of the preprocessor, including predefined macros. This gives you a way of finding out what is predefined in your version of the preprocessor. Assuming you have no file \fIfoo.h\fR, the command .Sp .Vb 1 \& touch foo.h; cpp -dM foo.h .Ve .Sp will show all the predefined macros. .IP "\fBD\fR" 4 .IX Item "D" Like \fBM\fR except in two respects: it does \fInot\fR include the predefined macros, and it outputs \fIboth\fR the \fB#define\fR directives and the result of preprocessing. Both kinds of output go to the standard output file. .IP "\fBN\fR" 4 .IX Item "N" Like \fBD\fR, but emit only the macro names, not their expansions. .IP "\fBI\fR" 4 .IX Item "I" Output \fB#include\fR directives in addition to the result of preprocessing. .RE .RS 4 .RE .IP "\fB\-P\fR" 4 .IX Item "-P" Inhibit generation of linemarkers in the output from the preprocessor. This might be useful when running the preprocessor on something that is not C code, and will be sent to a program which might be confused by the linemarkers. .IP "\fB\-C\fR" 4 .IX Item "-C" Do not discard comments. All comments are passed through to the output file, except for comments in processed directives, which are deleted along with the directive. .Sp You should be prepared for side effects when using \fB\-C\fR; it causes the preprocessor to treat comments as tokens in their own right. For example, comments appearing at the start of what would be a directive line have the effect of turning that line into an ordinary source line, since the first token on the line is no longer a \fB#\fR. .IP "\fB\-CC\fR" 4 .IX Item "-CC" Do not discard comments, including during macro expansion. This is like \fB\-C\fR, except that comments contained within macros are also passed through to the output file where the macro is expanded. .Sp In addition to the side-effects of the \fB\-C\fR option, the \&\fB\-CC\fR option causes all \*(C+\-style comments inside a macro to be converted to C\-style comments. This is to prevent later use of that macro from inadvertently commenting out the remainder of the source line. .Sp The \fB\-CC\fR option is generally used to support lint comments. .IP "\fB\-traditional\-cpp\fR" 4 .IX Item "-traditional-cpp" Try to imitate the behavior of old-fashioned C preprocessors, as opposed to \s-1ISO\s0 C preprocessors. .IP "\fB\-trigraphs\fR" 4 .IX Item "-trigraphs" Process trigraph sequences. .IP "\fB\-remap\fR" 4 .IX Item "-remap" Enable special code to work around file systems which only permit very short file names, such as \s-1MS\-DOS\s0. .IP "\fB\-\-help\fR" 4 .IX Item "--help" .PD 0 .IP "\fB\-\-target\-help\fR" 4 .IX Item "--target-help" .PD Print text describing all the command line options instead of preprocessing anything. .IP "\fB\-v\fR" 4 .IX Item "-v" Verbose mode. Print out \s-1GNU\s0 \s-1CPP\s0's version number at the beginning of execution, and report the final form of the include path. .IP "\fB\-H\fR" 4 .IX Item "-H" Print the name of each header file used, in addition to other normal activities. Each name is indented to show how deep in the \&\fB#include\fR stack it is. Precompiled header files are also printed, even if they are found to be invalid; an invalid precompiled header file is printed with \fB...x\fR and a valid one with \fB...!\fR . .IP "\fB\-version\fR" 4 .IX Item "-version" .PD 0 .IP "\fB\-\-version\fR" 4 .IX Item "--version" .PD Print out \s-1GNU\s0 \s-1CPP\s0's version number. With one dash, proceed to preprocess as normal. With two dashes, exit immediately. .SH "ENVIRONMENT" .IX Header "ENVIRONMENT" This section describes the environment variables that affect how \s-1CPP\s0 operates. You can use them to specify directories or prefixes to use when searching for include files, or to control dependency output. .PP Note that you can also specify places to search using options such as \&\fB\-I\fR, and control dependency output with options like \&\fB\-M\fR. These take precedence over environment variables, which in turn take precedence over the configuration of \s-1GCC\s0. .IP "\fB\s-1CPATH\s0\fR" 4 .IX Item "CPATH" .PD 0 .IP "\fBC_INCLUDE_PATH\fR" 4 .IX Item "C_INCLUDE_PATH" .IP "\fB\s-1CPLUS_INCLUDE_PATH\s0\fR" 4 .IX Item "CPLUS_INCLUDE_PATH" -.IP "\fB\s-1OBJC_INCLUDE_PATH\s0\fR" 4 -.IX Item "OBJC_INCLUDE_PATH" .PD Each variable's value is a list of directories separated by a special character, much like \fB\s-1PATH\s0\fR, in which to look for header files. The special character, \f(CW\*(C`PATH_SEPARATOR\*(C'\fR, is target-dependent and determined at \s-1GCC\s0 build time. For Microsoft Windows-based targets it is a semicolon, and for almost all other targets it is a colon. .Sp \&\fB\s-1CPATH\s0\fR specifies a list of directories to be searched as if specified with \fB\-I\fR, but after any paths given with \fB\-I\fR options on the command line. This environment variable is used regardless of which language is being preprocessed. .Sp The remaining environment variables apply only when preprocessing the particular language indicated. Each specifies a list of directories to be searched as if specified with \fB\-isystem\fR, but after any paths given with \fB\-isystem\fR options on the command line. .Sp In all these variables, an empty element instructs the compiler to search its current working directory. Empty elements can appear at the beginning or end of a path. For instance, if the value of \&\fB\s-1CPATH\s0\fR is \f(CW\*(C`:/special/include\*(C'\fR, that has the same effect as \fB\-I.\ \-I/special/include\fR. .IP "\fB\s-1DEPENDENCIES_OUTPUT\s0\fR" 4 .IX Item "DEPENDENCIES_OUTPUT" If this variable is set, its value specifies how to output dependencies for Make based on the non-system header files processed by the compiler. System header files are ignored in the dependency output. .Sp The value of \fB\s-1DEPENDENCIES_OUTPUT\s0\fR can be just a file name, in which case the Make rules are written to that file, guessing the target name from the source file name. Or the value can have the form \&\fIfile\fR\fB \fR\fItarget\fR, in which case the rules are written to file \fIfile\fR using \fItarget\fR as the target name. .Sp In other words, this environment variable is equivalent to combining the options \fB\-MM\fR and \fB\-MF\fR, with an optional \fB\-MT\fR switch too. .IP "\fB\s-1SUNPRO_DEPENDENCIES\s0\fR" 4 .IX Item "SUNPRO_DEPENDENCIES" This variable is the same as \fB\s-1DEPENDENCIES_OUTPUT\s0\fR (see above), except that system header files are not ignored, so it implies \&\fB\-M\fR rather than \fB\-MM\fR. However, the dependence on the main input file is omitted. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fIgpl\fR\|(7), \fIgfdl\fR\|(7), \fIfsf\-funding\fR\|(7), \&\fIgcc\fR\|(1), \fIas\fR\|(1), \fIld\fR\|(1), and the Info entries for \fIcpp\fR, \fIgcc\fR, and \&\fIbinutils\fR. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright (c) 1987, 1989, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005 Free Software Foundation, Inc. .PP Permission is granted to copy, distribute and/or modify this document under the terms of the \s-1GNU\s0 Free Documentation License, Version 1.1 or any later version published by the Free Software Foundation.

It is called a macro processor because it allows you to define @dfn{macros}, which are brief abbreviations for longer constructs. -The C preprocessor is intended to be used only with C, C++, and -Objective-C source code. In the past, it has been abused as a general -text processor. It will choke on input which does not obey C's lexical -rules. For example, apostrophes will be interpreted as the beginning of -character constants, and cause errors. Also, you cannot rely on it -preserving characteristics of the input which are not significant to -C-family languages. If a Makefile is preprocessed, all the hard tabs -will be removed, and the Makefile will not work. +The C preprocessor is intended to be used only with C and C++ source +code.

If a Makefile is preprocessed, all the hard tabs will be +removed, and the Makefile will not work. Having said that, you can often get away with using cpp on things which are not C@. Other Algol-ish programming languages are often safe (Pascal, Ada, etc.) So is assembly, with caution. @option{-traditional-cpp} mode preserves more white space, and is otherwise more permissive. Many of the problems can be avoided by writing C or C++ style comments instead of native language comments, and keeping macros simple. Wherever possible, you should use a preprocessor geared to the language you are writing in. Modern versions of the GNU assembler have macro facilities. Most high level programming languages have their own conditional compilation and inclusion mechanism. If all else fails, try a true general text processor, such as GNU M4. C preprocessors vary in some details. This manual discusses the GNU C preprocessor, which provides a small superset of the features of ISO Standard C@. In its default mode, the GNU C preprocessor does not do a few things required by the standard. These are features which are rarely, if ever, used, and may cause surprising changes to the meaning of a program which does not expect them. To get strict ISO Standard C, you should use the @option{-std=c89} or @option{-std=c99} options, depending on which version of the standard you want. To get all the mandatory diagnostics, you must also use @option{-pedantic}. @xref{Invocation}. This manual describes the behavior of the ISO preprocessor. To minimize gratuitous differences, where the ISO preprocessor's behavior does not conflict with traditional semantics, the traditional preprocessor should behave the same way. The various differences that do exist are detailed in the section @ref{Traditional Mode}. For clarity, unless noted otherwise, references to @samp{CPP} in this manual refer to GNU CPP@. @c man end @menu * Character sets:: * Initial processing:: * Tokenization:: * The preprocessing language:: @end menu @node Character sets @section Character sets Source code character set processing in C and related languages is rather complicated. The C standard discusses two character sets, but there are really at least four. The files input to CPP might be in any character set at all. CPP's very first action, before it even looks for line boundaries, is to convert the file into the character set it uses for internal processing. That set is what the C standard calls the @dfn{source} character set. It must be isomorphic with ISO 10646, also known as Unicode. CPP uses the UTF-8 encoding of Unicode. The character sets of the input files are specified using the @option{-finput-charset=} option. All preprocessing work (the subject of the rest of this manual) is carried out in the source character set. If you request textual output from the preprocessor with the @option{-E} option, it will be in UTF-8. After preprocessing is complete, string and character constants are converted again, into the @dfn{execution} character set. This character set is under control of the user; the default is UTF-8, matching the source character set. Wide string and character constants have their own character set, which is not called out specifically in the standard. Again, it is under control of the user. The default is UTF-16 or UTF-32, whichever fits in the target's @code{wchar_t} type, in the target machine's byte order.@footnote{UTF-16 does not meet the requirements of the C standard for a wide character set, but the choice of 16-bit @code{wchar_t} is enshrined in some system ABIs so we cannot fix this.} Octal and hexadecimal escape sequences do not undergo conversion; @t{'\x12'} has the value 0x12 regardless of the currently selected execution character set. All other escapes are replaced by the character in the source character set that they represent, then converted to the execution character set, just like unescaped characters. Unless the experimental @option{-fextended-identifiers} option is used, GCC does not permit the use of characters outside the ASCII range, nor @samp{\u} and @samp{\U} escapes, in identifiers. Even with that option, characters outside the ASCII range can only be specified with the @samp{\u} and @samp{\U} escapes, not used directly in identifiers. @node Initial processing @section Initial processing The preprocessor performs a series of textual transformations on its input. These happen before all other processing. Conceptually, they happen in a rigid order, and the entire file is run through each transformation before the next one begins. CPP actually does them all at once, for performance reasons. These transformations correspond roughly to the first three ``phases of translation'' described in the C standard. @enumerate @item @cindex line endings The input file is read into memory and broken into lines. Different systems use different conventions to indicate the end of a line. GCC accepts the ASCII control sequences @kbd{LF}, @kbd{@w{CR LF}} and @kbd{CR} as end-of-line markers. These are the canonical sequences used by Unix, DOS and VMS, and the classic Mac OS (before OSX) respectively. You may therefore safely copy source code written on any of those systems to a different one and use it without conversion. (GCC may lose track of the current line number if a file doesn't consistently use one convention, as sometimes happens when it is edited on computers with different conventions that share a network file system.) If the last line of any input file lacks an end-of-line marker, the end of the file is considered to implicitly supply one. The C standard says that this condition provokes undefined behavior, so GCC will emit a warning message. @item @cindex trigraphs @anchor{trigraphs}If trigraphs are enabled, they are replaced by their corresponding single characters. By default GCC ignores trigraphs, but if you request a strictly conforming mode with the @option{-std} option, or you specify the @option{-trigraphs} option, then it converts them. These are nine three-character sequences, all starting with @samp{??}, that are defined by ISO C to stand for single characters. They permit obsolete systems that lack some of C's punctuation to use C@. For example, @samp{??/} stands for @samp{\}, so @t{'??/n'} is a character constant for a newline. Trigraphs are not popular and many compilers implement them incorrectly. Portable code should not rely on trigraphs being either converted or ignored. With @option{-Wtrigraphs} GCC will warn you when a trigraph may change the meaning of your program if it were converted. @xref{Wtrigraphs}. In a string constant, you can prevent a sequence of question marks from being confused with a trigraph by inserting a backslash between the question marks, or by separating the string literal at the trigraph and making use of string literal concatenation. @t{"(??\?)"} is the string @samp{(???)}, not @samp{(?]}. Traditional C compilers do not recognize these idioms. The nine trigraphs and their replacements are @smallexample Trigraph: ??( ??) ??< ??> ??= ??/ ??' ??! ??- Replacement: [ ] @{ @} # \ ^ | ~ @end smallexample @item @cindex continued lines @cindex backslash-newline Continued lines are merged into one long line. A continued line is a line which ends with a backslash, @samp{\}. The backslash is removed and the following line is joined with the current one. No space is inserted, so you may split a line anywhere, even in the middle of a word. (It is generally more readable to split lines only at white space.) The trailing backslash on a continued line is commonly referred to as a @dfn{backslash-newline}. If there is white space between a backslash and the end of a line, that is still a continued line. However, as this is usually the result of an editing mistake, and many compilers will not accept it as a continued line, GCC will warn you about it. @item @cindex comments @cindex line comments @cindex block comments All comments are replaced with single spaces. There are two kinds of comments. @dfn{Block comments} begin with @samp{/*} and continue until the next @samp{*/}. Block comments do not nest: @smallexample /* @r{this is} /* @r{one comment} */ @r{text outside comment} @end smallexample @dfn{Line comments} begin with @samp{//} and continue to the end of the current line. Line comments do not nest either, but it does not matter, because they would end in the same place anyway. @smallexample // @r{this is} // @r{one comment} @r{text outside comment} @end smallexample @end enumerate It is safe to put line comments inside block comments, or vice versa. @smallexample @group /* @r{block comment} // @r{contains line comment} @r{yet more comment} */ @r{outside comment} // @r{line comment} /* @r{contains block comment} */ @end group @end smallexample But beware of commenting out one end of a block comment with a line comment. @smallexample @group // @r{l.c.} /* @r{block comment begins} @r{oops! this isn't a comment anymore} */ @end group @end smallexample Comments are not recognized within string literals. @t{@w{"/* blah */"}} is the string constant @samp{@w{/* blah */}}, not an empty string. Line comments are not in the 1989 edition of the C standard, but they are recognized by GCC as an extension. In C++ and in the 1999 edition of the C standard, they are an official part of the language. Since these transformations happen before all other processing, you can split a line mechanically with backslash-newline anywhere. You can comment out the end of a line. You can continue a line comment onto the next line with backslash-newline. You can even split @samp{/*}, @samp{*/}, and @samp{//} onto multiple lines with backslash-newline. For example: @smallexample @group /\ * */ # /* */ defi\ ne FO\ O 10\ 20 @end group @end smallexample @noindent is equivalent to @code{@w{#define FOO 1020}}. All these tricks are extremely confusing and should not be used in code intended to be readable. There is no way to prevent a backslash at the end of a line from being interpreted as a backslash-newline. This cannot affect any correct program, however. @node Tokenization @section Tokenization @cindex tokens @cindex preprocessing tokens After the textual transformations are finished, the input file is converted into a sequence of @dfn{preprocessing tokens}. These mostly correspond to the syntactic tokens used by the C compiler, but there are a few differences. White space separates tokens; it is not itself a token of any kind. Tokens do not have to be separated by white space, but it is often necessary to avoid ambiguities. When faced with a sequence of characters that has more than one possible tokenization, the preprocessor is greedy. It always makes each token, starting from the left, as big as possible before moving on to the next token. For instance, @code{a+++++b} is interpreted as @code{@w{a ++ ++ + b}}, not as @code{@w{a ++ + ++ b}}, even though the latter tokenization could be part of a valid C program and the former could not. Once the input file is broken into tokens, the token boundaries never change, except when the @samp{##} preprocessing operator is used to paste tokens together. @xref{Concatenation}. For example, @smallexample @group #define foo() bar foo()baz @expansion{} bar baz @emph{not} @expansion{} barbaz @end group @end smallexample The compiler does not re-tokenize the preprocessor's output. Each preprocessing token becomes one compiler token. @cindex identifiers Preprocessing tokens fall into five broad classes: identifiers, preprocessing numbers, string literals, punctuators, and other. An @dfn{identifier} is the same as an identifier in C: any sequence of letters, digits, or underscores, which begins with a letter or underscore. Keywords of C have no significance to the preprocessor; they are ordinary identifiers. You can define a macro whose name is a keyword, for instance. The only identifier which can be considered a preprocessing keyword is @code{defined}. @xref{Defined}. This is mostly true of other languages which use the C preprocessor. However, a few of the keywords of C++ are significant even in the preprocessor. @xref{C++ Named Operators}. In the 1999 C standard, identifiers may contain letters which are not part of the ``basic source character set'', at the implementation's discretion (such as accented Latin letters, Greek letters, or Chinese ideograms). This may be done with an extended character set, or the @samp{\u} and @samp{\U} escape sequences. The implementation of this feature in GCC is experimental; such characters are only accepted in the @samp{\u} and @samp{\U} forms and only if @option{-fextended-identifiers} is used. As an extension, GCC treats @samp{$} as a letter. This is for compatibility with some systems, such as VMS, where @samp{$} is commonly used in system-defined function and object names. @samp{$} is not a letter in strictly conforming mode, or if you specify the @option{-$} option. @xref{Invocation}. @cindex numbers @cindex preprocessing numbers A @dfn{preprocessing number} has a rather bizarre definition. The category includes all the normal integer and floating point constants one expects of C, but also a number of other things one might not initially recognize as a number. Formally, preprocessing numbers begin with an optional period, a required decimal digit, and then continue with any sequence of letters, digits, underscores, periods, and exponents. Exponents are the two-character sequences @samp{e+}, @samp{e-}, @samp{E+}, @samp{E-}, @samp{p+}, @samp{p-}, @samp{P+}, and @samp{P-}. (The exponents that begin with @samp{p} or @samp{P} are new to C99. They are used for hexadecimal floating-point constants.) The purpose of this unusual definition is to isolate the preprocessor from the full complexity of numeric constants. It does not have to distinguish between lexically valid and invalid floating-point numbers, which is complicated. The definition also permits you to split an identifier at any position and get exactly two tokens, which can then be pasted back together with the @samp{##} operator. It's possible for preprocessing numbers to cause programs to be misinterpreted. For example, @code{0xE+12} is a preprocessing number which does not translate to any valid numeric constant, therefore a syntax error. It does not mean @code{@w{0xE + 12}}, which is what you might have intended. @cindex string literals @cindex string constants @cindex character constants @cindex header file names @c the @: prevents makeinfo from turning '' into ". @dfn{String literals} are string constants, character constants, and header file names (the argument of @samp{#include}).@footnote{The C standard uses the term @dfn{string literal} to refer only to what we are calling @dfn{string constants}.} String constants and character constants are straightforward: @t{"@dots{}"} or @t{'@dots{}'}. In either case embedded quotes should be escaped with a backslash: @t{'\'@:'} is the character constant for @samp{'}. There is no limit on the length of a character constant, but the value of a character constant that contains more than one character is implementation-defined. @xref{Implementation Details}. Header file names either look like string constants, @t{"@dots{}"}, or are written with angle brackets instead, @t{<@dots{}>}. In either case, backslash is an ordinary character. There is no way to escape the closing quote or angle bracket. The preprocessor looks for the header file in different places depending on which form you use. @xref{Include Operation}. No string literal may extend past the end of a line. Older versions of GCC accepted multi-line string constants. You may use continued lines instead, or string constant concatenation. @xref{Differences from previous versions}. @cindex punctuators @cindex digraphs @cindex alternative tokens @dfn{Punctuators} are all the usual bits of punctuation which are meaningful to C and C++. All but three of the punctuation characters in ASCII are C punctuators. The exceptions are @samp{@@}, @samp{$}, and @samp{`}. In addition, all the two- and three-character operators are punctuators. There are also six @dfn{digraphs}, which the C++ standard calls @dfn{alternative tokens}, which are merely alternate ways to spell other punctuators. This is a second attempt to work around missing punctuation in obsolete systems. It has no negative side effects, unlike trigraphs, but does not cover as much ground. The digraphs and their corresponding normal punctuators are: @smallexample Digraph: <% %> <: :> %: %:%: Punctuator: @{ @} [ ] # ## @end smallexample @cindex other tokens Any other single character is considered ``other''. It is passed on to the preprocessor's output unmolested. The C compiler will almost certainly reject source code containing ``other'' tokens. In ASCII, the only other characters are @samp{@@}, @samp{$}, @samp{`}, and control characters other than NUL (all bits zero). (Note that @samp{$} is normally considered a letter.) All characters with the high bit set (numeric range 0x7F--0xFF) are also ``other'' in the present implementation. This will change when proper support for international character sets is added to GCC@. NUL is a special case because of the high probability that its appearance is accidental, and because it may be invisible to the user (many terminals do not display NUL at all). Within comments, NULs are silently ignored, just as any other character would be. In running text, NUL is considered white space. For example, these two directives have the same meaning. @smallexample #define X^@@1 #define X 1 @end smallexample @noindent (where @samp{^@@} is ASCII NUL)@. Within string or character constants, NULs are preserved. In the latter two cases the preprocessor emits a warning message. @node The preprocessing language @section The preprocessing language @cindex directives @cindex preprocessing directives @cindex directive line @cindex directive name After tokenization, the stream of tokens may simply be passed straight to the compiler's parser. However, if it contains any operations in the @dfn{preprocessing language}, it will be transformed first. This stage corresponds roughly to the standard's ``translation phase 4'' and is what most people think of as the preprocessor's job. The preprocessing language consists of @dfn{directives} to be executed and @dfn{macros} to be expanded. Its primary capabilities are: @itemize @bullet @item Inclusion of header files. These are files of declarations that can be substituted into your program. @item Macro expansion. You can define @dfn{macros}, which are abbreviations for arbitrary fragments of C code. The preprocessor will replace the macros with their definitions throughout the program. Some macros are automatically defined for you. @item Conditional compilation. You can include or exclude parts of the program according to various conditions. @item Line control. If you use a program to combine or rearrange source files into an intermediate file which is then compiled, you can use line control to inform the compiler where each source line originally came from. @item Diagnostics. You can detect problems at compile time and issue errors or warnings. @end itemize There are a few more, less useful, features. Except for expansion of predefined macros, all these operations are triggered with @dfn{preprocessing directives}. Preprocessing directives are lines in your program that start with @samp{#}. Whitespace is allowed before and after the @samp{#}. The @samp{#} is followed by an identifier, the @dfn{directive name}. It specifies the operation to perform. Directives are commonly referred to as @samp{#@var{name}} where @var{name} is the directive name. For example, @samp{#define} is the directive that defines a macro. The @samp{#} which begins a directive cannot come from a macro expansion. Also, the directive name is not macro expanded. Thus, if @code{foo} is defined as a macro expanding to @code{define}, that does not make @samp{#foo} a valid preprocessing directive. The set of valid directive names is fixed. Programs cannot define new preprocessing directives. Some directives require arguments; these make up the rest of the directive line and must be separated from the directive name by whitespace. For example, @samp{#define} must be followed by a macro name and the intended expansion of the macro. A preprocessing directive cannot cover more than one line. The line may, however, be continued with backslash-newline, or by a block comment which extends past the end of the line. In either case, when the directive is processed, the continuations have already been merged with the first line to make one long line. @node Header Files @chapter Header Files @cindex header file A header file is a file containing C declarations and macro definitions (@pxref{Macros}) to be shared between several source files. You request the use of a header file in your program by @dfn{including} it, with the C preprocessing directive @samp{#include}. Header files serve two purposes. @itemize @bullet @item @cindex system header files System header files declare the interfaces to parts of the operating system. You include them in your program to supply the definitions and declarations you need to invoke system calls and libraries. @item Your own header files contain declarations for interfaces between the source files of your program. Each time you have a group of related declarations and macro definitions all or most of which are needed in several different source files, it is a good idea to create a header file for them. @end itemize Including a header file produces the same results as copying the header file into each source file that needs it. Such copying would be time-consuming and error-prone. With a header file, the related declarations appear in only one place. If they need to be changed, they can be changed in one place, and programs that include the header file will automatically use the new version when next recompiled. The header file eliminates the labor of finding and changing all the copies as well as the risk that a failure to find one copy will result in inconsistencies within a program. In C, the usual convention is to give header files names that end with @file{.h}. It is most portable to use only letters, digits, dashes, and underscores in header file names, and at most one dot. @menu * Include Syntax:: * Include Operation:: * Search Path:: * Once-Only Headers:: * Computed Includes:: * Wrapper Headers:: * System Headers:: @end menu @node Include Syntax @section Include Syntax @findex #include Both user and system header files are included using the preprocessing directive @samp{#include}. It has two variants: @table @code @item #include <@var{file}> This variant is used for system header files. It searches for a file named @var{file} in a standard list of system directories. You can prepend directories to this list with the @option{-I} option (@pxref{Invocation}). @item #include "@var{file}" This variant is used for header files of your own program. It searches for a file named @var{file} first in the directory containing the current file, then in the quote directories and then the same directories used for @code{<@var{file}>}. You can prepend directories to the list of quote directories with the @option{-iquote} option. @end table The argument of @samp{#include}, whether delimited with quote marks or angle brackets, behaves like a string constant in that comments are not recognized, and macro names are not expanded. Thus, @code{@w{#include }} specifies inclusion of a system header file named @file{x/*y}. However, if backslashes occur within @var{file}, they are considered ordinary text characters, not escape characters. None of the character escape sequences appropriate to string constants in C are processed. Thus, @code{@w{#include "x\n\\y"}} specifies a filename containing three backslashes. (Some systems interpret @samp{\} as a pathname separator. All of these also interpret @samp{/} the same way. It is most portable to use only @samp{/}.) It is an error if there is anything (other than comments) on the line after the file name. @node Include Operation @section Include Operation The @samp{#include} directive works by directing the C preprocessor to scan the specified file as input before continuing with the rest of the current file. The output from the preprocessor contains the output already generated, followed by the output resulting from the included file, followed by the output that comes from the text after the @samp{#include} directive. For example, if you have a header file @file{header.h} as follows, @smallexample char *test (void); @end smallexample @noindent and a main program called @file{program.c} that uses the header file, like this, @smallexample int x; #include "header.h" int main (void) @{ puts (test ()); @} @end smallexample @noindent the compiler will see the same token stream as it would if @file{program.c} read @smallexample int x; char *test (void); int main (void) @{ puts (test ()); @} @end smallexample Included files are not limited to declarations and macro definitions; those are merely the typical uses. Any fragment of a C program can be included from another file. The include file could even contain the beginning of a statement that is concluded in the containing file, or the end of a statement that was started in the including file. However, an included file must consist of complete tokens. Comments and string literals which have not been closed by the end of an included file are invalid. For error recovery, they are considered to end at the end of the file. To avoid confusion, it is best if header files contain only complete syntactic units---function declarations or definitions, type declarations, etc. The line following the @samp{#include} directive is always treated as a separate line by the C preprocessor, even if the included file lacks a final newline. @node Search Path @section Search Path GCC looks in several different places for headers. On a normal Unix system, if you do not instruct it otherwise, it will look for headers requested with @code{@w{#include <@var{file}>}} in: @smallexample /usr/local/include @var{libdir}/gcc/@var{target}/@var{version}/include /usr/@var{target}/include /usr/include @end smallexample For C++ programs, it will also look in @file{/usr/include/g++-v3}, first. In the above, @var{target} is the canonical name of the system GCC was configured to compile code for; often but not always the same as the canonical name of the system it runs on. @var{version} is the version of GCC in use. You can add to this list with the @option{-I@var{dir}} command line option. All the directories named by @option{-I} are searched, in left-to-right order, @emph{before} the default directories. The only exception is when @file{dir} is already searched by default. In this case, the option is ignored and the search order for system directories remains unchanged. Duplicate directories are removed from the quote and bracket search chains before the two chains are merged to make the final search chain. Thus, it is possible for a directory to occur twice in the final search chain if it was specified in both the quote and bracket chains. You can prevent GCC from searching any of the default directories with the @option{-nostdinc} option. This is useful when you are compiling an operating system kernel or some other program that does not use the standard C library facilities, or the standard C library itself. @option{-I} options are not ignored as described above when @option{-nostdinc} is in effect. GCC looks for headers requested with @code{@w{#include "@var{file}"}} first in the directory containing the current file, then in the directories as specified by @option{-iquote} options, then in the same places it would have looked for a header requested with angle brackets. For example, if @file{/usr/include/sys/stat.h} contains @code{@w{#include "types.h"}}, GCC looks for @file{types.h} first in @file{/usr/include/sys}, then in its usual search path. @samp{#line} (@pxref{Line Control}) does not change GCC's idea of the directory containing the current file. You may put @option{-I-} at any point in your list of @option{-I} options. This has two effects. First, directories appearing before the @option{-I-} in the list are searched only for headers requested with quote marks. Directories after @option{-I-} are searched for all headers. Second, the directory containing the current file is not searched for anything, unless it happens to be one of the directories named by an @option{-I} switch. @option{-I-} is deprecated, @option{-iquote} should be used instead. @option{-I. -I-} is not the same as no @option{-I} options at all, and does not cause the same behavior for @samp{<>} includes that @samp{""} includes get with no special options. @option{-I.} searches the compiler's current working directory for header files. That may or may not be the same as the directory containing the current file. If you need to look for headers in a directory named @file{-}, write @option{-I./-}. There are several more ways to adjust the header search path. They are generally less useful. @xref{Invocation}. @node Once-Only Headers @section Once-Only Headers @cindex repeated inclusion @cindex including just once @cindex wrapper @code{#ifndef} If a header file happens to be included twice, the compiler will process its contents twice. This is very likely to cause an error, e.g.@: when the compiler sees the same structure definition twice. Even if it does not, it will certainly waste time. The standard way to prevent this is to enclose the entire real contents of the file in a conditional, like this: @smallexample @group /* File foo. */ #ifndef FILE_FOO_SEEN #define FILE_FOO_SEEN @var{the entire file} #endif /* !FILE_FOO_SEEN */ @end group @end smallexample This construct is commonly known as a @dfn{wrapper #ifndef}. When the header is included again, the conditional will be false, because @code{FILE_FOO_SEEN} is defined. The preprocessor will skip over the entire contents of the file, and the compiler will not see it twice. CPP optimizes even further. It remembers when a header file has a wrapper @samp{#ifndef}. If a subsequent @samp{#include} specifies that header, and the macro in the @samp{#ifndef} is still defined, it does not bother to rescan the file at all. You can put comments outside the wrapper. They will not interfere with this optimization. @cindex controlling macro @cindex guard macro The macro @code{FILE_FOO_SEEN} is called the @dfn{controlling macro} or @dfn{guard macro}. In a user header file, the macro name should not begin with @samp{_}. In a system header file, it should begin with @samp{__} to avoid conflicts with user programs. In any kind of header file, the macro name should contain the name of the file and some additional text, to avoid conflicts with other header files. @node Computed Includes @section Computed Includes @cindex computed includes @cindex macros in include Sometimes it is necessary to select one of several different header files to be included into your program. They might specify configuration parameters to be used on different sorts of operating systems, for instance. You could do this with a series of conditionals, @smallexample #if SYSTEM_1 # include "system_1.h" #elif SYSTEM_2 # include "system_2.h" #elif SYSTEM_3 @dots{} #endif @end smallexample That rapidly becomes tedious. Instead, the preprocessor offers the ability to use a macro for the header name. This is called a @dfn{computed include}. Instead of writing a header name as the direct argument of @samp{#include}, you simply put a macro name there instead: @smallexample #define SYSTEM_H "system_1.h" @dots{} #include SYSTEM_H @end smallexample @noindent @code{SYSTEM_H} will be expanded, and the preprocessor will look for @file{system_1.h} as if the @samp{#include} had been written that way originally. @code{SYSTEM_H} could be defined by your Makefile with a @option{-D} option. You must be careful when you define the macro. @samp{#define} saves tokens, not text. The preprocessor has no way of knowing that the macro will be used as the argument of @samp{#include}, so it generates ordinary tokens, not a header name. This is unlikely to cause problems if you use double-quote includes, which are close enough to string constants. If you use angle brackets, however, you may have trouble. The syntax of a computed include is actually a bit more general than the above. If the first non-whitespace character after @samp{#include} is not @samp{"} or @samp{<}, then the entire line is macro-expanded like running text would be. If the line expands to a single string constant, the contents of that string constant are the file to be included. CPP does not re-examine the string for embedded quotes, but neither does it process backslash escapes in the string. Therefore @smallexample #define HEADER "a\"b" #include HEADER @end smallexample @noindent looks for a file named @file{a\"b}. CPP searches for the file according to the rules for double-quoted includes. If the line expands to a token stream beginning with a @samp{<} token and including a @samp{>} token, then the tokens between the @samp{<} and the first @samp{>} are combined to form the filename to be included. Any whitespace between tokens is reduced to a single space; then any space after the initial @samp{<} is retained, but a trailing space before the closing @samp{>} is ignored. CPP searches for the file according to the rules for angle-bracket includes. In either case, if there are any tokens on the line after the file name, an error occurs and the directive is not processed. It is also an error if the result of expansion does not match either of the two expected forms. These rules are implementation-defined behavior according to the C standard. To minimize the risk of different compilers interpreting your computed includes differently, we recommend you use only a single object-like macro which expands to a string constant. This will also minimize confusion for people reading your program. @node Wrapper Headers @section Wrapper Headers @cindex wrapper headers @cindex overriding a header file @findex #include_next Sometimes it is necessary to adjust the contents of a system-provided header file without editing it directly. GCC's @command{fixincludes} operation does this, for example. One way to do that would be to create a new header file with the same name and insert it in the search path before the original header. That works fine as long as you're willing to replace the old header entirely. But what if you want to refer to the old header from the new one? You cannot simply include the old header with @samp{#include}. That will start from the beginning, and find your new header again. If your header is not protected from multiple inclusion (@pxref{Once-Only Headers}), it will recurse infinitely and cause a fatal error. You could include the old header with an absolute pathname: @smallexample #include "/usr/include/old-header.h" @end smallexample @noindent This works, but is not clean; should the system headers ever move, you would have to edit the new headers to match. There is no way to solve this problem within the C standard, but you can use the GNU extension @samp{#include_next}. It means, ``Include the @emph{next} file with this name''. This directive works like @samp{#include} except in searching for the specified file: it starts searching the list of header file directories @emph{after} the directory in which the current file was found. Suppose you specify @option{-I /usr/local/include}, and the list of directories to search also includes @file{/usr/include}; and suppose both directories contain @file{signal.h}. Ordinary @code{@w{#include }} finds the file under @file{/usr/local/include}. If that file contains @code{@w{#include_next }}, it starts searching after that directory, and finds the file in @file{/usr/include}. @samp{#include_next} does not distinguish between @code{<@var{file}>} and @code{"@var{file}"} inclusion, nor does it check that the file you specify has the same name as the current file. It simply looks for the file named, starting with the directory in the search path after the one where the current file was found. The use of @samp{#include_next} can lead to great confusion. We recommend it be used only when there is no other alternative. In particular, it should not be used in the headers belonging to a specific program; it should be used only to make global corrections along the lines of @command{fixincludes}. @node System Headers @section System Headers @cindex system header files The header files declaring interfaces to the operating system and runtime libraries often cannot be written in strictly conforming C@. Therefore, GCC gives code found in @dfn{system headers} special treatment. All warnings, other than those generated by @samp{#warning} (@pxref{Diagnostics}), are suppressed while GCC is processing a system header. Macros defined in a system header are immune to a few warnings wherever they are expanded. This immunity is granted on an ad-hoc basis, when we find that a warning generates lots of false positives because of code in macros defined in system headers. Normally, only the headers found in specific directories are considered system headers. These directories are determined when GCC is compiled. There are, however, two ways to make normal headers into system headers. The @option{-isystem} command line option adds its argument to the list of directories to search for headers, just like @option{-I}. Any headers found in that directory will be considered system headers. All directories named by @option{-isystem} are searched @emph{after} all directories named by @option{-I}, no matter what their order was on the command line. If the same directory is named by both @option{-I} and @option{-isystem}, the @option{-I} option is ignored. GCC provides an informative message when this occurs if @option{-v} is used. @findex #pragma GCC system_header There is also a directive, @code{@w{#pragma GCC system_header}}, which tells GCC to consider the rest of the current include file a system header, no matter where it was found. Code that comes before the @samp{#pragma} in the file will not be affected. @code{@w{#pragma GCC system_header}} has no effect in the primary source file. On very old systems, some of the pre-defined system header directories get even more special treatment. GNU C++ considers code in headers found in those directories to be surrounded by an @code{@w{extern "C"}} block. There is no way to request this behavior with a @samp{#pragma}, or from the command line. @node Macros @chapter Macros A @dfn{macro} is a fragment of code which has been given a name. Whenever the name is used, it is replaced by the contents of the macro. There are two kinds of macros. They differ mostly in what they look like when they are used. @dfn{Object-like} macros resemble data objects when used, @dfn{function-like} macros resemble function calls. You may define any valid identifier as a macro, even if it is a C keyword. The preprocessor does not know anything about keywords. This can be useful if you wish to hide a keyword such as @code{const} from an older compiler that does not understand it. However, the preprocessor operator @code{defined} (@pxref{Defined}) can never be defined as a macro, and C++'s named operators (@pxref{C++ Named Operators}) cannot be macros when you are compiling C++. @menu * Object-like Macros:: * Function-like Macros:: * Macro Arguments:: * Stringification:: * Concatenation:: * Variadic Macros:: * Predefined Macros:: * Undefining and Redefining Macros:: * Directives Within Macro Arguments:: * Macro Pitfalls:: @end menu @node Object-like Macros @section Object-like Macros @cindex object-like macro @cindex symbolic constants @cindex manifest constants An @dfn{object-like macro} is a simple identifier which will be replaced by a code fragment. It is called object-like because it looks like a data object in code that uses it. They are most commonly used to give symbolic names to numeric constants. @findex #define You create macros with the @samp{#define} directive. @samp{#define} is followed by the name of the macro and then the token sequence it should be an abbreviation for, which is variously referred to as the macro's @dfn{body}, @dfn{expansion} or @dfn{replacement list}. For example, @smallexample #define BUFFER_SIZE 1024 @end smallexample @noindent defines a macro named @code{BUFFER_SIZE} as an abbreviation for the token @code{1024}. If somewhere after this @samp{#define} directive there comes a C statement of the form @smallexample foo = (char *) malloc (BUFFER_SIZE); @end smallexample @noindent then the C preprocessor will recognize and @dfn{expand} the macro @code{BUFFER_SIZE}. The C compiler will see the same tokens as it would if you had written @smallexample foo = (char *) malloc (1024); @end smallexample By convention, macro names are written in uppercase. Programs are easier to read when it is possible to tell at a glance which names are macros. The macro's body ends at the end of the @samp{#define} line. You may continue the definition onto multiple lines, if necessary, using backslash-newline. When the macro is expanded, however, it will all come out on one line. For example, @smallexample #define NUMBERS 1, \ 2, \ 3 int x[] = @{ NUMBERS @}; @expansion{} int x[] = @{ 1, 2, 3 @}; @end smallexample @noindent The most common visible consequence of this is surprising line numbers in error messages. There is no restriction on what can go in a macro body provided it decomposes into valid preprocessing tokens. Parentheses need not balance, and the body need not resemble valid C code. (If it does not, you may get error messages from the C compiler when you use the macro.) The C preprocessor scans your program sequentially. Macro definitions take effect at the place you write them. Therefore, the following input to the C preprocessor @smallexample foo = X; #define X 4 bar = X; @end smallexample @noindent produces @smallexample foo = X; bar = 4; @end smallexample When the preprocessor expands a macro name, the macro's expansion replaces the macro invocation, then the expansion is examined for more macros to expand. For example, @smallexample @group #define TABLESIZE BUFSIZE #define BUFSIZE 1024 TABLESIZE @expansion{} BUFSIZE @expansion{} 1024 @end group @end smallexample @noindent @code{TABLESIZE} is expanded first to produce @code{BUFSIZE}, then that macro is expanded to produce the final result, @code{1024}. Notice that @code{BUFSIZE} was not defined when @code{TABLESIZE} was defined. The @samp{#define} for @code{TABLESIZE} uses exactly the expansion you specify---in this case, @code{BUFSIZE}---and does not check to see whether it too contains macro names. Only when you @emph{use} @code{TABLESIZE} is the result of its expansion scanned for more macro names. This makes a difference if you change the definition of @code{BUFSIZE} at some point in the source file. @code{TABLESIZE}, defined as shown, will always expand using the definition of @code{BUFSIZE} that is currently in effect: @smallexample #define BUFSIZE 1020 #define TABLESIZE BUFSIZE #undef BUFSIZE #define BUFSIZE 37 @end smallexample @noindent Now @code{TABLESIZE} expands (in two stages) to @code{37}. If the expansion of a macro contains its own name, either directly or via intermediate macros, it is not expanded again when the expansion is examined for more macros. This prevents infinite recursion. @xref{Self-Referential Macros}, for the precise details. @node Function-like Macros @section Function-like Macros @cindex function-like macros You can also define macros whose use looks like a function call. These are called @dfn{function-like macros}. To define a function-like macro, you use the same @samp{#define} directive, but you put a pair of parentheses immediately after the macro name. For example, @smallexample #define lang_init() c_init() lang_init() @expansion{} c_init() @end smallexample A function-like macro is only expanded if its name appears with a pair of parentheses after it. If you write just the name, it is left alone. This can be useful when you have a function and a macro of the same name, and you wish to use the function sometimes. @smallexample extern void foo(void); #define foo() /* @r{optimized inline version} */ @dots{} foo(); funcptr = foo; @end smallexample Here the call to @code{foo()} will use the macro, but the function pointer will get the address of the real function. If the macro were to be expanded, it would cause a syntax error. If you put spaces between the macro name and the parentheses in the macro definition, that does not define a function-like macro, it defines an object-like macro whose expansion happens to begin with a pair of parentheses. @smallexample #define lang_init () c_init() lang_init() @expansion{} () c_init()() @end smallexample The first two pairs of parentheses in this expansion come from the macro. The third is the pair that was originally after the macro invocation. Since @code{lang_init} is an object-like macro, it does not consume those parentheses. @node Macro Arguments @section Macro Arguments @cindex arguments @cindex macros with arguments @cindex arguments in macro definitions Function-like macros can take @dfn{arguments}, just like true functions. To define a macro that uses arguments, you insert @dfn{parameters} between the pair of parentheses in the macro definition that make the macro function-like. The parameters must be valid C identifiers, separated by commas and optionally whitespace. To invoke a macro that takes arguments, you write the name of the macro followed by a list of @dfn{actual arguments} in parentheses, separated by commas. The invocation of the macro need not be restricted to a single logical line---it can cross as many lines in the source file as you wish. The number of arguments you give must match the number of parameters in the macro definition. When the macro is expanded, each use of a parameter in its body is replaced by the tokens of the corresponding argument. (You need not use all of the parameters in the macro body.) As an example, here is a macro that computes the minimum of two numeric values, as it is defined in many C programs, and some uses. @smallexample #define min(X, Y) ((X) < (Y) ? (X) : (Y)) x = min(a, b); @expansion{} x = ((a) < (b) ? (a) : (b)); y = min(1, 2); @expansion{} y = ((1) < (2) ? (1) : (2)); z = min(a + 28, *p); @expansion{} z = ((a + 28) < (*p) ? (a + 28) : (*p)); @end smallexample @noindent (In this small example you can already see several of the dangers of macro arguments. @xref{Macro Pitfalls}, for detailed explanations.) Leading and trailing whitespace in each argument is dropped, and all whitespace between the tokens of an argument is reduced to a single space. Parentheses within each argument must balance; a comma within such parentheses does not end the argument. However, there is no requirement for square brackets or braces to balance, and they do not prevent a comma from separating arguments. Thus, @smallexample macro (array[x = y, x + 1]) @end smallexample @noindent passes two arguments to @code{macro}: @code{array[x = y} and @code{x + 1]}. If you want to supply @code{array[x = y, x + 1]} as an argument, you can write it as @code{array[(x = y, x + 1)]}, which is equivalent C code. All arguments to a macro are completely macro-expanded before they are substituted into the macro body. After substitution, the complete text is scanned again for macros to expand, including the arguments. This rule may seem strange, but it is carefully designed so you need not worry about whether any function call is actually a macro invocation. You can run into trouble if you try to be too clever, though. @xref{Argument Prescan}, for detailed discussion. For example, @code{min (min (a, b), c)} is first expanded to @smallexample min (((a) < (b) ? (a) : (b)), (c)) @end smallexample @noindent and then to @smallexample @group ((((a) < (b) ? (a) : (b))) < (c) ? (((a) < (b) ? (a) : (b))) : (c)) @end group @end smallexample @noindent (Line breaks shown here for clarity would not actually be generated.) @cindex empty macro arguments You can leave macro arguments empty; this is not an error to the preprocessor (but many macros will then expand to invalid code). You cannot leave out arguments entirely; if a macro takes two arguments, there must be exactly one comma at the top level of its argument list. Here are some silly examples using @code{min}: @smallexample min(, b) @expansion{} (( ) < (b) ? ( ) : (b)) min(a, ) @expansion{} ((a ) < ( ) ? (a ) : ( )) min(,) @expansion{} (( ) < ( ) ? ( ) : ( )) min((,),) @expansion{} (((,)) < ( ) ? ((,)) : ( )) min() @error{} macro "min" requires 2 arguments, but only 1 given min(,,) @error{} macro "min" passed 3 arguments, but takes just 2 @end smallexample Whitespace is not a preprocessing token, so if a macro @code{foo} takes one argument, @code{@w{foo ()}} and @code{@w{foo ( )}} both supply it an empty argument. Previous GNU preprocessor implementations and documentation were incorrect on this point, insisting that a function-like macro that takes a single argument be passed a space if an empty argument was required. Macro parameters appearing inside string literals are not replaced by their corresponding actual arguments. @smallexample #define foo(x) x, "x" foo(bar) @expansion{} bar, "x" @end smallexample @node Stringification @section Stringification @cindex stringification @cindex @samp{#} operator Sometimes you may want to convert a macro argument into a string constant. Parameters are not replaced inside string constants, but you can use the @samp{#} preprocessing operator instead. When a macro parameter is used with a leading @samp{#}, the preprocessor replaces it with the literal text of the actual argument, converted to a string constant. Unlike normal parameter replacement, the argument is not macro-expanded first. This is called @dfn{stringification}. There is no way to combine an argument with surrounding text and stringify it all together. Instead, you can write a series of adjacent string constants and stringified arguments. The preprocessor will replace the stringified arguments with string constants. The C compiler will then combine all the adjacent string constants into one long string. Here is an example of a macro definition that uses stringification: @smallexample @group #define WARN_IF(EXP) \ do @{ if (EXP) \ fprintf (stderr, "Warning: " #EXP "\n"); @} \ while (0) WARN_IF (x == 0); @expansion{} do @{ if (x == 0) fprintf (stderr, "Warning: " "x == 0" "\n"); @} while (0); @end group @end smallexample @noindent The argument for @code{EXP} is substituted once, as-is, into the @code{if} statement, and once, stringified, into the argument to @code{fprintf}. If @code{x} were a macro, it would be expanded in the @code{if} statement, but not in the string. The @code{do} and @code{while (0)} are a kludge to make it possible to write @code{WARN_IF (@var{arg});}, which the resemblance of @code{WARN_IF} to a function would make C programmers want to do; see @ref{Swallowing the Semicolon}. Stringification in C involves more than putting double-quote characters around the fragment. The preprocessor backslash-escapes the quotes surrounding embedded string constants, and all backslashes within string and character constants, in order to get a valid C string constant with the proper contents. Thus, stringifying @code{@w{p = "foo\n";}} results in @t{@w{"p = \"foo\\n\";"}}. However, backslashes that are not inside string or character constants are not duplicated: @samp{\n} by itself stringifies to @t{"\n"}. All leading and trailing whitespace in text being stringified is ignored. Any sequence of whitespace in the middle of the text is converted to a single space in the stringified result. Comments are replaced by whitespace long before stringification happens, so they never appear in stringified text. There is no way to convert a macro argument into a character constant. If you want to stringify the result of expansion of a macro argument, you have to use two levels of macros. @smallexample #define xstr(s) str(s) #define str(s) #s #define foo 4 str (foo) @expansion{} "foo" xstr (foo) @expansion{} xstr (4) @expansion{} str (4) @expansion{} "4" @end smallexample @code{s} is stringified when it is used in @code{str}, so it is not macro-expanded first. But @code{s} is an ordinary argument to @code{xstr}, so it is completely macro-expanded before @code{xstr} itself is expanded (@pxref{Argument Prescan}). Therefore, by the time @code{str} gets to its argument, it has already been macro-expanded. @node Concatenation @section Concatenation @cindex concatenation @cindex token pasting @cindex token concatenation @cindex @samp{##} operator It is often useful to merge two tokens into one while expanding macros. This is called @dfn{token pasting} or @dfn{token concatenation}. The @samp{##} preprocessing operator performs token pasting. When a macro is expanded, the two tokens on either side of each @samp{##} operator are combined into a single token, which then replaces the @samp{##} and the two original tokens in the macro expansion. Usually both will be identifiers, or one will be an identifier and the other a preprocessing number. When pasted, they make a longer identifier. This isn't the only valid case. It is also possible to concatenate two numbers (or a number and a name, such as @code{1.5} and @code{e3}) into a number. Also, multi-character operators such as @code{+=} can be formed by token pasting. However, two tokens that don't together form a valid token cannot be pasted together. For example, you cannot concatenate @code{x} with @code{+} in either order. If you try, the preprocessor issues a warning and emits the two tokens. Whether it puts white space between the tokens is undefined. It is common to find unnecessary uses of @samp{##} in complex macros. If you get this warning, it is likely that you can simply remove the @samp{##}. Both the tokens combined by @samp{##} could come from the macro body, but you could just as well write them as one token in the first place. Token pasting is most useful when one or both of the tokens comes from a macro argument. If either of the tokens next to an @samp{##} is a parameter name, it is replaced by its actual argument before @samp{##} executes. As with stringification, the actual argument is not macro-expanded first. If the argument is empty, that @samp{##} has no effect. Keep in mind that the C preprocessor converts comments to whitespace before macros are even considered. Therefore, you cannot create a comment by concatenating @samp{/} and @samp{*}. You can put as much whitespace between @samp{##} and its operands as you like, including comments, and you can put comments in arguments that will be concatenated. However, it is an error if @samp{##} appears at either end of a macro body. Consider a C program that interprets named commands. There probably needs to be a table of commands, perhaps an array of structures declared as follows: @smallexample @group struct command @{ char *name; void (*function) (void); @}; @end group @group struct command commands[] = @{ @{ "quit", quit_command @}, @{ "help", help_command @}, @dots{} @}; @end group @end smallexample It would be cleaner not to have to give each command name twice, once in the string constant and once in the function name. A macro which takes the name of a command as an argument can make this unnecessary. The string constant can be created with stringification, and the function name by concatenating the argument with @samp{_command}. Here is how it is done: @smallexample #define COMMAND(NAME) @{ #NAME, NAME ## _command @} struct command commands[] = @{ COMMAND (quit), COMMAND (help), @dots{} @}; @end smallexample @node Variadic Macros @section Variadic Macros @cindex variable number of arguments @cindex macros with variable arguments @cindex variadic macros A macro can be declared to accept a variable number of arguments much as a function can. The syntax for defining the macro is similar to that of a function. Here is an example: @smallexample #define eprintf(@dots{}) fprintf (stderr, __VA_ARGS__) @end smallexample This kind of macro is called @dfn{variadic}. When the macro is invoked, all the tokens in its argument list after the last named argument (this macro has none), including any commas, become the @dfn{variable argument}. This sequence of tokens replaces the identifier @code{@w{__VA_ARGS__}} in the macro body wherever it appears. Thus, we have this expansion: @smallexample eprintf ("%s:%d: ", input_file, lineno) @expansion{} fprintf (stderr, "%s:%d: ", input_file, lineno) @end smallexample The variable argument is completely macro-expanded before it is inserted into the macro expansion, just like an ordinary argument. You may use the @samp{#} and @samp{##} operators to stringify the variable argument or to paste its leading or trailing token with another token. (But see below for an important special case for @samp{##}.) If your macro is complicated, you may want a more descriptive name for the variable argument than @code{@w{__VA_ARGS__}}. CPP permits this, as an extension. You may write an argument name immediately before the @samp{@dots{}}; that name is used for the variable argument. The @code{eprintf} macro above could be written @smallexample #define eprintf(args@dots{}) fprintf (stderr, args) @end smallexample @noindent using this extension. You cannot use @code{@w{__VA_ARGS__}} and this extension in the same macro. You can have named arguments as well as variable arguments in a variadic macro. We could define @code{eprintf} like this, instead: @smallexample #define eprintf(format, @dots{}) fprintf (stderr, format, __VA_ARGS__) @end smallexample @noindent This formulation looks more descriptive, but unfortunately it is less flexible: you must now supply at least one argument after the format string. In standard C, you cannot omit the comma separating the named argument from the variable arguments. Furthermore, if you leave the variable argument empty, you will get a syntax error, because there will be an extra comma after the format string. @smallexample eprintf("success!\n", ); @expansion{} fprintf(stderr, "success!\n", ); @end smallexample GNU CPP has a pair of extensions which deal with this problem. First, you are allowed to leave the variable argument out entirely: @smallexample eprintf ("success!\n") @expansion{} fprintf(stderr, "success!\n", ); @end smallexample @noindent Second, the @samp{##} token paste operator has a special meaning when placed between a comma and a variable argument. If you write @smallexample #define eprintf(format, @dots{}) fprintf (stderr, format, ##__VA_ARGS__) @end smallexample @noindent and the variable argument is left out when the @code{eprintf} macro is used, then the comma before the @samp{##} will be deleted. This does @emph{not} happen if you pass an empty argument, nor does it happen if the token preceding @samp{##} is anything other than a comma. @smallexample eprintf ("success!\n") @expansion{} fprintf(stderr, "success!\n"); @end smallexample @noindent The above explanation is ambiguous about the case where the only macro parameter is a variable arguments parameter, as it is meaningless to try to distinguish whether no argument at all is an empty argument or a missing argument. In this case the C99 standard is clear that the comma must remain, however the existing GCC extension used to swallow the comma. So CPP retains the comma when conforming to a specific C standard, and drops it otherwise. C99 mandates that the only place the identifier @code{@w{__VA_ARGS__}} can appear is in the replacement list of a variadic macro. It may not be used as a macro name, macro argument name, or within a different type of macro. It may also be forbidden in open text; the standard is ambiguous. We recommend you avoid using it except for its defined purpose. Variadic macros are a new feature in C99. GNU CPP has supported them for a long time, but only with a named variable argument (@samp{args@dots{}}, not @samp{@dots{}} and @code{@w{__VA_ARGS__}}). If you are concerned with portability to previous versions of GCC, you should use only named variable arguments. On the other hand, if you are concerned with portability to other conforming implementations of C99, you should use only @code{@w{__VA_ARGS__}}. Previous versions of CPP implemented the comma-deletion extension much more generally. We have restricted it in this release to minimize the differences from C99. To get the same effect with both this and previous versions of GCC, the token preceding the special @samp{##} must be a comma, and there must be white space between that comma and whatever comes immediately before it: @smallexample #define eprintf(format, args@dots{}) fprintf (stderr, format , ##args) @end smallexample @noindent @xref{Differences from previous versions}, for the gory details. @node Predefined Macros @section Predefined Macros @cindex predefined macros Several object-like macros are predefined; you use them without supplying their definitions. They fall into three classes: standard, common, and system-specific. In C++, there is a fourth category, the named operators. They act like predefined macros, but you cannot undefine them. @menu * Standard Predefined Macros:: * Common Predefined Macros:: * System-specific Predefined Macros:: * C++ Named Operators:: @end menu @node Standard Predefined Macros @subsection Standard Predefined Macros @cindex standard predefined macros. The standard predefined macros are specified by the relevant language standards, so they are available with all compilers that implement those standards. Older compilers may not provide all of them. Their names all start with double underscores. @table @code @item __FILE__ This macro expands to the name of the current input file, in the form of a C string constant. This is the path by which the preprocessor opened the file, not the short name specified in @samp{#include} or as the input file name argument. For example, @code{"/usr/local/include/myheader.h"} is a possible expansion of this macro. @item __LINE__ This macro expands to the current input line number, in the form of a decimal integer constant. While we call it a predefined macro, it's a pretty strange macro, since its ``definition'' changes with each new line of source code. @end table @code{__FILE__} and @code{__LINE__} are useful in generating an error message to report an inconsistency detected by the program; the message can state the source line at which the inconsistency was detected. For example, @smallexample fprintf (stderr, "Internal error: " "negative string length " "%d at %s, line %d.", length, __FILE__, __LINE__); @end smallexample An @samp{#include} directive changes the expansions of @code{__FILE__} and @code{__LINE__} to correspond to the included file. At the end of that file, when processing resumes on the input file that contained the @samp{#include} directive, the expansions of @code{__FILE__} and @code{__LINE__} revert to the values they had before the @samp{#include} (but @code{__LINE__} is then incremented by one as processing moves to the line after the @samp{#include}). A @samp{#line} directive changes @code{__LINE__}, and may change @code{__FILE__} as well. @xref{Line Control}. C99 introduces @code{__func__}, and GCC has provided @code{__FUNCTION__} for a long time. Both of these are strings containing the name of the current function (there are slight semantic differences; see the GCC manual). Neither of them is a macro; the preprocessor does not know the name of the current function. They tend to be useful in conjunction with @code{__FILE__} and @code{__LINE__}, though. @table @code @item __DATE__ This macro expands to a string constant that describes the date on which the preprocessor is being run. The string constant contains eleven characters and looks like @code{@w{"Feb 12 1996"}}. If the day of the month is less than 10, it is padded with a space on the left. If GCC cannot determine the current date, it will emit a warning message (once per compilation) and @code{__DATE__} will expand to @code{@w{"??? ?? ????"}}. @item __TIME__ This macro expands to a string constant that describes the time at which the preprocessor is being run. The string constant contains eight characters and looks like @code{"23:59:01"}. If GCC cannot determine the current time, it will emit a warning message (once per compilation) and @code{__TIME__} will expand to @code{"??:??:??"}. @item __STDC__ In normal operation, this macro expands to the constant 1, to signify that this compiler conforms to ISO Standard C@. If GNU CPP is used with a compiler other than GCC, this is not necessarily true; however, the preprocessor always conforms to the standard unless the @option{-traditional-cpp} option is used. This macro is not defined if the @option{-traditional-cpp} option is used. On some hosts, the system compiler uses a different convention, where @code{__STDC__} is normally 0, but is 1 if the user specifies strict conformance to the C Standard. CPP follows the host convention when processing system header files, but when processing user files @code{__STDC__} is always 1. This has been reported to cause problems; for instance, some versions of Solaris provide X Windows headers that expect @code{__STDC__} to be either undefined or 1. @xref{Invocation}. @item __STDC_VERSION__ This macro expands to the C Standard's version number, a long integer constant of the form @code{@var{yyyy}@var{mm}L} where @var{yyyy} and @var{mm} are the year and month of the Standard version. This signifies which version of the C Standard the compiler conforms to. Like @code{__STDC__}, this is not necessarily accurate for the entire implementation, unless GNU CPP is being used with GCC@. The value @code{199409L} signifies the 1989 C standard as amended in 1994, which is the current default; the value @code{199901L} signifies the 1999 revision of the C standard. Support for the 1999 revision is not yet complete. This macro is not defined if the @option{-traditional-cpp} option is -used, nor when compiling C++ or Objective-C@. +used, nor when compiling C++. @item __STDC_HOSTED__ This macro is defined, with value 1, if the compiler's target is a @dfn{hosted environment}. A hosted environment has the complete facilities of the standard C library available. @item __cplusplus This macro is defined when the C++ compiler is in use. You can use @code{__cplusplus} to test whether a header is compiled by a C compiler or a C++ compiler. This macro is similar to @code{__STDC_VERSION__}, in that it expands to a version number. A fully conforming implementation of the 1998 C++ standard will define this macro to @code{199711L}. The GNU C++ compiler is not yet fully conforming, so it uses @code{1} instead. It is hoped to complete the implementation of standard C++ in the near future. -@item __OBJC__ -This macro is defined, with value 1, when the Objective-C compiler is in -use. You can use @code{__OBJC__} to test whether a header is compiled -by a C compiler or a Objective-C compiler. - @item __ASSEMBLER__ This macro is defined with value 1 when preprocessing assembly language. @end table @node Common Predefined Macros @subsection Common Predefined Macros @cindex common predefined macros The common predefined macros are GNU C extensions. They are available with the same meanings regardless of the machine or operating system on which you are using GNU C@. Their names all start with double underscores. @table @code @item __GNUC__ @itemx __GNUC_MINOR__ @itemx __GNUC_PATCHLEVEL__ These macros are defined by all GNU compilers that use the C -preprocessor: C, C++, and Objective-C@. Their values are the major -version, minor version, and patch level of the compiler, as integer -constants. For example, GCC 3.2.1 will define @code{__GNUC__} to 3, +preprocessor: C and C++. Their values are the major version, minor +version, and patch level of the compiler, as integer constants. For +example, GCC 3.2.1 will define @code{__GNUC__} to 3, @code{__GNUC_MINOR__} to 2, and @code{__GNUC_PATCHLEVEL__} to 1. These macros are also defined if you invoke the preprocessor directly. @code{__GNUC_PATCHLEVEL__} is new to GCC 3.0; it is also present in the widely-used development snapshots leading up to 3.0 (which identify themselves as GCC 2.96 or 2.97, depending on which snapshot you have). If all you need to know is whether or not your program is being compiled by GCC, or a non-GCC compiler that claims to accept the GNU C dialects, you can simply test @code{__GNUC__}. If you need to write code which depends on a specific version, you must be more careful. Each time the minor version is increased, the patch level is reset to zero; each time the major version is increased (which happens rarely), the minor version and patch level are reset. If you wish to use the predefined macros directly in the conditional, you will need to write it like this: @smallexample /* @r{Test for GCC > 3.2.0} */ #if __GNUC__ > 3 || \ (__GNUC__ == 3 && (__GNUC_MINOR__ > 2 || \ (__GNUC_MINOR__ == 2 && \ __GNUC_PATCHLEVEL__ > 0)) @end smallexample @noindent Another approach is to use the predefined macros to calculate a single number, then compare that against a threshold: @smallexample #define GCC_VERSION (__GNUC__ * 10000 \ + __GNUC_MINOR__ * 100 \ + __GNUC_PATCHLEVEL__) @dots{} /* @r{Test for GCC > 3.2.0} */ #if GCC_VERSION > 30200 @end smallexample @noindent Many people find this form easier to understand. @item __GNUG__ The GNU C++ compiler defines this. Testing it is equivalent to testing @code{@w{(__GNUC__ && __cplusplus)}}. @item __STRICT_ANSI__ GCC defines this macro if and only if the @option{-ansi} switch, or a @option{-std} switch specifying strict conformance to some version of ISO C, was specified when GCC was invoked. It is defined to @samp{1}. This macro exists primarily to direct GNU libc's header files to restrict their definitions to the minimal set found in the 1989 C standard. @item __BASE_FILE__ This macro expands to the name of the main input file, in the form of a C string constant. This is the source file that was specified on the command line of the preprocessor or C compiler. @item __INCLUDE_LEVEL__ This macro expands to a decimal integer constant that represents the depth of nesting in include files. The value of this macro is incremented on every @samp{#include} directive and decremented at the end of every included file. It starts out at 0, it's value within the base file specified on the command line. @item __ELF__ This macro is defined if the target uses the ELF object format. @item __VERSION__ This macro expands to a string constant which describes the version of the compiler in use. You should not rely on its contents having any particular form, but it can be counted on to contain at least the release number. @item __OPTIMIZE__ @itemx __OPTIMIZE_SIZE__ @itemx __NO_INLINE__ These macros describe the compilation mode. @code{__OPTIMIZE__} is defined in all optimizing compilations. @code{__OPTIMIZE_SIZE__} is defined if the compiler is optimizing for size, not speed. @code{__NO_INLINE__} is defined if no functions will be inlined into their callers (when not optimizing, or when inlining has been specifically disabled by @option{-fno-inline}). These macros cause certain GNU header files to provide optimized definitions, using macros or inline functions, of system library functions. You should not use these macros in any way unless you make sure that programs will execute with the same effect whether or not they are defined. If they are defined, their value is 1. @item __GNUC_GNU_INLINE__ GCC defines this macro if functions declared @code{inline} will be handled in GCC's traditional gnu89 mode. In this mode an @code{extern inline} function will never be compiled as a standalone function, and an @code{inline} function which is neither @code{extern} nor @code{static} will always be compiled as a standalone function. @item __GNUC_STDC_INLINE__ GCC defines this macro if functions declared @code{inline} will be handled according to the ISO C99 standard. In this mode an @code{extern inline} function will always be compiled as a standalone externally visible function, and an @code{inline} function which is neither @code{extern} nor @code{static} will never be compiled as a standalone function. If this macro is defined, GCC supports the @code{gnu_inline} function attribute as a way to always get the gnu89 behaviour. Support for this and @code{__GNUC_GNU_INLINE__} was added in GCC 4.1.3. If neither macro is defined, an older version of GCC is being used: @code{inline} functions will be compiled in gnu89 mode, and the @code{gnu_inline} function attribute will not be recognized. @item __CHAR_UNSIGNED__ GCC defines this macro if and only if the data type @code{char} is unsigned on the target machine. It exists to cause the standard header file @file{limits.h} to work correctly. You should not use this macro yourself; instead, refer to the standard macros defined in @file{limits.h}. @item __WCHAR_UNSIGNED__ Like @code{__CHAR_UNSIGNED__}, this macro is defined if and only if the data type @code{wchar_t} is unsigned and the front-end is in C++ mode. @item __REGISTER_PREFIX__ This macro expands to a single token (not a string constant) which is the prefix applied to CPU register names in assembly language for this target. You can use it to write assembly that is usable in multiple environments. For example, in the @code{m68k-aout} environment it expands to nothing, but in the @code{m68k-coff} environment it expands to a single @samp{%}. @item __USER_LABEL_PREFIX__ This macro expands to a single token which is the prefix applied to user labels (symbols visible to C code) in assembly. For example, in the @code{m68k-aout} environment it expands to an @samp{_}, but in the @code{m68k-coff} environment it expands to nothing. This macro will have the correct definition even if @option{-f(no-)underscores} is in use, but it will not be correct if target-specific options that adjust this prefix are used (e.g.@: the OSF/rose @option{-mno-underscores} option). @item __SIZE_TYPE__ @itemx __PTRDIFF_TYPE__ @itemx __WCHAR_TYPE__ @itemx __WINT_TYPE__ @itemx __INTMAX_TYPE__ @itemx __UINTMAX_TYPE__ These macros are defined to the correct underlying types for the @code{size_t}, @code{ptrdiff_t}, @code{wchar_t}, @code{wint_t}, @code{intmax_t}, and @code{uintmax_t} typedefs, respectively. They exist to make the standard header files @file{stddef.h} and @file{wchar.h} work correctly. You should not use these macros directly; instead, include the appropriate headers and use the typedefs. @item __CHAR_BIT__ Defined to the number of bits used in the representation of the @code{char} data type. It exists to make the standard header given numerical limits work correctly. You should not use this macro directly; instead, include the appropriate headers. @item __SCHAR_MAX__ @itemx __WCHAR_MAX__ @itemx __SHRT_MAX__ @itemx __INT_MAX__ @itemx __LONG_MAX__ @itemx __LONG_LONG_MAX__ @itemx __INTMAX_MAX__ Defined to the maximum value of the @code{signed char}, @code{wchar_t}, @code{signed short}, @code{signed int}, @code{signed long}, @code{signed long long}, and @code{intmax_t} types respectively. They exist to make the standard header given numerical limits work correctly. You should not use these macros directly; instead, include the appropriate headers. @item __DEPRECATED This macro is defined, with value 1, when compiling a C++ source file with warnings about deprecated constructs enabled. These warnings are enabled by default, but can be disabled with @option{-Wno-deprecated}. @item __EXCEPTIONS This macro is defined, with value 1, when compiling a C++ source file with exceptions enabled. If @option{-fno-exceptions} was used when compiling the file, then this macro will not be defined. @item __USING_SJLJ_EXCEPTIONS__ This macro is defined, with value 1, if the compiler uses the old mechanism based on @code{setjmp} and @code{longjmp} for exception handling. @item __GXX_WEAK__ This macro is defined when compiling a C++ source file. It has the value 1 if the compiler will use weak symbols, COMDAT sections, or other similar techniques to collapse symbols with ``vague linkage'' that are defined in multiple translation units. If the compiler will not collapse such symbols, this macro is defined with value 0. In general, user code should not need to make use of this macro; the purpose of this macro is to ease implementation of the C++ runtime library provided with G++. -@item __NEXT_RUNTIME__ -This macro is defined, with value 1, if (and only if) the NeXT runtime -(as in @option{-fnext-runtime}) is in use for Objective-C@. If the GNU -runtime is used, this macro is not defined, so that you can use this -macro to determine which runtime (NeXT or GNU) is being used. - @item __LP64__ @itemx _LP64 These macros are defined, with value 1, if (and only if) the compilation is for a target where @code{long int} and pointer both use 64-bits and @code{int} uses 32-bit. @item __SSP__ This macro is defined, with value 1, when @option{-fstack-protector} is in use. @item __SSP_ALL__ This macro is defined, with value 2, when @option{-fstack-protector-all} is in use. @item __TIMESTAMP__ This macro expands to a string constant that describes the date and time of the last modification of the current source file. The string constant contains abbreviated day of the week, month, day of the month, time in hh:mm:ss form, year and looks like @code{@w{"Sun Sep 16 01:03:52 1973"}}. If the day of the month is less than 10, it is padded with a space on the left. If GCC cannot determine the current date, it will emit a warning message (once per compilation) and @code{__TIMESTAMP__} will expand to @code{@w{"??? ??? ?? ??:??:?? ????"}}. @end table @node System-specific Predefined Macros @subsection System-specific Predefined Macros @cindex system-specific predefined macros @cindex predefined macros, system-specific @cindex reserved namespace The C preprocessor normally predefines several macros that indicate what type of system and machine is in use. They are obviously different on each target supported by GCC@. This manual, being for all systems and machines, cannot tell you what their names are, but you can use @command{cpp -dM} to see them all. @xref{Invocation}. All system-specific predefined macros expand to the constant 1, so you can test them with either @samp{#ifdef} or @samp{#if}. The C standard requires that all system-specific macros be part of the @dfn{reserved namespace}. All names which begin with two underscores, or an underscore and a capital letter, are reserved for the compiler and library to use as they wish. However, historically system-specific macros have had names with no special prefix; for instance, it is common to find @code{unix} defined on Unix systems. For all such macros, GCC provides a parallel macro with two underscores added at the beginning and the end. If @code{unix} is defined, @code{__unix__} will be defined too. There will never be more than two underscores; the parallel of @code{_mips} is @code{__mips__}. When the @option{-ansi} option, or any @option{-std} option that requests strict conformance, is given to the compiler, all the system-specific predefined macros outside the reserved namespace are suppressed. The parallel macros, inside the reserved namespace, remain defined. We are slowly phasing out all predefined macros which are outside the reserved namespace. You should never use them in new programs, and we encourage you to correct older code to use the parallel macros whenever you find it. We don't recommend you use the system-specific macros that are in the reserved namespace, either. It is better in the long run to check specifically for features you need, using a tool such as @command{autoconf}. @node C++ Named Operators @subsection C++ Named Operators @cindex named operators @cindex C++ named operators @cindex iso646.h In C++, there are eleven keywords which are simply alternate spellings of operators normally written with punctuation. These keywords are treated as such even in the preprocessor. They function as operators in @samp{#if}, and they cannot be defined as macros or poisoned. In C, you can request that those keywords take their C++ meaning by including @file{iso646.h}. That header defines each one as a normal object-like macro expanding to the appropriate punctuator. These are the named operators and their corresponding punctuators: @multitable {Named Operator} {Punctuator} @item Named Operator @tab Punctuator @item @code{and} @tab @code{&&} @item @code{and_eq} @tab @code{&=} @item @code{bitand} @tab @code{&} @item @code{bitor} @tab @code{|} @item @code{compl} @tab @code{~} @item @code{not} @tab @code{!} @item @code{not_eq} @tab @code{!=} @item @code{or} @tab @code{||} @item @code{or_eq} @tab @code{|=} @item @code{xor} @tab @code{^} @item @code{xor_eq} @tab @code{^=} @end multitable @node Undefining and Redefining Macros @section Undefining and Redefining Macros @cindex undefining macros @cindex redefining macros @findex #undef If a macro ceases to be useful, it may be @dfn{undefined} with the @samp{#undef} directive. @samp{#undef} takes a single argument, the name of the macro to undefine. You use the bare macro name, even if the macro is function-like. It is an error if anything appears on the line after the macro name. @samp{#undef} has no effect if the name is not a macro. @smallexample #define FOO 4 x = FOO; @expansion{} x = 4; #undef FOO x = FOO; @expansion{} x = FOO; @end smallexample Once a macro has been undefined, that identifier may be @dfn{redefined} as a macro by a subsequent @samp{#define} directive. The new definition need not have any resemblance to the old definition. However, if an identifier which is currently a macro is redefined, then the new definition must be @dfn{effectively the same} as the old one. Two macro definitions are effectively the same if: @itemize @bullet @item Both are the same type of macro (object- or function-like). @item All the tokens of the replacement list are the same. @item If there are any parameters, they are the same. @item Whitespace appears in the same places in both. It need not be exactly the same amount of whitespace, though. Remember that comments count as whitespace. @end itemize @noindent These definitions are effectively the same: @smallexample #define FOUR (2 + 2) #define FOUR (2 + 2) #define FOUR (2 /* @r{two} */ + 2) @end smallexample @noindent but these are not: @smallexample #define FOUR (2 + 2) #define FOUR ( 2+2 ) #define FOUR (2 * 2) #define FOUR(score,and,seven,years,ago) (2 + 2) @end smallexample If a macro is redefined with a definition that is not effectively the same as the old one, the preprocessor issues a warning and changes the macro to use the new definition. If the new definition is effectively the same, the redefinition is silently ignored. This allows, for instance, two different headers to define a common macro. The preprocessor will only complain if the definitions do not match. @node Directives Within Macro Arguments @section Directives Within Macro Arguments @cindex macro arguments and directives Occasionally it is convenient to use preprocessor directives within the arguments of a macro. The C and C++ standards declare that behavior in these cases is undefined. Versions of CPP prior to 3.2 would reject such constructs with an error message. This was the only syntactic difference between normal functions and function-like macros, so it seemed attractive to remove this limitation, and people would often be surprised that they could not use macros in this way. Moreover, sometimes people would use conditional compilation in the argument list to a normal library function like @samp{printf}, only to find that after a library upgrade @samp{printf} had changed to be a function-like macro, and their code would no longer compile. So from version 3.2 we changed CPP to successfully process arbitrary directives within macro arguments in exactly the same way as it would have processed the directive were the function-like macro invocation not present. If, within a macro invocation, that macro is redefined, then the new definition takes effect in time for argument pre-expansion, but the original definition is still used for argument replacement. Here is a pathological example: @smallexample #define f(x) x x f (1 #undef f #define f 2 f) @end smallexample @noindent which expands to @smallexample 1 2 1 2 @end smallexample @noindent with the semantics described above. @node Macro Pitfalls @section Macro Pitfalls @cindex problems with macros @cindex pitfalls of macros In this section we describe some special rules that apply to macros and macro expansion, and point out certain cases in which the rules have counter-intuitive consequences that you must watch out for. @menu * Misnesting:: * Operator Precedence Problems:: * Swallowing the Semicolon:: * Duplication of Side Effects:: * Self-Referential Macros:: * Argument Prescan:: * Newlines in Arguments:: @end menu @node Misnesting @subsection Misnesting When a macro is called with arguments, the arguments are substituted into the macro body and the result is checked, together with the rest of the input file, for more macro calls. It is possible to piece together a macro call coming partially from the macro body and partially from the arguments. For example, @smallexample #define twice(x) (2*(x)) #define call_with_1(x) x(1) call_with_1 (twice) @expansion{} twice(1) @expansion{} (2*(1)) @end smallexample Macro definitions do not have to have balanced parentheses. By writing an unbalanced open parenthesis in a macro body, it is possible to create a macro call that begins inside the macro body but ends outside of it. For example, @smallexample #define strange(file) fprintf (file, "%s %d", @dots{} strange(stderr) p, 35) @expansion{} fprintf (stderr, "%s %d", p, 35) @end smallexample The ability to piece together a macro call can be useful, but the use of unbalanced open parentheses in a macro body is just confusing, and should be avoided. @node Operator Precedence Problems @subsection Operator Precedence Problems @cindex parentheses in macro bodies You may have noticed that in most of the macro definition examples shown above, each occurrence of a macro argument name had parentheses around it. In addition, another pair of parentheses usually surround the entire macro definition. Here is why it is best to write macros that way. Suppose you define a macro as follows, @smallexample #define ceil_div(x, y) (x + y - 1) / y @end smallexample @noindent whose purpose is to divide, rounding up. (One use for this operation is to compute how many @code{int} objects are needed to hold a certain number of @code{char} objects.) Then suppose it is used as follows: @smallexample a = ceil_div (b & c, sizeof (int)); @expansion{} a = (b & c + sizeof (int) - 1) / sizeof (int); @end smallexample @noindent This does not do what is intended. The operator-precedence rules of C make it equivalent to this: @smallexample a = (b & (c + sizeof (int) - 1)) / sizeof (int); @end smallexample @noindent What we want is this: @smallexample a = ((b & c) + sizeof (int) - 1)) / sizeof (int); @end smallexample @noindent Defining the macro as @smallexample #define ceil_div(x, y) ((x) + (y) - 1) / (y) @end smallexample @noindent provides the desired result. Unintended grouping can result in another way. Consider @code{sizeof ceil_div(1, 2)}. That has the appearance of a C expression that would compute the size of the type of @code{ceil_div (1, 2)}, but in fact it means something very different. Here is what it expands to: @smallexample sizeof ((1) + (2) - 1) / (2) @end smallexample @noindent This would take the size of an integer and divide it by two. The precedence rules have put the division outside the @code{sizeof} when it was intended to be inside. Parentheses around the entire macro definition prevent such problems. Here, then, is the recommended way to define @code{ceil_div}: @smallexample #define ceil_div(x, y) (((x) + (y) - 1) / (y)) @end smallexample @node Swallowing the Semicolon @subsection Swallowing the Semicolon @cindex semicolons (after macro calls) Often it is desirable to define a macro that expands into a compound statement. Consider, for example, the following macro, that advances a pointer (the argument @code{p} says where to find it) across whitespace characters: @smallexample #define SKIP_SPACES(p, limit) \ @{ char *lim = (limit); \ while (p < lim) @{ \ if (*p++ != ' ') @{ \ p--; break; @}@}@} @end smallexample @noindent Here backslash-newline is used to split the macro definition, which must be a single logical line, so that it resembles the way such code would be laid out if not part of a macro definition. A call to this macro might be @code{SKIP_SPACES (p, lim)}. Strictly speaking, the call expands to a compound statement, which is a complete statement with no need for a semicolon to end it. However, since it looks like a function call, it minimizes confusion if you can use it like a function call, writing a semicolon afterward, as in @code{SKIP_SPACES (p, lim);} This can cause trouble before @code{else} statements, because the semicolon is actually a null statement. Suppose you write @smallexample if (*p != 0) SKIP_SPACES (p, lim); else @dots{} @end smallexample @noindent The presence of two statements---the compound statement and a null statement---in between the @code{if} condition and the @code{else} makes invalid C code. The definition of the macro @code{SKIP_SPACES} can be altered to solve this problem, using a @code{do @dots{} while} statement. Here is how: @smallexample #define SKIP_SPACES(p, limit) \ do @{ char *lim = (limit); \ while (p < lim) @{ \ if (*p++ != ' ') @{ \ p--; break; @}@}@} \ while (0) @end smallexample Now @code{SKIP_SPACES (p, lim);} expands into @smallexample do @{@dots{}@} while (0); @end smallexample @noindent which is one statement. The loop executes exactly once; most compilers generate no extra code for it. @node Duplication of Side Effects @subsection Duplication of Side Effects @cindex side effects (in macro arguments) @cindex unsafe macros Many C programs define a macro @code{min}, for ``minimum'', like this: @smallexample #define min(X, Y) ((X) < (Y) ? (X) : (Y)) @end smallexample When you use this macro with an argument containing a side effect, as shown here, @smallexample next = min (x + y, foo (z)); @end smallexample @noindent it expands as follows: @smallexample next = ((x + y) < (foo (z)) ? (x + y) : (foo (z))); @end smallexample @noindent where @code{x + y} has been substituted for @code{X} and @code{foo (z)} for @code{Y}. The function @code{foo} is used only once in the statement as it appears in the program, but the expression @code{foo (z)} has been substituted twice into the macro expansion. As a result, @code{foo} might be called two times when the statement is executed. If it has side effects or if it takes a long time to compute, the results might not be what you intended. We say that @code{min} is an @dfn{unsafe} macro. The best solution to this problem is to define @code{min} in a way that computes the value of @code{foo (z)} only once. The C language offers no standard way to do this, but it can be done with GNU extensions as follows: @smallexample #define min(X, Y) \ (@{ typeof (X) x_ = (X); \ typeof (Y) y_ = (Y); \ (x_ < y_) ? x_ : y_; @}) @end smallexample The @samp{(@{ @dots{} @})} notation produces a compound statement that acts as an expression. Its value is the value of its last statement. This permits us to define local variables and assign each argument to one. The local variables have underscores after their names to reduce the risk of conflict with an identifier of wider scope (it is impossible to avoid this entirely). Now each argument is evaluated exactly once. If you do not wish to use GNU C extensions, the only solution is to be careful when @emph{using} the macro @code{min}. For example, you can calculate the value of @code{foo (z)}, save it in a variable, and use that variable in @code{min}: @smallexample @group #define min(X, Y) ((X) < (Y) ? (X) : (Y)) @dots{} @{ int tem = foo (z); next = min (x + y, tem); @} @end group @end smallexample @noindent (where we assume that @code{foo} returns type @code{int}). @node Self-Referential Macros @subsection Self-Referential Macros @cindex self-reference A @dfn{self-referential} macro is one whose name appears in its definition. Recall that all macro definitions are rescanned for more macros to replace. If the self-reference were considered a use of the macro, it would produce an infinitely large expansion. To prevent this, the self-reference is not considered a macro call. It is passed into the preprocessor output unchanged. Consider an example: @smallexample #define foo (4 + foo) @end smallexample @noindent where @code{foo} is also a variable in your program. Following the ordinary rules, each reference to @code{foo} will expand into @code{(4 + foo)}; then this will be rescanned and will expand into @code{(4 + (4 + foo))}; and so on until the computer runs out of memory. The self-reference rule cuts this process short after one step, at @code{(4 + foo)}. Therefore, this macro definition has the possibly useful effect of causing the program to add 4 to the value of @code{foo} wherever @code{foo} is referred to. In most cases, it is a bad idea to take advantage of this feature. A person reading the program who sees that @code{foo} is a variable will not expect that it is a macro as well. The reader will come across the identifier @code{foo} in the program and think its value should be that of the variable @code{foo}, whereas in fact the value is four greater. One common, useful use of self-reference is to create a macro which expands to itself. If you write @smallexample #define EPERM EPERM @end smallexample @noindent then the macro @code{EPERM} expands to @code{EPERM}. Effectively, it is left alone by the preprocessor whenever it's used in running text. You can tell that it's a macro with @samp{#ifdef}. You might do this if you want to define numeric constants with an @code{enum}, but have @samp{#ifdef} be true for each constant. If a macro @code{x} expands to use a macro @code{y}, and the expansion of @code{y} refers to the macro @code{x}, that is an @dfn{indirect self-reference} of @code{x}. @code{x} is not expanded in this case either. Thus, if we have @smallexample #define x (4 + y) #define y (2 * x) @end smallexample @noindent then @code{x} and @code{y} expand as follows: @smallexample @group x @expansion{} (4 + y) @expansion{} (4 + (2 * x)) y @expansion{} (2 * x) @expansion{} (2 * (4 + y)) @end group @end smallexample @noindent Each macro is expanded when it appears in the definition of the other macro, but not when it indirectly appears in its own definition. @node Argument Prescan @subsection Argument Prescan @cindex expansion of arguments @cindex macro argument expansion @cindex prescan of macro arguments Macro arguments are completely macro-expanded before they are substituted into a macro body, unless they are stringified or pasted with other tokens. After substitution, the entire macro body, including the substituted arguments, is scanned again for macros to be expanded. The result is that the arguments are scanned @emph{twice} to expand macro calls in them. Most of the time, this has no effect. If the argument contained any macro calls, they are expanded during the first scan. The result therefore contains no macro calls, so the second scan does not change it. If the argument were substituted as given, with no prescan, the single remaining scan would find the same macro calls and produce the same results. You might expect the double scan to change the results when a self-referential macro is used in an argument of another macro (@pxref{Self-Referential Macros}): the self-referential macro would be expanded once in the first scan, and a second time in the second scan. However, this is not what happens. The self-references that do not expand in the first scan are marked so that they will not expand in the second scan either. You might wonder, ``Why mention the prescan, if it makes no difference? And why not skip it and make the preprocessor faster?'' The answer is that the prescan does make a difference in three special cases: @itemize @bullet @item Nested calls to a macro. We say that @dfn{nested} calls to a macro occur when a macro's argument contains a call to that very macro. For example, if @code{f} is a macro that expects one argument, @code{f (f (1))} is a nested pair of calls to @code{f}. The desired expansion is made by expanding @code{f (1)} and substituting that into the definition of @code{f}. The prescan causes the expected result to happen. Without the prescan, @code{f (1)} itself would be substituted as an argument, and the inner use of @code{f} would appear during the main scan as an indirect self-reference and would not be expanded. @item Macros that call other macros that stringify or concatenate. If an argument is stringified or concatenated, the prescan does not occur. If you @emph{want} to expand a macro, then stringify or concatenate its expansion, you can do that by causing one macro to call another macro that does the stringification or concatenation. For instance, if you have @smallexample #define AFTERX(x) X_ ## x #define XAFTERX(x) AFTERX(x) #define TABLESIZE 1024 #define BUFSIZE TABLESIZE @end smallexample then @code{AFTERX(BUFSIZE)} expands to @code{X_BUFSIZE}, and @code{XAFTERX(BUFSIZE)} expands to @code{X_1024}. (Not to @code{X_TABLESIZE}. Prescan always does a complete expansion.) @item Macros used in arguments, whose expansions contain unshielded commas. This can cause a macro expanded on the second scan to be called with the wrong number of arguments. Here is an example: @smallexample #define foo a,b #define bar(x) lose(x) #define lose(x) (1 + (x)) @end smallexample We would like @code{bar(foo)} to turn into @code{(1 + (foo))}, which would then turn into @code{(1 + (a,b))}. Instead, @code{bar(foo)} expands into @code{lose(a,b)}, and you get an error because @code{lose} requires a single argument. In this case, the problem is easily solved by the same parentheses that ought to be used to prevent misnesting of arithmetic operations: @smallexample #define foo (a,b) @exdent or #define bar(x) lose((x)) @end smallexample The extra pair of parentheses prevents the comma in @code{foo}'s definition from being interpreted as an argument separator. @end itemize @node Newlines in Arguments @subsection Newlines in Arguments @cindex newlines in macro arguments The invocation of a function-like macro can extend over many logical lines. However, in the present implementation, the entire expansion comes out on one line. Thus line numbers emitted by the compiler or debugger refer to the line the invocation started on, which might be different to the line containing the argument causing the problem. Here is an example illustrating this: @smallexample #define ignore_second_arg(a,b,c) a; c ignore_second_arg (foo (), ignored (), syntax error); @end smallexample @noindent The syntax error triggered by the tokens @code{syntax error} results in an error message citing line three---the line of ignore_second_arg--- even though the problematic code comes from line five. We consider this a bug, and intend to fix it in the near future. @node Conditionals @chapter Conditionals @cindex conditionals A @dfn{conditional} is a directive that instructs the preprocessor to select whether or not to include a chunk of code in the final token stream passed to the compiler. Preprocessor conditionals can test arithmetic expressions, or whether a name is defined as a macro, or both simultaneously using the special @code{defined} operator. A conditional in the C preprocessor resembles in some ways an @code{if} statement in C, but it is important to understand the difference between them. The condition in an @code{if} statement is tested during the execution of your program. Its purpose is to allow your program to behave differently from run to run, depending on the data it is operating on. The condition in a preprocessing conditional directive is tested when your program is compiled. Its purpose is to allow different code to be included in the program depending on the situation at the time of compilation. However, the distinction is becoming less clear. Modern compilers often do test @code{if} statements when a program is compiled, if their conditions are known not to vary at run time, and eliminate code which can never be executed. If you can count on your compiler to do this, you may find that your program is more readable if you use @code{if} statements with constant conditions (perhaps determined by macros). Of course, you can only use this to exclude code, not type definitions or other preprocessing directives, and you can only do it if the code remains syntactically valid when it is not to be used. GCC version 3 eliminates this kind of never-executed code even when not optimizing. Older versions did it only when optimizing. @menu * Conditional Uses:: * Conditional Syntax:: * Deleted Code:: @end menu @node Conditional Uses @section Conditional Uses There are three general reasons to use a conditional. @itemize @bullet @item A program may need to use different code depending on the machine or operating system it is to run on. In some cases the code for one operating system may be erroneous on another operating system; for example, it might refer to data types or constants that do not exist on the other system. When this happens, it is not enough to avoid executing the invalid code. Its mere presence will cause the compiler to reject the program. With a preprocessing conditional, the offending code can be effectively excised from the program when it is not valid. @item You may want to be able to compile the same source file into two different programs. One version might make frequent time-consuming consistency checks on its intermediate data, or print the values of those data for debugging, and the other not. @item A conditional whose condition is always false is one way to exclude code from the program but keep it as a sort of comment for future reference. @end itemize Simple programs that do not need system-specific logic or complex debugging hooks generally will not need to use preprocessing conditionals. @node Conditional Syntax @section Conditional Syntax @findex #if A conditional in the C preprocessor begins with a @dfn{conditional directive}: @samp{#if}, @samp{#ifdef} or @samp{#ifndef}. @menu * Ifdef:: * If:: * Defined:: * Else:: * Elif:: @end menu @node Ifdef @subsection Ifdef @findex #ifdef @findex #endif The simplest sort of conditional is @smallexample @group #ifdef @var{MACRO} @var{controlled text} #endif /* @var{MACRO} */ @end group @end smallexample @cindex conditional group This block is called a @dfn{conditional group}. @var{controlled text} will be included in the output of the preprocessor if and only if @var{MACRO} is defined. We say that the conditional @dfn{succeeds} if @var{MACRO} is defined, @dfn{fails} if it is not. The @var{controlled text} inside of a conditional can include preprocessing directives. They are executed only if the conditional succeeds. You can nest conditional groups inside other conditional groups, but they must be completely nested. In other words, @samp{#endif} always matches the nearest @samp{#ifdef} (or @samp{#ifndef}, or @samp{#if}). Also, you cannot start a conditional group in one file and end it in another. Even if a conditional fails, the @var{controlled text} inside it is still run through initial transformations and tokenization. Therefore, it must all be lexically valid C@. Normally the only way this matters is that all comments and string literals inside a failing conditional group must still be properly ended. The comment following the @samp{#endif} is not required, but it is a good practice if there is a lot of @var{controlled text}, because it helps people match the @samp{#endif} to the corresponding @samp{#ifdef}. Older programs sometimes put @var{MACRO} directly after the @samp{#endif} without enclosing it in a comment. This is invalid code according to the C standard. CPP accepts it with a warning. It never affects which @samp{#ifndef} the @samp{#endif} matches. @findex #ifndef Sometimes you wish to use some code if a macro is @emph{not} defined. You can do this by writing @samp{#ifndef} instead of @samp{#ifdef}. One common use of @samp{#ifndef} is to include code only the first time a header file is included. @xref{Once-Only Headers}. Macro definitions can vary between compilations for several reasons. Here are some samples. @itemize @bullet @item Some macros are predefined on each kind of machine (@pxref{System-specific Predefined Macros}). This allows you to provide code specially tuned for a particular machine. @item System header files define more macros, associated with the features they implement. You can test these macros with conditionals to avoid using a system feature on a machine where it is not implemented. @item Macros can be defined or undefined with the @option{-D} and @option{-U} command line options when you compile the program. You can arrange to compile the same source file into two different programs by choosing a macro name to specify which program you want, writing conditionals to test whether or how this macro is defined, and then controlling the state of the macro with command line options, perhaps set in the Makefile. @xref{Invocation}. @item Your program might have a special header file (often called @file{config.h}) that is adjusted when the program is compiled. It can define or not define macros depending on the features of the system and the desired capabilities of the program. The adjustment can be automated by a tool such as @command{autoconf}, or done by hand. @end itemize @node If @subsection If The @samp{#if} directive allows you to test the value of an arithmetic expression, rather than the mere existence of one macro. Its syntax is @smallexample @group #if @var{expression} @var{controlled text} #endif /* @var{expression} */ @end group @end smallexample @var{expression} is a C expression of integer type, subject to stringent restrictions. It may contain @itemize @bullet @item Integer constants. @item Character constants, which are interpreted as they would be in normal code. @item Arithmetic operators for addition, subtraction, multiplication, division, bitwise operations, shifts, comparisons, and logical operations (@code{&&} and @code{||}). The latter two obey the usual short-circuiting rules of standard C@. @item Macros. All macros in the expression are expanded before actual computation of the expression's value begins. @item Uses of the @code{defined} operator, which lets you check whether macros are defined in the middle of an @samp{#if}. @item Identifiers that are not macros, which are all considered to be the number zero. This allows you to write @code{@w{#if MACRO}} instead of @code{@w{#ifdef MACRO}}, if you know that MACRO, when defined, will always have a nonzero value. Function-like macros used without their function call parentheses are also treated as zero. In some contexts this shortcut is undesirable. The @option{-Wundef} option causes GCC to warn whenever it encounters an identifier which is not a macro in an @samp{#if}. @end itemize The preprocessor does not know anything about types in the language. Therefore, @code{sizeof} operators are not recognized in @samp{#if}, and neither are @code{enum} constants. They will be taken as identifiers which are not macros, and replaced by zero. In the case of @code{sizeof}, this is likely to cause the expression to be invalid. The preprocessor calculates the value of @var{expression}. It carries out all calculations in the widest integer type known to the compiler; on most machines supported by GCC this is 64 bits. This is not the same rule as the compiler uses to calculate the value of a constant expression, and may give different results in some cases. If the value comes out to be nonzero, the @samp{#if} succeeds and the @var{controlled text} is included; otherwise it is skipped. @node Defined @subsection Defined @cindex @code{defined} The special operator @code{defined} is used in @samp{#if} and @samp{#elif} expressions to test whether a certain name is defined as a macro. @code{defined @var{name}} and @code{defined (@var{name})} are both expressions whose value is 1 if @var{name} is defined as a macro at the current point in the program, and 0 otherwise. Thus, @code{@w{#if defined MACRO}} is precisely equivalent to @code{@w{#ifdef MACRO}}. @code{defined} is useful when you wish to test more than one macro for existence at once. For example, @smallexample #if defined (__vax__) || defined (__ns16000__) @end smallexample @noindent would succeed if either of the names @code{__vax__} or @code{__ns16000__} is defined as a macro. Conditionals written like this: @smallexample #if defined BUFSIZE && BUFSIZE >= 1024 @end smallexample @noindent can generally be simplified to just @code{@w{#if BUFSIZE >= 1024}}, since if @code{BUFSIZE} is not defined, it will be interpreted as having the value zero. If the @code{defined} operator appears as a result of a macro expansion, the C standard says the behavior is undefined. GNU cpp treats it as a genuine @code{defined} operator and evaluates it normally. It will warn wherever your code uses this feature if you use the command-line option @option{-pedantic}, since other compilers may handle it differently. @node Else @subsection Else @findex #else The @samp{#else} directive can be added to a conditional to provide alternative text to be used if the condition fails. This is what it looks like: @smallexample @group #if @var{expression} @var{text-if-true} #else /* Not @var{expression} */ @var{text-if-false} #endif /* Not @var{expression} */ @end group @end smallexample @noindent If @var{expression} is nonzero, the @var{text-if-true} is included and the @var{text-if-false} is skipped. If @var{expression} is zero, the opposite happens. You can use @samp{#else} with @samp{#ifdef} and @samp{#ifndef}, too. @node Elif @subsection Elif @findex #elif One common case of nested conditionals is used to check for more than two possible alternatives. For example, you might have @smallexample #if X == 1 @dots{} #else /* X != 1 */ #if X == 2 @dots{} #else /* X != 2 */ @dots{} #endif /* X != 2 */ #endif /* X != 1 */ @end smallexample Another conditional directive, @samp{#elif}, allows this to be abbreviated as follows: @smallexample #if X == 1 @dots{} #elif X == 2 @dots{} #else /* X != 2 and X != 1*/ @dots{} #endif /* X != 2 and X != 1*/ @end smallexample @samp{#elif} stands for ``else if''. Like @samp{#else}, it goes in the middle of a conditional group and subdivides it; it does not require a matching @samp{#endif} of its own. Like @samp{#if}, the @samp{#elif} directive includes an expression to be tested. The text following the @samp{#elif} is processed only if the original @samp{#if}-condition failed and the @samp{#elif} condition succeeds. More than one @samp{#elif} can go in the same conditional group. Then the text after each @samp{#elif} is processed only if the @samp{#elif} condition succeeds after the original @samp{#if} and all previous @samp{#elif} directives within it have failed. @samp{#else} is allowed after any number of @samp{#elif} directives, but @samp{#elif} may not follow @samp{#else}. @node Deleted Code @section Deleted Code @cindex commenting out code If you replace or delete a part of the program but want to keep the old code around for future reference, you often cannot simply comment it out. Block comments do not nest, so the first comment inside the old code will end the commenting-out. The probable result is a flood of syntax errors. One way to avoid this problem is to use an always-false conditional instead. For instance, put @code{#if 0} before the deleted code and @code{#endif} after it. This works even if the code being turned off contains conditionals, but they must be entire conditionals (balanced @samp{#if} and @samp{#endif}). Some people use @code{#ifdef notdef} instead. This is risky, because @code{notdef} might be accidentally defined as a macro, and then the conditional would succeed. @code{#if 0} can be counted on to fail. Do not use @code{#if 0} for comments which are not C code. Use a real comment, instead. The interior of @code{#if 0} must consist of complete tokens; in particular, single-quote characters must balance. Comments often contain unbalanced single-quote characters (known in English as apostrophes). These confuse @code{#if 0}. They don't confuse @samp{/*}. @node Diagnostics @chapter Diagnostics @cindex diagnostic @cindex reporting errors @cindex reporting warnings @findex #error The directive @samp{#error} causes the preprocessor to report a fatal error. The tokens forming the rest of the line following @samp{#error} are used as the error message. You would use @samp{#error} inside of a conditional that detects a combination of parameters which you know the program does not properly support. For example, if you know that the program will not run properly on a VAX, you might write @smallexample @group #ifdef __vax__ #error "Won't work on VAXen. See comments at get_last_object." #endif @end group @end smallexample If you have several configuration parameters that must be set up by the installation in a consistent way, you can use conditionals to detect an inconsistency and report it with @samp{#error}. For example, @smallexample #if !defined(UNALIGNED_INT_ASM_OP) && defined(DWARF2_DEBUGGING_INFO) #error "DWARF2_DEBUGGING_INFO requires UNALIGNED_INT_ASM_OP." #endif @end smallexample @findex #warning The directive @samp{#warning} is like @samp{#error}, but causes the preprocessor to issue a warning and continue preprocessing. The tokens following @samp{#warning} are used as the warning message. You might use @samp{#warning} in obsolete header files, with a message directing the user to the header file which should be used instead. Neither @samp{#error} nor @samp{#warning} macro-expands its argument. Internal whitespace sequences are each replaced with a single space. The line must consist of complete tokens. It is wisest to make the argument of these directives be a single string constant; this avoids problems with apostrophes and the like. @node Line Control @chapter Line Control @cindex line control The C preprocessor informs the C compiler of the location in your source code where each token came from. Presently, this is just the file name and line number. All the tokens resulting from macro expansion are reported as having appeared on the line of the source file where the outermost macro was used. We intend to be more accurate in the future. If you write a program which generates source code, such as the @command{bison} parser generator, you may want to adjust the preprocessor's notion of the current file name and line number by hand. Parts of the output from @command{bison} are generated from scratch, other parts come from a standard parser file. The rest are copied verbatim from @command{bison}'s input. You would like compiler error messages and symbolic debuggers to be able to refer to @code{bison}'s input file. @findex #line @command{bison} or any such program can arrange this by writing @samp{#line} directives into the output file. @samp{#line} is a directive that specifies the original line number and source file name for subsequent input in the current preprocessor input file. @samp{#line} has three variants: @table @code @item #line @var{linenum} @var{linenum} is a non-negative decimal integer constant. It specifies the line number which should be reported for the following line of input. Subsequent lines are counted from @var{linenum}. @item #line @var{linenum} @var{filename} @var{linenum} is the same as for the first form, and has the same effect. In addition, @var{filename} is a string constant. The following line and all subsequent lines are reported to come from the file it specifies, until something else happens to change that. @var{filename} is interpreted according to the normal rules for a string constant: backslash escapes are interpreted. This is different from @samp{#include}. Previous versions of CPP did not interpret escapes in @samp{#line}; we have changed it because the standard requires they be interpreted, and most other compilers do. @item #line @var{anything else} @var{anything else} is checked for macro calls, which are expanded. The result should match one of the above two forms. @end table @samp{#line} directives alter the results of the @code{__FILE__} and @code{__LINE__} predefined macros from that point on. @xref{Standard Predefined Macros}. They do not have any effect on @samp{#include}'s idea of the directory containing the current file. This is a change from GCC 2.95. Previously, a file reading @smallexample #line 1 "../src/gram.y" #include "gram.h" @end smallexample would search for @file{gram.h} in @file{../src}, then the @option{-I} chain; the directory containing the physical source file would not be searched. In GCC 3.0 and later, the @samp{#include} is not affected by the presence of a @samp{#line} referring to a different directory. We made this change because the old behavior caused problems when generated source files were transported between machines. For instance, it is common practice to ship generated parsers with a source release, so that people building the distribution do not need to have yacc or Bison installed. These files frequently have @samp{#line} directives referring to the directory tree of the system where the distribution was created. If GCC tries to search for headers in those directories, the build is likely to fail. The new behavior can cause failures too, if the generated file is not in the same directory as its source and it attempts to include a header which would be visible searching from the directory containing the source file. However, this problem is easily solved with an additional @option{-I} switch on the command line. The failures caused by the old semantics could sometimes be corrected only by editing the generated files, which is difficult and error-prone. @node Pragmas @chapter Pragmas The @samp{#pragma} directive is the method specified by the C standard for providing additional information to the compiler, beyond what is conveyed in the language itself. Three forms of this directive (commonly known as @dfn{pragmas}) are specified by the 1999 C standard. A C compiler is free to attach any meaning it likes to other pragmas. GCC has historically preferred to use extensions to the syntax of the language, such as @code{__attribute__}, for this purpose. However, GCC does define a few pragmas of its own. These mostly have effects on the entire translation unit or source file. In GCC version 3, all GNU-defined, supported pragmas have been given a @code{GCC} prefix. This is in line with the @code{STDC} prefix on all pragmas defined by C99. For backward compatibility, pragmas which were recognized by previous versions are still recognized without the @code{GCC} prefix, but that usage is deprecated. Some older pragmas are deprecated in their entirety. They are not recognized with the @code{GCC} prefix. @xref{Obsolete Features}. @cindex @code{_Pragma} C99 introduces the @code{@w{_Pragma}} operator. This feature addresses a major problem with @samp{#pragma}: being a directive, it cannot be produced as the result of macro expansion. @code{@w{_Pragma}} is an operator, much like @code{sizeof} or @code{defined}, and can be embedded in a macro. Its syntax is @code{@w{_Pragma (@var{string-literal})}}, where @var{string-literal} can be either a normal or wide-character string literal. It is destringized, by replacing all @samp{\\} with a single @samp{\} and all @samp{\"} with a @samp{"}. The result is then processed as if it had appeared as the right hand side of a @samp{#pragma} directive. For example, @smallexample _Pragma ("GCC dependency \"parse.y\"") @end smallexample @noindent has the same effect as @code{#pragma GCC dependency "parse.y"}. The same effect could be achieved using macros, for example @smallexample #define DO_PRAGMA(x) _Pragma (#x) DO_PRAGMA (GCC dependency "parse.y") @end smallexample The standard is unclear on where a @code{_Pragma} operator can appear. The preprocessor does not accept it within a preprocessing conditional directive like @samp{#if}. To be safe, you are probably best keeping it out of directives other than @samp{#define}, and putting it on a line of its own. This manual documents the pragmas which are meaningful to the preprocessor itself. Other pragmas are meaningful to the C or C++ compilers. They are documented in the GCC manual. @ftable @code @item #pragma GCC dependency @code{#pragma GCC dependency} allows you to check the relative dates of the current file and another file. If the other file is more recent than the current file, a warning is issued. This is useful if the current file is derived from the other file, and should be regenerated. The other file is searched for using the normal include search path. Optional trailing text can be used to give more information in the warning message. @smallexample #pragma GCC dependency "parse.y" #pragma GCC dependency "/usr/include/time.h" rerun fixincludes @end smallexample @item #pragma GCC poison Sometimes, there is an identifier that you want to remove completely from your program, and make sure that it never creeps back in. To enforce this, you can @dfn{poison} the identifier with this pragma. @code{#pragma GCC poison} is followed by a list of identifiers to poison. If any of those identifiers appears anywhere in the source after the directive, it is a hard error. For example, @smallexample #pragma GCC poison printf sprintf fprintf sprintf(some_string, "hello"); @end smallexample @noindent will produce an error. If a poisoned identifier appears as part of the expansion of a macro which was defined before the identifier was poisoned, it will @emph{not} cause an error. This lets you poison an identifier without worrying about system headers defining macros that use it. For example, @smallexample #define strrchr rindex #pragma GCC poison rindex strrchr(some_string, 'h'); @end smallexample @noindent will not produce an error. @item #pragma GCC system_header This pragma takes no arguments. It causes the rest of the code in the current file to be treated as if it came from a system header. @xref{System Headers}. @end ftable @node Other Directives @chapter Other Directives @findex #ident @findex #sccs The @samp{#ident} directive takes one argument, a string constant. On some systems, that string constant is copied into a special segment of the object file. On other systems, the directive is ignored. The @samp{#sccs} directive is a synonym for @samp{#ident}. These directives are not part of the C standard, but they are not official GNU extensions either. What historical information we have been able to find, suggests they originated with System V@. @cindex null directive The @dfn{null directive} consists of a @samp{#} followed by a newline, with only whitespace (including comments) in between. A null directive is understood as a preprocessing directive but has no effect on the preprocessor output. The primary significance of the existence of the null directive is that an input line consisting of just a @samp{#} will produce no output, rather than a line of output containing just a @samp{#}. Supposedly some old C programs contain such lines. @node Preprocessor Output @chapter Preprocessor Output -When the C preprocessor is used with the C, C++, or Objective-C -compilers, it is integrated into the compiler and communicates a stream -of binary tokens directly to the compiler's parser. However, it can -also be used in the more conventional standalone mode, where it produces -textual output. +When the C preprocessor is used with the C or C++ compilers, it is +integrated into the compiler and communicates a stream of binary tokens +directly to the compiler's parser. However, it can also be used in the +more conventional standalone mode, where it produces textual output. @c FIXME: Document the library interface. @cindex output format The output from the C preprocessor looks much like the input, except that all preprocessing directive lines have been replaced with blank lines and all comments with spaces. Long runs of blank lines are discarded. The ISO standard specifies that it is implementation defined whether a preprocessor preserves whitespace between tokens, or replaces it with e.g.@: a single space. In GNU CPP, whitespace between tokens is collapsed to become a single space, with the exception that the first token on a non-directive line is preceded with sufficient spaces that it appears in the same column in the preprocessed output that it appeared in the original source file. This is so the output is easy to read. @xref{Differences from previous versions}. CPP does not insert any whitespace where there was none in the original source, except where necessary to prevent an accidental token paste. @cindex linemarkers Source file name and line number information is conveyed by lines of the form @smallexample # @var{linenum} @var{filename} @var{flags} @end smallexample @noindent These are called @dfn{linemarkers}. They are inserted as needed into the output (but never within a string or character constant). They mean that the following line originated in file @var{filename} at line @var{linenum}. @var{filename} will never contain any non-printing characters; they are replaced with octal escape sequences. After the file name comes zero or more flags, which are @samp{1}, @samp{2}, @samp{3}, or @samp{4}. If there are multiple flags, spaces separate them. Here is what the flags mean: @table @samp @item 1 This indicates the start of a new file. @item 2 This indicates returning to a file (after having included another file). @item 3 This indicates that the following text comes from a system header file, so certain warnings should be suppressed. @item 4 This indicates that the following text should be treated as being wrapped in an implicit @code{extern "C"} block. @c maybe cross reference NO_IMPLICIT_EXTERN_C @end table As an extension, the preprocessor accepts linemarkers in non-assembler input files. They are treated like the corresponding @samp{#line} directive, (@pxref{Line Control}), except that trailing flags are permitted, and are interpreted with the meanings described above. If multiple flags are given, they must be in ascending order. Some directives may be duplicated in the output of the preprocessor. These are @samp{#ident} (always), @samp{#pragma} (only if the preprocessor does not handle the pragma itself), and @samp{#define} and @samp{#undef} (with certain debugging options). If this happens, the @samp{#} of the directive will always be in the first column, and there will be no space between the @samp{#} and the directive name. If macro expansion happens to generate tokens which might be mistaken for a duplicated directive, a space will be inserted between the @samp{#} and the directive name. @node Traditional Mode @chapter Traditional Mode Traditional (pre-standard) C preprocessing is rather different from the preprocessing specified by the standard. When GCC is given the @option{-traditional-cpp} option, it attempts to emulate a traditional preprocessor. GCC versions 3.2 and later only support traditional mode semantics in the preprocessor, and not in the compiler front ends. This chapter outlines the traditional preprocessor semantics we implemented. The implementation does not correspond precisely to the behavior of earlier versions of GCC, nor to any true traditional preprocessor. After all, inconsistencies among traditional implementations were a major motivation for C standardization. However, we intend that it should be compatible with true traditional preprocessors in all ways that actually matter. @menu * Traditional lexical analysis:: * Traditional macros:: * Traditional miscellany:: * Traditional warnings:: @end menu @node Traditional lexical analysis @section Traditional lexical analysis The traditional preprocessor does not decompose its input into tokens the same way a standards-conforming preprocessor does. The input is simply treated as a stream of text with minimal internal form. This implementation does not treat trigraphs (@pxref{trigraphs}) specially since they were an invention of the standards committee. It handles arbitrarily-positioned escaped newlines properly and splices the lines as you would expect; many traditional preprocessors did not do this. The form of horizontal whitespace in the input file is preserved in the output. In particular, hard tabs remain hard tabs. This can be useful if, for example, you are preprocessing a Makefile. Traditional CPP only recognizes C-style block comments, and treats the @samp{/*} sequence as introducing a comment only if it lies outside quoted text. Quoted text is introduced by the usual single and double quotes, and also by an initial @samp{<} in a @code{#include} directive. Traditionally, comments are completely removed and are not replaced with a space. Since a traditional compiler does its own tokenization of the output of the preprocessor, this means that comments can effectively be used as token paste operators. However, comments behave like separators for text handled by the preprocessor itself, since it doesn't re-lex its input. For example, in @smallexample #if foo/**/bar @end smallexample @noindent @samp{foo} and @samp{bar} are distinct identifiers and expanded separately if they happen to be macros. In other words, this directive is equivalent to @smallexample #if foo bar @end smallexample @noindent rather than @smallexample #if foobar @end smallexample Generally speaking, in traditional mode an opening quote need not have a matching closing quote. In particular, a macro may be defined with replacement text that contains an unmatched quote. Of course, if you attempt to compile preprocessed output containing an unmatched quote you will get a syntax error. However, all preprocessing directives other than @code{#define} require matching quotes. For example: @smallexample #define m This macro's fine and has an unmatched quote "/* This is not a comment. */ /* @r{This is a comment. The following #include directive is ill-formed.} */ #include } character. Note that we don't allow the terminators of header names to be escaped; the first @samp{"} or @samp{>} terminates the header name. Interpretation of some character sequences depends upon whether we are -lexing C, C++ or Objective-C, and on the revision of the standard in -force. For example, @samp{::} is a single token in C++, but in C it is -two separate @samp{:} tokens and almost certainly a syntax error. Such +lexing C or C++, and on the revision of the standard in force. For +example, @samp{::} is a single token in C++, but in C it is two +separate @samp{:} tokens and almost certainly a syntax error. Such cases are handled by @code{_cpp_lex_direct} based upon command-line flags stored in the @code{cpp_options} structure. Once a token has been lexed, it leads an independent existence. The spelling of numbers, identifiers and strings is copied to permanent storage from the original input buffer, so a token remains valid and correct even if its source buffer is freed with @code{_cpp_pop_buffer}. The storage holding the spellings of such tokens remains until the client program calls cpp_destroy, probably at the end of the translation unit. @anchor{Lexing a line} @section Lexing a line @cindex token run When the preprocessor was changed to return pointers to tokens, one feature I wanted was some sort of guarantee regarding how long a returned pointer remains valid. This is important to the stand-alone preprocessor, the future direction of the C family front ends, and even to cpplib itself internally. Occasionally the preprocessor wants to be able to peek ahead in the token stream. For example, after the name of a function-like macro, it wants to check the next token to see if it is an opening parenthesis. Another example is that, after reading the first few tokens of a @code{#pragma} directive and not recognizing it as a registered pragma, it wants to backtrack and allow the user-defined handler for unknown pragmas to access the full @code{#pragma} token stream. The stand-alone preprocessor wants to be able to test the current token with the previous one to see if a space needs to be inserted to preserve their separate tokenization upon re-lexing (paste avoidance), so it needs to be sure the pointer to the previous token is still valid. The recursive-descent C++ parser wants to be able to perform tentative parsing arbitrarily far ahead in the token stream, and then to be able to jump back to a prior position in that stream if necessary. The rule I chose, which is fairly natural, is to arrange that the preprocessor lex all tokens on a line consecutively into a token buffer, which I call a @dfn{token run}, and when meeting an unescaped new line (newlines within comments do not count either), to start lexing back at the beginning of the run. Note that we do @emph{not} lex a line of tokens at once; if we did that @code{parse_identifier} would not have state flags available to warn about invalid identifiers (@pxref{Invalid identifiers}). In other words, accessing tokens that appeared earlier in the current line is valid, but since each logical line overwrites the tokens of the previous line, tokens from prior lines are unavailable. In particular, since a directive only occupies a single logical line, this means that the directive handlers like the @code{#pragma} handler can jump around in the directive's tokens if necessary. Two issues remain: what about tokens that arise from macro expansions, and what happens when we have a long line that overflows the token run? Since we promise clients that we preserve the validity of pointers that we have already returned for tokens that appeared earlier in the line, we cannot reallocate the run. Instead, on overflow it is expanded by chaining a new token run on to the end of the existing one. The tokens forming a macro's replacement list are collected by the @code{#define} handler, and placed in storage that is only freed by @code{cpp_destroy}. So if a macro is expanded in the line of tokens, the pointers to the tokens of its expansion that are returned will always remain valid. However, macros are a little trickier than that, since they give rise to three sources of fresh tokens. They are the built-in macros like @code{__LINE__}, and the @samp{#} and @samp{##} operators for stringification and token pasting. I handled this by allocating space for these tokens from the lexer's token run chain. This means they automatically receive the same lifetime guarantees as lexed tokens, and we don't need to concern ourselves with freeing them. Lexing into a line of tokens solves some of the token memory management issues, but not all. The opening parenthesis after a function-like macro name might lie on a different line, and the front ends definitely want the ability to look ahead past the end of the current line. So cpplib only moves back to the start of the token run at the end of a line if the variable @code{keep_tokens} is zero. Line-buffering is quite natural for the preprocessor, and as a result the only time cpplib needs to increment this variable is whilst looking for the opening parenthesis to, and reading the arguments of, a function-like macro. In the near future cpplib will export an interface to increment and decrement this variable, so that clients can share full control over the lifetime of token pointers too. The routine @code{_cpp_lex_token} handles moving to new token runs, calling @code{_cpp_lex_direct} to lex new tokens, or returning previously-lexed tokens if we stepped back in the token stream. It also checks each token for the @code{BOL} flag, which might indicate a directive that needs to be handled, or require a start-of-line call-back to be made. @code{_cpp_lex_token} also handles skipping over tokens in failed conditional blocks, and invalidates the control macro of the multiple-include optimization if a token was successfully lexed outside a directive. In other words, its callers do not need to concern themselves with such issues. @node Hash Nodes @unnumbered Hash Nodes @cindex hash table @cindex identifiers @cindex macros @cindex assertions @cindex named operators When cpplib encounters an ``identifier'', it generates a hash code for it and stores it in the hash table. By ``identifier'' we mean tokens with type @code{CPP_NAME}; this includes identifiers in the usual C sense, as well as keywords, directive names, macro names and so on. For example, all of @code{pragma}, @code{int}, @code{foo} and @code{__GNUC__} are identifiers and hashed when lexed. Each node in the hash table contain various information about the identifier it represents. For example, its length and type. At any one time, each identifier falls into exactly one of three categories: @itemize @bullet @item Macros These have been declared to be macros, either on the command line or with @code{#define}. A few, such as @code{__TIME__} are built-ins entered in the hash table during initialization. The hash node for a normal macro points to a structure with more information about the macro, such as whether it is function-like, how many arguments it takes, and its expansion. Built-in macros are flagged as special, and instead contain an enum indicating which of the various built-in macros it is. @item Assertions Assertions are in a separate namespace to macros. To enforce this, cpp actually prepends a @code{#} character before hashing and entering it in the hash table. An assertion's node points to a chain of answers to that assertion. @item Void Everything else falls into this category---an identifier that is not currently a macro, or a macro that has since been undefined with @code{#undef}. When preprocessing C++, this category also includes the named operators, such as @code{xor}. In expressions these behave like the operators they represent, but in contexts where the spelling of a token matters they are spelt differently. This spelling distinction is relevant when they are operands of the stringizing and pasting macro operators @code{#} and @code{##}. Named operator hash nodes are flagged, both to catch the spelling distinction and to prevent them from being defined as macros. @end itemize The same identifiers share the same hash node. Since each identifier token, after lexing, contains a pointer to its hash node, this is used to provide rapid lookup of various information. For example, when parsing a @code{#define} statement, CPP flags each argument's identifier hash node with the index of that argument. This makes duplicated argument checking an O(1) operation for each argument. Similarly, for each identifier in the macro's expansion, lookup to see if it is an argument, and which argument it is, is also an O(1) operation. Further, each directive name, such as @code{endif}, has an associated directive enum stored in its hash node, so that directive lookup is also O(1). @node Macro Expansion @unnumbered Macro Expansion Algorithm @cindex macro expansion Macro expansion is a tricky operation, fraught with nasty corner cases and situations that render what you thought was a nifty way to optimize the preprocessor's expansion algorithm wrong in quite subtle ways. I strongly recommend you have a good grasp of how the C and C++ standards require macros to be expanded before diving into this section, let alone the code!. If you don't have a clear mental picture of how things like nested macro expansion, stringification and token pasting are supposed to work, damage to your sanity can quickly result. @section Internal representation of macros @cindex macro representation (internal) The preprocessor stores macro expansions in tokenized form. This saves repeated lexing passes during expansion, at the cost of a small increase in memory consumption on average. The tokens are stored contiguously in memory, so a pointer to the first one and a token count is all you need to get the replacement list of a macro. If the macro is a function-like macro the preprocessor also stores its parameters, in the form of an ordered list of pointers to the hash table entry of each parameter's identifier. Further, in the macro's stored expansion each occurrence of a parameter is replaced with a special token of type @code{CPP_MACRO_ARG}. Each such token holds the index of the parameter it represents in the parameter list, which allows rapid replacement of parameters with their arguments during expansion. Despite this optimization it is still necessary to store the original parameters to the macro, both for dumping with e.g., @option{-dD}, and to warn about non-trivial macro redefinitions when the parameter names have changed. @section Macro expansion overview The preprocessor maintains a @dfn{context stack}, implemented as a linked list of @code{cpp_context} structures, which together represent the macro expansion state at any one time. The @code{struct cpp_reader} member variable @code{context} points to the current top of this stack. The top normally holds the unexpanded replacement list of the innermost macro under expansion, except when cpplib is about to pre-expand an argument, in which case it holds that argument's unexpanded tokens. When there are no macros under expansion, cpplib is in @dfn{base context}. All contexts other than the base context contain a contiguous list of tokens delimited by a starting and ending token. When not in base context, cpplib obtains the next token from the list of the top context. If there are no tokens left in the list, it pops that context off the stack, and subsequent ones if necessary, until an unexhausted context is found or it returns to base context. In base context, cpplib reads tokens directly from the lexer. If it encounters an identifier that is both a macro and enabled for expansion, cpplib prepares to push a new context for that macro on the stack by calling the routine @code{enter_macro_context}. When this routine returns, the new context will contain the unexpanded tokens of the replacement list of that macro. In the case of function-like macros, @code{enter_macro_context} also replaces any parameters in the replacement list, stored as @code{CPP_MACRO_ARG} tokens, with the appropriate macro argument. If the standard requires that the parameter be replaced with its expanded argument, the argument will have been fully macro expanded first. @code{enter_macro_context} also handles special macros like @code{__LINE__}. Although these macros expand to a single token which cannot contain any further macros, for reasons of token spacing (@pxref{Token Spacing}) and simplicity of implementation, cpplib handles these special macros by pushing a context containing just that one token. The final thing that @code{enter_macro_context} does before returning is to mark the macro disabled for expansion (except for special macros like @code{__TIME__}). The macro is re-enabled when its context is later popped from the context stack, as described above. This strict ordering ensures that a macro is disabled whilst its expansion is being scanned, but that it is @emph{not} disabled whilst any arguments to it are being expanded. @section Scanning the replacement list for macros to expand The C standard states that, after any parameters have been replaced with their possibly-expanded arguments, the replacement list is scanned for nested macros. Further, any identifiers in the replacement list that are not expanded during this scan are never again eligible for expansion in the future, if the reason they were not expanded is that the macro in question was disabled. Clearly this latter condition can only apply to tokens resulting from argument pre-expansion. Other tokens never have an opportunity to be re-tested for expansion. It is possible for identifiers that are function-like macros to not expand initially but to expand during a later scan. This occurs when the identifier is the last token of an argument (and therefore originally followed by a comma or a closing parenthesis in its macro's argument list), and when it replaces its parameter in the macro's replacement list, the subsequent token happens to be an opening parenthesis (itself possibly the first token of an argument). It is important to note that when cpplib reads the last token of a given context, that context still remains on the stack. Only when looking for the @emph{next} token do we pop it off the stack and drop to a lower context. This makes backing up by one token easy, but more importantly ensures that the macro corresponding to the current context is still disabled when we are considering the last token of its replacement list for expansion (or indeed expanding it). As an example, which illustrates many of the points above, consider @smallexample #define foo(x) bar x foo(foo) (2) @end smallexample @noindent which fully expands to @samp{bar foo (2)}. During pre-expansion of the argument, @samp{foo} does not expand even though the macro is enabled, since it has no following parenthesis [pre-expansion of an argument only uses tokens from that argument; it cannot take tokens from whatever follows the macro invocation]. This still leaves the argument token @samp{foo} eligible for future expansion. Then, when re-scanning after argument replacement, the token @samp{foo} is rejected for expansion, and marked ineligible for future expansion, since the macro is now disabled. It is disabled because the replacement list @samp{bar foo} of the macro is still on the context stack. If instead the algorithm looked for an opening parenthesis first and then tested whether the macro were disabled it would be subtly wrong. In the example above, the replacement list of @samp{foo} would be popped in the process of finding the parenthesis, re-enabling @samp{foo} and expanding it a second time. @section Looking for a function-like macro's opening parenthesis Function-like macros only expand when immediately followed by a parenthesis. To do this cpplib needs to temporarily disable macros and read the next token. Unfortunately, because of spacing issues (@pxref{Token Spacing}), there can be fake padding tokens in-between, and if the next real token is not a parenthesis cpplib needs to be able to back up that one token as well as retain the information in any intervening padding tokens. Backing up more than one token when macros are involved is not permitted by cpplib, because in general it might involve issues like restoring popped contexts onto the context stack, which are too hard. Instead, searching for the parenthesis is handled by a special function, @code{funlike_invocation_p}, which remembers padding information as it reads tokens. If the next real token is not an opening parenthesis, it backs up that one token, and then pushes an extra context just containing the padding information if necessary. @section Marking tokens ineligible for future expansion As discussed above, cpplib needs a way of marking tokens as unexpandable. Since the tokens cpplib handles are read-only once they have been lexed, it instead makes a copy of the token and adds the flag @code{NO_EXPAND} to the copy. For efficiency and to simplify memory management by avoiding having to remember to free these tokens, they are allocated as temporary tokens from the lexer's current token run (@pxref{Lexing a line}) using the function @code{_cpp_temp_token}. The tokens are then re-used once the current line of tokens has been read in. This might sound unsafe. However, tokens runs are not re-used at the end of a line if it happens to be in the middle of a macro argument list, and cpplib only wants to back-up more than one lexer token in situations where no macro expansion is involved, so the optimization is safe. @node Token Spacing @unnumbered Token Spacing @cindex paste avoidance @cindex spacing @cindex token spacing First, consider an issue that only concerns the stand-alone preprocessor: there needs to be a guarantee that re-reading its preprocessed output results in an identical token stream. Without taking special measures, this might not be the case because of macro substitution. For example: @smallexample #define PLUS + #define EMPTY #define f(x) =x= +PLUS -EMPTY- PLUS+ f(=) @expansion{} + + - - + + = = = @emph{not} @expansion{} ++ -- ++ === @end smallexample One solution would be to simply insert a space between all adjacent tokens. However, we would like to keep space insertion to a minimum, both for aesthetic reasons and because it causes problems for people who still try to abuse the preprocessor for things like Fortran source and Makefiles. For now, just notice that when tokens are added (or removed, as shown by the @code{EMPTY} example) from the original lexed token stream, we need to check for accidental token pasting. We call this @dfn{paste avoidance}. Token addition and removal can only occur because of macro expansion, but accidental pasting can occur in many places: both before and after each macro replacement, each argument replacement, and additionally each token created by the @samp{#} and @samp{##} operators. Look at how the preprocessor gets whitespace output correct normally. The @code{cpp_token} structure contains a flags byte, and one of those flags is @code{PREV_WHITE}. This is flagged by the lexer, and indicates that the token was preceded by whitespace of some form other than a new line. The stand-alone preprocessor can use this flag to decide whether to insert a space between tokens in the output. Now consider the result of the following macro expansion: @smallexample #define add(x, y, z) x + y +z; sum = add (1,2, 3); @expansion{} sum = 1 + 2 +3; @end smallexample The interesting thing here is that the tokens @samp{1} and @samp{2} are output with a preceding space, and @samp{3} is output without a preceding space, but when lexed none of these tokens had that property. Careful consideration reveals that @samp{1} gets its preceding whitespace from the space preceding @samp{add} in the macro invocation, @emph{not} replacement list. @samp{2} gets its whitespace from the space preceding the parameter @samp{y} in the macro replacement list, and @samp{3} has no preceding space because parameter @samp{z} has none in the replacement list. Once lexed, tokens are effectively fixed and cannot be altered, since pointers to them might be held in many places, in particular by in-progress macro expansions. So instead of modifying the two tokens above, the preprocessor inserts a special token, which I call a @dfn{padding token}, into the token stream to indicate that spacing of the subsequent token is special. The preprocessor inserts padding tokens in front of every macro expansion and expanded macro argument. These point to a @dfn{source token} from which the subsequent real token should inherit its spacing. In the above example, the source tokens are @samp{add} in the macro invocation, and @samp{y} and @samp{z} in the macro replacement list, respectively. It is quite easy to get multiple padding tokens in a row, for example if a macro's first replacement token expands straight into another macro. @smallexample #define foo bar #define bar baz [foo] @expansion{} [baz] @end smallexample Here, two padding tokens are generated with sources the @samp{foo} token between the brackets, and the @samp{bar} token from foo's replacement list, respectively. Clearly the first padding token is the one to use, so the output code should contain a rule that the first padding token in a sequence is the one that matters. But what if a macro expansion is left? Adjusting the above example slightly: @smallexample #define foo bar #define bar EMPTY baz #define EMPTY [foo] EMPTY; @expansion{} [ baz] ; @end smallexample As shown, now there should be a space before @samp{baz} and the semicolon in the output. The rules we decided above fail for @samp{baz}: we generate three padding tokens, one per macro invocation, before the token @samp{baz}. We would then have it take its spacing from the first of these, which carries source token @samp{foo} with no leading space. It is vital that cpplib get spacing correct in these examples since any of these macro expansions could be stringified, where spacing matters. So, this demonstrates that not just entering macro and argument expansions, but leaving them requires special handling too. I made cpplib insert a padding token with a @code{NULL} source token when leaving macro expansions, as well as after each replaced argument in a macro's replacement list. It also inserts appropriate padding tokens on either side of tokens created by the @samp{#} and @samp{##} operators. I expanded the rule so that, if we see a padding token with a @code{NULL} source token, @emph{and} that source token has no leading space, then we behave as if we have seen no padding tokens at all. A quick check shows this rule will then get the above example correct as well. Now a relationship with paste avoidance is apparent: we have to be careful about paste avoidance in exactly the same locations we have padding tokens in order to get white space correct. This makes implementation of paste avoidance easy: wherever the stand-alone preprocessor is fixing up spacing because of padding tokens, and it turns out that no space is needed, it has to take the extra step to check that a space is not needed after all to avoid an accidental paste. The function @code{cpp_avoid_paste} advises whether a space is required between two consecutive tokens. To avoid excessive spacing, it tries hard to only require a space if one is likely to be necessary, but for reasons of efficiency it is slightly conservative and might recommend a space where one is not strictly needed. @node Line Numbering @unnumbered Line numbering @cindex line numbers @section Just which line number anyway? There are three reasonable requirements a cpplib client might have for the line number of a token passed to it: @itemize @bullet @item The source line it was lexed on. @item The line it is output on. This can be different to the line it was lexed on if, for example, there are intervening escaped newlines or C-style comments. For example: @smallexample foo /* @r{A long comment} */ bar \ baz @result{} foo bar baz @end smallexample @item If the token results from a macro expansion, the line of the macro name, or possibly the line of the closing parenthesis in the case of function-like macro expansion. @end itemize The @code{cpp_token} structure contains @code{line} and @code{col} members. The lexer fills these in with the line and column of the first character of the token. Consequently, but maybe unexpectedly, a token from the replacement list of a macro expansion carries the location of the token within the @code{#define} directive, because cpplib expands a macro by returning pointers to the tokens in its replacement list. The current implementation of cpplib assigns tokens created from built-in macros and the @samp{#} and @samp{##} operators the location of the most recently lexed token. This is a because they are allocated from the lexer's token runs, and because of the way the diagnostic routines infer the appropriate location to report. The diagnostic routines in cpplib display the location of the most recently @emph{lexed} token, unless they are passed a specific line and column to report. For diagnostics regarding tokens that arise from macro expansions, it might also be helpful for the user to see the original location in the macro definition that the token came from. Since that is exactly the information each token carries, such an enhancement could be made relatively easily in future. The stand-alone preprocessor faces a similar problem when determining the correct line to output the token on: the position attached to a token is fairly useless if the token came from a macro expansion. All tokens on a logical line should be output on its first physical line, so the token's reported location is also wrong if it is part of a physical line other than the first. To solve these issues, cpplib provides a callback that is generated whenever it lexes a preprocessing token that starts a new logical line other than a directive. It passes this token (which may be a @code{CPP_EOF} token indicating the end of the translation unit) to the callback routine, which can then use the line and column of this token to produce correct output. @section Representation of line numbers As mentioned above, cpplib stores with each token the line number that it was lexed on. In fact, this number is not the number of the line in the source file, but instead bears more resemblance to the number of the line in the translation unit. The preprocessor maintains a monotonic increasing line count, which is incremented at every new line character (and also at the end of any buffer that does not end in a new line). Since a line number of zero is useful to indicate certain special states and conditions, this variable starts counting from one. This variable therefore uniquely enumerates each line in the translation unit. With some simple infrastructure, it is straight forward to map from this to the original source file and line number pair, saving space whenever line number information needs to be saved. The code the implements this mapping lies in the files @file{line-map.c} and @file{line-map.h}. Command-line macros and assertions are implemented by pushing a buffer containing the right hand side of an equivalent @code{#define} or @code{#assert} directive. Some built-in macros are handled similarly. Since these are all processed before the first line of the main input file, it will typically have an assigned line closer to twenty than to one. @node Guard Macros @unnumbered The Multiple-Include Optimization @cindex guard macros @cindex controlling macros @cindex multiple-include optimization Header files are often of the form @smallexample #ifndef FOO #define FOO @dots{} #endif @end smallexample @noindent to prevent the compiler from processing them more than once. The preprocessor notices such header files, so that if the header file appears in a subsequent @code{#include} directive and @code{FOO} is defined, then it is ignored and it doesn't preprocess or even re-open the file a second time. This is referred to as the @dfn{multiple include optimization}. Under what circumstances is such an optimization valid? If the file were included a second time, it can only be optimized away if that inclusion would result in no tokens to return, and no relevant directives to process. Therefore the current implementation imposes requirements and makes some allowances as follows: @enumerate @item There must be no tokens outside the controlling @code{#if}-@code{#endif} pair, but whitespace and comments are permitted. @item There must be no directives outside the controlling directive pair, but the @dfn{null directive} (a line containing nothing other than a single @samp{#} and possibly whitespace) is permitted. @item The opening directive must be of the form @smallexample #ifndef FOO @end smallexample or @smallexample #if !defined FOO [equivalently, #if !defined(FOO)] @end smallexample @item In the second form above, the tokens forming the @code{#if} expression must have come directly from the source file---no macro expansion must have been involved. This is because macro definitions can change, and tracking whether or not a relevant change has been made is not worth the implementation cost. @item There can be no @code{#else} or @code{#elif} directives at the outer conditional block level, because they would probably contain something of interest to a subsequent pass. @end enumerate First, when pushing a new file on the buffer stack, @code{_stack_include_file} sets the controlling macro @code{mi_cmacro} to @code{NULL}, and sets @code{mi_valid} to @code{true}. This indicates that the preprocessor has not yet encountered anything that would invalidate the multiple-include optimization. As described in the next few paragraphs, these two variables having these values effectively indicates top-of-file. When about to return a token that is not part of a directive, @code{_cpp_lex_token} sets @code{mi_valid} to @code{false}. This enforces the constraint that tokens outside the controlling conditional block invalidate the optimization. The @code{do_if}, when appropriate, and @code{do_ifndef} directive handlers pass the controlling macro to the function @code{push_conditional}. cpplib maintains a stack of nested conditional blocks, and after processing every opening conditional this function pushes an @code{if_stack} structure onto the stack. In this structure it records the controlling macro for the block, provided there is one and we're at top-of-file (as described above). If an @code{#elif} or @code{#else} directive is encountered, the controlling macro for that block is cleared to @code{NULL}. Otherwise, it survives until the @code{#endif} closing the block, upon which @code{do_endif} sets @code{mi_valid} to true and stores the controlling macro in @code{mi_cmacro}. @code{_cpp_handle_directive} clears @code{mi_valid} when processing any directive other than an opening conditional and the null directive. With this, and requiring top-of-file to record a controlling macro, and no @code{#else} or @code{#elif} for it to survive and be copied to @code{mi_cmacro} by @code{do_endif}, we have enforced the absence of directives outside the main conditional block for the optimization to be on. Note that whilst we are inside the conditional block, @code{mi_valid} is likely to be reset to @code{false}, but this does not matter since the closing @code{#endif} restores it to @code{true} if appropriate. Finally, since @code{_cpp_lex_direct} pops the file off the buffer stack at @code{EOF} without returning a token, if the @code{#endif} directive was not followed by any tokens, @code{mi_valid} is @code{true} and @code{_cpp_pop_file_buffer} remembers the controlling macro associated with the file. Subsequent calls to @code{stack_include_file} result in no buffer being pushed if the controlling macro is defined, effecting the optimization. A quick word on how we handle the @smallexample #if !defined FOO @end smallexample @noindent case. @code{_cpp_parse_expr} and @code{parse_defined} take steps to see whether the three stages @samp{!}, @samp{defined-expression} and @samp{end-of-directive} occur in order in a @code{#if} expression. If so, they return the guard macro to @code{do_if} in the variable @code{mi_ind_cmacro}, and otherwise set it to @code{NULL}. @code{enter_macro_context} sets @code{mi_valid} to false, so if a macro was expanded whilst parsing any part of the expression, then the top-of-file test in @code{push_conditional} fails and the optimization is turned off. @node Files @unnumbered File Handling @cindex files Fairly obviously, the file handling code of cpplib resides in the file @file{files.c}. It takes care of the details of file searching, opening, reading and caching, for both the main source file and all the headers it recursively includes. The basic strategy is to minimize the number of system calls. On many systems, the basic @code{open ()} and @code{fstat ()} system calls can be quite expensive. For every @code{#include}-d file, we need to try all the directories in the search path until we find a match. Some projects, such as glibc, pass twenty or thirty include paths on the command line, so this can rapidly become time consuming. For a header file we have not encountered before we have little choice but to do this. However, it is often the case that the same headers are repeatedly included, and in these cases we try to avoid repeating the filesystem queries whilst searching for the correct file. For each file we try to open, we store the constructed path in a splay tree. This path first undergoes simplification by the function @code{_cpp_simplify_pathname}. For example, @file{/usr/include/bits/../foo.h} is simplified to @file{/usr/include/foo.h} before we enter it in the splay tree and try to @code{open ()} the file. CPP will then find subsequent uses of @file{foo.h}, even as @file{/usr/include/foo.h}, in the splay tree and save system calls. Further, it is likely the file contents have also been cached, saving a @code{read ()} system call. We don't bother caching the contents of header files that are re-inclusion protected, and whose re-inclusion macro is defined when we leave the header file for the first time. If the host supports it, we try to map suitably large files into memory, rather than reading them in directly. The include paths are internally stored on a null-terminated singly-linked list, starting with the @code{"header.h"} directory search chain, which then links into the @code{} directory chain. Files included with the @code{} syntax start the lookup directly in the second half of this chain. However, files included with the @code{"foo.h"} syntax start at the beginning of the chain, but with one extra directory prepended. This is the directory of the current file; the one containing the @code{#include} directive. Prepending this directory on a per-file basis is handled by the function @code{search_from}. Note that a header included with a directory component, such as @code{#include "mydir/foo.h"} and opened as @file{/usr/local/include/mydir/foo.h}, will have the complete path minus the basename @samp{foo.h} as the current directory. Enough information is stored in the splay tree that CPP can immediately tell whether it can skip the header file because of the multiple include optimization, whether the file didn't exist or couldn't be opened for some reason, or whether the header was flagged not to be re-used, as it is with the obsolete @code{#import} directive. For the benefit of MS-DOS filesystems with an 8.3 filename limitation, CPP offers the ability to treat various include file names as aliases for the real header files with shorter names. The map from one to the other is found in a special file called @samp{header.gcc}, stored in the command line (or system) include directories to which the mapping applies. This may be higher up the directory tree than the full path to the file minus the base name. @node Concept Index @unnumbered Concept Index @printindex cp @bye Index: head/contrib/gcc/doc/cppopts.texi =================================================================== --- head/contrib/gcc/doc/cppopts.texi (revision 220754) +++ head/contrib/gcc/doc/cppopts.texi (revision 220755) @@ -1,746 +1,744 @@ @c Copyright (c) 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006 @c Free Software Foundation, Inc. @c This is part of the CPP and GCC manuals. @c For copying conditions, see the file gcc.texi. @c --------------------------------------------------------------------- @c Options affecting the preprocessor @c --------------------------------------------------------------------- @c If this file is included with the flag ``cppmanual'' set, it is @c formatted for inclusion in the CPP manual; otherwise the main GCC manual. @table @gcctabopt @item -D @var{name} @opindex D Predefine @var{name} as a macro, with definition @code{1}. @item -D @var{name}=@var{definition} The contents of @var{definition} are tokenized and processed as if they appeared during translation phase three in a @samp{#define} directive.

A macro is @dfn{used} if it is expanded or tested for existence at least once. The preprocessor will also warn if the macro has not been used at the time it is redefined or undefined. Built-in macros, macros defined on the command line, and macros defined in include files are not warned about. @emph{Note:} If a macro is actually used, but only used in skipped conditional blocks, then CPP will report it as unused. To avoid the warning in such a case, you might improve the scope of the macro's definition by, for example, moving it into the first skipped block. Alternatively, you could provide a dummy use with something like: @smallexample #if defined the_macro_causing_the_warning #endif @end smallexample @item -Wendif-labels @opindex Wendif-labels Warn whenever an @samp{#else} or an @samp{#endif} are followed by text.

If you are responsible for the system library, you may want to see them. @item -w @opindex w Suppress all warnings, including those which GNU CPP issues by default. @item -pedantic @opindex pedantic Issue all the mandatory diagnostics listed in the C standard. Some of them are left out by default, since they trigger frequently on harmless code. @item -pedantic-errors @opindex pedantic-errors Issue all the mandatory diagnostics, and make all mandatory diagnostics into errors. This includes mandatory diagnostics that GCC issues without @samp{-pedantic} but treats as warnings. @item -M @opindex M @cindex make @cindex dependencies, make Instead of outputting the result of preprocessing, output a rule suitable for @command{make} describing the dependencies of the main source file. The preprocessor outputs one @command{make} rule containing the object file name for that source file, a colon, and the names of all the included files, including those coming from @option{-include} or @option{-imacros} command line options. Unless specified explicitly (with @option{-MT} or @option{-MQ}), the object file name consists of the basename of the source file with any suffix replaced with object file suffix. If there are many included files then the rule is split into several lines using @samp{\}-newline. The rule has no commands. This option does not suppress the preprocessor's debug output, such as @option{-dM}. To avoid mixing such debug output with the dependency rules you should explicitly specify the dependency output file with @option{-MF}, or use an environment variable like @env{DEPENDENCIES_OUTPUT} (@pxref{Environment Variables}). Debug output will still be sent to the regular output stream as normal. Passing @option{-M} to the driver implies @option{-E}, and suppresses warnings with an implicit @option{-w}. @item -MM @opindex MM Like @option{-M} but do not mention header files that are found in system header directories, nor header files that are included, directly or indirectly, from such a header. This implies that the choice of angle brackets or double quotes in an @samp{#include} directive does not in itself determine whether that header will appear in @option{-MM} dependency output. This is a slight change in semantics from GCC versions 3.0 and earlier. @anchor{dashMF} @item -MF @var{file} @opindex MF When used with @option{-M} or @option{-MM}, specifies a file to write the dependencies to. If no @option{-MF} switch is given the preprocessor sends the rules to the same place it would have sent preprocessed output. When used with the driver options @option{-MD} or @option{-MMD}, @option{-MF} overrides the default dependency output file. @item -MG @opindex MG In conjunction with an option such as @option{-M} requesting dependency generation, @option{-MG} assumes missing header files are generated files and adds them to the dependency list without raising an error. The dependency filename is taken directly from the @code{#include} directive without prepending any path. @option{-MG} also suppresses preprocessed output, as a missing header file renders this useless. This feature is used in automatic updating of makefiles. @item -MP @opindex MP This option instructs CPP to add a phony target for each dependency other than the main file, causing each to depend on nothing. These dummy rules work around errors @command{make} gives if you remove header files without updating the @file{Makefile} to match. This is typical output: @smallexample test.o: test.c test.h test.h: @end smallexample @item -MT @var{target} @opindex MT Change the target of the rule emitted by dependency generation. By default CPP takes the name of the main input file, including any path, deletes any file suffix such as @samp{.c}, and appends the platform's usual object suffix. The result is the target. An @option{-MT} option will set the target to be exactly the string you specify. If you want multiple targets, you can specify them as a single argument to @option{-MT}, or use multiple @option{-MT} options. For example, @option{@w{-MT '$(objpfx)foo.o'}} might give @smallexample $(objpfx)foo.o: foo.c @end smallexample @item -MQ @var{target} @opindex MQ Same as @option{-MT}, but it quotes any characters which are special to Make. @option{@w{-MQ '$(objpfx)foo.o'}} gives @smallexample $$(objpfx)foo.o: foo.c @end smallexample The default target is automatically quoted, as if it were given with @option{-MQ}. @item -MD @opindex MD @option{-MD} is equivalent to @option{-M -MF @var{file}}, except that @option{-E} is not implied. The driver determines @var{file} based on whether an @option{-o} option is given. If it is, the driver uses its argument but with a suffix of @file{.d}, otherwise it take the basename of the input file and applies a @file{.d} suffix. If @option{-MD} is used in conjunction with @option{-E}, any @option{-o} switch is understood to specify the dependency output file (@pxref{dashMF,,-MF}), but if used without @option{-E}, each @option{-o} is understood to specify a target object file. Since @option{-E} is not implied, @option{-MD} can be used to generate a dependency output file as a side-effect of the compilation process. @item -MMD @opindex MMD Like @option{-MD} except mention only user header files, not system header files. @ifclear cppmanual @item -fpch-deps @opindex fpch-deps When using precompiled headers (@pxref{Precompiled Headers}), this flag will cause the dependency-output flags to also list the files from the precompiled header's dependencies. If not specified only the precompiled header would be listed and not the files that were used to create it because those files are not consulted when a precompiled header is used. @item -fpch-preprocess @opindex fpch-preprocess This option allows use of a precompiled header (@pxref{Precompiled Headers}) together with @option{-E}. It inserts a special @code{#pragma}, @code{#pragma GCC pch_preprocess ""} in the output to mark the place where the precompiled header was found, and its filename. When @option{-fpreprocessed} is in use, GCC recognizes this @code{#pragma} and loads the PCH@. This option is off by default, because the resulting preprocessed output is only really suitable as input to GCC@. It is switched on by @option{-save-temps}. You should not write this @code{#pragma} in your own code, but it is safe to edit the filename if the PCH file is available in a different location. The filename may be absolute or it may be relative to GCC's current directory. @end ifclear @item -x c @itemx -x c++ -@itemx -x objective-c @itemx -x assembler-with-cpp @opindex x -Specify the source language: C, C++, Objective-C, or assembly.

This option has been removed, because it conflicts with the @option{-l} option. @item -std=@var{standard} @itemx -ansi @opindex ansi @opindex std= Specify the standard to which the code should conform. Currently CPP knows about C and C++ standards; others may be added in the future. @var{standard} may be one of: @table @code @item iso9899:1990 @itemx c89 The ISO C standard from 1990. @samp{c89} is the customary shorthand for this version of the standard. The @option{-ansi} option is equivalent to @option{-std=c89}. @item iso9899:199409 The 1990 C standard, as amended in 1994. @item iso9899:1999 @itemx c99 @itemx iso9899:199x @itemx c9x The revised ISO C standard, published in December 1999. Before publication, this was known as C9X@. @item gnu89 The 1990 C standard plus GNU extensions. This is the default. @item gnu99 @itemx gnu9x The 1999 C standard plus GNU extensions. @item c++98 The 1998 ISO C++ standard plus amendments. @item gnu++98 The same as @option{-std=c++98} plus GNU extensions. This is the default for C++ code. @end table @item -I- @opindex I- Split the include path. Any directories specified with @option{-I} options before @option{-I-} are searched only for headers requested with @code{@w{#include "@var{file}"}}; they are not searched for @code{@w{#include <@var{file}>}}. If additional directories are specified with @option{-I} options after the @option{-I-}, those directories are searched for all @samp{#include} directives. In addition, @option{-I-} inhibits the use of the directory of the current file directory as the first search directory for @code{@w{#include "@var{file}"}}. @ifset cppmanual @xref{Search Path}. @end ifset This option has been deprecated. @item -nostdinc @opindex nostdinc Do not search the standard system directories for header files. Only the directories you have specified with @option{-I} options (and the directory of the current file, if appropriate) are searched. @item -nostdinc++ @opindex nostdinc++ Do not search for header files in the C++-specific standard directories, but do still search the other standard directories. (This option is used when building the C++ library.) @item -include @var{file} @opindex include Process @var{file} as if @code{#include "file"} appeared as the first line of the primary source file. However, the first directory searched for @var{file} is the preprocessor's working directory @emph{instead of} the directory containing the main source file. If not found there, it is searched for in the remainder of the @code{#include "@dots{}"} search chain as normal. If multiple @option{-include} options are given, the files are included in the order they appear on the command line. @item -imacros @var{file} @opindex imacros Exactly like @option{-include}, except that any output produced by scanning @var{file} is thrown away. Macros it defines remain defined. This allows you to acquire all the macros from a header without also processing its declarations. All files specified by @option{-imacros} are processed before all files specified by @option{-include}. @item -idirafter @var{dir} @opindex idirafter Search @var{dir} for header files, but do it @emph{after} all directories specified with @option{-I} and the standard system directories have been exhausted. @var{dir} is treated as a system include directory. @item -iprefix @var{prefix} @opindex iprefix Specify @var{prefix} as the prefix for subsequent @option{-iwithprefix} options. If the prefix represents a directory, you should include the final @samp{/}. @item -iwithprefix @var{dir} @itemx -iwithprefixbefore @var{dir} @opindex iwithprefix @opindex iwithprefixbefore Append @var{dir} to the prefix specified previously with @option{-iprefix}, and add the resulting directory to the include search path. @option{-iwithprefixbefore} puts it in the same place @option{-I} would; @option{-iwithprefix} puts it where @option{-idirafter} would. @item -isysroot @var{dir} @opindex isysroot This option is like the @option{--sysroot} option, but applies only to header files. See the @option{--sysroot} option for more information. @item -imultilib @var{dir} @opindex imultilib Use @var{dir} as a subdirectory of the directory containing target-specific C++ headers. @item -isystem @var{dir} @opindex isystem Search @var{dir} for header files, after all directories specified by @option{-I} but before the standard system directories. Mark it as a system directory, so that it gets the same special treatment as is applied to the standard system directories. @ifset cppmanual @xref{System Headers}. @end ifset @item -iquote @var{dir} @opindex iquote Search @var{dir} only for header files requested with @code{@w{#include "@var{file}"}}; they are not searched for @code{@w{#include <@var{file}>}}, before all directories specified by @option{-I} and before the standard system directories. @ifset cppmanual @xref{Search Path}. @end ifset @item -fdollars-in-identifiers @opindex fdollars-in-identifiers @anchor{fdollars-in-identifiers} Accept @samp{$} in identifiers. @ifset cppmanual @xref{Identifier characters}. @end ifset @item -fextended-identifiers @opindex fextended-identifiers Accept universal character names in identifiers. This option is experimental; in a future version of GCC, it will be enabled by default for C99 and C++. @item -fpreprocessed @opindex fpreprocessed Indicate to the preprocessor that the input file has already been preprocessed. This suppresses things like macro expansion, trigraph conversion, escaped newline splicing, and processing of most directives. The preprocessor still recognizes and removes comments, so that you can pass a file preprocessed with @option{-C} to the compiler without problems. In this mode the integrated preprocessor is little more than a tokenizer for the front ends. @option{-fpreprocessed} is implicit if the input file has one of the extensions @samp{.i}, @samp{.ii} or @samp{.mi}. These are the extensions that GCC uses for preprocessed files created by @option{-save-temps}. @item -ftabstop=@var{width} @opindex ftabstop Set the distance between tab stops. This helps the preprocessor report correct column numbers in warnings or errors, even if tabs appear on the line. If the value is less than 1 or greater than 100, the option is ignored. The default is 8. @item -fexec-charset=@var{charset} @opindex fexec-charset @cindex character set, execution Set the execution character set, used for string and character constants. The default is UTF-8. @var{charset} can be any encoding supported by the system's @code{iconv} library routine. @item -fwide-exec-charset=@var{charset} @opindex fwide-exec-charset @cindex character set, wide execution Set the wide execution character set, used for wide string and character constants. The default is UTF-32 or UTF-16, whichever corresponds to the width of @code{wchar_t}. As with @option{-fexec-charset}, @var{charset} can be any encoding supported by the system's @code{iconv} library routine; however, you will have problems with encodings that do not fit exactly in @code{wchar_t}. @item -finput-charset=@var{charset} @opindex finput-charset @cindex character set, input Set the input character set, used for translation from the character set of the input file to the source character set used by GCC@. If the locale does not specify, or GCC cannot get this information from the locale, the default is UTF-8. This can be overridden by either the locale or this command line option. Currently the command line option takes precedence if there's a conflict. @var{charset} can be any encoding supported by the system's @code{iconv} library routine. @item -fworking-directory @opindex fworking-directory @opindex fno-working-directory Enable generation of linemarkers in the preprocessor output that will let the compiler know the current working directory at the time of preprocessing. When this option is enabled, the preprocessor will emit, after the initial linemarker, a second linemarker with the current working directory followed by two slashes. GCC will use this directory, when it's present in the preprocessed input, as the directory emitted as the current working directory in some debugging information formats. This option is implicitly enabled if debugging information is enabled, but this can be inhibited with the negated form @option{-fno-working-directory}. If the @option{-P} flag is present in the command line, this option has no effect, since no @code{#line} directives are emitted whatsoever. @item -fno-show-column @opindex fno-show-column Do not print column numbers in diagnostics. This may be necessary if diagnostics are being scanned by a program that does not understand the column numbers, such as @command{dejagnu}. @item -A @var{predicate}=@var{answer} @opindex A Make an assertion with the predicate @var{predicate} and answer @var{answer}. This form is preferred to the older form @option{-A @var{predicate}(@var{answer})}, which is still supported, because it does not use shell special characters. @ifset cppmanual @xref{Assertions}. @end ifset @item -A -@var{predicate}=@var{answer} Cancel an assertion with the predicate @var{predicate} and answer @var{answer}. @item -dCHARS @var{CHARS} is a sequence of one or more of the following characters, and must not be preceded by a space. Other characters are interpreted by the compiler proper, or reserved for future versions of GCC, and so are silently ignored. If you specify characters whose behavior conflicts, the result is undefined. @table @samp @item M @opindex dM Instead of the normal output, generate a list of @samp{#define} directives for all the macros defined during the execution of the preprocessor, including predefined macros. This gives you a way of finding out what is predefined in your version of the preprocessor. Assuming you have no file @file{foo.h}, the command @smallexample touch foo.h; cpp -dM foo.h @end smallexample @noindent will show all the predefined macros. @item D @opindex dD Like @samp{M} except in two respects: it does @emph{not} include the predefined macros, and it outputs @emph{both} the @samp{#define} directives and the result of preprocessing. Both kinds of output go to the standard output file. @item N @opindex dN Like @samp{D}, but emit only the macro names, not their expansions. @item I @opindex dI Output @samp{#include} directives in addition to the result of preprocessing. @end table @item -P @opindex P Inhibit generation of linemarkers in the output from the preprocessor. This might be useful when running the preprocessor on something that is not C code, and will be sent to a program which might be confused by the linemarkers. @ifset cppmanual @xref{Preprocessor Output}. @end ifset @item -C @opindex C Do not discard comments. All comments are passed through to the output file, except for comments in processed directives, which are deleted along with the directive. You should be prepared for side effects when using @option{-C}; it causes the preprocessor to treat comments as tokens in their own right. For example, comments appearing at the start of what would be a directive line have the effect of turning that line into an ordinary source line, since the first token on the line is no longer a @samp{#}. @item -CC Do not discard comments, including during macro expansion. This is like @option{-C}, except that comments contained within macros are also passed through to the output file where the macro is expanded. In addition to the side-effects of the @option{-C} option, the @option{-CC} option causes all C++-style comments inside a macro to be converted to C-style comments. This is to prevent later use of that macro from inadvertently commenting out the remainder of the source line. The @option{-CC} option is generally used to support lint comments. @item -traditional-cpp @opindex traditional-cpp Try to imitate the behavior of old-fashioned C preprocessors, as opposed to ISO C preprocessors. @ifset cppmanual @xref{Traditional Mode}. @end ifset @item -trigraphs @opindex trigraphs Process trigraph sequences. @ifset cppmanual @xref{Initial processing}. @end ifset @ifclear cppmanual These are three-character sequences, all starting with @samp{??}, that are defined by ISO C to stand for single characters. For example, @samp{??/} stands for @samp{\}, so @samp{'??/n'} is a character constant for a newline. By default, GCC ignores trigraphs, but in standard-conforming modes it converts them. See the @option{-std} and @option{-ansi} options. The nine trigraphs and their replacements are @smallexample Trigraph: ??( ??) ??< ??> ??= ??/ ??' ??! ??- Replacement: [ ] @{ @} # \ ^ | ~ @end smallexample @end ifclear @item -remap @opindex remap Enable special code to work around file systems which only permit very short file names, such as MS-DOS@. @itemx --help @itemx --target-help @opindex help @opindex target-help Print text describing all the command line options instead of preprocessing anything. @item -v @opindex v Verbose mode. Print out GNU CPP's version number at the beginning of execution, and report the final form of the include path. @item -H @opindex H Print the name of each header file used, in addition to other normal activities. Each name is indented to show how deep in the @samp{#include} stack it is. Precompiled header files are also printed, even if they are found to be invalid; an invalid precompiled header file is printed with @samp{...x} and a valid one with @samp{...!} . @item -version @itemx --version @opindex version Print out GNU CPP's version number. With one dash, proceed to preprocess as normal. With two dashes, exit immediately. @end table Index: head/contrib/gcc/doc/extend.texi =================================================================== --- head/contrib/gcc/doc/extend.texi (revision 220754) +++ head/contrib/gcc/doc/extend.texi (revision 220755) @@ -1,11123 +1,11120 @@ @c Copyright (C) 1988, 1989, 1992, 1993, 1994, 1996, 1998, 1999, 2000, @c 2001, 2002, 2003, 2004, 2005, 2006 Free Software Foundation, Inc. @c This is part of the GCC manual. @c For copying conditions, see the file gcc.texi. @node C Extensions @chapter Extensions to the C Language Family @cindex extensions, C language @cindex C language extensions @opindex pedantic GNU C provides several language features not found in ISO standard C@.

This allows you to use loops, switches, and local variables within an expression. Recall that a compound statement is a sequence of statements surrounded by braces; in this construct, parentheses go around the braces. For example: @smallexample (@{ int y = foo (); int z; if (y > 0) z = y; else z = - y; z; @}) @end smallexample @noindent is a valid (though slightly more complex than necessary) expression for the absolute value of @code{foo ()}. The last thing in the compound statement should be an expression followed by a semicolon; the value of this subexpression serves as the value of the entire construct. (If you use some other kind of statement last within the braces, the construct has type @code{void}, and thus effectively no value.) This feature is especially useful in making macro definitions ``safe'' (so that they evaluate each operand exactly once). For example, the ``maximum'' function is commonly defined as a macro in standard C as follows: @smallexample #define max(a,b) ((a) > (b) ? (a) : (b)) @end smallexample @noindent @cindex side effects, macro argument But this definition computes either @var{a} or @var{b} twice, with bad results if the operand has side effects. In GNU C, if you know the type of the operands (here taken as @code{int}), you can define the macro safely as follows: @smallexample #define maxint(a,b) \ (@{int _a = (a), _b = (b); _a > _b ? _a : _b; @}) @end smallexample Embedded statements are not allowed in constant expressions, such as the value of an enumeration constant, the width of a bit-field, or the initial value of a static variable. If you don't know the type of the operand, you can still do this, but you must use @code{typeof} (@pxref{Typeof}). In G++, the result value of a statement expression undergoes array and function pointer decay, and is returned by value to the enclosing expression. For instance, if @code{A} is a class, then @smallexample A a; (@{a;@}).Foo () @end smallexample @noindent will construct a temporary @code{A} object to hold the result of the statement expression, and that will be used to invoke @code{Foo}. Therefore the @code{this} pointer observed by @code{Foo} will not be the address of @code{a}. Any temporaries created within a statement within a statement expression will be destroyed at the statement's end. This makes statement expressions inside macros slightly different from function calls. In the latter case temporaries introduced during argument evaluation will be destroyed at the end of the statement that includes the function call. In the statement expression case they will be destroyed during the statement expression. For instance, @smallexample #define macro(a) (@{__typeof__(a) b = (a); b + 3; @}) template T function(T a) @{ T b = a; return b + 3; @} void foo () @{ macro (X ()); function (X ()); @} @end smallexample @noindent will have different places where temporaries are destroyed. For the @code{macro} case, the temporary @code{X} will be destroyed just after the initialization of @code{b}. In the @code{function} case that temporary will be destroyed when the function returns. These considerations mean that it is probably a bad idea to use statement-expressions of this form in header files that are designed to work with C++. (Note that some versions of the GNU C Library contained header files using statement-expression that lead to precisely this bug.) Jumping into a statement expression with @code{goto} or using a @code{switch} statement outside the statement expression with a @code{case} or @code{default} label inside the statement expression is not permitted. Jumping into a statement expression with a computed @code{goto} (@pxref{Labels as Values}) yields undefined behavior. Jumping out of a statement expression is permitted, but if the statement expression is part of a larger expression then it is unspecified which other subexpressions of that expression have been evaluated except where the language definition requires certain subexpressions to be evaluated before or after the statement expression. In any case, as with a function call the evaluation of a statement expression is not interleaved with the evaluation of other parts of the containing expression. For example, @smallexample foo (), ((@{ bar1 (); goto a; 0; @}) + bar2 ()), baz(); @end smallexample @noindent will call @code{foo} and @code{bar1} and will not call @code{baz} but may or may not call @code{bar2}. If @code{bar2} is called, it will be called after @code{foo} and before @code{bar1} @node Local Labels @section Locally Declared Labels @cindex local labels @cindex macros, local labels GCC allows you to declare @dfn{local labels} in any nested block scope. A local label is just like an ordinary label, but you can only reference it (with a @code{goto} statement, or by taking its address) within the block in which it was declared. A local label declaration looks like this: @smallexample __label__ @var{label}; @end smallexample @noindent or @smallexample __label__ @var{label1}, @var{label2}, /* @r{@dots{}} */; @end smallexample Local label declarations must come at the beginning of the block, before any ordinary declarations or statements. The label declaration defines the label @emph{name}, but does not define the label itself. You must do this in the usual way, with @code{@var{label}:}, within the statements of the statement expression. The local label feature is useful for complex macros. If a macro contains nested loops, a @code{goto} can be useful for breaking out of them. However, an ordinary label whose scope is the whole function cannot be used: if the macro can be expanded several times in one function, the label will be multiply defined in that function. A local label avoids this problem. For example: @smallexample #define SEARCH(value, array, target) \ do @{ \ __label__ found; \ typeof (target) _SEARCH_target = (target); \ typeof (*(array)) *_SEARCH_array = (array); \ int i, j; \ int value; \ for (i = 0; i < max; i++) \ for (j = 0; j < max; j++) \ if (_SEARCH_array[i][j] == _SEARCH_target) \ @{ (value) = i; goto found; @} \ (value) = -1; \ found:; \ @} while (0) @end smallexample This could also be written using a statement-expression: @smallexample #define SEARCH(array, target) \ (@{ \ __label__ found; \ typeof (target) _SEARCH_target = (target); \ typeof (*(array)) *_SEARCH_array = (array); \ int i, j; \ int value; \ for (i = 0; i < max; i++) \ for (j = 0; j < max; j++) \ if (_SEARCH_array[i][j] == _SEARCH_target) \ @{ value = i; goto found; @} \ value = -1; \ found: \ value; \ @}) @end smallexample Local label declarations also make the labels they declare visible to nested functions, if there are any. @xref{Nested Functions}, for details. @node Labels as Values @section Labels as Values @cindex labels as values @cindex computed gotos @cindex goto with computed label @cindex address of a label You can get the address of a label defined in the current function (or a containing function) with the unary operator @samp{&&}. The value has type @code{void *}. This value is a constant and can be used wherever a constant of that type is valid. For example: @smallexample void *ptr; /* @r{@dots{}} */ ptr = &&foo; @end smallexample To use these values, you need to be able to jump to one. This is done with the computed goto statement@footnote{The analogous feature in Fortran is called an assigned goto, but that name seems inappropriate in C, where one can do more than simply store label addresses in label variables.}, @code{goto *@var{exp};}. For example, @smallexample goto *ptr; @end smallexample @noindent Any expression of type @code{void *} is allowed. One way of using these constants is in initializing a static array that will serve as a jump table: @smallexample static void *array[] = @{ &&foo, &&bar, &&hack @}; @end smallexample Then you can select a label with indexing, like this: @smallexample goto *array[i]; @end smallexample @noindent Note that this does not check whether the subscript is in bounds---array indexing in C never does that. Such an array of label values serves a purpose much like that of the @code{switch} statement. The @code{switch} statement is cleaner, so use that rather than an array unless the problem does not fit a @code{switch} statement very well. Another use of label values is in an interpreter for threaded code. The labels within the interpreter function can be stored in the threaded code for super-fast dispatching. You may not use this mechanism to jump to code in a different function. If you do that, totally unpredictable things will happen. The best way to avoid this is to store the label address only in automatic variables and never pass it as an argument. An alternate way to write the above example is @smallexample static const int array[] = @{ &&foo - &&foo, &&bar - &&foo, &&hack - &&foo @}; goto *(&&foo + array[i]); @end smallexample @noindent This is more friendly to code living in shared libraries, as it reduces the number of dynamic relocations that are needed, and by consequence, allows the data to be read-only. @node Nested Functions @section Nested Functions @cindex nested functions @cindex downward funargs @cindex thunks A @dfn{nested function} is a function defined inside another function. (Nested functions are not supported for GNU C++.) The nested function's name is local to the block where it is defined. For example, here we define a nested function named @code{square}, and call it twice: @smallexample @group foo (double a, double b) @{ double square (double z) @{ return z * z; @} return square (a) + square (b); @} @end group @end smallexample The nested function can access all the variables of the containing function that are visible at the point of its definition. This is called @dfn{lexical scoping}. For example, here we show a nested function which uses an inherited variable named @code{offset}: @smallexample @group bar (int *array, int offset, int size) @{ int access (int *array, int index) @{ return array[index + offset]; @} int i; /* @r{@dots{}} */ for (i = 0; i < size; i++) /* @r{@dots{}} */ access (array, i) /* @r{@dots{}} */ @} @end group @end smallexample Nested function definitions are permitted within functions in the places where variable definitions are allowed; that is, in any block, mixed with the other declarations and statements in the block. It is possible to call the nested function from outside the scope of its name by storing its address or passing the address to another function: @smallexample hack (int *array, int size) @{ void store (int index, int value) @{ array[index] = value; @} intermediate (store, size); @} @end smallexample Here, the function @code{intermediate} receives the address of @code{store} as an argument. If @code{intermediate} calls @code{store}, the arguments given to @code{store} are used to store into @code{array}. But this technique works only so long as the containing function (@code{hack}, in this example) does not exit. If you try to call the nested function through its address after the containing function has exited, all hell will break loose. If you try to call it after a containing scope level has exited, and if it refers to some of the variables that are no longer in scope, you may be lucky, but it's not wise to take the risk. If, however, the nested function does not refer to anything that has gone out of scope, you should be safe. GCC implements taking the address of a nested function using a technique called @dfn{trampolines}. A paper describing them is available as @noindent @uref{http://people.debian.org/~aaronl/Usenix88-lexic.pdf}. A nested function can jump to a label inherited from a containing function, provided the label was explicitly declared in the containing function (@pxref{Local Labels}). Such a jump returns instantly to the containing function, exiting the nested function which did the @code{goto} and any intermediate functions as well. Here is an example: @smallexample @group bar (int *array, int offset, int size) @{ __label__ failure; int access (int *array, int index) @{ if (index > size) goto failure; return array[index + offset]; @} int i; /* @r{@dots{}} */ for (i = 0; i < size; i++) /* @r{@dots{}} */ access (array, i) /* @r{@dots{}} */ /* @r{@dots{}} */ return 0; /* @r{Control comes here from @code{access} if it detects an error.} */ failure: return -1; @} @end group @end smallexample A nested function always has no linkage. Declaring one with @code{extern} or @code{static} is erroneous. If you need to declare the nested function before its definition, use @code{auto} (which is otherwise meaningless for function declarations). @smallexample bar (int *array, int offset, int size) @{ __label__ failure; auto int access (int *, int); /* @r{@dots{}} */ int access (int *array, int index) @{ if (index > size) goto failure; return array[index + offset]; @} /* @r{@dots{}} */ @} @end smallexample @node Constructing Calls @section Constructing Function Calls @cindex constructing calls @cindex forwarding calls Using the built-in functions described below, you can record the arguments a function received, and call another function with the same arguments, without knowing the number or types of the arguments. You can also record the return value of that function call, and later return that value, without knowing what data type the function tried to return (as long as your caller expects that data type). However, these built-in functions may interact badly with some sophisticated features or other extensions of the language. It is, therefore, not recommended to use them outside very simple functions acting as mere forwarders for their arguments. @deftypefn {Built-in Function} {void *} __builtin_apply_args () This built-in function returns a pointer to data describing how to perform a call with the same arguments as were passed to the current function. The function saves the arg pointer register, structure value address, and all registers that might be used to pass arguments to a function into a block of memory allocated on the stack. Then it returns the address of that block. @end deftypefn @deftypefn {Built-in Function} {void *} __builtin_apply (void (*@var{function})(), void *@var{arguments}, size_t @var{size}) This built-in function invokes @var{function} with a copy of the parameters described by @var{arguments} and @var{size}. The value of @var{arguments} should be the value returned by @code{__builtin_apply_args}. The argument @var{size} specifies the size of the stack argument data, in bytes. This function returns a pointer to data describing how to return whatever value was returned by @var{function}. The data is saved in a block of memory allocated on the stack. It is not always simple to compute the proper value for @var{size}. The value is used by @code{__builtin_apply} to compute the amount of data that should be pushed on the stack and copied from the incoming argument area. @end deftypefn @deftypefn {Built-in Function} {void} __builtin_return (void *@var{result}) This built-in function returns the value described by @var{result} from the containing function. You should specify, for @var{result}, a value returned by @code{__builtin_apply}. @end deftypefn @node Typeof @section Referring to a Type with @code{typeof} @findex typeof @findex sizeof @cindex macros, types of arguments Another way to refer to the type of an expression is with @code{typeof}. The syntax of using of this keyword looks like @code{sizeof}, but the construct acts semantically like a type name defined with @code{typedef}. There are two ways of writing the argument to @code{typeof}: with an expression or with a type. Here is an example with an expression: @smallexample typeof (x[0](1)) @end smallexample @noindent This assumes that @code{x} is an array of pointers to functions; the type described is that of the values of the functions. Here is an example with a typename as the argument: @smallexample typeof (int *) @end smallexample @noindent Here the type described is that of pointers to @code{int}. If you are writing a header file that must work when included in ISO C programs, write @code{__typeof__} instead of @code{typeof}. @xref{Alternate Keywords}. A @code{typeof}-construct can be used anywhere a typedef name could be used. For example, you can use it in a declaration, in a cast, or inside of @code{sizeof} or @code{typeof}. @code{typeof} is often useful in conjunction with the statements-within-expressions feature. Here is how the two together can be used to define a safe ``maximum'' macro that operates on any arithmetic type and evaluates each of its arguments exactly once: @smallexample #define max(a,b) \ (@{ typeof (a) _a = (a); \ typeof (b) _b = (b); \ _a > _b ? _a : _b; @}) @end smallexample @cindex underscores in variables in macros @cindex @samp{_} in variables in macros @cindex local variables in macros @cindex variables, local, in macros @cindex macros, local variables in The reason for using names that start with underscores for the local variables is to avoid conflicts with variable names that occur within the expressions that are substituted for @code{a} and @code{b}. Eventually we hope to design a new form of declaration syntax that allows you to declare variables whose scopes start only after their initializers; this will be a more reliable way to prevent such conflicts. @noindent Some more examples of the use of @code{typeof}: @itemize @bullet @item This declares @code{y} with the type of what @code{x} points to. @smallexample typeof (*x) y; @end smallexample @item This declares @code{y} as an array of such values. @smallexample typeof (*x) y[4]; @end smallexample @item This declares @code{y} as an array of pointers to characters: @smallexample typeof (typeof (char *)[4]) y; @end smallexample @noindent It is equivalent to the following traditional C declaration: @smallexample char *y[4]; @end smallexample To see the meaning of the declaration using @code{typeof}, and why it might be a useful way to write, rewrite it with these macros: @smallexample #define pointer(T) typeof(T *) #define array(T, N) typeof(T [N]) @end smallexample @noindent Now the declaration can be rewritten this way: @smallexample array (pointer (char), 4) y; @end smallexample @noindent Thus, @code{array (pointer (char), 4)} is the type of arrays of 4 pointers to @code{char}. @end itemize @emph{Compatibility Note:} In addition to @code{typeof}, GCC 2 supported a more limited extension which permitted one to write @smallexample typedef @var{T} = @var{expr}; @end smallexample @noindent with the effect of declaring @var{T} to have the type of the expression @var{expr}. This extension does not work with GCC 3 (versions between 3.0 and 3.2 will crash; 3.2.1 and later give an error). Code which relies on it should be rewritten to use @code{typeof}: @smallexample typedef typeof(@var{expr}) @var{T}; @end smallexample @noindent This will work with all versions of GCC@. @node Conditionals @section Conditionals with Omitted Operands @cindex conditional expressions, extensions @cindex omitted middle-operands @cindex middle-operands, omitted @cindex extensions, @code{?:} @cindex @code{?:} extensions The middle operand in a conditional expression may be omitted. Then if the first operand is nonzero, its value is the value of the conditional expression. Therefore, the expression @smallexample x ? : y @end smallexample @noindent has the value of @code{x} if that is nonzero; otherwise, the value of @code{y}. This example is perfectly equivalent to @smallexample x ? x : y @end smallexample @cindex side effect in ?: @cindex ?: side effect @noindent In this simple case, the ability to omit the middle operand is not especially useful. When it becomes useful is when the first operand does, or may (if it is a macro argument), contain a side effect. Then repeating the operand in the middle would perform the side effect twice. Omitting the middle operand uses the value already computed without the undesirable effects of recomputing it. @node Long Long @section Double-Word Integers @cindex @code{long long} data types @cindex double-word arithmetic @cindex multiprecision arithmetic @cindex @code{LL} integer suffix @cindex @code{ULL} integer suffix ISO C99 supports data types for integers that are at least 64 bits wide, and as an extension GCC supports them in C89 mode and in C++. Simply write @code{long long int} for a signed integer, or @code{unsigned long long int} for an unsigned integer. To make an integer constant of type @code{long long int}, add the suffix @samp{LL} to the integer. To make an integer constant of type @code{unsigned long long int}, add the suffix @samp{ULL} to the integer. You can use these types in arithmetic like any other integer types. Addition, subtraction, and bitwise boolean operations on these types are open-coded on all types of machines. Multiplication is open-coded if the machine supports fullword-to-doubleword a widening multiply instruction. Division and shifts are open-coded only on machines that provide special support. The operations that are not open-coded use special library routines that come with GCC@. There may be pitfalls when you use @code{long long} types for function arguments, unless you declare function prototypes. If a function expects type @code{int} for its argument, and you pass a value of type @code{long long int}, confusion will result because the caller and the subroutine will disagree about the number of bytes for the argument. Likewise, if the function expects @code{long long int} and you pass @code{int}. The best way to avoid such problems is to use prototypes. @node Complex @section Complex Numbers @cindex complex numbers @cindex @code{_Complex} keyword @cindex @code{__complex__} keyword ISO C99 supports complex floating data types, and as an extension GCC supports them in C89 mode and in C++, and supports complex integer data types which are not part of ISO C99. You can declare complex types using the keyword @code{_Complex}. As an extension, the older GNU keyword @code{__complex__} is also supported. For example, @samp{_Complex double x;} declares @code{x} as a variable whose real part and imaginary part are both of type @code{double}. @samp{_Complex short int y;} declares @code{y} to have real and imaginary parts of type @code{short int}; this is not likely to be useful, but it shows that the set of complex types is complete. To write a constant with a complex data type, use the suffix @samp{i} or @samp{j} (either one; they are equivalent). For example, @code{2.5fi} has type @code{_Complex float} and @code{3i} has type @code{_Complex int}. Such a constant always has a pure imaginary value, but you can form any complex value you like by adding one to a real constant. This is a GNU extension; if you have an ISO C99 conforming C library (such as GNU libc), and want to construct complex constants of floating type, you should include @code{} and use the macros @code{I} or @code{_Complex_I} instead. @cindex @code{__real__} keyword @cindex @code{__imag__} keyword To extract the real part of a complex-valued expression @var{exp}, write @code{__real__ @var{exp}}. Likewise, use @code{__imag__} to extract the imaginary part. This is a GNU extension; for values of floating type, you should use the ISO C99 functions @code{crealf}, @code{creal}, @code{creall}, @code{cimagf}, @code{cimag} and @code{cimagl}, declared in @code{} and also provided as built-in functions by GCC@. @cindex complex conjugation The operator @samp{~} performs complex conjugation when used on a value with a complex type. This is a GNU extension; for values of floating type, you should use the ISO C99 functions @code{conjf}, @code{conj} and @code{conjl}, declared in @code{} and also provided as built-in functions by GCC@. GCC can allocate complex automatic variables in a noncontiguous fashion; it's even possible for the real part to be in a register while the imaginary part is on the stack (or vice-versa). Only the DWARF2 debug info format can represent this, so use of DWARF2 is recommended. If you are using the stabs debug info format, GCC describes a noncontiguous complex variable as if it were two separate variables of noncomplex type. If the variable's actual name is @code{foo}, the two fictitious variables are named @code{foo$real} and @code{foo$imag}. You can examine and set these two fictitious variables with your debugger. @node Decimal Float @section Decimal Floating Types @cindex decimal floating types @cindex @code{_Decimal32} data type @cindex @code{_Decimal64} data type @cindex @code{_Decimal128} data type @cindex @code{df} integer suffix @cindex @code{dd} integer suffix @cindex @code{dl} integer suffix @cindex @code{DF} integer suffix @cindex @code{DD} integer suffix @cindex @code{DL} integer suffix As an extension, the GNU C compiler supports decimal floating types as defined in the N1176 draft of ISO/IEC WDTR24732. Support for decimal floating types in GCC will evolve as the draft technical report changes. Calling conventions for any target might also change. Not all targets support decimal floating types. The decimal floating types are @code{_Decimal32}, @code{_Decimal64}, and @code{_Decimal128}. They use a radix of ten, unlike the floating types @code{float}, @code{double}, and @code{long double} whose radix is not specified by the C standard but is usually two. Support for decimal floating types includes the arithmetic operators add, subtract, multiply, divide; unary arithmetic operators; relational operators; equality operators; and conversions to and from integer and other floating types. Use a suffix @samp{df} or @samp{DF} in a literal constant of type @code{_Decimal32}, @samp{dd} or @samp{DD} for @code{_Decimal64}, and @samp{dl} or @samp{DL} for @code{_Decimal128}. GCC support of decimal float as specified by the draft technical report is incomplete: @itemize @bullet @item Translation time data type (TTDT) is not supported. @item Characteristics of decimal floating types are defined in header file @file{decfloat.h} rather than @file{float.h}. @item When the value of a decimal floating type cannot be represented in the integer type to which it is being converted, the result is undefined rather than the result value specified by the draft technical report. @end itemize Types @code{_Decimal32}, @code{_Decimal64}, and @code{_Decimal128} are supported by the DWARF2 debug information format. @node Hex Floats @section Hex Floats @cindex hex floats ISO C99 supports floating-point numbers written not only in the usual decimal notation, such as @code{1.55e1}, but also numbers such as @code{0x1.fp3} written in hexadecimal format. As a GNU extension, GCC supports this in C89 mode (except in some cases when strictly conforming) and in C++. In that format the @samp{0x} hex introducer and the @samp{p} or @samp{P} exponent field are mandatory. The exponent is a decimal number that indicates the power of 2 by which the significant part will be multiplied. Thus @samp{0x1.f} is @tex $1 {15\over16}$, @end tex @ifnottex 1 15/16, @end ifnottex @samp{p3} multiplies it by 8, and the value of @code{0x1.fp3} is the same as @code{1.55e1}. Unlike for floating-point numbers in the decimal notation the exponent is always required in the hexadecimal notation. Otherwise the compiler would not be able to resolve the ambiguity of, e.g., @code{0x1.f}. This could mean @code{1.0f} or @code{1.9375} since @samp{f} is also the extension for floating-point constants of type @code{float}. @node Zero Length @section Arrays of Length Zero @cindex arrays of length zero @cindex zero-length arrays @cindex length-zero arrays @cindex flexible array members Zero-length arrays are allowed in GNU C@. They are very useful as the last element of a structure which is really a header for a variable-length object: @smallexample struct line @{ int length; char contents[0]; @}; struct line *thisline = (struct line *) malloc (sizeof (struct line) + this_length); thisline->length = this_length; @end smallexample In ISO C90, you would have to give @code{contents} a length of 1, which means either you waste space or complicate the argument to @code{malloc}. In ISO C99, you would use a @dfn{flexible array member}, which is slightly different in syntax and semantics: @itemize @bullet @item Flexible array members are written as @code{contents[]} without the @code{0}. @item Flexible array members have incomplete type, and so the @code{sizeof} operator may not be applied. As a quirk of the original implementation of zero-length arrays, @code{sizeof} evaluates to zero. @item Flexible array members may only appear as the last member of a @code{struct} that is otherwise non-empty. @item A structure containing a flexible array member, or a union containing such a structure (possibly recursively), may not be a member of a structure or an element of an array. (However, these uses are permitted by GCC as extensions.) @end itemize GCC versions before 3.0 allowed zero-length arrays to be statically initialized, as if they were flexible arrays. In addition to those cases that were useful, it also allowed initializations in situations that would corrupt later data. Non-empty initialization of zero-length arrays is now treated like any case where there are more initializer elements than the array holds, in that a suitable warning about "excess elements in array" is given, and the excess elements (all of them, in this case) are ignored. Instead GCC allows static initialization of flexible array members. This is equivalent to defining a new structure containing the original structure followed by an array of sufficient size to contain the data. I.e.@: in the following, @code{f1} is constructed as if it were declared like @code{f2}. @smallexample struct f1 @{ int x; int y[]; @} f1 = @{ 1, @{ 2, 3, 4 @} @}; struct f2 @{ struct f1 f1; int data[3]; @} f2 = @{ @{ 1 @}, @{ 2, 3, 4 @} @}; @end smallexample @noindent The convenience of this extension is that @code{f1} has the desired type, eliminating the need to consistently refer to @code{f2.f1}. This has symmetry with normal static arrays, in that an array of unknown size is also written with @code{[]}. Of course, this extension only makes sense if the extra data comes at the end of a top-level object, as otherwise we would be overwriting data at subsequent offsets. To avoid undue complication and confusion with initialization of deeply nested arrays, we simply disallow any non-empty initialization except when the structure is the top-level object. For example: @smallexample struct foo @{ int x; int y[]; @}; struct bar @{ struct foo z; @}; struct foo a = @{ 1, @{ 2, 3, 4 @} @}; // @r{Valid.} struct bar b = @{ @{ 1, @{ 2, 3, 4 @} @} @}; // @r{Invalid.} struct bar c = @{ @{ 1, @{ @} @} @}; // @r{Valid.} struct foo d[1] = @{ @{ 1 @{ 2, 3, 4 @} @} @}; // @r{Invalid.} @end smallexample @node Empty Structures @section Structures With No Members @cindex empty structures @cindex zero-size structures GCC permits a C structure to have no members: @smallexample struct empty @{ @}; @end smallexample The structure will have size zero. In C++, empty structures are part of the language. G++ treats empty structures as if they had a single member of type @code{char}. @node Variable Length @section Arrays of Variable Length @cindex variable-length arrays @cindex arrays of variable length @cindex VLAs Variable-length automatic arrays are allowed in ISO C99, and as an extension GCC accepts them in C89 mode and in C++. (However, GCC's implementation of variable-length arrays does not yet conform in detail to the ISO C99 standard.) These arrays are declared like any other automatic arrays, but with a length that is not a constant expression. The storage is allocated at the point of declaration and deallocated when the brace-level is exited. For example: @smallexample FILE * concat_fopen (char *s1, char *s2, char *mode) @{ char str[strlen (s1) + strlen (s2) + 1]; strcpy (str, s1); strcat (str, s2); return fopen (str, mode); @} @end smallexample @cindex scope of a variable length array @cindex variable-length array scope @cindex deallocating variable length arrays Jumping or breaking out of the scope of the array name deallocates the storage. Jumping into the scope is not allowed; you get an error message for it. @cindex @code{alloca} vs variable-length arrays You can use the function @code{alloca} to get an effect much like variable-length arrays. The function @code{alloca} is available in many other C implementations (but not in all). On the other hand, variable-length arrays are more elegant. There are other differences between these two methods. Space allocated with @code{alloca} exists until the containing @emph{function} returns. The space for a variable-length array is deallocated as soon as the array name's scope ends. (If you use both variable-length arrays and @code{alloca} in the same function, deallocation of a variable-length array will also deallocate anything more recently allocated with @code{alloca}.) You can also use variable-length arrays as arguments to functions: @smallexample struct entry tester (int len, char data[len][len]) @{ /* @r{@dots{}} */ @} @end smallexample The length of an array is computed once when the storage is allocated and is remembered for the scope of the array in case you access it with @code{sizeof}. If you want to pass the array first and the length afterward, you can use a forward declaration in the parameter list---another GNU extension. @smallexample struct entry tester (int len; char data[len][len], int len) @{ /* @r{@dots{}} */ @} @end smallexample @cindex parameter forward declaration The @samp{int len} before the semicolon is a @dfn{parameter forward declaration}, and it serves the purpose of making the name @code{len} known when the declaration of @code{data} is parsed. You can write any number of such parameter forward declarations in the parameter list. They can be separated by commas or semicolons, but the last one must end with a semicolon, which is followed by the ``real'' parameter declarations. Each forward declaration must match a ``real'' declaration in parameter name and data type. ISO C99 does not support parameter forward declarations. @node Variadic Macros @section Macros with a Variable Number of Arguments. @cindex variable number of arguments @cindex macro with variable arguments @cindex rest argument (in macro) @cindex variadic macros In the ISO C standard of 1999, a macro can be declared to accept a variable number of arguments much as a function can. The syntax for defining the macro is similar to that of a function. Here is an example: @smallexample #define debug(format, ...) fprintf (stderr, format, __VA_ARGS__) @end smallexample Here @samp{@dots{}} is a @dfn{variable argument}. In the invocation of such a macro, it represents the zero or more tokens until the closing parenthesis that ends the invocation, including any commas. This set of tokens replaces the identifier @code{__VA_ARGS__} in the macro body wherever it appears. See the CPP manual for more information. GCC has long supported variadic macros, and used a different syntax that allowed you to give a name to the variable arguments just like any other argument. Here is an example: @smallexample #define debug(format, args...) fprintf (stderr, format, args) @end smallexample This is in all ways equivalent to the ISO C example above, but arguably more readable and descriptive. GNU CPP has two further variadic macro extensions, and permits them to be used with either of the above forms of macro definition. In standard C, you are not allowed to leave the variable argument out entirely; but you are allowed to pass an empty argument. For example, this invocation is invalid in ISO C, because there is no comma after the string: @smallexample debug ("A message") @end smallexample GNU CPP permits you to completely omit the variable arguments in this way. In the above examples, the compiler would complain, though since the expansion of the macro still has the extra comma after the format string. To help solve this problem, CPP behaves specially for variable arguments used with the token paste operator, @samp{##}. If instead you write @smallexample #define debug(format, ...) fprintf (stderr, format, ## __VA_ARGS__) @end smallexample and if the variable arguments are omitted or empty, the @samp{##} operator causes the preprocessor to remove the comma before it. If you do provide some variable arguments in your macro invocation, GNU CPP does not complain about the paste operation and instead places the variable arguments after the comma. Just like any other pasted macro argument, these arguments are not macro expanded. @node Escaped Newlines @section Slightly Looser Rules for Escaped Newlines @cindex escaped newlines @cindex newlines (escaped) Recently, the preprocessor has relaxed its treatment of escaped newlines. Previously, the newline had to immediately follow a backslash. The current implementation allows whitespace in the form of spaces, horizontal and vertical tabs, and form feeds between the backslash and the subsequent newline. The preprocessor issues a warning, but treats it as a valid escaped newline and combines the two lines to form a single logical line. This works within comments and tokens, as well as between tokens. Comments are @emph{not} treated as whitespace for the purposes of this relaxation, since they have not yet been replaced with spaces. @node Subscripting @section Non-Lvalue Arrays May Have Subscripts @cindex subscripting @cindex arrays, non-lvalue @cindex subscripting and function values In ISO C99, arrays that are not lvalues still decay to pointers, and may be subscripted, although they may not be modified or used after the next sequence point and the unary @samp{&} operator may not be applied to them. As an extension, GCC allows such arrays to be subscripted in C89 mode, though otherwise they do not decay to pointers outside C99 mode. For example, this is valid in GNU C though not valid in C89: @smallexample @group struct foo @{int a[4];@}; struct foo f(); bar (int index) @{ return f().a[index]; @} @end group @end smallexample @node Pointer Arith @section Arithmetic on @code{void}- and Function-Pointers @cindex void pointers, arithmetic @cindex void, size of pointer to @cindex function pointers, arithmetic @cindex function, size of pointer to In GNU C, addition and subtraction operations are supported on pointers to @code{void} and on pointers to functions. This is done by treating the size of a @code{void} or of a function as 1. A consequence of this is that @code{sizeof} is also allowed on @code{void} and on function types, and returns 1. @opindex Wpointer-arith The option @option{-Wpointer-arith} requests a warning if these extensions are used. @node Initializers @section Non-Constant Initializers @cindex initializers, non-constant @cindex non-constant initializers As in standard C++ and ISO C99, the elements of an aggregate initializer for an automatic variable are not required to be constant expressions in GNU C@. Here is an example of an initializer with run-time varying elements: @smallexample foo (float f, float g) @{ float beat_freqs[2] = @{ f-g, f+g @}; /* @r{@dots{}} */ @} @end smallexample @node Compound Literals @section Compound Literals @cindex constructor expressions @cindex initializations in expressions @cindex structures, constructor expression @cindex expressions, constructor @cindex compound literals @c The GNU C name for what C99 calls compound literals was "constructor expressions". ISO C99 supports compound literals. A compound literal looks like a cast containing an initializer. Its value is an object of the type specified in the cast, containing the elements specified in the initializer; it is an lvalue. As an extension, GCC supports compound literals in C89 mode and in C++. Usually, the specified type is a structure. Assume that @code{struct foo} and @code{structure} are declared as shown: @smallexample struct foo @{int a; char b[2];@} structure; @end smallexample @noindent Here is an example of constructing a @code{struct foo} with a compound literal: @smallexample structure = ((struct foo) @{x + y, 'a', 0@}); @end smallexample @noindent This is equivalent to writing the following: @smallexample @{ struct foo temp = @{x + y, 'a', 0@}; structure = temp; @} @end smallexample You can also construct an array. If all the elements of the compound literal are (made up of) simple constant expressions, suitable for use in initializers of objects of static storage duration, then the compound literal can be coerced to a pointer to its first element and used in such an initializer, as shown here: @smallexample char **foo = (char *[]) @{ "x", "y", "z" @}; @end smallexample Compound literals for scalar types and union types are is also allowed, but then the compound literal is equivalent to a cast. As a GNU extension, GCC allows initialization of objects with static storage duration by compound literals (which is not possible in ISO C99, because the initializer is not a constant). It is handled as if the object was initialized only with the bracket enclosed list if the types of the compound literal and the object match. The initializer list of the compound literal must be constant. If the object being initialized has array type of unknown size, the size is determined by compound literal size. @smallexample static struct foo x = (struct foo) @{1, 'a', 'b'@}; static int y[] = (int []) @{1, 2, 3@}; static int z[] = (int [3]) @{1@}; @end smallexample @noindent The above lines are equivalent to the following: @smallexample static struct foo x = @{1, 'a', 'b'@}; static int y[] = @{1, 2, 3@}; static int z[] = @{1, 0, 0@}; @end smallexample @node Designated Inits @section Designated Initializers @cindex initializers with labeled elements @cindex labeled elements in initializers @cindex case labels in initializers @cindex designated initializers Standard C89 requires the elements of an initializer to appear in a fixed order, the same as the order of the elements in the array or structure being initialized. In ISO C99 you can give the elements in any order, specifying the array indices or structure field names they apply to, and GNU C allows this as an extension in C89 mode as well. This extension is not implemented in GNU C++. To specify an array index, write @samp{[@var{index}] =} before the element value. For example, @smallexample int a[6] = @{ [4] = 29, [2] = 15 @}; @end smallexample @noindent is equivalent to @smallexample int a[6] = @{ 0, 0, 15, 0, 29, 0 @}; @end smallexample @noindent The index values must be constant expressions, even if the array being initialized is automatic. An alternative syntax for this which has been obsolete since GCC 2.5 but GCC still accepts is to write @samp{[@var{index}]} before the element value, with no @samp{=}. To initialize a range of elements to the same value, write @samp{[@var{first} ... @var{last}] = @var{value}}. This is a GNU extension. For example, @smallexample int widths[] = @{ [0 ... 9] = 1, [10 ... 99] = 2, [100] = 3 @}; @end smallexample @noindent If the value in it has side-effects, the side-effects will happen only once, not for each initialized field by the range initializer. @noindent Note that the length of the array is the highest value specified plus one. In a structure initializer, specify the name of a field to initialize with @samp{.@var{fieldname} =} before the element value. For example, given the following structure, @smallexample struct point @{ int x, y; @}; @end smallexample @noindent the following initialization @smallexample struct point p = @{ .y = yvalue, .x = xvalue @}; @end smallexample @noindent is equivalent to @smallexample struct point p = @{ xvalue, yvalue @}; @end smallexample Another syntax which has the same meaning, obsolete since GCC 2.5, is @samp{@var{fieldname}:}, as shown here: @smallexample struct point p = @{ y: yvalue, x: xvalue @}; @end smallexample @cindex designators The @samp{[@var{index}]} or @samp{.@var{fieldname}} is known as a @dfn{designator}. You can also use a designator (or the obsolete colon syntax) when initializing a union, to specify which element of the union should be used. For example, @smallexample union foo @{ int i; double d; @}; union foo f = @{ .d = 4 @}; @end smallexample @noindent will convert 4 to a @code{double} to store it in the union using the second element. By contrast, casting 4 to type @code{union foo} would store it into the union as the integer @code{i}, since it is an integer. (@xref{Cast to Union}.) You can combine this technique of naming elements with ordinary C initialization of successive elements. Each initializer element that does not have a designator applies to the next consecutive element of the array or structure. For example, @smallexample int a[6] = @{ [1] = v1, v2, [4] = v4 @}; @end smallexample @noindent is equivalent to @smallexample int a[6] = @{ 0, v1, v2, 0, v4, 0 @}; @end smallexample Labeling the elements of an array initializer is especially useful when the indices are characters or belong to an @code{enum} type. For example: @smallexample int whitespace[256] = @{ [' '] = 1, ['\t'] = 1, ['\h'] = 1, ['\f'] = 1, ['\n'] = 1, ['\r'] = 1 @}; @end smallexample @cindex designator lists You can also write a series of @samp{.@var{fieldname}} and @samp{[@var{index}]} designators before an @samp{=} to specify a nested subobject to initialize; the list is taken relative to the subobject corresponding to the closest surrounding brace pair. For example, with the @samp{struct point} declaration above: @smallexample struct point ptarray[10] = @{ [2].y = yv2, [2].x = xv2, [0].x = xv0 @}; @end smallexample @noindent If the same field is initialized multiple times, it will have value from the last initialization. If any such overridden initialization has side-effect, it is unspecified whether the side-effect happens or not. Currently, GCC will discard them and issue a warning. @node Case Ranges @section Case Ranges @cindex case ranges @cindex ranges in case statements You can specify a range of consecutive values in a single @code{case} label, like this: @smallexample case @var{low} ... @var{high}: @end smallexample @noindent This has the same effect as the proper number of individual @code{case} labels, one for each integer value from @var{low} to @var{high}, inclusive. This feature is especially useful for ranges of ASCII character codes: @smallexample case 'A' ... 'Z': @end smallexample @strong{Be careful:} Write spaces around the @code{...}, for otherwise it may be parsed wrong when you use it with integer values. For example, write this: @smallexample case 1 ... 5: @end smallexample @noindent rather than this: @smallexample case 1...5: @end smallexample @node Cast to Union @section Cast to a Union Type @cindex cast to a union @cindex union, casting to a A cast to union type is similar to other casts, except that the type specified is a union type. You can specify the type either with @code{union @var{tag}} or with a typedef name. A cast to union is actually a constructor though, not a cast, and hence does not yield an lvalue like normal casts. (@xref{Compound Literals}.) The types that may be cast to the union type are those of the members of the union. Thus, given the following union and variables: @smallexample union foo @{ int i; double d; @}; int x; double y; @end smallexample @noindent both @code{x} and @code{y} can be cast to type @code{union foo}. Using the cast as the right-hand side of an assignment to a variable of union type is equivalent to storing in a member of the union: @smallexample union foo u; /* @r{@dots{}} */ u = (union foo) x @equiv{} u.i = x u = (union foo) y @equiv{} u.d = y @end smallexample You can also use the union cast as a function argument: @smallexample void hack (union foo); /* @r{@dots{}} */ hack ((union foo) x); @end smallexample @node Mixed Declarations @section Mixed Declarations and Code @cindex mixed declarations and code @cindex declarations, mixed with code @cindex code, mixed with declarations ISO C99 and ISO C++ allow declarations and code to be freely mixed within compound statements. As an extension, GCC also allows this in C89 mode. For example, you could do: @smallexample int i; /* @r{@dots{}} */ i++; int j = i + 2; @end smallexample Each identifier is visible from where it is declared until the end of the enclosing block. @node Function Attributes @section Declaring Attributes of Functions @cindex function attributes @cindex declaring attributes of functions @cindex functions that never return @cindex functions that return more than once @cindex functions that have no side effects @cindex functions in arbitrary sections @cindex functions that behave like malloc @cindex @code{volatile} applied to function @cindex @code{const} applied to function @cindex functions with @code{printf}, @code{scanf}, @code{strftime} or @code{strfmon} style arguments @cindex functions with non-null pointer arguments @cindex functions that are passed arguments in registers on the 386 @cindex functions that pop the argument stack on the 386 @cindex functions that do not pop the argument stack on the 386 In GNU C, you declare certain things about functions called in your program which help the compiler optimize function calls and check your code more carefully. The keyword @code{__attribute__} allows you to specify special attributes when making a declaration. This keyword is followed by an attribute specification inside double parentheses. The following attributes are currently defined for functions on all targets: @code{noreturn}, @code{returns_twice}, @code{noinline}, @code{always_inline}, @code{flatten}, @code{pure}, @code{const}, @code{nothrow}, @code{sentinel}, @code{format}, @code{format_arg}, @code{no_instrument_function}, @code{section}, @code{constructor}, @code{destructor}, @code{used}, @code{unused}, @code{deprecated}, @code{weak}, @code{malloc}, @code{alias}, @code{warn_unused_result}, @code{nonnull}, @code{gnu_inline} and @code{externally_visible}. Several other attributes are defined for functions on particular target systems. Other attributes, including @code{section} are supported for variables declarations (@pxref{Variable Attributes}) and for types (@pxref{Type Attributes}). You may also specify attributes with @samp{__} preceding and following each keyword. This allows you to use them in header files without being concerned about a possible macro of the same name. For example, you may use @code{__noreturn__} instead of @code{noreturn}. @xref{Attribute Syntax}, for details of the exact syntax for using attributes. @table @code @c Keep this table alphabetized by attribute name. Treat _ as space. @item alias ("@var{target}") @cindex @code{alias} attribute The @code{alias} attribute causes the declaration to be emitted as an alias for another symbol, which must be specified. For instance, @smallexample void __f () @{ /* @r{Do something.} */; @} void f () __attribute__ ((weak, alias ("__f"))); @end smallexample defines @samp{f} to be a weak alias for @samp{__f}. In C++, the mangled name for the target must be used. It is an error if @samp{__f} is not defined in the same translation unit. Not all target machines support this attribute. @item always_inline @cindex @code{always_inline} function attribute Generally, functions are not inlined unless optimization is specified. For functions declared inline, this attribute inlines the function even if no optimization level was specified. @item gnu_inline @cindex @code{gnu_inline} function attribute This attribute should be used with a function which is also declared with the @code{inline} keyword. It directs GCC to treat the function as if it were defined in gnu89 mode even when compiling in C99 or gnu99 mode. If the function is declared @code{extern}, then this definition of the function is used only for inlining. In no case is the function compiled as a standalone function, not even if you take its address explicitly. Such an address becomes an external reference, as if you had only declared the function, and had not defined it. This has almost the effect of a macro. The way to use this is to put a function definition in a header file with this attribute, and put another copy of the function, without @code{extern}, in a library file. The definition in the header file will cause most calls to the function to be inlined. If any uses of the function remain, they will refer to the single copy in the library. Note that the two definitions of the functions need not be precisely the same, although if they do not have the same effect your program may behave oddly. If the function is neither @code{extern} nor @code{static}, then the function is compiled as a standalone function, as well as being inlined where possible. This is how GCC traditionally handled functions declared @code{inline}. Since ISO C99 specifies a different semantics for @code{inline}, this function attribute is provided as a transition measure and as a useful feature in its own right. This attribute is available in GCC 4.1.3 and later. It is available if either of the preprocessor macros @code{__GNUC_GNU_INLINE__} or @code{__GNUC_STDC_INLINE__} are defined. @xref{Inline,,An Inline Function is As Fast As a Macro}. Note that since the first version of GCC to support C99 inline semantics is 4.3, earlier versions of GCC which accept this attribute effectively assume that it is always present, whether or not it is given explicitly. In versions prior to 4.3, the only effect of explicitly including it is to disable warnings about using inline functions in C99 mode. @cindex @code{flatten} function attribute @item flatten Generally, inlining into a function is limited. For a function marked with this attribute, every call inside this function will be inlined, if possible. Whether the function itself is considered for inlining depends on its size and the current inlining parameters. The @code{flatten} attribute only works reliably in unit-at-a-time mode. @item cdecl @cindex functions that do pop the argument stack on the 386 @opindex mrtd On the Intel 386, the @code{cdecl} attribute causes the compiler to assume that the calling function will pop off the stack space used to pass arguments. This is useful to override the effects of the @option{-mrtd} switch. @item const @cindex @code{const} function attribute Many functions do not examine any values except their arguments, and have no effects except the return value. Basically this is just slightly more strict class than the @code{pure} attribute below, since function is not allowed to read global memory. @cindex pointer arguments Note that a function that has pointer arguments and examines the data pointed to must @emph{not} be declared @code{const}. Likewise, a function that calls a non-@code{const} function usually must not be @code{const}. It does not make sense for a @code{const} function to return @code{void}. The attribute @code{const} is not implemented in GCC versions earlier than 2.5. An alternative way to declare that a function has no side effects, which works in the current version and in some older versions, is as follows: @smallexample typedef int intfn (); extern const intfn square; @end smallexample This approach does not work in GNU C++ from 2.6.0 on, since the language specifies that the @samp{const} must be attached to the return value. @item constructor @itemx destructor @cindex @code{constructor} function attribute @cindex @code{destructor} function attribute The @code{constructor} attribute causes the function to be called automatically before execution enters @code{main ()}. Similarly, the @code{destructor} attribute causes the function to be called automatically after @code{main ()} has completed or @code{exit ()} has been called. Functions with these attributes are useful for initializing data that will be used implicitly during the execution of the program. -These attributes are not currently implemented for Objective-C@. - @item deprecated @cindex @code{deprecated} attribute. The @code{deprecated} attribute results in a warning if the function is used anywhere in the source file. This is useful when identifying functions that are expected to be removed in a future version of a program. The warning also includes the location of the declaration of the deprecated function, to enable users to easily find further information about why the function is deprecated, or what they should do instead. Note that the warnings only occurs for uses: @smallexample int old_fn () __attribute__ ((deprecated)); int old_fn (); int (*fn_ptr)() = old_fn; @end smallexample results in a warning on line 3 but not line 2. The @code{deprecated} attribute can also be used for variables and types (@pxref{Variable Attributes}, @pxref{Type Attributes}.) @item dllexport @cindex @code{__declspec(dllexport)} On Microsoft Windows targets and Symbian OS targets the @code{dllexport} attribute causes the compiler to provide a global pointer to a pointer in a DLL, so that it can be referenced with the @code{dllimport} attribute. On Microsoft Windows targets, the pointer name is formed by combining @code{_imp__} and the function or variable name. You can use @code{__declspec(dllexport)} as a synonym for @code{__attribute__ ((dllexport))} for compatibility with other compilers. On systems that support the @code{visibility} attribute, this attribute also implies ``default'' visibility, unless a @code{visibility} attribute is explicitly specified. You should avoid the use of @code{dllexport} with ``hidden'' or ``internal'' visibility; in the future GCC may issue an error for those cases. Currently, the @code{dllexport} attribute is ignored for inlined functions, unless the @option{-fkeep-inline-functions} flag has been used. The attribute is also ignored for undefined symbols. When applied to C++ classes, the attribute marks defined non-inlined member functions and static data members as exports. Static consts initialized in-class are not marked unless they are also defined out-of-class. For Microsoft Windows targets there are alternative methods for including the symbol in the DLL's export table such as using a @file{.def} file with an @code{EXPORTS} section or, with GNU ld, using the @option{--export-all} linker flag. @item dllimport @cindex @code{__declspec(dllimport)} On Microsoft Windows and Symbian OS targets, the @code{dllimport} attribute causes the compiler to reference a function or variable via a global pointer to a pointer that is set up by the DLL exporting the symbol. The attribute implies @code{extern} storage. On Microsoft Windows targets, the pointer name is formed by combining @code{_imp__} and the function or variable name. You can use @code{__declspec(dllimport)} as a synonym for @code{__attribute__ ((dllimport))} for compatibility with other compilers. Currently, the attribute is ignored for inlined functions. If the attribute is applied to a symbol @emph{definition}, an error is reported. If a symbol previously declared @code{dllimport} is later defined, the attribute is ignored in subsequent references, and a warning is emitted. The attribute is also overridden by a subsequent declaration as @code{dllexport}. When applied to C++ classes, the attribute marks non-inlined member functions and static data members as imports. However, the attribute is ignored for virtual methods to allow creation of vtables using thunks. On the SH Symbian OS target the @code{dllimport} attribute also has another affect---it can cause the vtable and run-time type information for a class to be exported. This happens when the class has a dllimport'ed constructor or a non-inline, non-pure virtual function and, for either of those two conditions, the class also has a inline constructor or destructor and has a key function that is defined in the current translation unit. For Microsoft Windows based targets the use of the @code{dllimport} attribute on functions is not necessary, but provides a small performance benefit by eliminating a thunk in the DLL@. The use of the @code{dllimport} attribute on imported variables was required on older versions of the GNU linker, but can now be avoided by passing the @option{--enable-auto-import} switch to the GNU linker. As with functions, using the attribute for a variable eliminates a thunk in the DLL@. One drawback to using this attribute is that a pointer to a function or variable marked as @code{dllimport} cannot be used as a constant address. On Microsoft Windows targets, the attribute can be disabled for functions by setting the @option{-mnop-fun-dllimport} flag. @item eightbit_data @cindex eight bit data on the H8/300, H8/300H, and H8S Use this attribute on the H8/300, H8/300H, and H8S to indicate that the specified variable should be placed into the eight bit data section. The compiler will generate more efficient code for certain operations on data in the eight bit data area. Note the eight bit data area is limited to 256 bytes of data. You must use GAS and GLD from GNU binutils version 2.7 or later for this attribute to work correctly. @item exception_handler @cindex exception handler functions on the Blackfin processor Use this attribute on the Blackfin to indicate that the specified function is an exception handler. The compiler will generate function entry and exit sequences suitable for use in an exception handler when this attribute is present. @item far @cindex functions which handle memory bank switching On 68HC11 and 68HC12 the @code{far} attribute causes the compiler to use a calling convention that takes care of switching memory banks when entering and leaving a function. This calling convention is also the default when using the @option{-mlong-calls} option. On 68HC12 the compiler will use the @code{call} and @code{rtc} instructions to call and return from a function. On 68HC11 the compiler will generate a sequence of instructions to invoke a board-specific routine to switch the memory bank and call the real function. The board-specific routine simulates a @code{call}. At the end of a function, it will jump to a board-specific routine instead of using @code{rts}. The board-specific return routine simulates the @code{rtc}. @item fastcall @cindex functions that pop the argument stack on the 386 On the Intel 386, the @code{fastcall} attribute causes the compiler to pass the first argument (if of integral type) in the register ECX and the second argument (if of integral type) in the register EDX@. Subsequent and other typed arguments are passed on the stack. The called function will pop the arguments off the stack. If the number of arguments is variable all arguments are pushed on the stack. @item format (@var{archetype}, @var{string-index}, @var{first-to-check}) @cindex @code{format} function attribute @opindex Wformat The @code{format} attribute specifies that a function takes @code{printf}, @code{scanf}, @code{strftime} or @code{strfmon} style arguments which should be type-checked against a format string. For example, the declaration: @smallexample extern int my_printf (void *my_object, const char *my_format, ...) __attribute__ ((format (printf, 2, 3))); @end smallexample @noindent causes the compiler to check the arguments in calls to @code{my_printf} for consistency with the @code{printf} style format string argument @code{my_format}. The parameter @var{archetype} determines how the format string is interpreted, and should be @code{printf}, @code{scanf}, @code{strftime} or @code{strfmon}. (You can also use @code{__printf__}, @code{__scanf__}, @code{__strftime__} or @code{__strfmon__}.) The parameter @var{string-index} specifies which argument is the format string argument (starting from 1), while @var{first-to-check} is the number of the first argument to check against the format string. For functions where the arguments are not available to be checked (such as @code{vprintf}), specify the third parameter as zero. In this case the compiler only checks the format string for consistency. For @code{strftime} formats, the third parameter is required to be zero. Since non-static C++ methods have an implicit @code{this} argument, the arguments of such methods should be counted from two, not one, when giving values for @var{string-index} and @var{first-to-check}. In the example above, the format string (@code{my_format}) is the second argument of the function @code{my_print}, and the arguments to check start with the third argument, so the correct parameters for the format attribute are 2 and 3. @opindex ffreestanding @opindex fno-builtin The @code{format} attribute allows you to identify your own functions which take format strings as arguments, so that GCC can check the calls to these functions for errors. The compiler always (unless @option{-ffreestanding} or @option{-fno-builtin} is used) checks formats for the standard library functions @code{printf}, @code{fprintf}, @code{sprintf}, @code{scanf}, @code{fscanf}, @code{sscanf}, @code{strftime}, @code{vprintf}, @code{vfprintf} and @code{vsprintf} whenever such warnings are requested (using @option{-Wformat}), so there is no need to modify the header file @file{stdio.h}. In C99 mode, the functions @code{snprintf}, @code{vsnprintf}, @code{vscanf}, @code{vfscanf} and @code{vsscanf} are also checked. Except in strictly conforming C standard modes, the X/Open function @code{strfmon} is also checked as are @code{printf_unlocked} and @code{fprintf_unlocked}. @xref{C Dialect Options,,Options Controlling C Dialect}. The target may provide additional types of format checks. @xref{Target Format Checks,,Format Checks Specific to Particular Target Machines}. @item format_arg (@var{string-index}) @cindex @code{format_arg} function attribute @opindex Wformat-nonliteral The @code{format_arg} attribute specifies that a function takes a format string for a @code{printf}, @code{scanf}, @code{strftime} or @code{strfmon} style function and modifies it (for example, to translate it into another language), so the result can be passed to a @code{printf}, @code{scanf}, @code{strftime} or @code{strfmon} style function (with the remaining arguments to the format function the same as they would have been for the unmodified string). For example, the declaration: @smallexample extern char * my_dgettext (char *my_domain, const char *my_format) __attribute__ ((format_arg (2))); @end smallexample @noindent causes the compiler to check the arguments in calls to a @code{printf}, @code{scanf}, @code{strftime} or @code{strfmon} type function, whose format string argument is a call to the @code{my_dgettext} function, for consistency with the format string argument @code{my_format}. If the @code{format_arg} attribute had not been specified, all the compiler could tell in such calls to format functions would be that the format string argument is not constant; this would generate a warning when @option{-Wformat-nonliteral} is used, but the calls could not be checked without the attribute. The parameter @var{string-index} specifies which argument is the format string argument (starting from one). Since non-static C++ methods have an implicit @code{this} argument, the arguments of such methods should be counted from two. The @code{format-arg} attribute allows you to identify your own functions which modify format strings, so that GCC can check the calls to @code{printf}, @code{scanf}, @code{strftime} or @code{strfmon} type function whose operands are a call to one of your own function. The compiler always treats @code{gettext}, @code{dgettext}, and @code{dcgettext} in this manner except when strict ISO C support is requested by @option{-ansi} or an appropriate @option{-std} option, or @option{-ffreestanding} or @option{-fno-builtin} is used. @xref{C Dialect Options,,Options Controlling C Dialect}. @item function_vector @cindex calling functions through the function vector on the H8/300 processors Use this attribute on the H8/300, H8/300H, and H8S to indicate that the specified function should be called through the function vector. Calling a function through the function vector will reduce code size, however; the function vector has a limited size (maximum 128 entries on the H8/300 and 64 entries on the H8/300H and H8S) and shares space with the interrupt vector. You must use GAS and GLD from GNU binutils version 2.7 or later for this attribute to work correctly. @item interrupt @cindex interrupt handler functions Use this attribute on the ARM, AVR, C4x, CRX, M32C, M32R/D, MS1, and Xstormy16 ports to indicate that the specified function is an interrupt handler. The compiler will generate function entry and exit sequences suitable for use in an interrupt handler when this attribute is present. Note, interrupt handlers for the Blackfin, m68k, H8/300, H8/300H, H8S, and SH processors can be specified via the @code{interrupt_handler} attribute. Note, on the AVR, interrupts will be enabled inside the function. Note, for the ARM, you can specify the kind of interrupt to be handled by adding an optional parameter to the interrupt attribute like this: @smallexample void f () __attribute__ ((interrupt ("IRQ"))); @end smallexample Permissible values for this parameter are: IRQ, FIQ, SWI, ABORT and UNDEF@. @item interrupt_handler @cindex interrupt handler functions on the Blackfin, m68k, H8/300 and SH processors Use this attribute on the Blackfin, m68k, H8/300, H8/300H, H8S, and SH to indicate that the specified function is an interrupt handler. The compiler will generate function entry and exit sequences suitable for use in an interrupt handler when this attribute is present. @item kspisusp @cindex User stack pointer in interrupts on the Blackfin When used together with @code{interrupt_handler}, @code{exception_handler} or @code{nmi_handler}, code will be generated to load the stack pointer from the USP register in the function prologue. @item long_call/short_call @cindex indirect calls on ARM This attribute specifies how a particular function is called on ARM@. Both attributes override the @option{-mlong-calls} (@pxref{ARM Options}) command line switch and @code{#pragma long_calls} settings. The @code{long_call} attribute indicates that the function might be far away from the call site and require a different (more expensive) calling sequence. The @code{short_call} attribute always places the offset to the function from the call site into the @samp{BL} instruction directly. @item longcall/shortcall @cindex functions called via pointer on the RS/6000 and PowerPC On the Blackfin, RS/6000 and PowerPC, the @code{longcall} attribute indicates that the function might be far away from the call site and require a different (more expensive) calling sequence. The @code{shortcall} attribute indicates that the function is always close enough for the shorter calling sequence to be used. These attributes override both the @option{-mlongcall} switch and, on the RS/6000 and PowerPC, the @code{#pragma longcall} setting. @xref{RS/6000 and PowerPC Options}, for more information on whether long calls are necessary. @item long_call @cindex indirect calls on MIPS This attribute specifies how a particular function is called on MIPS@. The attribute overrides the @option{-mlong-calls} (@pxref{MIPS Options}) command line switch. This attribute causes the compiler to always call the function by first loading its address into a register, and then using the contents of that register. @item malloc @cindex @code{malloc} attribute The @code{malloc} attribute is used to tell the compiler that a function may be treated as if any non-@code{NULL} pointer it returns cannot alias any other pointer valid when the function returns. This will often improve optimization. Standard functions with this property include @code{malloc} and @code{calloc}. @code{realloc}-like functions have this property as long as the old pointer is never referred to (including comparing it to the new pointer) after the function returns a non-@code{NULL} value. @item model (@var{model-name}) @cindex function addressability on the M32R/D @cindex variable addressability on the IA-64 On the M32R/D, use this attribute to set the addressability of an object, and of the code generated for a function. The identifier @var{model-name} is one of @code{small}, @code{medium}, or @code{large}, representing each of the code models. Small model objects live in the lower 16MB of memory (so that their addresses can be loaded with the @code{ld24} instruction), and are callable with the @code{bl} instruction. Medium model objects may live anywhere in the 32-bit address space (the compiler will generate @code{seth/add3} instructions to load their addresses), and are callable with the @code{bl} instruction. Large model objects may live anywhere in the 32-bit address space (the compiler will generate @code{seth/add3} instructions to load their addresses), and may not be reachable with the @code{bl} instruction (the compiler will generate the much slower @code{seth/add3/jl} instruction sequence). On IA-64, use this attribute to set the addressability of an object. At present, the only supported identifier for @var{model-name} is @code{small}, indicating addressability via ``small'' (22-bit) addresses (so that their addresses can be loaded with the @code{addl} instruction). Caveat: such addressing is by definition not position independent and hence this attribute must not be used for objects defined by shared libraries. @item naked @cindex function without a prologue/epilogue code Use this attribute on the ARM, AVR, C4x and IP2K ports to indicate that the specified function does not need prologue/epilogue sequences generated by the compiler. It is up to the programmer to provide these sequences. @item near @cindex functions which do not handle memory bank switching on 68HC11/68HC12 On 68HC11 and 68HC12 the @code{near} attribute causes the compiler to use the normal calling convention based on @code{jsr} and @code{rts}. This attribute can be used to cancel the effect of the @option{-mlong-calls} option. @item nesting @cindex Allow nesting in an interrupt handler on the Blackfin processor. Use this attribute together with @code{interrupt_handler}, @code{exception_handler} or @code{nmi_handler} to indicate that the function entry code should enable nested interrupts or exceptions. @item nmi_handler @cindex NMI handler functions on the Blackfin processor Use this attribute on the Blackfin to indicate that the specified function is an NMI handler. The compiler will generate function entry and exit sequences suitable for use in an NMI handler when this attribute is present. @item no_instrument_function @cindex @code{no_instrument_function} function attribute @opindex finstrument-functions If @option{-finstrument-functions} is given, profiling function calls will be generated at entry and exit of most user-compiled functions. Functions with this attribute will not be so instrumented. @item noinline @cindex @code{noinline} function attribute This function attribute prevents a function from being considered for inlining. @item nonnull (@var{arg-index}, @dots{}) @cindex @code{nonnull} function attribute The @code{nonnull} attribute specifies that some function parameters should be non-null pointers. For instance, the declaration: @smallexample extern void * my_memcpy (void *dest, const void *src, size_t len) __attribute__((nonnull (1, 2))); @end smallexample @noindent causes the compiler to check that, in calls to @code{my_memcpy}, arguments @var{dest} and @var{src} are non-null. If the compiler determines that a null pointer is passed in an argument slot marked as non-null, and the @option{-Wnonnull} option is enabled, a warning is issued. The compiler may also choose to make optimizations based on the knowledge that certain function arguments will not be null. If no argument index list is given to the @code{nonnull} attribute, all pointer arguments are marked as non-null. To illustrate, the following declaration is equivalent to the previous example: @smallexample extern void * my_memcpy (void *dest, const void *src, size_t len) __attribute__((nonnull)); @end smallexample @item noreturn @cindex @code{noreturn} function attribute A few standard library functions, such as @code{abort} and @code{exit}, cannot return. GCC knows this automatically. Some programs define their own functions that never return. You can declare them @code{noreturn} to tell the compiler this fact. For example, @smallexample @group void fatal () __attribute__ ((noreturn)); void fatal (/* @r{@dots{}} */) @{ /* @r{@dots{}} */ /* @r{Print error message.} */ /* @r{@dots{}} */ exit (1); @} @end group @end smallexample The @code{noreturn} keyword tells the compiler to assume that @code{fatal} cannot return. It can then optimize without regard to what would happen if @code{fatal} ever did return. This makes slightly better code. More importantly, it helps avoid spurious warnings of uninitialized variables. The @code{noreturn} keyword does not affect the exceptional path when that applies: a @code{noreturn}-marked function may still return to the caller by throwing an exception or calling @code{longjmp}. Do not assume that registers saved by the calling function are restored before calling the @code{noreturn} function. It does not make sense for a @code{noreturn} function to have a return type other than @code{void}. The attribute @code{noreturn} is not implemented in GCC versions earlier than 2.5. An alternative way to declare that a function does not return, which works in the current version and in some older versions, is as follows: @smallexample typedef void voidfn (); volatile voidfn fatal; @end smallexample This approach does not work in GNU C++. @item nothrow @cindex @code{nothrow} function attribute The @code{nothrow} attribute is used to inform the compiler that a function cannot throw an exception. For example, most functions in the standard C library can be guaranteed not to throw an exception with the notable exceptions of @code{qsort} and @code{bsearch} that take function pointer arguments. The @code{nothrow} attribute is not implemented in GCC versions earlier than 3.3. @item pure @cindex @code{pure} function attribute Many functions have no effects except the return value and their return value depends only on the parameters and/or global variables. Such a function can be subject to common subexpression elimination and loop optimization just as an arithmetic operator would be. These functions should be declared with the attribute @code{pure}. For example, @smallexample int square (int) __attribute__ ((pure)); @end smallexample @noindent says that the hypothetical function @code{square} is safe to call fewer times than the program says. Some of common examples of pure functions are @code{strlen} or @code{memcmp}. Interesting non-pure functions are functions with infinite loops or those depending on volatile memory or other system resource, that may change between two consecutive calls (such as @code{feof} in a multithreading environment). The attribute @code{pure} is not implemented in GCC versions earlier than 2.96. @item regparm (@var{number}) @cindex @code{regparm} attribute @cindex functions that are passed arguments in registers on the 386 On the Intel 386, the @code{regparm} attribute causes the compiler to pass arguments number one to @var{number} if they are of integral type in registers EAX, EDX, and ECX instead of on the stack. Functions that take a variable number of arguments will continue to be passed all of their arguments on the stack. Beware that on some ELF systems this attribute is unsuitable for global functions in shared libraries with lazy binding (which is the default). Lazy binding will send the first call via resolving code in the loader, which might assume EAX, EDX and ECX can be clobbered, as per the standard calling conventions. Solaris 8 is affected by this. GNU systems with GLIBC 2.1 or higher, and FreeBSD, are believed to be safe since the loaders there save all registers. (Lazy binding can be disabled with the linker or the loader if desired, to avoid the problem.) @item sseregparm @cindex @code{sseregparm} attribute On the Intel 386 with SSE support, the @code{sseregparm} attribute causes the compiler to pass up to 3 floating point arguments in SSE registers instead of on the stack. Functions that take a variable number of arguments will continue to pass all of their floating point arguments on the stack. @item force_align_arg_pointer @cindex @code{force_align_arg_pointer} attribute On the Intel x86, the @code{force_align_arg_pointer} attribute may be applied to individual function definitions, generating an alternate prologue and epilogue that realigns the runtime stack. This supports mixing legacy codes that run with a 4-byte aligned stack with modern codes that keep a 16-byte stack for SSE compatibility. The alternate prologue and epilogue are slower and bigger than the regular ones, and the alternate prologue requires a scratch register; this lowers the number of registers available if used in conjunction with the @code{regparm} attribute. The @code{force_align_arg_pointer} attribute is incompatible with nested functions; this is considered a hard error. @item returns_twice @cindex @code{returns_twice} attribute The @code{returns_twice} attribute tells the compiler that a function may return more than one time. The compiler will ensure that all registers are dead before calling such a function and will emit a warning about the variables that may be clobbered after the second return from the function. Examples of such functions are @code{setjmp} and @code{vfork}. The @code{longjmp}-like counterpart of such function, if any, might need to be marked with the @code{noreturn} attribute. @item saveall @cindex save all registers on the Blackfin, H8/300, H8/300H, and H8S Use this attribute on the Blackfin, H8/300, H8/300H, and H8S to indicate that all registers except the stack pointer should be saved in the prologue regardless of whether they are used or not. @item section ("@var{section-name}") @cindex @code{section} function attribute Normally, the compiler places the code it generates in the @code{text} section. Sometimes, however, you need additional sections, or you need certain particular functions to appear in special sections. The @code{section} attribute specifies that a function lives in a particular section. For example, the declaration: @smallexample extern void foobar (void) __attribute__ ((section ("bar"))); @end smallexample @noindent puts the function @code{foobar} in the @code{bar} section. Some file formats do not support arbitrary sections so the @code{section} attribute is not available on all platforms. If you need to map the entire contents of a module to a particular section, consider using the facilities of the linker instead. @item sentinel @cindex @code{sentinel} function attribute This function attribute ensures that a parameter in a function call is an explicit @code{NULL}. The attribute is only valid on variadic functions. By default, the sentinel is located at position zero, the last parameter of the function call. If an optional integer position argument P is supplied to the attribute, the sentinel must be located at position P counting backwards from the end of the argument list. @smallexample __attribute__ ((sentinel)) is equivalent to __attribute__ ((sentinel(0))) @end smallexample The attribute is automatically set with a position of 0 for the built-in functions @code{execl} and @code{execlp}. The built-in function @code{execle} has the attribute set with a position of 1. A valid @code{NULL} in this context is defined as zero with any pointer type. If your system defines the @code{NULL} macro with an integer type then you need to add an explicit cast. GCC replaces @code{stddef.h} with a copy that redefines NULL appropriately. The warnings for missing or incorrect sentinels are enabled with @option{-Wformat}. @item short_call See long_call/short_call. @item shortcall See longcall/shortcall. @item signal @cindex signal handler functions on the AVR processors Use this attribute on the AVR to indicate that the specified function is a signal handler. The compiler will generate function entry and exit sequences suitable for use in a signal handler when this attribute is present. Interrupts will be disabled inside the function. @item sp_switch Use this attribute on the SH to indicate an @code{interrupt_handler} function should switch to an alternate stack. It expects a string argument that names a global variable holding the address of the alternate stack. @smallexample void *alt_stack; void f () __attribute__ ((interrupt_handler, sp_switch ("alt_stack"))); @end smallexample @item stdcall @cindex functions that pop the argument stack on the 386 On the Intel 386, the @code{stdcall} attribute causes the compiler to assume that the called function will pop off the stack space used to pass arguments, unless it takes a variable number of arguments. @item tiny_data @cindex tiny data section on the H8/300H and H8S Use this attribute on the H8/300H and H8S to indicate that the specified variable should be placed into the tiny data section. The compiler will generate more efficient code for loads and stores on data in the tiny data section. Note the tiny data area is limited to slightly under 32kbytes of data. @item trap_exit Use this attribute on the SH for an @code{interrupt_handler} to return using @code{trapa} instead of @code{rte}. This attribute expects an integer argument specifying the trap number to be used. @item unused @cindex @code{unused} attribute. This attribute, attached to a function, means that the function is meant to be possibly unused. GCC will not produce a warning for this function. @item used @cindex @code{used} attribute. This attribute, attached to a function, means that code must be emitted for the function even if it appears that the function is not referenced. This is useful, for example, when the function is referenced only in inline assembly. @item visibility ("@var{visibility_type}") @cindex @code{visibility} attribute This attribute affects the linkage of the declaration to which it is attached. There are four supported @var{visibility_type} values: default, hidden, protected or internal visibility. @smallexample void __attribute__ ((visibility ("protected"))) f () @{ /* @r{Do something.} */; @} int i __attribute__ ((visibility ("hidden"))); @end smallexample The possible values of @var{visibility_type} correspond to the visibility settings in the ELF gABI. @table @dfn @c keep this list of visibilities in alphabetical order. @item default Default visibility is the normal case for the object file format. This value is available for the visibility attribute to override other options that may change the assumed visibility of entities. On ELF, default visibility means that the declaration is visible to other modules and, in shared libraries, means that the declared entity may be overridden. On Darwin, default visibility means that the declaration is visible to other modules. Default visibility corresponds to ``external linkage'' in the language. @item hidden Hidden visibility indicates that the entity declared will have a new form of linkage, which we'll call ``hidden linkage''. Two declarations of an object with hidden linkage refer to the same object if they are in the same shared object. @item internal Internal visibility is like hidden visibility, but with additional processor specific semantics. Unless otherwise specified by the psABI, GCC defines internal visibility to mean that a function is @emph{never} called from another module. Compare this with hidden functions which, while they cannot be referenced directly by other modules, can be referenced indirectly via function pointers. By indicating that a function cannot be called from outside the module, GCC may for instance omit the load of a PIC register since it is known that the calling function loaded the correct value. @item protected Protected visibility is like default visibility except that it indicates that references within the defining module will bind to the definition in that module. That is, the declared entity cannot be overridden by another module. @end table All visibilities are supported on many, but not all, ELF targets (supported when the assembler supports the @samp{.visibility} pseudo-op). Default visibility is supported everywhere. Hidden visibility is supported on Darwin targets. The visibility attribute should be applied only to declarations which would otherwise have external linkage. The attribute should be applied consistently, so that the same entity should not be declared with different settings of the attribute. In C++, the visibility attribute applies to types as well as functions and objects, because in C++ types have linkage. A class must not have greater visibility than its non-static data member types and bases, and class members default to the visibility of their class. Also, a declaration without explicit visibility is limited to the visibility of its type. In C++, you can mark member functions and static member variables of a class with the visibility attribute. This is useful if if you know a particular method or static member variable should only be used from one shared object; then you can mark it hidden while the rest of the class has default visibility. Care must be taken to avoid breaking the One Definition Rule; for example, it is usually not useful to mark an inline method as hidden without marking the whole class as hidden. A C++ namespace declaration can also have the visibility attribute. This attribute applies only to the particular namespace body, not to other definitions of the same namespace; it is equivalent to using @samp{#pragma GCC visibility} before and after the namespace definition (@pxref{Visibility Pragmas}). In C++, if a template argument has limited visibility, this restriction is implicitly propagated to the template instantiation. Otherwise, template instantiations and specializations default to the visibility of their template. If both the template and enclosing class have explicit visibility, the visibility from the template is used. @item warn_unused_result @cindex @code{warn_unused_result} attribute The @code{warn_unused_result} attribute causes a warning to be emitted if a caller of the function with this attribute does not use its return value. This is useful for functions where not checking the result is either a security problem or always a bug, such as @code{realloc}. @smallexample int fn () __attribute__ ((warn_unused_result)); int foo () @{ if (fn () < 0) return -1; fn (); return 0; @} @end smallexample results in warning on line 5. @item weak @cindex @code{weak} attribute The @code{weak} attribute causes the declaration to be emitted as a weak symbol rather than a global. This is primarily useful in defining library functions which can be overridden in user code, though it can also be used with non-function declarations. Weak symbols are supported for ELF targets, and also for a.out targets when using the GNU assembler and linker. @item weakref @itemx weakref ("@var{target}") @cindex @code{weakref} attribute The @code{weakref} attribute marks a declaration as a weak reference. Without arguments, it should be accompanied by an @code{alias} attribute naming the target symbol. Optionally, the @var{target} may be given as an argument to @code{weakref} itself. In either case, @code{weakref} implicitly marks the declaration as @code{weak}. Without a @var{target}, given as an argument to @code{weakref} or to @code{alias}, @code{weakref} is equivalent to @code{weak}. @smallexample static int x() __attribute__ ((weakref ("y"))); /* is equivalent to... */ static int x() __attribute__ ((weak, weakref, alias ("y"))); /* and to... */ static int x() __attribute__ ((weakref)); static int x() __attribute__ ((alias ("y"))); @end smallexample A weak reference is an alias that does not by itself require a definition to be given for the target symbol. If the target symbol is only referenced through weak references, then the becomes a @code{weak} undefined symbol. If it is directly referenced, however, then such strong references prevail, and a definition will be required for the symbol, not necessarily in the same translation unit. The effect is equivalent to moving all references to the alias to a separate translation unit, renaming the alias to the aliased symbol, declaring it as weak, compiling the two separate translation units and performing a reloadable link on them. At present, a declaration to which @code{weakref} is attached can only be @code{static}. @item externally_visible @cindex @code{externally_visible} attribute. This attribute, attached to a global variable or function nullify effect of @option{-fwhole-program} command line option, so the object remain visible outside the current compilation unit @end table You can specify multiple attributes in a declaration by separating them by commas within the double parentheses or by immediately following an attribute declaration with another attribute declaration. @cindex @code{#pragma}, reason for not using @cindex pragma, reason for not using Some people object to the @code{__attribute__} feature, suggesting that ISO C's @code{#pragma} should be used instead. At the time @code{__attribute__} was designed, there were two reasons for not doing this. @enumerate @item It is impossible to generate @code{#pragma} commands from a macro. @item There is no telling what the same @code{#pragma} might mean in another compiler. @end enumerate These two reasons applied to almost any application that might have been proposed for @code{#pragma}. It was basically a mistake to use @code{#pragma} for @emph{anything}. The ISO C99 standard includes @code{_Pragma}, which now allows pragmas to be generated from macros. In addition, a @code{#pragma GCC} namespace is now in use for GCC-specific pragmas. However, it has been found convenient to use @code{__attribute__} to achieve a natural attachment of attributes to their corresponding declarations, whereas @code{#pragma GCC} is of use for constructs that do not naturally form part of the grammar. @xref{Other Directives,,Miscellaneous Preprocessing Directives, cpp, The GNU C Preprocessor}. @node Attribute Syntax @section Attribute Syntax @cindex attribute syntax This section describes the syntax with which @code{__attribute__} may be used, and the constructs to which attribute specifiers bind, for the C -language. Some details may vary for C++ and Objective-C@. Because of -infelicities in the grammar for attributes, some forms described here -may not be successfully parsed in all cases. +language. Some details may vary for C++. Because of infelicities in +the grammar for attributes, some forms described here may not be +successfully parsed in all cases. There are some problems with the semantics of attributes in C++. For example, there are no manglings for attributes, although they may affect code generation, so problems may arise when attributed types are used in conjunction with templates or overloading. Similarly, @code{typeid} does not distinguish between types with different attributes. Support for attributes in C++ may be restricted in future to attributes on declarations only, but not on nested declarators. @xref{Function Attributes}, for details of the semantics of attributes applying to functions. @xref{Variable Attributes}, for details of the semantics of attributes applying to variables. @xref{Type Attributes}, for details of the semantics of attributes applying to structure, union and enumerated types. An @dfn{attribute specifier} is of the form @code{__attribute__ ((@var{attribute-list}))}. An @dfn{attribute list} is a possibly empty comma-separated sequence of @dfn{attributes}, where each attribute is one of the following: @itemize @bullet @item Empty. Empty attributes are ignored. @item A word (which may be an identifier such as @code{unused}, or a reserved word such as @code{const}). @item A word, followed by, in parentheses, parameters for the attribute. These parameters take one of the following forms: @itemize @bullet @item An identifier. For example, @code{mode} attributes use this form. @item An identifier followed by a comma and a non-empty comma-separated list of expressions. For example, @code{format} attributes use this form. @item A possibly empty comma-separated list of expressions. For example, @code{format_arg} attributes use this form with the list being a single integer constant expression, and @code{alias} attributes use this form with the list being a single string constant. @end itemize @end itemize An @dfn{attribute specifier list} is a sequence of one or more attribute specifiers, not separated by any other tokens. In GNU C, an attribute specifier list may appear after the colon following a label, other than a @code{case} or @code{default} label. The only attribute it makes sense to use after a label is @code{unused}. This feature is intended for code generated by programs which contains labels that may be unused but which is compiled with @option{-Wall}. It would not normally be appropriate to use in it human-written code, though it could be useful in cases where the code that jumps to the label is contained within an @code{#ifdef} conditional. GNU C++ does not permit such placement of attribute lists, as it is permissible for a declaration, which could begin with an attribute list, to be labelled in C++. Declarations cannot be labelled in C90 or C99, so the ambiguity does not arise there. An attribute specifier list may appear as part of a @code{struct}, @code{union} or @code{enum} specifier. It may go either immediately after the @code{struct}, @code{union} or @code{enum} keyword, or after the closing brace. The former syntax is preferred. Where attribute specifiers follow the closing brace, they are considered to relate to the structure, union or enumerated type defined, not to any enclosing declaration the type specifier appears in, and the type defined is not complete until after the attribute specifiers. @c Otherwise, there would be the following problems: a shift/reduce @c conflict between attributes binding the struct/union/enum and @c binding to the list of specifiers/qualifiers; and "aligned" @c attributes could use sizeof for the structure, but the size could be @c changed later by "packed" attributes. Otherwise, an attribute specifier appears as part of a declaration, counting declarations of unnamed parameters and type names, and relates to that declaration (which may be nested in another declaration, for example in the case of a parameter declaration), or to a particular declarator within a declaration. Where an attribute specifier is applied to a parameter declared as a function or an array, it should apply to the function or array rather than the pointer to which the parameter is implicitly converted, but this is not yet correctly implemented. Any list of specifiers and qualifiers at the start of a declaration may contain attribute specifiers, whether or not such a list may in that context contain storage class specifiers. (Some attributes, however, are essentially in the nature of storage class specifiers, and only make sense where storage class specifiers may be used; for example, @code{section}.) There is one necessary limitation to this syntax: the first old-style parameter declaration in a function definition cannot begin with an attribute specifier, because such an attribute applies to the function instead by syntax described below (which, however, is not yet implemented in this case). In some other cases, attribute specifiers are permitted by this grammar but not yet supported by the compiler. All attribute specifiers in this place relate to the declaration as a whole. In the obsolescent usage where a type of @code{int} is implied by the absence of type specifiers, such a list of specifiers and qualifiers may be an attribute specifier list with no other specifiers or qualifiers. At present, the first parameter in a function prototype must have some type specifier which is not an attribute specifier; this resolves an ambiguity in the interpretation of @code{void f(int (__attribute__((foo)) x))}, but is subject to change. At present, if the parentheses of a function declarator contain only attributes then those attributes are ignored, rather than yielding an error or warning or implying a single parameter of type int, but this is subject to change. An attribute specifier list may appear immediately before a declarator (other than the first) in a comma-separated list of declarators in a declaration of more than one identifier using a single list of specifiers and qualifiers. Such attribute specifiers apply only to the identifier before whose declarator they appear. For example, in @smallexample __attribute__((noreturn)) void d0 (void), __attribute__((format(printf, 1, 2))) d1 (const char *, ...), d2 (void) @end smallexample @noindent the @code{noreturn} attribute applies to all the functions declared; the @code{format} attribute only applies to @code{d1}. An attribute specifier list may appear immediately before the comma, @code{=} or semicolon terminating the declaration of an identifier other than a function definition. At present, such attribute specifiers apply to the declared object or function, but in future they may attach to the outermost adjacent declarator. In simple cases there is no difference, but, for example, in @smallexample void (****f)(void) __attribute__((noreturn)); @end smallexample @noindent at present the @code{noreturn} attribute applies to @code{f}, which causes a warning since @code{f} is not a function, but in future it may apply to the function @code{****f}. The precise semantics of what attributes in such cases will apply to are not yet specified. Where an assembler name for an object or function is specified (@pxref{Asm Labels}), at present the attribute must follow the @code{asm} specification; in future, attributes before the @code{asm} specification may apply to the adjacent declarator, and those after it to the declared object or function. An attribute specifier list may, in future, be permitted to appear after the declarator in a function definition (before any old-style parameter declarations or the function body). Attribute specifiers may be mixed with type qualifiers appearing inside the @code{[]} of a parameter array declarator, in the C99 construct by which such qualifiers are applied to the pointer to which the array is implicitly converted. Such attribute specifiers apply to the pointer, not to the array, but at present this is not implemented and they are ignored. An attribute specifier list may appear at the start of a nested declarator. At present, there are some limitations in this usage: the attributes correctly apply to the declarator, but for most individual attributes the semantics this implies are not implemented. When attribute specifiers follow the @code{*} of a pointer declarator, they may be mixed with any type qualifiers present. The following describes the formal semantics of this syntax. It will make the most sense if you are familiar with the formal specification of declarators in the ISO C standard. Consider (as in C99 subclause 6.7.5 paragraph 4) a declaration @code{T D1}, where @code{T} contains declaration specifiers that specify a type @var{Type} (such as @code{int}) and @code{D1} is a declarator that contains an identifier @var{ident}. The type specified for @var{ident} for derived declarators whose type does not include an attribute specifier is as in the ISO C standard. If @code{D1} has the form @code{( @var{attribute-specifier-list} D )}, and the declaration @code{T D} specifies the type ``@var{derived-declarator-type-list} @var{Type}'' for @var{ident}, then @code{T D1} specifies the type ``@var{derived-declarator-type-list} @var{attribute-specifier-list} @var{Type}'' for @var{ident}. If @code{D1} has the form @code{* @var{type-qualifier-and-attribute-specifier-list} D}, and the declaration @code{T D} specifies the type ``@var{derived-declarator-type-list} @var{Type}'' for @var{ident}, then @code{T D1} specifies the type ``@var{derived-declarator-type-list} @var{type-qualifier-and-attribute-specifier-list} @var{Type}'' for @var{ident}. For example, @smallexample void (__attribute__((noreturn)) ****f) (void); @end smallexample @noindent specifies the type ``pointer to pointer to pointer to pointer to non-returning function returning @code{void}''. As another example, @smallexample char *__attribute__((aligned(8))) *f; @end smallexample @noindent specifies the type ``pointer to 8-byte-aligned pointer to @code{char}''. Note again that this does not work with most attributes; for example, the usage of @samp{aligned} and @samp{noreturn} attributes given above is not yet supported. For compatibility with existing code written for compiler versions that did not implement attributes on nested declarators, some laxity is allowed in the placing of attributes. If an attribute that only applies to types is applied to a declaration, it will be treated as applying to the type of that declaration. If an attribute that only applies to declarations is applied to the type of a declaration, it will be treated as applying to that declaration; and, for compatibility with code placing the attributes immediately before the identifier declared, such an attribute applied to a function return type will be treated as applying to the function type, and such an attribute applied to an array element type will be treated as applying to the array type. If an attribute that only applies to function types is applied to a pointer-to-function type, it will be treated as applying to the pointer target type; if such an attribute is applied to a function return type that is not a pointer-to-function type, it will be treated as applying to the function type. @node Function Prototypes @section Prototypes and Old-Style Function Definitions @cindex function prototype declarations @cindex old-style function definitions @cindex promotion of formal parameters GNU C extends ISO C to allow a function prototype to override a later old-style non-prototype definition. Consider the following example: @smallexample /* @r{Use prototypes unless the compiler is old-fashioned.} */ #ifdef __STDC__ #define P(x) x #else #define P(x) () #endif /* @r{Prototype function declaration.} */ int isroot P((uid_t)); /* @r{Old-style function definition.} */ int isroot (x) /* @r{??? lossage here ???} */ uid_t x; @{ return x == 0; @} @end smallexample Suppose the type @code{uid_t} happens to be @code{short}. ISO C does not allow this example, because subword arguments in old-style non-prototype definitions are promoted. Therefore in this example the function definition's argument is really an @code{int}, which does not match the prototype argument type of @code{short}. This restriction of ISO C makes it hard to write code that is portable to traditional C compilers, because the programmer does not know whether the @code{uid_t} type is @code{short}, @code{int}, or @code{long}. Therefore, in cases like these GNU C allows a prototype to override a later old-style definition. More precisely, in GNU C, a function prototype argument type overrides the argument type specified by a later old-style definition if the former type is the same as the latter type before promotion. Thus in GNU C the above example is equivalent to the following: @smallexample int isroot (uid_t); int isroot (uid_t x) @{ return x == 0; @} @end smallexample @noindent GNU C++ does not support old-style function definitions, so this extension is irrelevant. @node C++ Comments @section C++ Style Comments @cindex // @cindex C++ comments @cindex comments, C++ style In GNU C, you may use C++ style comments, which start with @samp{//} and continue until the end of the line. Many other C implementations allow such comments, and they are included in the 1999 C standard. However, C++ style comments are not recognized if you specify an @option{-std} option specifying a version of ISO C before C99, or @option{-ansi} (equivalent to @option{-std=c89}). @node Dollar Signs @section Dollar Signs in Identifier Names @cindex $ @cindex dollar signs in identifier names @cindex identifier names, dollar signs in In GNU C, you may normally use dollar signs in identifier names. This is because many traditional C implementations allow such identifiers. However, dollar signs in identifiers are not supported on a few target machines, typically because the target assembler does not allow them. @node Character Escapes @section The Character @key{ESC} in Constants You can use the sequence @samp{\e} in a string or character constant to stand for the ASCII character @key{ESC}. @node Alignment @section Inquiring on Alignment of Types or Variables @cindex alignment @cindex type alignment @cindex variable alignment The keyword @code{__alignof__} allows you to inquire about how an object is aligned, or the minimum alignment usually required by a type. Its syntax is just like @code{sizeof}. For example, if the target machine requires a @code{double} value to be aligned on an 8-byte boundary, then @code{__alignof__ (double)} is 8. This is true on many RISC machines. On more traditional machine designs, @code{__alignof__ (double)} is 4 or even 2. Some machines never actually require alignment; they allow reference to any data type even at an odd address. For these machines, @code{__alignof__} reports the @emph{recommended} alignment of a type. If the operand of @code{__alignof__} is an lvalue rather than a type, its value is the required alignment for its type, taking into account any minimum alignment specified with GCC's @code{__attribute__} extension (@pxref{Variable Attributes}). For example, after this declaration: @smallexample struct foo @{ int x; char y; @} foo1; @end smallexample @noindent the value of @code{__alignof__ (foo1.y)} is 1, even though its actual alignment is probably 2 or 4, the same as @code{__alignof__ (int)}. It is an error to ask for the alignment of an incomplete type. @node Variable Attributes @section Specifying Attributes of Variables @cindex attribute of variables @cindex variable attributes The keyword @code{__attribute__} allows you to specify special attributes of variables or structure fields. This keyword is followed by an attribute specification inside double parentheses. Some attributes are currently defined generically for variables. Other attributes are defined for variables on particular target systems. Other attributes are available for functions (@pxref{Function Attributes}) and for types (@pxref{Type Attributes}). Other front ends might define more attributes (@pxref{C++ Extensions,,Extensions to the C++ Language}). You may also specify attributes with @samp{__} preceding and following each keyword. This allows you to use them in header files without being concerned about a possible macro of the same name. For example, you may use @code{__aligned__} instead of @code{aligned}. @xref{Attribute Syntax}, for details of the exact syntax for using attributes. @table @code @cindex @code{aligned} attribute @item aligned (@var{alignment}) This attribute specifies a minimum alignment for the variable or structure field, measured in bytes. For example, the declaration: @smallexample int x __attribute__ ((aligned (16))) = 0; @end smallexample @noindent causes the compiler to allocate the global variable @code{x} on a 16-byte boundary. On a 68040, this could be used in conjunction with an @code{asm} expression to access the @code{move16} instruction which requires 16-byte aligned operands. You can also specify the alignment of structure fields. For example, to create a double-word aligned @code{int} pair, you could write: @smallexample struct foo @{ int x[2] __attribute__ ((aligned (8))); @}; @end smallexample @noindent This is an alternative to creating a union with a @code{double} member that forces the union to be double-word aligned. As in the preceding examples, you can explicitly specify the alignment (in bytes) that you wish the compiler to use for a given variable or structure field. Alternatively, you can leave out the alignment factor and just ask the compiler to align a variable or field to the maximum useful alignment for the target machine you are compiling for. For example, you could write: @smallexample short array[3] __attribute__ ((aligned)); @end smallexample Whenever you leave out the alignment factor in an @code{aligned} attribute specification, the compiler automatically sets the alignment for the declared variable or field to the largest alignment which is ever used for any data type on the target machine you are compiling for. Doing this can often make copy operations more efficient, because the compiler can use whatever instructions copy the biggest chunks of memory when performing copies to or from the variables or fields that you have aligned this way. The @code{aligned} attribute can only increase the alignment; but you can decrease it by specifying @code{packed} as well. See below. Note that the effectiveness of @code{aligned} attributes may be limited by inherent limitations in your linker. On many systems, the linker is only able to arrange for variables to be aligned up to a certain maximum alignment. (For some linkers, the maximum supported alignment may be very very small.) If your linker is only able to align variables up to a maximum of 8 byte alignment, then specifying @code{aligned(16)} in an @code{__attribute__} will still only provide you with 8 byte alignment. See your linker documentation for further information. @item cleanup (@var{cleanup_function}) @cindex @code{cleanup} attribute The @code{cleanup} attribute runs a function when the variable goes out of scope. This attribute can only be applied to auto function scope variables; it may not be applied to parameters or variables with static storage duration. The function must take one parameter, a pointer to a type compatible with the variable. The return value of the function (if any) is ignored. If @option{-fexceptions} is enabled, then @var{cleanup_function} will be run during the stack unwinding that happens during the processing of the exception. Note that the @code{cleanup} attribute does not allow the exception to be caught, only to perform an action. It is undefined what happens if @var{cleanup_function} does not return normally. @item common @itemx nocommon @cindex @code{common} attribute @cindex @code{nocommon} attribute @opindex fcommon @opindex fno-common The @code{common} attribute requests GCC to place a variable in ``common'' storage. The @code{nocommon} attribute requests the opposite---to allocate space for it directly. These attributes override the default chosen by the @option{-fno-common} and @option{-fcommon} flags respectively. @item deprecated @cindex @code{deprecated} attribute The @code{deprecated} attribute results in a warning if the variable is used anywhere in the source file. This is useful when identifying variables that are expected to be removed in a future version of a program. The warning also includes the location of the declaration of the deprecated variable, to enable users to easily find further information about why the variable is deprecated, or what they should do instead. Note that the warning only occurs for uses: @smallexample extern int old_var __attribute__ ((deprecated)); extern int old_var; int new_fn () @{ return old_var; @} @end smallexample results in a warning on line 3 but not line 2. The @code{deprecated} attribute can also be used for functions and types (@pxref{Function Attributes}, @pxref{Type Attributes}.) @item mode (@var{mode}) @cindex @code{mode} attribute This attribute specifies the data type for the declaration---whichever type corresponds to the mode @var{mode}. This in effect lets you request an integer or floating point type according to its width. You may also specify a mode of @samp{byte} or @samp{__byte__} to indicate the mode corresponding to a one-byte integer, @samp{word} or @samp{__word__} for the mode of a one-word integer, and @samp{pointer} or @samp{__pointer__} for the mode used to represent pointers. @item packed @cindex @code{packed} attribute The @code{packed} attribute specifies that a variable or structure field should have the smallest possible alignment---one byte for a variable, and one bit for a field, unless you specify a larger value with the @code{aligned} attribute. Here is a structure in which the field @code{x} is packed, so that it immediately follows @code{a}: @smallexample struct foo @{ char a; int x[2] __attribute__ ((packed)); @}; @end smallexample @item section ("@var{section-name}") @cindex @code{section} variable attribute Normally, the compiler places the objects it generates in sections like @code{data} and @code{bss}. Sometimes, however, you need additional sections, or you need certain particular variables to appear in special sections, for example to map to special hardware. The @code{section} attribute specifies that a variable (or function) lives in a particular section. For example, this small program uses several specific section names: @smallexample struct duart a __attribute__ ((section ("DUART_A"))) = @{ 0 @}; struct duart b __attribute__ ((section ("DUART_B"))) = @{ 0 @}; char stack[10000] __attribute__ ((section ("STACK"))) = @{ 0 @}; int init_data __attribute__ ((section ("INITDATA"))) = 0; main() @{ /* @r{Initialize stack pointer} */ init_sp (stack + sizeof (stack)); /* @r{Initialize initialized data} */ memcpy (&init_data, &data, &edata - &data); /* @r{Turn on the serial ports} */ init_duart (&a); init_duart (&b); @} @end smallexample @noindent Use the @code{section} attribute with an @emph{initialized} definition of a @emph{global} variable, as shown in the example. GCC issues a warning and otherwise ignores the @code{section} attribute in uninitialized variable declarations. You may only use the @code{section} attribute with a fully initialized global definition because of the way linkers work. The linker requires each object be defined once, with the exception that uninitialized variables tentatively go in the @code{common} (or @code{bss}) section and can be multiply ``defined''. You can force a variable to be initialized with the @option{-fno-common} flag or the @code{nocommon} attribute. Some file formats do not support arbitrary sections so the @code{section} attribute is not available on all platforms. If you need to map the entire contents of a module to a particular section, consider using the facilities of the linker instead. @item shared @cindex @code{shared} variable attribute On Microsoft Windows, in addition to putting variable definitions in a named section, the section can also be shared among all running copies of an executable or DLL@. For example, this small program defines shared data by putting it in a named section @code{shared} and marking the section shareable: @smallexample int foo __attribute__((section ("shared"), shared)) = 0; int main() @{ /* @r{Read and write foo. All running copies see the same value.} */ return 0; @} @end smallexample @noindent You may only use the @code{shared} attribute along with @code{section} attribute with a fully initialized global definition because of the way linkers work. See @code{section} attribute for more information. The @code{shared} attribute is only available on Microsoft Windows@. @item tls_model ("@var{tls_model}") @cindex @code{tls_model} attribute The @code{tls_model} attribute sets thread-local storage model (@pxref{Thread-Local}) of a particular @code{__thread} variable, overriding @option{-ftls-model=} command line switch on a per-variable basis. The @var{tls_model} argument should be one of @code{global-dynamic}, @code{local-dynamic}, @code{initial-exec} or @code{local-exec}. Not all targets support this attribute. @item unused This attribute, attached to a variable, means that the variable is meant to be possibly unused. GCC will not produce a warning for this variable. @item used This attribute, attached to a variable, means that the variable must be emitted even if it appears that the variable is not referenced. @item vector_size (@var{bytes}) This attribute specifies the vector size for the variable, measured in bytes. For example, the declaration: @smallexample int foo __attribute__ ((vector_size (16))); @end smallexample @noindent causes the compiler to set the mode for @code{foo}, to be 16 bytes, divided into @code{int} sized units. Assuming a 32-bit int (a vector of 4 units of 4 bytes), the corresponding mode of @code{foo} will be V4SI@. This attribute is only applicable to integral and float scalars, although arrays, pointers, and function return values are allowed in conjunction with this construct. Aggregates with this attribute are invalid, even if they are of the same size as a corresponding scalar. For example, the declaration: @smallexample struct S @{ int a; @}; struct S __attribute__ ((vector_size (16))) foo; @end smallexample @noindent is invalid even if the size of the structure is the same as the size of the @code{int}. @item selectany The @code{selectany} attribute causes an initialized global variable to have link-once semantics. When multiple definitions of the variable are encountered by the linker, the first is selected and the remainder are discarded. Following usage by the Microsoft compiler, the linker is told @emph{not} to warn about size or content differences of the multiple definitions. Although the primary usage of this attribute is for POD types, the attribute can also be applied to global C++ objects that are initialized by a constructor. In this case, the static initialization and destruction code for the object is emitted in each translation defining the object, but the calls to the constructor and destructor are protected by a link-once guard variable. The @code{selectany} attribute is only available on Microsoft Windows targets. You can use @code{__declspec (selectany)} as a synonym for @code{__attribute__ ((selectany))} for compatibility with other compilers. @item weak The @code{weak} attribute is described in @xref{Function Attributes}. @item dllimport The @code{dllimport} attribute is described in @xref{Function Attributes}. @item dllexport The @code{dllexport} attribute is described in @xref{Function Attributes}. @end table @subsection M32R/D Variable Attributes One attribute is currently defined for the M32R/D@. @table @code @item model (@var{model-name}) @cindex variable addressability on the M32R/D Use this attribute on the M32R/D to set the addressability of an object. The identifier @var{model-name} is one of @code{small}, @code{medium}, or @code{large}, representing each of the code models. Small model objects live in the lower 16MB of memory (so that their addresses can be loaded with the @code{ld24} instruction). Medium and large model objects may live anywhere in the 32-bit address space (the compiler will generate @code{seth/add3} instructions to load their addresses). @end table @anchor{i386 Variable Attributes} @subsection i386 Variable Attributes Two attributes are currently defined for i386 configurations: @code{ms_struct} and @code{gcc_struct} @table @code @item ms_struct @itemx gcc_struct @cindex @code{ms_struct} attribute @cindex @code{gcc_struct} attribute If @code{packed} is used on a structure, or if bit-fields are used it may be that the Microsoft ABI packs them differently than GCC would normally pack them. Particularly when moving packed data between functions compiled with GCC and the native Microsoft compiler (either via function call or as data in a file), it may be necessary to access either format. Currently @option{-m[no-]ms-bitfields} is provided for the Microsoft Windows X86 compilers to match the native Microsoft compiler. The Microsoft structure layout algorithm is fairly simple with the exception of the bitfield packing: The padding and alignment of members of structures and whether a bit field can straddle a storage-unit boundary @enumerate @item Structure members are stored sequentially in the order in which they are declared: the first member has the lowest memory address and the last member the highest. @item Every data object has an alignment-requirement. The alignment-requirement for all data except structures, unions, and arrays is either the size of the object or the current packing size (specified with either the aligned attribute or the pack pragma), whichever is less. For structures, unions, and arrays, the alignment-requirement is the largest alignment-requirement of its members. Every object is allocated an offset so that: offset % alignment-requirement == 0 @item Adjacent bit fields are packed into the same 1-, 2-, or 4-byte allocation unit if the integral types are the same size and if the next bit field fits into the current allocation unit without crossing the boundary imposed by the common alignment requirements of the bit fields. @end enumerate Handling of zero-length bitfields: MSVC interprets zero-length bitfields in the following ways: @enumerate @item If a zero-length bitfield is inserted between two bitfields that would normally be coalesced, the bitfields will not be coalesced. For example: @smallexample struct @{ unsigned long bf_1 : 12; unsigned long : 0; unsigned long bf_2 : 12; @} t1; @end smallexample The size of @code{t1} would be 8 bytes with the zero-length bitfield. If the zero-length bitfield were removed, @code{t1}'s size would be 4 bytes. @item If a zero-length bitfield is inserted after a bitfield, @code{foo}, and the alignment of the zero-length bitfield is greater than the member that follows it, @code{bar}, @code{bar} will be aligned as the type of the zero-length bitfield. For example: @smallexample struct @{ char foo : 4; short : 0; char bar; @} t2; struct @{ char foo : 4; short : 0; double bar; @} t3; @end smallexample For @code{t2}, @code{bar} will be placed at offset 2, rather than offset 1. Accordingly, the size of @code{t2} will be 4. For @code{t3}, the zero-length bitfield will not affect the alignment of @code{bar} or, as a result, the size of the structure. Taking this into account, it is important to note the following: @enumerate @item If a zero-length bitfield follows a normal bitfield, the type of the zero-length bitfield may affect the alignment of the structure as whole. For example, @code{t2} has a size of 4 bytes, since the zero-length bitfield follows a normal bitfield, and is of type short. @item Even if a zero-length bitfield is not followed by a normal bitfield, it may still affect the alignment of the structure: @smallexample struct @{ char foo : 6; long : 0; @} t4; @end smallexample Here, @code{t4} will take up 4 bytes. @end enumerate @item Zero-length bitfields following non-bitfield members are ignored: @smallexample struct @{ char foo; long : 0; char bar; @} t5; @end smallexample Here, @code{t5} will take up 2 bytes. @end enumerate @end table @subsection PowerPC Variable Attributes Three attributes currently are defined for PowerPC configurations: @code{altivec}, @code{ms_struct} and @code{gcc_struct}. For full documentation of the struct attributes please see the documentation in the @xref{i386 Variable Attributes}, section. For documentation of @code{altivec} attribute please see the documentation in the @xref{PowerPC Type Attributes}, section. @subsection Xstormy16 Variable Attributes One attribute is currently defined for xstormy16 configurations: @code{below100} @table @code @item below100 @cindex @code{below100} attribute If a variable has the @code{below100} attribute (@code{BELOW100} is allowed also), GCC will place the variable in the first 0x100 bytes of memory and use special opcodes to access it. Such variables will be placed in either the @code{.bss_below100} section or the @code{.data_below100} section. @end table @node Type Attributes @section Specifying Attributes of Types @cindex attribute of types @cindex type attributes The keyword @code{__attribute__} allows you to specify special attributes of @code{struct} and @code{union} types when you define such types. This keyword is followed by an attribute specification inside double parentheses. Seven attributes are currently defined for types: @code{aligned}, @code{packed}, @code{transparent_union}, @code{unused}, @code{deprecated}, @code{visibility}, and @code{may_alias}. Other attributes are defined for functions (@pxref{Function Attributes}) and for variables (@pxref{Variable Attributes}). You may also specify any one of these attributes with @samp{__} preceding and following its keyword. This allows you to use these attributes in header files without being concerned about a possible macro of the same name. For example, you may use @code{__aligned__} instead of @code{aligned}. You may specify type attributes either in a @code{typedef} declaration or in an enum, struct or union type declaration or definition. For an enum, struct or union type, you may specify attributes either between the enum, struct or union tag and the name of the type, or just past the closing curly brace of the @emph{definition}. The former syntax is preferred. @xref{Attribute Syntax}, for details of the exact syntax for using attributes. @table @code @cindex @code{aligned} attribute @item aligned (@var{alignment}) This attribute specifies a minimum alignment (in bytes) for variables of the specified type. For example, the declarations: @smallexample struct S @{ short f[3]; @} __attribute__ ((aligned (8))); typedef int more_aligned_int __attribute__ ((aligned (8))); @end smallexample @noindent force the compiler to insure (as far as it can) that each variable whose type is @code{struct S} or @code{more_aligned_int} will be allocated and aligned @emph{at least} on a 8-byte boundary. On a SPARC, having all variables of type @code{struct S} aligned to 8-byte boundaries allows the compiler to use the @code{ldd} and @code{std} (doubleword load and store) instructions when copying one variable of type @code{struct S} to another, thus improving run-time efficiency. Note that the alignment of any given @code{struct} or @code{union} type is required by the ISO C standard to be at least a perfect multiple of the lowest common multiple of the alignments of all of the members of the @code{struct} or @code{union} in question. This means that you @emph{can} effectively adjust the alignment of a @code{struct} or @code{union} type by attaching an @code{aligned} attribute to any one of the members of such a type, but the notation illustrated in the example above is a more obvious, intuitive, and readable way to request the compiler to adjust the alignment of an entire @code{struct} or @code{union} type. As in the preceding example, you can explicitly specify the alignment (in bytes) that you wish the compiler to use for a given @code{struct} or @code{union} type. Alternatively, you can leave out the alignment factor and just ask the compiler to align a type to the maximum useful alignment for the target machine you are compiling for. For example, you could write: @smallexample struct S @{ short f[3]; @} __attribute__ ((aligned)); @end smallexample Whenever you leave out the alignment factor in an @code{aligned} attribute specification, the compiler automatically sets the alignment for the type to the largest alignment which is ever used for any data type on the target machine you are compiling for. Doing this can often make copy operations more efficient, because the compiler can use whatever instructions copy the biggest chunks of memory when performing copies to or from the variables which have types that you have aligned this way. In the example above, if the size of each @code{short} is 2 bytes, then the size of the entire @code{struct S} type is 6 bytes. The smallest power of two which is greater than or equal to that is 8, so the compiler sets the alignment for the entire @code{struct S} type to 8 bytes. Note that although you can ask the compiler to select a time-efficient alignment for a given type and then declare only individual stand-alone objects of that type, the compiler's ability to select a time-efficient alignment is primarily useful only when you plan to create arrays of variables having the relevant (efficiently aligned) type. If you declare or use arrays of variables of an efficiently-aligned type, then it is likely that your program will also be doing pointer arithmetic (or subscripting, which amounts to the same thing) on pointers to the relevant type, and the code that the compiler generates for these pointer arithmetic operations will often be more efficient for efficiently-aligned types than for other types. The @code{aligned} attribute can only increase the alignment; but you can decrease it by specifying @code{packed} as well. See below. Note that the effectiveness of @code{aligned} attributes may be limited by inherent limitations in your linker. On many systems, the linker is only able to arrange for variables to be aligned up to a certain maximum alignment. (For some linkers, the maximum supported alignment may be very very small.) If your linker is only able to align variables up to a maximum of 8 byte alignment, then specifying @code{aligned(16)} in an @code{__attribute__} will still only provide you with 8 byte alignment. See your linker documentation for further information. @item packed This attribute, attached to @code{struct} or @code{union} type definition, specifies that each member (other than zero-width bitfields) of the structure or union is placed to minimize the memory required. When attached to an @code{enum} definition, it indicates that the smallest integral type should be used. @opindex fshort-enums Specifying this attribute for @code{struct} and @code{union} types is equivalent to specifying the @code{packed} attribute on each of the structure or union members. Specifying the @option{-fshort-enums} flag on the line is equivalent to specifying the @code{packed} attribute on all @code{enum} definitions. In the following example @code{struct my_packed_struct}'s members are packed closely together, but the internal layout of its @code{s} member is not packed---to do that, @code{struct my_unpacked_struct} would need to be packed too. @smallexample struct my_unpacked_struct @{ char c; int i; @}; struct __attribute__ ((__packed__)) my_packed_struct @{ char c; int i; struct my_unpacked_struct s; @}; @end smallexample You may only specify this attribute on the definition of a @code{enum}, @code{struct} or @code{union}, not on a @code{typedef} which does not also define the enumerated type, structure or union. @item transparent_union This attribute, attached to a @code{union} type definition, indicates that any function parameter having that union type causes calls to that function to be treated in a special way. First, the argument corresponding to a transparent union type can be of any type in the union; no cast is required. Also, if the union contains a pointer type, the corresponding argument can be a null pointer constant or a void pointer expression; and if the union contains a void pointer type, the corresponding argument can be any pointer expression. If the union member type is a pointer, qualifiers like @code{const} on the referenced type must be respected, just as with normal pointer conversions. Second, the argument is passed to the function using the calling conventions of the first member of the transparent union, not the calling conventions of the union itself. All members of the union must have the same machine representation; this is necessary for this argument passing to work properly. Transparent unions are designed for library functions that have multiple interfaces for compatibility reasons. For example, suppose the @code{wait} function must accept either a value of type @code{int *} to comply with Posix, or a value of type @code{union wait *} to comply with the 4.1BSD interface. If @code{wait}'s parameter were @code{void *}, @code{wait} would accept both kinds of arguments, but it would also accept any other pointer type and this would make argument type checking less useful. Instead, @code{} might define the interface as follows: @smallexample typedef union @{ int *__ip; union wait *__up; @} wait_status_ptr_t __attribute__ ((__transparent_union__)); pid_t wait (wait_status_ptr_t); @end smallexample This interface allows either @code{int *} or @code{union wait *} arguments to be passed, using the @code{int *} calling convention. The program can call @code{wait} with arguments of either type: @smallexample int w1 () @{ int w; return wait (&w); @} int w2 () @{ union wait w; return wait (&w); @} @end smallexample With this interface, @code{wait}'s implementation might look like this: @smallexample pid_t wait (wait_status_ptr_t p) @{ return waitpid (-1, p.__ip, 0); @} @end smallexample @item unused When attached to a type (including a @code{union} or a @code{struct}), this attribute means that variables of that type are meant to appear possibly unused. GCC will not produce a warning for any variables of that type, even if the variable appears to do nothing. This is often the case with lock or thread classes, which are usually defined and then not referenced, but contain constructors and destructors that have nontrivial bookkeeping functions. @item deprecated The @code{deprecated} attribute results in a warning if the type is used anywhere in the source file. This is useful when identifying types that are expected to be removed in a future version of a program. If possible, the warning also includes the location of the declaration of the deprecated type, to enable users to easily find further information about why the type is deprecated, or what they should do instead. Note that the warnings only occur for uses and then only if the type is being applied to an identifier that itself is not being declared as deprecated. @smallexample typedef int T1 __attribute__ ((deprecated)); T1 x; typedef T1 T2; T2 y; typedef T1 T3 __attribute__ ((deprecated)); T3 z __attribute__ ((deprecated)); @end smallexample results in a warning on line 2 and 3 but not lines 4, 5, or 6. No warning is issued for line 4 because T2 is not explicitly deprecated. Line 5 has no warning because T3 is explicitly deprecated. Similarly for line 6. The @code{deprecated} attribute can also be used for functions and variables (@pxref{Function Attributes}, @pxref{Variable Attributes}.) @item may_alias Accesses to objects with types with this attribute are not subjected to type-based alias analysis, but are instead assumed to be able to alias any other type of objects, just like the @code{char} type. See @option{-fstrict-aliasing} for more information on aliasing issues. Example of use: @smallexample typedef short __attribute__((__may_alias__)) short_a; int main (void) @{ int a = 0x12345678; short_a *b = (short_a *) &a; b[1] = 0; if (a == 0x12345678) abort(); exit(0); @} @end smallexample If you replaced @code{short_a} with @code{short} in the variable declaration, the above program would abort when compiled with @option{-fstrict-aliasing}, which is on by default at @option{-O2} or above in recent GCC versions. @item visibility In C++, attribute visibility (@pxref{Function Attributes}) can also be applied to class, struct, union and enum types. Unlike other type attributes, the attribute must appear between the initial keyword and the name of the type; it cannot appear after the body of the type. Note that the type visibility is applied to vague linkage entities associated with the class (vtable, typeinfo node, etc.). In particular, if a class is thrown as an exception in one shared object and caught in another, the class must have default visibility. Otherwise the two shared objects will be unable to use the same typeinfo node and exception handling will break. @subsection ARM Type Attributes On those ARM targets that support @code{dllimport} (such as Symbian OS), you can use the @code{notshared} attribute to indicate that the virtual table and other similar data for a class should not be exported from a DLL@. For example: @smallexample class __declspec(notshared) C @{ public: __declspec(dllimport) C(); virtual void f(); @} __declspec(dllexport) C::C() @{@} @end smallexample In this code, @code{C::C} is exported from the current DLL, but the virtual table for @code{C} is not exported. (You can use @code{__attribute__} instead of @code{__declspec} if you prefer, but most Symbian OS code uses @code{__declspec}.) @anchor{i386 Type Attributes} @subsection i386 Type Attributes Two attributes are currently defined for i386 configurations: @code{ms_struct} and @code{gcc_struct} @item ms_struct @itemx gcc_struct @cindex @code{ms_struct} @cindex @code{gcc_struct} If @code{packed} is used on a structure, or if bit-fields are used it may be that the Microsoft ABI packs them differently than GCC would normally pack them.

For full documentation of the struct attributes please see the documentation in the @xref{i386 Type Attributes}, section. The @code{altivec} attribute allows one to declare AltiVec vector data types supported by the AltiVec Programming Interface Manual. The attribute requires an argument to specify one of three vector types: @code{vector__}, @code{pixel__} (always followed by unsigned short), and @code{bool__} (always followed by unsigned). @smallexample __attribute__((altivec(vector__))) __attribute__((altivec(pixel__))) unsigned short __attribute__((altivec(bool__))) unsigned @end smallexample These attributes mainly are intended to support the @code{__vector}, @code{__pixel}, and @code{__bool} AltiVec keywords. @node Inline @section An Inline Function is As Fast As a Macro @cindex inline functions @cindex integrating function code @cindex open coding @cindex macros, inline alternative By declaring a function inline, you can direct GCC to make calls to that function faster. One way GCC can achieve this is to integrate that function's code into the code for its callers. This makes execution faster by eliminating the function-call overhead; in addition, if any of the actual argument values are constant, their known values may permit simplifications at compile time so that not all of the inline function's code needs to be included. The effect on code size is less predictable; object code may be larger or smaller with function inlining, depending on the particular case. You can also direct GCC to try to integrate all ``simple enough'' functions into their callers with the option @option{-finline-functions}. GCC implements three different semantics of declaring a function inline. One is available with @option{-std=gnu89}, another when @option{-std=c99} or @option{-std=gnu99}, and the third is used when compiling C++. To declare a function inline, use the @code{inline} keyword in its declaration, like this: @smallexample static inline int inc (int *a) @{ (*a)++; @} @end smallexample If you are writing a header file to be included in ISO C89 programs, write @code{__inline__} instead of @code{inline}. @xref{Alternate Keywords}. The three types of inlining behave similarly in two important cases: when the @code{inline} keyword is used on a @code{static} function, like the example above, and when a function is first declared without using the @code{inline} keyword and then is defined with @code{inline}, like this: @smallexample extern int inc (int *a); inline int inc (int *a) @{ (*a)++; @} @end smallexample In both of these common cases, the program behaves the same as if you had not used the @code{inline} keyword, except for its speed. @cindex inline functions, omission of @opindex fkeep-inline-functions When a function is both inline and @code{static}, if all calls to the function are integrated into the caller, and the function's address is never used, then the function's own assembler code is never referenced. In this case, GCC does not actually output assembler code for the function, unless you specify the option @option{-fkeep-inline-functions}. Some calls cannot be integrated for various reasons (in particular, calls that precede the function's definition cannot be integrated, and neither can recursive calls within the definition). If there is a nonintegrated call, then the function is compiled to assembler code as usual. The function must also be compiled as usual if the program refers to its address, because that can't be inlined. @cindex automatic @code{inline} for C++ member fns @cindex @code{inline} automatic for C++ member fns @cindex member fns, automatically @code{inline} @cindex C++ member fns, automatically @code{inline} @opindex fno-default-inline As required by ISO C++, GCC considers member functions defined within the body of a class to be marked inline even if they are not explicitly declared with the @code{inline} keyword. You can override this with @option{-fno-default-inline}; @pxref{C++ Dialect Options,,Options Controlling C++ Dialect}. GCC does not inline any functions when not optimizing unless you specify the @samp{always_inline} attribute for the function, like this: @smallexample /* @r{Prototype.} */ inline void foo (const char) __attribute__((always_inline)); @end smallexample The remainder of this section is specific to GNU C89 inlining. @cindex non-static inline function When an inline function is not @code{static}, then the compiler must assume that there may be calls from other source files; since a global symbol can be defined only once in any program, the function must not be defined in the other source files, so the calls therein cannot be integrated. Therefore, a non-@code{static} inline function is always compiled on its own in the usual fashion. If you specify both @code{inline} and @code{extern} in the function definition, then the definition is used only for inlining. In no case is the function compiled on its own, not even if you refer to its address explicitly. Such an address becomes an external reference, as if you had only declared the function, and had not defined it. This combination of @code{inline} and @code{extern} has almost the effect of a macro. The way to use it is to put a function definition in a header file with these keywords, and put another copy of the definition (lacking @code{inline} and @code{extern}) in a library file. The definition in the header file will cause most calls to the function to be inlined. If any uses of the function remain, they will refer to the single copy in the library. @node Extended Asm @section Assembler Instructions with C Expression Operands @cindex extended @code{asm} @cindex @code{asm} expressions @cindex assembler instructions @cindex registers In an assembler instruction using @code{asm}, you can specify the operands of the instruction using C expressions. This means you need not guess which registers or memory locations will contain the data you want to use. You must specify an assembler instruction template much like what appears in a machine description, plus an operand constraint string for each operand. For example, here is how to use the 68881's @code{fsinx} instruction: @smallexample asm ("fsinx %1,%0" : "=f" (result) : "f" (angle)); @end smallexample @noindent Here @code{angle} is the C expression for the input operand while @code{result} is that of the output operand. Each has @samp{"f"} as its operand constraint, saying that a floating point register is required. The @samp{=} in @samp{=f} indicates that the operand is an output; all output operands' constraints must use @samp{=}. The constraints use the same language used in the machine description (@pxref{Constraints}). Each operand is described by an operand-constraint string followed by the C expression in parentheses. A colon separates the assembler template from the first output operand and another separates the last output operand from the first input, if any. Commas separate the operands within each group. The total number of operands is currently limited to 30; this limitation may be lifted in some future version of GCC@. If there are no output operands but there are input operands, you must place two consecutive colons surrounding the place where the output operands would go. As of GCC version 3.1, it is also possible to specify input and output operands using symbolic names which can be referenced within the assembler code. These names are specified inside square brackets preceding the constraint string, and can be referenced inside the assembler code using @code{%[@var{name}]} instead of a percentage sign followed by the operand number. Using named operands the above example could look like: @smallexample asm ("fsinx %[angle],%[output]" : [output] "=f" (result) : [angle] "f" (angle)); @end smallexample @noindent Note that the symbolic operand names have no relation whatsoever to other C identifiers. You may use any name you like, even those of existing C symbols, but you must ensure that no two operands within the same assembler construct use the same symbolic name. Output operand expressions must be lvalues; the compiler can check this. The input operands need not be lvalues. The compiler cannot check whether the operands have data types that are reasonable for the instruction being executed. It does not parse the assembler instruction template and does not know what it means or even whether it is valid assembler input. The extended @code{asm} feature is most often used for machine instructions the compiler itself does not know exist. If the output expression cannot be directly addressed (for example, it is a bit-field), your constraint must allow a register. In that case, GCC will use the register as the output of the @code{asm}, and then store that register into the output. The ordinary output operands must be write-only; GCC will assume that the values in these operands before the instruction are dead and need not be generated. Extended asm supports input-output or read-write operands. Use the constraint character @samp{+} to indicate such an operand and list it with the output operands. You should only use read-write operands when the constraints for the operand (or the operand in which only some of the bits are to be changed) allow a register. You may, as an alternative, logically split its function into two separate operands, one input operand and one write-only output operand. The connection between them is expressed by constraints which say they need to be in the same location when the instruction executes. You can use the same C expression for both operands, or different expressions. For example, here we write the (fictitious) @samp{combine} instruction with @code{bar} as its read-only source operand and @code{foo} as its read-write destination: @smallexample asm ("combine %2,%0" : "=r" (foo) : "0" (foo), "g" (bar)); @end smallexample @noindent The constraint @samp{"0"} for operand 1 says that it must occupy the same location as operand 0. A number in constraint is allowed only in an input operand and it must refer to an output operand. Only a number in the constraint can guarantee that one operand will be in the same place as another. The mere fact that @code{foo} is the value of both operands is not enough to guarantee that they will be in the same place in the generated assembler code. The following would not work reliably: @smallexample asm ("combine %2,%0" : "=r" (foo) : "r" (foo), "g" (bar)); @end smallexample Various optimizations or reloading could cause operands 0 and 1 to be in different registers; GCC knows no reason not to do so. For example, the compiler might find a copy of the value of @code{foo} in one register and use it for operand 1, but generate the output operand 0 in a different register (copying it afterward to @code{foo}'s own address). Of course, since the register for operand 1 is not even mentioned in the assembler code, the result will not work, but GCC can't tell that. As of GCC version 3.1, one may write @code{[@var{name}]} instead of the operand number for a matching constraint. For example: @smallexample asm ("cmoveq %1,%2,%[result]" : [result] "=r"(result) : "r" (test), "r"(new), "[result]"(old)); @end smallexample Sometimes you need to make an @code{asm} operand be a specific register, but there's no matching constraint letter for that register @emph{by itself}. To force the operand into that register, use a local variable for the operand and specify the register in the variable declaration. @xref{Explicit Reg Vars}. Then for the @code{asm} operand, use any register constraint letter that matches the register: @smallexample register int *p1 asm ("r0") = @dots{}; register int *p2 asm ("r1") = @dots{}; register int *result asm ("r0"); asm ("sysint" : "=r" (result) : "0" (p1), "r" (p2)); @end smallexample @anchor{Example of asm with clobbered asm reg} In the above example, beware that a register that is call-clobbered by the target ABI will be overwritten by any function call in the assignment, including library calls for arithmetic operators. Assuming it is a call-clobbered register, this may happen to @code{r0} above by the assignment to @code{p2}. If you have to use such a register, use temporary variables for expressions between the register assignment and use: @smallexample int t1 = @dots{}; register int *p1 asm ("r0") = @dots{}; register int *p2 asm ("r1") = t1; register int *result asm ("r0"); asm ("sysint" : "=r" (result) : "0" (p1), "r" (p2)); @end smallexample Some instructions clobber specific hard registers. To describe this, write a third colon after the input operands, followed by the names of the clobbered hard registers (given as strings). Here is a realistic example for the VAX: @smallexample asm volatile ("movc3 %0,%1,%2" : /* @r{no outputs} */ : "g" (from), "g" (to), "g" (count) : "r0", "r1", "r2", "r3", "r4", "r5"); @end smallexample You may not write a clobber description in a way that overlaps with an input or output operand. For example, you may not have an operand describing a register class with one member if you mention that register in the clobber list. Variables declared to live in specific registers (@pxref{Explicit Reg Vars}), and used as asm input or output operands must have no part mentioned in the clobber description. There is no way for you to specify that an input operand is modified without also specifying it as an output operand. Note that if all the output operands you specify are for this purpose (and hence unused), you will then also need to specify @code{volatile} for the @code{asm} construct, as described below, to prevent GCC from deleting the @code{asm} statement as unused. If you refer to a particular hardware register from the assembler code, you will probably have to list the register after the third colon to tell the compiler the register's value is modified. In some assemblers, the register names begin with @samp{%}; to produce one @samp{%} in the assembler code, you must write @samp{%%} in the input. If your assembler instruction can alter the condition code register, add @samp{cc} to the list of clobbered registers. GCC on some machines represents the condition codes as a specific hardware register; @samp{cc} serves to name this register. On other machines, the condition code is handled differently, and specifying @samp{cc} has no effect. But it is valid no matter what the machine. If your assembler instructions access memory in an unpredictable fashion, add @samp{memory} to the list of clobbered registers. This will cause GCC to not keep memory values cached in registers across the assembler instruction and not optimize stores or loads to that memory. You will also want to add the @code{volatile} keyword if the memory affected is not listed in the inputs or outputs of the @code{asm}, as the @samp{memory} clobber does not count as a side-effect of the @code{asm}. If you know how large the accessed memory is, you can add it as input or output but if this is not known, you should add @samp{memory}. As an example, if you access ten bytes of a string, you can use a memory input like: @smallexample @{"m"( (@{ struct @{ char x[10]; @} *p = (void *)ptr ; *p; @}) )@}. @end smallexample Note that in the following example the memory input is necessary, otherwise GCC might optimize the store to @code{x} away: @smallexample int foo () @{ int x = 42; int *y = &x; int result; asm ("magic stuff accessing an 'int' pointed to by '%1'" "=&d" (r) : "a" (y), "m" (*y)); return result; @} @end smallexample You can put multiple assembler instructions together in a single @code{asm} template, separated by the characters normally used in assembly code for the system. A combination that works in most places is a newline to break the line, plus a tab character to move to the instruction field (written as @samp{\n\t}). Sometimes semicolons can be used, if the assembler allows semicolons as a line-breaking character. Note that some assembler dialects use semicolons to start a comment. The input operands are guaranteed not to use any of the clobbered registers, and neither will the output operands' addresses, so you can read and write the clobbered registers as many times as you like. Here is an example of multiple instructions in a template; it assumes the subroutine @code{_foo} accepts arguments in registers 9 and 10: @smallexample asm ("movl %0,r9\n\tmovl %1,r10\n\tcall _foo" : /* no outputs */ : "g" (from), "g" (to) : "r9", "r10"); @end smallexample Unless an output operand has the @samp{&} constraint modifier, GCC may allocate it in the same register as an unrelated input operand, on the assumption the inputs are consumed before the outputs are produced. This assumption may be false if the assembler code actually consists of more than one instruction. In such a case, use @samp{&} for each output operand that may not overlap an input. @xref{Modifiers}. If you want to test the condition code produced by an assembler instruction, you must include a branch and a label in the @code{asm} construct, as follows: @smallexample asm ("clr %0\n\tfrob %1\n\tbeq 0f\n\tmov #1,%0\n0:" : "g" (result) : "g" (input)); @end smallexample @noindent This assumes your assembler supports local labels, as the GNU assembler and most Unix assemblers do. Speaking of labels, jumps from one @code{asm} to another are not supported. The compiler's optimizers do not know about these jumps, and therefore they cannot take account of them when deciding how to optimize. @cindex macros containing @code{asm} Usually the most convenient way to use these @code{asm} instructions is to encapsulate them in macros that look like functions. For example, @smallexample #define sin(x) \ (@{ double __value, __arg = (x); \ asm ("fsinx %1,%0": "=f" (__value): "f" (__arg)); \ __value; @}) @end smallexample @noindent Here the variable @code{__arg} is used to make sure that the instruction operates on a proper @code{double} value, and to accept only those arguments @code{x} which can convert automatically to a @code{double}. Another way to make sure the instruction operates on the correct data type is to use a cast in the @code{asm}. This is different from using a variable @code{__arg} in that it converts more different types. For example, if the desired type were @code{int}, casting the argument to @code{int} would accept a pointer with no complaint, while assigning the argument to an @code{int} variable named @code{__arg} would warn about using a pointer unless the caller explicitly casts it. If an @code{asm} has output operands, GCC assumes for optimization purposes the instruction has no side effects except to change the output operands. This does not mean instructions with a side effect cannot be used, but you must be careful, because the compiler may eliminate them if the output operands aren't used, or move them out of loops, or replace two with one if they constitute a common subexpression. Also, if your instruction does have a side effect on a variable that otherwise appears not to change, the old value of the variable may be reused later if it happens to be found in a register. You can prevent an @code{asm} instruction from being deleted by writing the keyword @code{volatile} after the @code{asm}. For example: @smallexample #define get_and_set_priority(new) \ (@{ int __old; \ asm volatile ("get_and_set_priority %0, %1" \ : "=g" (__old) : "g" (new)); \ __old; @}) @end smallexample @noindent The @code{volatile} keyword indicates that the instruction has important side-effects. GCC will not delete a volatile @code{asm} if it is reachable. (The instruction can still be deleted if GCC can prove that control-flow will never reach the location of the instruction.) Note that even a volatile @code{asm} instruction can be moved relative to other code, including across jump instructions. For example, on many targets there is a system register which can be set to control the rounding mode of floating point operations. You might try setting it with a volatile @code{asm}, like this PowerPC example: @smallexample asm volatile("mtfsf 255,%0" : : "f" (fpenv)); sum = x + y; @end smallexample @noindent This will not work reliably, as the compiler may move the addition back before the volatile @code{asm}. To make it work you need to add an artificial dependency to the @code{asm} referencing a variable in the code you don't want moved, for example: @smallexample asm volatile ("mtfsf 255,%1" : "=X"(sum): "f"(fpenv)); sum = x + y; @end smallexample Similarly, you can't expect a sequence of volatile @code{asm} instructions to remain perfectly consecutive. If you want consecutive output, use a single @code{asm}. Also, GCC will perform some optimizations across a volatile @code{asm} instruction; GCC does not ``forget everything'' when it encounters a volatile @code{asm} instruction the way some other compilers do. An @code{asm} instruction without any output operands will be treated identically to a volatile @code{asm} instruction. It is a natural idea to look for a way to give access to the condition code left by the assembler instruction. However, when we attempted to implement this, we found no way to make it work reliably. The problem is that output operands might need reloading, which would result in additional following ``store'' instructions. On most machines, these instructions would alter the condition code before there was time to test it. This problem doesn't arise for ordinary ``test'' and ``compare'' instructions because they don't have any output operands. For reasons similar to those described above, it is not possible to give an assembler instruction access to the condition code left by previous instructions. If you are writing a header file that should be includable in ISO C programs, write @code{__asm__} instead of @code{asm}. @xref{Alternate Keywords}. @subsection Size of an @code{asm} Some targets require that GCC track the size of each instruction used in order to generate correct code. Because the final length of an @code{asm} is only known by the assembler, GCC must make an estimate as to how big it will be. The estimate is formed by counting the number of statements in the pattern of the @code{asm} and multiplying that by the length of the longest instruction on that processor. Statements in the @code{asm} are identified by newline characters and whatever statement separator characters are supported by the assembler; on most processors this is the `@code{;}' character. Normally, GCC's estimate is perfectly adequate to ensure that correct code is generated, but it is possible to confuse the compiler if you use pseudo instructions or assembler macros that expand into multiple real instructions or if you use assembler directives that expand to more space in the object file than would be needed for a single instruction. If this happens then the assembler will produce a diagnostic saying that a label is unreachable. @subsection i386 floating point asm operands There are several rules on the usage of stack-like regs in asm_operands insns. These rules apply only to the operands that are stack-like regs: @enumerate @item Given a set of input regs that die in an asm_operands, it is necessary to know which are implicitly popped by the asm, and which must be explicitly popped by gcc. An input reg that is implicitly popped by the asm must be explicitly clobbered, unless it is constrained to match an output operand. @item For any input reg that is implicitly popped by an asm, it is necessary to know how to adjust the stack to compensate for the pop. If any non-popped input is closer to the top of the reg-stack than the implicitly popped reg, it would not be possible to know what the stack looked like---it's not clear how the rest of the stack ``slides up''. All implicitly popped input regs must be closer to the top of the reg-stack than any input that is not implicitly popped. It is possible that if an input dies in an insn, reload might use the input reg for an output reload. Consider this example: @smallexample asm ("foo" : "=t" (a) : "f" (b)); @end smallexample This asm says that input B is not popped by the asm, and that the asm pushes a result onto the reg-stack, i.e., the stack is one deeper after the asm than it was before. But, it is possible that reload will think that it can use the same reg for both the input and the output, if input B dies in this insn. If any input operand uses the @code{f} constraint, all output reg constraints must use the @code{&} earlyclobber. The asm above would be written as @smallexample asm ("foo" : "=&t" (a) : "f" (b)); @end smallexample @item Some operands need to be in particular places on the stack. All output operands fall in this category---there is no other way to know which regs the outputs appear in unless the user indicates this in the constraints. Output operands must specifically indicate which reg an output appears in after an asm. @code{=f} is not allowed: the operand constraints must select a class with a single reg. @item Output operands may not be ``inserted'' between existing stack regs. Since no 387 opcode uses a read/write operand, all output operands are dead before the asm_operands, and are pushed by the asm_operands. It makes no sense to push anywhere but the top of the reg-stack. Output operands must start at the top of the reg-stack: output operands may not ``skip'' a reg. @item Some asm statements may need extra stack space for internal calculations. This can be guaranteed by clobbering stack registers unrelated to the inputs and outputs. @end enumerate Here are a couple of reasonable asms to want to write. This asm takes one input, which is internally popped, and produces two outputs. @smallexample asm ("fsincos" : "=t" (cos), "=u" (sin) : "0" (inp)); @end smallexample This asm takes two inputs, which are popped by the @code{fyl2xp1} opcode, and replaces them with one output. The user must code the @code{st(1)} clobber for reg-stack.c to know that @code{fyl2xp1} pops both inputs. @smallexample asm ("fyl2xp1" : "=t" (result) : "0" (x), "u" (y) : "st(1)"); @end smallexample @include md.texi @node Asm Labels @section Controlling Names Used in Assembler Code @cindex assembler names for identifiers @cindex names used in assembler code @cindex identifiers, names in assembler code You can specify the name to be used in the assembler code for a C function or variable by writing the @code{asm} (or @code{__asm__}) keyword after the declarator as follows: @smallexample int foo asm ("myfoo") = 2; @end smallexample @noindent This specifies that the name to be used for the variable @code{foo} in the assembler code should be @samp{myfoo} rather than the usual @samp{_foo}. On systems where an underscore is normally prepended to the name of a C function or variable, this feature allows you to define names for the linker that do not start with an underscore. It does not make sense to use this feature with a non-static local variable since such variables do not have assembler names. If you are trying to put the variable in a particular register, see @ref{Explicit Reg Vars}. GCC presently accepts such code with a warning, but will probably be changed to issue an error, rather than a warning, in the future. You cannot use @code{asm} in this way in a function @emph{definition}; but you can get the same effect by writing a declaration for the function before its definition and putting @code{asm} there, like this: @smallexample extern func () asm ("FUNC"); func (x, y) int x, y; /* @r{@dots{}} */ @end smallexample It is up to you to make sure that the assembler names you choose do not conflict with any other assembler symbols. Also, you must not use a register name; that would produce completely invalid assembler code. GCC does not as yet have the ability to store static variables in registers. Perhaps that will be added. @node Explicit Reg Vars @section Variables in Specified Registers @cindex explicit register variables @cindex variables in specified registers @cindex specified registers @cindex registers, global allocation GNU C allows you to put a few global variables into specified hardware registers. You can also specify the register in which an ordinary register variable should be allocated. @itemize @bullet @item Global register variables reserve registers throughout the program. This may be useful in programs such as programming language interpreters which have a couple of global variables that are accessed very often. @item Local register variables in specific registers do not reserve the registers, except at the point where they are used as input or output operands in an @code{asm} statement and the @code{asm} statement itself is not deleted. The compiler's data flow analysis is capable of determining where the specified registers contain live values, and where they are available for other uses. Stores into local register variables may be deleted when they appear to be dead according to dataflow analysis. References to local register variables may be deleted or moved or simplified. These local variables are sometimes convenient for use with the extended @code{asm} feature (@pxref{Extended Asm}), if you want to write one output of the assembler instruction directly into a particular register. (This will work provided the register you specify fits the constraints specified for that operand in the @code{asm}.) @end itemize @menu * Global Reg Vars:: * Local Reg Vars:: @end menu @node Global Reg Vars @subsection Defining Global Register Variables @cindex global register variables @cindex registers, global variables in You can define a global register variable in GNU C like this: @smallexample register int *foo asm ("a5"); @end smallexample @noindent Here @code{a5} is the name of the register which should be used. Choose a register which is normally saved and restored by function calls on your machine, so that library routines will not clobber it. Naturally the register name is cpu-dependent, so you would need to conditionalize your program according to cpu type. The register @code{a5} would be a good choice on a 68000 for a variable of pointer type. On machines with register windows, be sure to choose a ``global'' register that is not affected magically by the function call mechanism. In addition, operating systems on one type of cpu may differ in how they name the registers; then you would need additional conditionals. For example, some 68000 operating systems call this register @code{%a5}. Eventually there may be a way of asking the compiler to choose a register automatically, but first we need to figure out how it should choose and how to enable you to guide the choice. No solution is evident. Defining a global register variable in a certain register reserves that register entirely for this use, at least within the current compilation. The register will not be allocated for any other purpose in the functions in the current compilation. The register will not be saved and restored by these functions. Stores into this register are never deleted even if they would appear to be dead, but references may be deleted or moved or simplified. It is not safe to access the global register variables from signal handlers, or from more than one thread of control, because the system library routines may temporarily use the register for other things (unless you recompile them specially for the task at hand). @cindex @code{qsort}, and global register variables It is not safe for one function that uses a global register variable to call another such function @code{foo} by way of a third function @code{lose} that was compiled without knowledge of this variable (i.e.@: in a different source file in which the variable wasn't declared). This is because @code{lose} might save the register and put some other value there. For example, you can't expect a global register variable to be available in the comparison-function that you pass to @code{qsort}, since @code{qsort} might have put something else in that register. (If you are prepared to recompile @code{qsort} with the same global register variable, you can solve this problem.) If you want to recompile @code{qsort} or other source files which do not actually use your global register variable, so that they will not use that register for any other purpose, then it suffices to specify the compiler option @option{-ffixed-@var{reg}}. You need not actually add a global register declaration to their source code. A function which can alter the value of a global register variable cannot safely be called from a function compiled without this variable, because it could clobber the value the caller expects to find there on return. Therefore, the function which is the entry point into the part of the program that uses the global register variable must explicitly save and restore the value which belongs to its caller. @cindex register variable after @code{longjmp} @cindex global register after @code{longjmp} @cindex value after @code{longjmp} @findex longjmp @findex setjmp On most machines, @code{longjmp} will restore to each global register variable the value it had at the time of the @code{setjmp}. On some machines, however, @code{longjmp} will not change the value of global register variables. To be portable, the function that called @code{setjmp} should make other arrangements to save the values of the global register variables, and to restore them in a @code{longjmp}. This way, the same thing will happen regardless of what @code{longjmp} does. All global register variable declarations must precede all function definitions. If such a declaration could appear after function definitions, the declaration would be too late to prevent the register from being used for other purposes in the preceding functions. Global register variables may not have initial values, because an executable file has no means to supply initial contents for a register. On the SPARC, there are reports that g3 @dots{} g7 are suitable registers, but certain library functions, such as @code{getwd}, as well as the subroutines for division and remainder, modify g3 and g4. g1 and g2 are local temporaries. On the 68000, a2 @dots{} a5 should be suitable, as should d2 @dots{} d7. Of course, it will not do to use more than a few of those. @node Local Reg Vars @subsection Specifying Registers for Local Variables @cindex local variables, specifying registers @cindex specifying registers for local variables @cindex registers for local variables You can define a local register variable with a specified register like this: @smallexample register int *foo asm ("a5"); @end smallexample @noindent Here @code{a5} is the name of the register which should be used. Note that this is the same syntax used for defining global register variables, but for a local variable it would appear within a function. Naturally the register name is cpu-dependent, but this is not a problem, since specific registers are most often useful with explicit assembler instructions (@pxref{Extended Asm}). Both of these things generally require that you conditionalize your program according to cpu type. In addition, operating systems on one type of cpu may differ in how they name the registers; then you would need additional conditionals. For example, some 68000 operating systems call this register @code{%a5}. Defining such a register variable does not reserve the register; it remains available for other uses in places where flow control determines the variable's value is not live. This option does not guarantee that GCC will generate code that has this variable in the register you specify at all times. You may not code an explicit reference to this register in the @emph{assembler instruction template} part of an @code{asm} statement and assume it will always refer to this variable. However, using the variable as an @code{asm} @emph{operand} guarantees that the specified register is used for the operand. Stores into local register variables may be deleted when they appear to be dead according to dataflow analysis. References to local register variables may be deleted or moved or simplified. As for global register variables, it's recommended that you choose a register which is normally saved and restored by function calls on your machine, so that library routines will not clobber it. A common pitfall is to initialize multiple call-clobbered registers with arbitrary expressions, where a function call or library call for an arithmetic operator will overwrite a register value from a previous assignment, for example @code{r0} below: @smallexample register int *p1 asm ("r0") = @dots{}; register int *p2 asm ("r1") = @dots{}; @end smallexample In those cases, a solution is to use a temporary variable for each arbitrary expression. @xref{Example of asm with clobbered asm reg}. @node Alternate Keywords @section Alternate Keywords @cindex alternate keywords @cindex keywords, alternate @option{-ansi} and the various @option{-std} options disable certain keywords. This causes trouble when you want to use GNU C extensions, or a general-purpose header file that should be usable by all programs, including ISO C programs. The keywords @code{asm}, @code{typeof} and @code{inline} are not available in programs compiled with @option{-ansi} or @option{-std} (although @code{inline} can be used in a program compiled with @option{-std=c99}). The ISO C99 keyword @code{restrict} is only available when @option{-std=gnu99} (which will eventually be the default) or @option{-std=c99} (or the equivalent @option{-std=iso9899:1999}) is used. The way to solve these problems is to put @samp{__} at the beginning and end of each problematical keyword. For example, use @code{__asm__} instead of @code{asm}, and @code{__inline__} instead of @code{inline}. Other C compilers won't accept these alternative keywords; if you want to compile with another compiler, you can define the alternate keywords as macros to replace them with the customary keywords. It looks like this: @smallexample #ifndef __GNUC__ #define __asm__ asm #endif @end smallexample @findex __extension__ @opindex pedantic @option{-pedantic} and other options cause warnings for many GNU C extensions. You can prevent such warnings within one expression by writing @code{__extension__} before the expression. @code{__extension__} has no effect aside from this. @node Incomplete Enums @section Incomplete @code{enum} Types You can define an @code{enum} tag without specifying its possible values. This results in an incomplete type, much like what you get if you write @code{struct foo} without describing the elements. A later declaration which does specify the possible values completes the type. You can't allocate variables or storage using the type while it is incomplete. However, you can work with pointers to that type. This extension may not be very useful, but it makes the handling of @code{enum} more consistent with the way @code{struct} and @code{union} are handled. This extension is not supported by GNU C++. @node Function Names @section Function Names as Strings @cindex @code{__func__} identifier @cindex @code{__FUNCTION__} identifier @cindex @code{__PRETTY_FUNCTION__} identifier GCC provides three magic variables which hold the name of the current function, as a string. The first of these is @code{__func__}, which is part of the C99 standard: @display The identifier @code{__func__} is implicitly declared by the translator as if, immediately following the opening brace of each function definition, the declaration @smallexample static const char __func__[] = "function-name"; @end smallexample appeared, where function-name is the name of the lexically-enclosing function. This name is the unadorned name of the function. @end display @code{__FUNCTION__} is another name for @code{__func__}. Older versions of GCC recognize only this name. However, it is not standardized. For maximum portability, we recommend you use @code{__func__}, but provide a fallback definition with the preprocessor: @smallexample #if __STDC_VERSION__ < 199901L # if __GNUC__ >= 2 # define __func__ __FUNCTION__ # else # define __func__ "" # endif #endif @end smallexample In C, @code{__PRETTY_FUNCTION__} is yet another name for @code{__func__}. However, in C++, @code{__PRETTY_FUNCTION__} contains the type signature of the function as well as its bare name. For example, this program: @smallexample extern "C" @{ extern int printf (char *, ...); @} class a @{ public: void sub (int i) @{ printf ("__FUNCTION__ = %s\n", __FUNCTION__); printf ("__PRETTY_FUNCTION__ = %s\n", __PRETTY_FUNCTION__); @} @}; int main (void) @{ a ax; ax.sub (0); return 0; @} @end smallexample @noindent gives this output: @smallexample __FUNCTION__ = sub __PRETTY_FUNCTION__ = void a::sub(int) @end smallexample These identifiers are not preprocessor macros. In GCC 3.3 and earlier, in C only, @code{__FUNCTION__} and @code{__PRETTY_FUNCTION__} were treated as string literals; they could be used to initialize @code{char} arrays, and they could be concatenated with other string literals. GCC 3.4 and later treat them as variables, like @code{__func__}. In C++, @code{__FUNCTION__} and @code{__PRETTY_FUNCTION__} have always been variables. @node Return Address @section Getting the Return or Frame Address of a Function These functions may be used to get information about the callers of a function. @deftypefn {Built-in Function} {void *} __builtin_return_address (unsigned int @var{level}) This function returns the return address of the current function, or of one of its callers. The @var{level} argument is number of frames to scan up the call stack. A value of @code{0} yields the return address of the current function, a value of @code{1} yields the return address of the caller of the current function, and so forth. When inlining the expected behavior is that the function will return the address of the function that will be returned to. To work around this behavior use the @code{noinline} function attribute. The @var{level} argument must be a constant integer. On some machines it may be impossible to determine the return address of any function other than the current one; in such cases, or when the top of the stack has been reached, this function will return @code{0} or a random value. In addition, @code{__builtin_frame_address} may be used to determine if the top of the stack has been reached. This function should only be used with a nonzero argument for debugging purposes. @end deftypefn @deftypefn {Built-in Function} {void *} __builtin_frame_address (unsigned int @var{level}) This function is similar to @code{__builtin_return_address}, but it returns the address of the function frame rather than the return address of the function. Calling @code{__builtin_frame_address} with a value of @code{0} yields the frame address of the current function, a value of @code{1} yields the frame address of the caller of the current function, and so forth. The frame is the area on the stack which holds local variables and saved registers. The frame address is normally the address of the first word pushed on to the stack by the function. However, the exact definition depends upon the processor and the calling convention. If the processor has a dedicated frame pointer register, and the function has a frame, then @code{__builtin_frame_address} will return the value of the frame pointer register. On some machines it may be impossible to determine the frame address of any function other than the current one; in such cases, or when the top of the stack has been reached, this function will return @code{0} if the first frame pointer is properly initialized by the startup code. This function should only be used with a nonzero argument for debugging purposes. @end deftypefn @node Vector Extensions @section Using vector instructions through built-in functions On some targets, the instruction set contains SIMD vector instructions that operate on multiple values contained in one large register at the same time. For example, on the i386 the MMX, 3Dnow! and SSE extensions can be used this way. The first step in using these extensions is to provide the necessary data types. This should be done using an appropriate @code{typedef}: @smallexample typedef int v4si __attribute__ ((vector_size (16))); @end smallexample The @code{int} type specifies the base type, while the attribute specifies the vector size for the variable, measured in bytes. For example, the declaration above causes the compiler to set the mode for the @code{v4si} type to be 16 bytes wide and divided into @code{int} sized units. For a 32-bit @code{int} this means a vector of 4 units of 4 bytes, and the corresponding mode of @code{foo} will be @acronym{V4SI}. The @code{vector_size} attribute is only applicable to integral and float scalars, although arrays, pointers, and function return values are allowed in conjunction with this construct. All the basic integer types can be used as base types, both as signed and as unsigned: @code{char}, @code{short}, @code{int}, @code{long}, @code{long long}. In addition, @code{float} and @code{double} can be used to build floating-point vector types. Specifying a combination that is not valid for the current architecture will cause GCC to synthesize the instructions using a narrower mode. For example, if you specify a variable of type @code{V4SI} and your architecture does not allow for this specific SIMD type, GCC will produce code that uses 4 @code{SIs}. The types defined in this manner can be used with a subset of normal C operations. Currently, GCC will allow using the following operators on these types: @code{+, -, *, /, unary minus, ^, |, &, ~}@. The operations behave like C++ @code{valarrays}. Addition is defined as the addition of the corresponding elements of the operands. For example, in the code below, each of the 4 elements in @var{a} will be added to the corresponding 4 elements in @var{b} and the resulting vector will be stored in @var{c}. @smallexample typedef int v4si __attribute__ ((vector_size (16))); v4si a, b, c; c = a + b; @end smallexample Subtraction, multiplication, division, and the logical operations operate in a similar manner. Likewise, the result of using the unary minus or complement operators on a vector type is a vector whose elements are the negative or complemented values of the corresponding elements in the operand. You can declare variables and use them in function calls and returns, as well as in assignments and some casts. You can specify a vector type as a return type for a function. Vector types can also be used as function arguments. It is possible to cast from one vector type to another, provided they are of the same size (in fact, you can also cast vectors to and from other datatypes of the same size). You cannot operate between vectors of different lengths or different signedness without a cast. A port that supports hardware vector operations, usually provides a set of built-in functions that can be used to operate on vectors. For example, a function to add two vectors and multiply the result by a third could look like this: @smallexample v4si f (v4si a, v4si b, v4si c) @{ v4si tmp = __builtin_addv4si (a, b); return __builtin_mulv4si (tmp, c); @} @end smallexample @node Offsetof @section Offsetof @findex __builtin_offsetof GCC implements for both C and C++ a syntactic extension to implement the @code{offsetof} macro. @smallexample primary: "__builtin_offsetof" "(" @code{typename} "," offsetof_member_designator ")" offsetof_member_designator: @code{identifier} | offsetof_member_designator "." @code{identifier} | offsetof_member_designator "[" @code{expr} "]" @end smallexample This extension is sufficient such that @smallexample #define offsetof(@var{type}, @var{member}) __builtin_offsetof (@var{type}, @var{member}) @end smallexample is a suitable definition of the @code{offsetof} macro. In C++, @var{type} may be dependent. In either case, @var{member} may consist of a single identifier, or a sequence of member accesses and array references. @node Atomic Builtins @section Built-in functions for atomic memory access The following builtins are intended to be compatible with those described in the @cite{Intel Itanium Processor-specific Application Binary Interface}, section 7.4. As such, they depart from the normal GCC practice of using the ``__builtin_'' prefix, and further that they are overloaded such that they work on multiple types. The definition given in the Intel documentation allows only for the use of the types @code{int}, @code{long}, @code{long long} as well as their unsigned counterparts. GCC will allow any integral scalar or pointer type that is 1, 2, 4 or 8 bytes in length. Not all operations are supported by all target processors. If a particular operation cannot be implemented on the target processor, a warning will be generated and a call an external function will be generated. The external function will carry the same name as the builtin, with an additional suffix @samp{_@var{n}} where @var{n} is the size of the data type. @c ??? Should we have a mechanism to suppress this warning? This is almost @c useful for implementing the operation under the control of an external @c mutex. In most cases, these builtins are considered a @dfn{full barrier}. That is, no memory operand will be moved across the operation, either forward or backward. Further, instructions will be issued as necessary to prevent the processor from speculating loads across the operation and from queuing stores after the operation. All of the routines are are described in the Intel documentation to take ``an optional list of variables protected by the memory barrier''. It's not clear what is meant by that; it could mean that @emph{only} the following variables are protected, or it could mean that these variables should in addition be protected. At present GCC ignores this list and protects all variables which are globally accessible. If in the future we make some use of this list, an empty list will continue to mean all globally accessible variables. @table @code @item @var{type} __sync_fetch_and_add (@var{type} *ptr, @var{type} value, ...) @itemx @var{type} __sync_fetch_and_sub (@var{type} *ptr, @var{type} value, ...) @itemx @var{type} __sync_fetch_and_or (@var{type} *ptr, @var{type} value, ...) @itemx @var{type} __sync_fetch_and_and (@var{type} *ptr, @var{type} value, ...) @itemx @var{type} __sync_fetch_and_xor (@var{type} *ptr, @var{type} value, ...) @itemx @var{type} __sync_fetch_and_nand (@var{type} *ptr, @var{type} value, ...) @findex __sync_fetch_and_add @findex __sync_fetch_and_sub @findex __sync_fetch_and_or @findex __sync_fetch_and_and @findex __sync_fetch_and_xor @findex __sync_fetch_and_nand These builtins perform the operation suggested by the name, and returns the value that had previously been in memory.

That is, if the current value of @code{*@var{ptr}} is @var{oldval}, then write @var{newval} into @code{*@var{ptr}}. The ``bool'' version returns true if the comparison is successful and @var{newval} was written. The ``val'' version returns the contents of @code{*@var{ptr}} before the operation. @item __sync_synchronize (...) @findex __sync_synchronize This builtin issues a full memory barrier. @item @var{type} __sync_lock_test_and_set (@var{type} *ptr, @var{type} value, ...) @findex __sync_lock_test_and_set This builtin, as described by Intel, is not a traditional test-and-set operation, but rather an atomic exchange operation. It writes @var{value} into @code{*@var{ptr}}, and returns the previous contents of @code{*@var{ptr}}. Many targets have only minimal support for such locks, and do not support a full exchange operation. In this case, a target may support reduced functionality here by which the @emph{only} valid value to store is the immediate constant 1. The exact value actually stored in @code{*@var{ptr}} is implementation defined. This builtin is not a full barrier, but rather an @dfn{acquire barrier}. This means that references after the builtin cannot move to (or be speculated to) before the builtin, but previous memory stores may not be globally visible yet, and previous memory loads may not yet be satisfied. @item void __sync_lock_release (@var{type} *ptr, ...) @findex __sync_lock_release This builtin releases the lock acquired by @code{__sync_lock_test_and_set}. Normally this means writing the constant 0 to @code{*@var{ptr}}. This builtin is not a full barrier, but rather a @dfn{release barrier}. This means that all previous memory stores are globally visible, and all previous memory loads have been satisfied, but following memory reads are not prevented from being speculated to before the barrier. @end table @node Object Size Checking @section Object Size Checking Builtins @findex __builtin_object_size @findex __builtin___memcpy_chk @findex __builtin___mempcpy_chk @findex __builtin___memmove_chk @findex __builtin___memset_chk @findex __builtin___strcpy_chk @findex __builtin___stpcpy_chk @findex __builtin___strncpy_chk @findex __builtin___strcat_chk @findex __builtin___strncat_chk @findex __builtin___sprintf_chk @findex __builtin___snprintf_chk @findex __builtin___vsprintf_chk @findex __builtin___vsnprintf_chk @findex __builtin___printf_chk @findex __builtin___vprintf_chk @findex __builtin___fprintf_chk @findex __builtin___vfprintf_chk GCC implements a limited buffer overflow protection mechanism that can prevent some buffer overflow attacks. @deftypefn {Built-in Function} {size_t} __builtin_object_size (void * @var{ptr}, int @var{type}) is a built-in construct that returns a constant number of bytes from @var{ptr} to the end of the object @var{ptr} pointer points to (if known at compile time). @code{__builtin_object_size} never evaluates its arguments for side-effects. If there are any side-effects in them, it returns @code{(size_t) -1} for @var{type} 0 or 1 and @code{(size_t) 0} for @var{type} 2 or 3. If there are multiple objects @var{ptr} can point to and all of them are known at compile time, the returned number is the maximum of remaining byte counts in those objects if @var{type} & 2 is 0 and minimum if nonzero. If it is not possible to determine which objects @var{ptr} points to at compile time, @code{__builtin_object_size} should return @code{(size_t) -1} for @var{type} 0 or 1 and @code{(size_t) 0} for @var{type} 2 or 3. @var{type} is an integer constant from 0 to 3. If the least significant bit is clear, objects are whole variables, if it is set, a closest surrounding subobject is considered the object a pointer points to. The second bit determines if maximum or minimum of remaining bytes is computed. @smallexample struct V @{ char buf1[10]; int b; char buf2[10]; @} var; char *p = &var.buf1[1], *q = &var.b; /* Here the object p points to is var. */ assert (__builtin_object_size (p, 0) == sizeof (var) - 1); /* The subobject p points to is var.buf1. */ assert (__builtin_object_size (p, 1) == sizeof (var.buf1) - 1); /* The object q points to is var. */ assert (__builtin_object_size (q, 0) == (char *) (&var + 1) - (char *) &var.b); /* The subobject q points to is var.b. */ assert (__builtin_object_size (q, 1) == sizeof (var.b)); @end smallexample @end deftypefn There are built-in functions added for many common string operation functions, e.g. for @code{memcpy} @code{__builtin___memcpy_chk} built-in is provided. This built-in has an additional last argument, which is the number of bytes remaining in object the @var{dest} argument points to or @code{(size_t) -1} if the size is not known. The built-in functions are optimized into the normal string functions like @code{memcpy} if the last argument is @code{(size_t) -1} or if it is known at compile time that the destination object will not be overflown. If the compiler can determine at compile time the object will be always overflown, it issues a warning. The intended use can be e.g. @smallexample #undef memcpy #define bos0(dest) __builtin_object_size (dest, 0) #define memcpy(dest, src, n) \ __builtin___memcpy_chk (dest, src, n, bos0 (dest)) char *volatile p; char buf[10]; /* It is unknown what object p points to, so this is optimized into plain memcpy - no checking is possible. */ memcpy (p, "abcde", n); /* Destination is known and length too. It is known at compile time there will be no overflow. */ memcpy (&buf[5], "abcde", 5); /* Destination is known, but the length is not known at compile time. This will result in __memcpy_chk call that can check for overflow at runtime. */ memcpy (&buf[5], "abcde", n); /* Destination is known and it is known at compile time there will be overflow. There will be a warning and __memcpy_chk call that will abort the program at runtime. */ memcpy (&buf[6], "abcde", 5); @end smallexample Such built-in functions are provided for @code{memcpy}, @code{mempcpy}, @code{memmove}, @code{memset}, @code{strcpy}, @code{stpcpy}, @code{strncpy}, @code{strcat} and @code{strncat}. There are also checking built-in functions for formatted output functions. @smallexample int __builtin___sprintf_chk (char *s, int flag, size_t os, const char *fmt, ...); int __builtin___snprintf_chk (char *s, size_t maxlen, int flag, size_t os, const char *fmt, ...); int __builtin___vsprintf_chk (char *s, int flag, size_t os, const char *fmt, va_list ap); int __builtin___vsnprintf_chk (char *s, size_t maxlen, int flag, size_t os, const char *fmt, va_list ap); @end smallexample The added @var{flag} argument is passed unchanged to @code{__sprintf_chk} etc. functions and can contain implementation specific flags on what additional security measures the checking function might take, such as handling @code{%n} differently. The @var{os} argument is the object size @var{s} points to, like in the other built-in functions. There is a small difference in the behavior though, if @var{os} is @code{(size_t) -1}, the built-in functions are optimized into the non-checking functions only if @var{flag} is 0, otherwise the checking function is called with @var{os} argument set to @code{(size_t) -1}. In addition to this, there are checking built-in functions @code{__builtin___printf_chk}, @code{__builtin___vprintf_chk}, @code{__builtin___fprintf_chk} and @code{__builtin___vfprintf_chk}. These have just one additional argument, @var{flag}, right before format string @var{fmt}. If the compiler is able to optimize them to @code{fputc} etc. functions, it will, otherwise the checking function should be called and the @var{flag} argument passed to it. @node Other Builtins

The remaining functions are provided for optimization purposes. @opindex fno-builtin GCC includes built-in versions of many of the functions in the standard C library. The versions prefixed with @code{__builtin_} will always be treated as having the same meaning as the C library function even if you specify the @option{-fno-builtin} option.

All these functions have corresponding versions prefixed with @code{__builtin_}.

All of these functions have corresponding versions prefixed with @code{__builtin_}. GCC provides built-in versions of the ISO C99 floating point comparison macros that avoid raising exceptions for unordered operands. They have the same names as the standard macros ( @code{isgreater}, @code{isgreaterequal}, @code{isless}, @code{islessequal}, @code{islessgreater}, and @code{isunordered}) , with @code{__builtin_} prefixed. We intend for a library implementor to be able to simply @code{#define} each standard macro to its built-in equivalent. @deftypefn {Built-in Function} int __builtin_types_compatible_p (@var{type1}, @var{type2}) You can use the built-in function @code{__builtin_types_compatible_p} to determine whether two types are the same. This built-in function returns 1 if the unqualified versions of the types @var{type1} and @var{type2} (which are types, not expressions) are compatible, 0 otherwise. The result of this built-in function can be used in integer constant expressions. This built-in function ignores top level qualifiers (e.g., @code{const}, @code{volatile}). For example, @code{int} is equivalent to @code{const int}. The type @code{int[]} and @code{int[5]} are compatible. On the other hand, @code{int} and @code{char *} are not compatible, even if the size of their types, on the particular architecture are the same. Also, the amount of pointer indirection is taken into account when determining similarity. Consequently, @code{short *} is not similar to @code{short **}. Furthermore, two types that are typedefed are considered compatible if their underlying types are compatible. An @code{enum} type is not considered to be compatible with another @code{enum} type even if both are compatible with the same integer type; this is what the C standard specifies. For example, @code{enum @{foo, bar@}} is not similar to @code{enum @{hot, dog@}}. You would typically use this function in code whose execution varies depending on the arguments' types. For example: @smallexample #define foo(x) \ (@{ \ typeof (x) tmp = (x); \ if (__builtin_types_compatible_p (typeof (x), long double)) \ tmp = foo_long_double (tmp); \ else if (__builtin_types_compatible_p (typeof (x), double)) \ tmp = foo_double (tmp); \ else if (__builtin_types_compatible_p (typeof (x), float)) \ tmp = foo_float (tmp); \ else \ abort (); \ tmp; \ @}) @end smallexample @emph{Note:} This construct is only available for C@. @end deftypefn @deftypefn {Built-in Function} @var{type} __builtin_choose_expr (@var{const_exp}, @var{exp1}, @var{exp2}) You can use the built-in function @code{__builtin_choose_expr} to evaluate code depending on the value of a constant expression. This built-in function returns @var{exp1} if @var{const_exp}, which is a constant expression that must be able to be determined at compile time, is nonzero. Otherwise it returns 0. This built-in function is analogous to the @samp{? :} operator in C, except that the expression returned has its type unaltered by promotion rules. Also, the built-in function does not evaluate the expression that was not chosen. For example, if @var{const_exp} evaluates to true, @var{exp2} is not evaluated even if it has side-effects. This built-in function can return an lvalue if the chosen argument is an lvalue. If @var{exp1} is returned, the return type is the same as @var{exp1}'s type. Similarly, if @var{exp2} is returned, its return type is the same as @var{exp2}. Example: @smallexample #define foo(x) \ __builtin_choose_expr ( \ __builtin_types_compatible_p (typeof (x), double), \ foo_double (x), \ __builtin_choose_expr ( \ __builtin_types_compatible_p (typeof (x), float), \ foo_float (x), \ /* @r{The void expression results in a compile-time error} \ @r{when assigning the result to something.} */ \ (void)0)) @end smallexample @emph{Note:} This construct is only available for C@. Furthermore, the unused expression (@var{exp1} or @var{exp2} depending on the value of @var{const_exp}) may still generate syntax errors. This may change in future revisions. @end deftypefn @deftypefn {Built-in Function} int __builtin_constant_p (@var{exp}) You can use the built-in function @code{__builtin_constant_p} to determine if a value is known to be constant at compile-time and hence that GCC can perform constant-folding on expressions involving that value. The argument of the function is the value to test. The function returns the integer 1 if the argument is known to be a compile-time constant and 0 if it is not known to be a compile-time constant. A return of 0 does not indicate that the value is @emph{not} a constant, but merely that GCC cannot prove it is a constant with the specified value of the @option{-O} option. You would typically use this function in an embedded application where memory was a critical resource. If you have some complex calculation, you may want it to be folded if it involves constants, but need to call a function if it does not. For example: @smallexample #define Scale_Value(X) \ (__builtin_constant_p (X) \ ? ((X) * SCALE + OFFSET) : Scale (X)) @end smallexample You may use this built-in function in either a macro or an inline function. However, if you use it in an inlined function and pass an argument of the function as the argument to the built-in, GCC will never return 1 when you call the inline function with a string constant or compound literal (@pxref{Compound Literals}) and will not return 1 when you pass a constant numeric value to the inline function unless you specify the @option{-O} option. You may also use @code{__builtin_constant_p} in initializers for static data. For instance, you can write @smallexample static const int table[] = @{ __builtin_constant_p (EXPRESSION) ? (EXPRESSION) : -1, /* @r{@dots{}} */ @}; @end smallexample @noindent This is an acceptable initializer even if @var{EXPRESSION} is not a constant expression. GCC must be more conservative about evaluating the built-in in this case, because it has no opportunity to perform optimization. Previous versions of GCC did not accept this built-in in data initializers. The earliest version where it is completely safe is 3.0.1. @end deftypefn @deftypefn {Built-in Function} long __builtin_expect (long @var{exp}, long @var{c}) @opindex fprofile-arcs You may use @code{__builtin_expect} to provide the compiler with branch prediction information. In general, you should prefer to use actual profile feedback for this (@option{-fprofile-arcs}), as programmers are notoriously bad at predicting how their programs actually perform. However, there are applications in which this data is hard to collect. The return value is the value of @var{exp}, which should be an integral expression. The value of @var{c} must be a compile-time constant. The semantics of the built-in are that it is expected that @var{exp} == @var{c}. For example: @smallexample if (__builtin_expect (x, 0)) foo (); @end smallexample @noindent would indicate that we do not expect to call @code{foo}, since we expect @code{x} to be zero. Since you are limited to integral expressions for @var{exp}, you should use constructions such as @smallexample if (__builtin_expect (ptr != NULL, 1)) error (); @end smallexample @noindent when testing pointer or floating-point values. @end deftypefn @deftypefn {Built-in Function} void __builtin_prefetch (const void *@var{addr}, ...) This function is used to minimize cache-miss latency by moving data into a cache before it is accessed. You can insert calls to @code{__builtin_prefetch} into code for which you know addresses of data in memory that is likely to be accessed soon. If the target supports them, data prefetch instructions will be generated. If the prefetch is done early enough before the access then the data will be in the cache by the time it is accessed. The value of @var{addr} is the address of the memory to prefetch. There are two optional arguments, @var{rw} and @var{locality}. The value of @var{rw} is a compile-time constant one or zero; one means that the prefetch is preparing for a write to the memory address and zero, the default, means that the prefetch is preparing for a read. The value @var{locality} must be a compile-time constant integer between zero and three. A value of zero means that the data has no temporal locality, so it need not be left in the cache after the access. A value of three means that the data has a high degree of temporal locality and should be left in all levels of cache possible. Values of one and two mean, respectively, a low or moderate degree of temporal locality. The default is three. @smallexample for (i = 0; i < n; i++) @{ a[i] = a[i] + b[i]; __builtin_prefetch (&a[i+j], 1, 1); __builtin_prefetch (&b[i+j], 0, 1); /* @r{@dots{}} */ @} @end smallexample Data prefetch does not generate faults if @var{addr} is invalid, but the address expression itself must be valid. For example, a prefetch of @code{p->next} will not fault if @code{p->next} is not a valid address, but evaluation will fault if @code{p} is not a valid address. If the target does not support data prefetch, the address expression is evaluated if it includes side effects but no other code is generated and GCC does not issue a warning. @end deftypefn @deftypefn {Built-in Function} double __builtin_huge_val (void) Returns a positive infinity, if supported by the floating-point format, else @code{DBL_MAX}. This function is suitable for implementing the ISO C macro @code{HUGE_VAL}. @end deftypefn @deftypefn {Built-in Function} float __builtin_huge_valf (void) Similar to @code{__builtin_huge_val}, except the return type is @code{float}. @end deftypefn @deftypefn {Built-in Function} {long double} __builtin_huge_vall (void) Similar to @code{__builtin_huge_val}, except the return type is @code{long double}. @end deftypefn @deftypefn {Built-in Function} double __builtin_inf (void) Similar to @code{__builtin_huge_val}, except a warning is generated if the target floating-point format does not support infinities. @end deftypefn @deftypefn {Built-in Function} _Decimal32 __builtin_infd32 (void) Similar to @code{__builtin_inf}, except the return type is @code{_Decimal32}. @end deftypefn @deftypefn {Built-in Function} _Decimal64 __builtin_infd64 (void) Similar to @code{__builtin_inf}, except the return type is @code{_Decimal64}. @end deftypefn @deftypefn {Built-in Function} _Decimal128 __builtin_infd128 (void) Similar to @code{__builtin_inf}, except the return type is @code{_Decimal128}. @end deftypefn @deftypefn {Built-in Function} float __builtin_inff (void) Similar to @code{__builtin_inf}, except the return type is @code{float}.

Since ISO C99 defines this function in terms of @code{strtod}, which we do not implement, a description of the parsing is in order. The string is parsed as by @code{strtol}; that is, the base is recognized by leading @samp{0} or @samp{0x} prefixes. The number parsed is placed in the significand such that the least significant bit of the number is at the least significant bit of the significand. The number is truncated to fit the significand field provided. The significand is forced to be a quiet NaN@. This function, if given a string literal all of which would have been consumed by strtol, is evaluated early enough that it is considered a compile-time constant. @end deftypefn @deftypefn {Built-in Function} _Decimal32 __builtin_nand32 (const char *str) Similar to @code{__builtin_nan}, except the return type is @code{_Decimal32}. @end deftypefn @deftypefn {Built-in Function} _Decimal64 __builtin_nand64 (const char *str) Similar to @code{__builtin_nan}, except the return type is @code{_Decimal64}. @end deftypefn @deftypefn {Built-in Function} _Decimal128 __builtin_nand128 (const char *str) Similar to @code{__builtin_nan}, except the return type is @code{_Decimal128}. @end deftypefn @deftypefn {Built-in Function} float __builtin_nanf (const char *str) Similar to @code{__builtin_nan}, except the return type is @code{float}. @end deftypefn @deftypefn {Built-in Function} {long double} __builtin_nanl (const char *str) Similar to @code{__builtin_nan}, except the return type is @code{long double}. @end deftypefn @deftypefn {Built-in Function} double __builtin_nans (const char *str) Similar to @code{__builtin_nan}, except the significand is forced to be a signaling NaN@.

Blackfin Built-in Functions @subsection Blackfin Built-in Functions Currently, there are two Blackfin-specific built-in functions. These are used for generating @code{CSYNC} and @code{SSYNC} machine insns without using inline assembly; by using these built-in functions the compiler can automatically add workarounds for hardware errata involving these instructions. These functions are named as follows: @smallexample void __builtin_bfin_csync (void) void __builtin_bfin_ssync (void) @end smallexample @node FR-V Built-in Functions @subsection FR-V Built-in Functions GCC provides many FR-V-specific built-in functions. In general, these functions are intended to be compatible with those described by @cite{FR-V Family, Softune C/C++ Compiler Manual (V6), Fujitsu Semiconductor}. The two exceptions are @code{__MDUNPACKH} and @code{__MBTOHE}, the gcc forms of which pass 128-bit values by pointer rather than by value. Most of the functions are named after specific FR-V instructions. Such functions are said to be ``directly mapped'' and are summarized here in tabular form. @menu * Argument Types:: * Directly-mapped Integer Functions:: * Directly-mapped Media Functions:: * Raw read/write Functions:: * Other Built-in Functions:: @end menu @node Argument Types @subsubsection Argument Types The arguments to the built-in functions can be divided into three groups: register numbers, compile-time constants and run-time values. In order to make this classification clear at a glance, the arguments and return values are given the following pseudo types: @multitable @columnfractions .20 .30 .15 .35 @item Pseudo type @tab Real C type @tab Constant? @tab Description @item @code{uh} @tab @code{unsigned short} @tab No @tab an unsigned halfword @item @code{uw1} @tab @code{unsigned int} @tab No @tab an unsigned word @item @code{sw1} @tab @code{int} @tab No @tab a signed word @item @code{uw2} @tab @code{unsigned long long} @tab No @tab an unsigned doubleword @item @code{sw2} @tab @code{long long} @tab No @tab a signed doubleword @item @code{const} @tab @code{int} @tab Yes @tab an integer constant @item @code{acc} @tab @code{int} @tab Yes @tab an ACC register number @item @code{iacc} @tab @code{int} @tab Yes @tab an IACC register number @end multitable These pseudo types are not defined by GCC, they are simply a notational convenience used in this manual. Arguments of type @code{uh}, @code{uw1}, @code{sw1}, @code{uw2} and @code{sw2} are evaluated at run time. They correspond to register operands in the underlying FR-V instructions. @code{const} arguments represent immediate operands in the underlying FR-V instructions. They must be compile-time constants. @code{acc} arguments are evaluated at compile time and specify the number of an accumulator register. For example, an @code{acc} argument of 2 will select the ACC2 register. @code{iacc} arguments are similar to @code{acc} arguments but specify the number of an IACC register.

Note that, if you specify command-line switches such as @option{-msse}, the compiler could use the extended instruction sets even if the built-ins are not used explicitly in the program. For this reason, applications which perform runtime CPU detection must compile separate files for each supported architecture, using the appropriate flags. In particular, the file containing the CPU detection code should be compiled without these options. The following machine modes are available for use with MMX built-in functions (@pxref{Vector Extensions}): @code{V2SI} for a vector of two 32-bit integers, @code{V4HI} for a vector of four 16-bit integers, and @code{V8QI} for a vector of eight 8-bit integers. Some of the built-in functions operate on MMX registers as a whole 64-bit entity, these use @code{DI} as their mode. If 3Dnow extensions are enabled, @code{V2SF} is used as a mode for a vector of two 32-bit floating point values. If SSE extensions are enabled, @code{V4SF} is used for a vector of four 32-bit floating point values. Some instructions use a vector of four 32-bit integers, these use @code{V4SI}. Finally, some instructions operate on an entire vector register, interpreting it as a 128-bit integer, these use mode @code{TI}. The following built-in functions are made available by @option{-mmmx}. All of them generate the machine instruction that is part of the name. @smallexample v8qi __builtin_ia32_paddb (v8qi, v8qi) v4hi __builtin_ia32_paddw (v4hi, v4hi) v2si __builtin_ia32_paddd (v2si, v2si) v8qi __builtin_ia32_psubb (v8qi, v8qi) v4hi __builtin_ia32_psubw (v4hi, v4hi) v2si __builtin_ia32_psubd (v2si, v2si) v8qi __builtin_ia32_paddsb (v8qi, v8qi) v4hi __builtin_ia32_paddsw (v4hi, v4hi) v8qi __builtin_ia32_psubsb (v8qi, v8qi) v4hi __builtin_ia32_psubsw (v4hi, v4hi) v8qi __builtin_ia32_paddusb (v8qi, v8qi) v4hi __builtin_ia32_paddusw (v4hi, v4hi) v8qi __builtin_ia32_psubusb (v8qi, v8qi) v4hi __builtin_ia32_psubusw (v4hi, v4hi) v4hi __builtin_ia32_pmullw (v4hi, v4hi) v4hi __builtin_ia32_pmulhw (v4hi, v4hi) di __builtin_ia32_pand (di, di) di __builtin_ia32_pandn (di,di) di __builtin_ia32_por (di, di) di __builtin_ia32_pxor (di, di) v8qi __builtin_ia32_pcmpeqb (v8qi, v8qi) v4hi __builtin_ia32_pcmpeqw (v4hi, v4hi) v2si __builtin_ia32_pcmpeqd (v2si, v2si) v8qi __builtin_ia32_pcmpgtb (v8qi, v8qi) v4hi __builtin_ia32_pcmpgtw (v4hi, v4hi) v2si __builtin_ia32_pcmpgtd (v2si, v2si) v8qi __builtin_ia32_punpckhbw (v8qi, v8qi) v4hi __builtin_ia32_punpckhwd (v4hi, v4hi) v2si __builtin_ia32_punpckhdq (v2si, v2si) v8qi __builtin_ia32_punpcklbw (v8qi, v8qi) v4hi __builtin_ia32_punpcklwd (v4hi, v4hi) v2si __builtin_ia32_punpckldq (v2si, v2si) v8qi __builtin_ia32_packsswb (v4hi, v4hi) v4hi __builtin_ia32_packssdw (v2si, v2si) v8qi __builtin_ia32_packuswb (v4hi, v4hi) @end smallexample The following built-in functions are made available either with @option{-msse}, or with a combination of @option{-m3dnow} and @option{-march=athlon}.

It provides instructions that operate on packed 8-bit integer data, Q15 fractional data and Q31 fractional data. GCC supports MIPS DSP operations using both the generic vector extensions (@pxref{Vector Extensions}) and a collection of MIPS-specific built-in functions. Both kinds of support are enabled by the @option{-mdsp} command-line option. At present, GCC only provides support for operations on 32-bit vectors. The vector type associated with 8-bit integer data is usually called @code{v4i8} and the vector type associated with Q15 is usually called @code{v2q15}. They can be defined in C as follows: @smallexample typedef char v4i8 __attribute__ ((vector_size(4))); typedef short v2q15 __attribute__ ((vector_size(4))); @end smallexample @code{v4i8} and @code{v2q15} values are initialized in the same way as aggregates. For example: @smallexample v4i8 a = @{1, 2, 3, 4@}; v4i8 b; b = (v4i8) @{5, 6, 7, 8@}; v2q15 c = @{0x0fcb, 0x3a75@}; v2q15 d; d = (v2q15) @{0.1234 * 0x1.0p15, 0.4567 * 0x1.0p15@}; @end smallexample @emph{Note:} The CPU's endianness determines the order in which values are packed. On little-endian targets, the first value is the least significant and the last value is the most significant. The opposite order applies to big-endian targets. For example, the code above will set the lowest byte of @code{a} to @code{1} on little-endian targets and @code{4} on big-endian targets. @emph{Note:} Q15 and Q31 values must be initialized with their integer representation. As shown in this example, the integer representation of a Q15 value can be obtained by multiplying the fractional value by @code{0x1.0p15}. The equivalent for Q31 values is to multiply by @code{0x1.0p31}. The table below lists the @code{v4i8} and @code{v2q15} operations for which hardware support exists. @code{a} and @code{b} are @code{v4i8} values, and @code{c} and @code{d} are @code{v2q15} values. @multitable @columnfractions .50 .50 @item C code @tab MIPS instruction @item @code{a + b} @tab @code{addu.qb} @item @code{c + d} @tab @code{addq.ph} @item @code{a - b} @tab @code{subu.qb} @item @code{c - d} @tab @code{subq.ph} @end multitable It is easier to describe the DSP built-in functions if we first define the following types: @smallexample typedef int q31; typedef int i32; typedef long long a64; @end smallexample @code{q31} and @code{i32} are actually the same as @code{int}, but we use @code{q31} to indicate a Q31 fractional value and @code{i32} to indicate a 32-bit integer value. Similarly, @code{a64} is the same as @code{long long}, but we use @code{a64} to indicate values that will be placed in one of the four DSP accumulators (@code{$ac0}, @code{$ac1}, @code{$ac2} or @code{$ac3}).

Each pair is packed into a 64-bit floating-point register, with one element being designated the ``upper half'' and the other being designated the ``lower half''. GCC supports paired-single operations using both the generic vector extensions (@pxref{Vector Extensions}) and a collection of MIPS-specific built-in functions. Both kinds of support are enabled by the @option{-mpaired-single} command-line option. The vector type associated with paired-single values is usually called @code{v2sf}. It can be defined in C as follows: @smallexample typedef float v2sf __attribute__ ((vector_size (8))); @end smallexample @code{v2sf} values are initialized in the same way as aggregates. For example: @smallexample v2sf a = @{1.5, 9.1@}; v2sf b; float e, f; b = (v2sf) @{e, f@}; @end smallexample @emph{Note:} The CPU's endianness determines which value is stored in the upper half of a register and which value is stored in the lower half. On little-endian targets, the first value is the lower one and the second value is the upper one. The opposite order applies to big-endian targets. For example, the code above will set the lower half of @code{a} to @code{1.5} on little-endian targets and @code{9.1} on big-endian targets. @menu * Paired-Single Arithmetic:: * Paired-Single Built-in Functions:: * MIPS-3D Built-in Functions:: @end menu @node Paired-Single Arithmetic @subsubsection Paired-Single Arithmetic The table below lists the @code{v2sf} operations for which hardware support exists. @code{a}, @code{b} and @code{c} are @code{v2sf} values and @code{x} is an integral value. @multitable @columnfractions .50 .50 @item C code @tab MIPS instruction @item @code{a + b} @tab @code{add.ps} @item @code{a - b} @tab @code{sub.ps} @item @code{-a} @tab @code{neg.ps} @item @code{a * b} @tab @code{mul.ps} @item @code{a * b + c} @tab @code{madd.ps} @item @code{a * b - c} @tab @code{msub.ps} @item @code{-(a * b + c)} @tab @code{nmadd.ps} @item @code{-(a * b - c)} @tab @code{nmsub.ps} @item @code{x ? a : b} @tab @code{movn.ps}/@code{movz.ps} @end multitable Note that the multiply-accumulate instructions can be disabled using the command-line option @code{-mno-fused-madd}. @node Paired-Single Built-in Functions @subsubsection Paired-Single Built-in Functions The following paired-single functions map directly to a particular MIPS instruction.

The default varies depending on the operating system, so a portable program should always specify the signedness. @item Compiling with @option{-maltivec} adds keywords @code{__vector}, @code{__pixel}, and @code{__bool}. Macros @option{vector}, @code{pixel}, and @code{bool} are defined in @code{} and can be undefined. @item GCC allows using a @code{typedef} name as the type specifier for a vector type. @item For C, overloaded functions are implemented with macros so the following does not work: @smallexample vec_add ((vector signed int)@{1, 2, 3, 4@}, foo); @end smallexample Since @code{vec_add} is a macro, the vector constant in the example is treated as four separate arguments.

Use with care! This pragma must be before any function in the file, and mixing different memregs values in different objects may make them incompatible. This pragma is useful when a performance-critical function uses a memreg for temporary values, as it may allow you to reduce the number of memregs used. @end table @node RS/6000 and PowerPC Pragmas @subsection RS/6000 and PowerPC Pragmas The RS/6000 and PowerPC targets define one pragma for controlling whether or not the @code{longcall} attribute is added to function declarations by default.

These are useful for compatibility with other Mac OS compilers. @table @code @item mark @var{tokens}@dots{} @cindex pragma, mark This pragma is accepted, but has no effect. @item options align=@var{alignment} @cindex pragma, options align This pragma sets the alignment of fields in structures. The values of @var{alignment} may be @code{mac68k}, to emulate m68k alignment, or @code{power}, to emulate PowerPC alignment. Uses of this pragma nest properly; to restore the previous setting, use @code{reset} for the @var{alignment}. @item segment @var{tokens}@dots{} @cindex pragma, segment This pragma is accepted, but has no effect. @item unused (@var{var} [, @var{var}]@dots{}) @cindex pragma, unused This pragma declares variables to be possibly unused. GCC will not produce warnings for the listed variables. The effect is similar to that of the @code{unused} attribute, except that this pragma may appear anywhere within the variables' scopes. @end table @node Solaris Pragmas @subsection Solaris Pragmas The Solaris target supports @code{#pragma redefine_extname} (@pxref{Symbol-Renaming Pragmas}). It also supports additional @code{#pragma} directives for compatibility with the system compiler. @table @code @item align @var{alignment} (@var{variable} [, @var{variable}]...) @cindex pragma, align Increase the minimum alignment of each @var{variable} to @var{alignment}. This is the same as GCC's @code{aligned} attribute @pxref{Variable Attributes}). Macro expansion occurs on the arguments to this pragma -when compiling C and Objective-C. It does not currently occur when -compiling C++, but this is a bug which may be fixed in a future -release. +when compiling C. It does not currently occur when compiling C++, but +this is a bug which may be fixed in a future release. @item fini (@var{function} [, @var{function}]...) @cindex pragma, fini This pragma causes each listed @var{function} to be called after main, or during shared module unloading, by adding a call to the @code{.fini} section. @item init (@var{function} [, @var{function}]...) @cindex pragma, init This pragma causes each listed @var{function} to be called during initialization (before @code{main}) or during shared module loading, by adding a call to the @code{.init} section. @end table @node Symbol-Renaming Pragmas @subsection Symbol-Renaming Pragmas For compatibility with the Solaris and Tru64 UNIX system headers, GCC supports two @code{#pragma} directives which change the name used in assembly for a given declaration. These pragmas are only available on platforms whose system headers need them. To get this effect on all platforms supported by GCC, use the asm labels extension (@pxref{Asm Labels}). @table @code @item redefine_extname @var{oldname} @var{newname} @cindex pragma, redefine_extname This pragma gives the C function @var{oldname} the assembly symbol @var{newname}. The preprocessor macro @code{__PRAGMA_REDEFINE_EXTNAME} will be defined if this pragma is available (currently only on Solaris). @item extern_prefix @var{string} @cindex pragma, extern_prefix This pragma causes all subsequent external function and variable declarations to have @var{string} prepended to their assembly symbols. This effect may be terminated with another @code{extern_prefix} pragma whose argument is an empty string. The preprocessor macro @code{__PRAGMA_EXTERN_PREFIX} will be defined if this pragma is available (currently only on Tru64 UNIX)@. @end table These pragmas and the asm labels extension interact in a complicated manner. Here are some corner cases you may want to be aware of. @enumerate @item Both pragmas silently apply only to declarations with external linkage. Asm labels do not have this restriction. @item In C++, both pragmas silently apply only to declarations with ``C'' linkage. Again, asm labels do not have this restriction. @item If any of the three ways of changing the assembly name of a declaration is applied to a declaration whose assembly name has already been determined (either by a previous use of one of these features, or because the compiler needed the assembly name in order to generate code), and the new name is different, a warning issues and the name does not change. @item The @var{oldname} used by @code{#pragma redefine_extname} is always the C-language name. @item If @code{#pragma extern_prefix} is in effect, and a declaration occurs with an asm label attached, the prefix is silently ignored for that declaration. @item If @code{#pragma extern_prefix} and @code{#pragma redefine_extname} apply to the same declaration, whichever triggered first wins, and a warning issues if they contradict each other. (We would like to have @code{#pragma redefine_extname} always win, for consistency with asm labels, but if @code{#pragma extern_prefix} triggers first we have no way of knowing that that happened.) @end enumerate @node Structure-Packing Pragmas @subsection Structure-Packing Pragmas For compatibility with Win32, GCC supports a set of @code{#pragma} directives which change the maximum alignment of members of structures (other than zero-width bitfields), unions, and classes subsequently defined. The @var{n} value below always is required to be a small power of two and specifies the new alignment in bytes. @enumerate @item @code{#pragma pack(@var{n})} simply sets the new alignment. @item @code{#pragma pack()} sets the alignment to the one that was in effect when compilation started (see also command line option @option{-fpack-struct[=]} @pxref{Code Gen Options}). @item @code{#pragma pack(push[,@var{n}])} pushes the current alignment setting on an internal stack and then optionally sets the new alignment. @item @code{#pragma pack(pop)} restores the alignment setting to the one saved at the top of the internal stack (and removes that stack entry). Note that @code{#pragma pack([@var{n}])} does not influence this internal stack; thus it is possible to have @code{#pragma pack(push)} followed by multiple @code{#pragma pack(@var{n})} instances and finalized by a single @code{#pragma pack(pop)}. @end enumerate Some targets, e.g. i386 and powerpc, support the @code{ms_struct} @code{#pragma} which lays out a structure as the documented @code{__attribute__ ((ms_struct))}. @enumerate @item @code{#pragma ms_struct on} turns on the layout for structures declared. @item @code{#pragma ms_struct off} turns off the layout for structures declared. @item @code{#pragma ms_struct reset} goes back to the default layout. @end enumerate @node Weak Pragmas @subsection Weak Pragmas For compatibility with SVR4, GCC supports a set of @code{#pragma} directives for declaring symbols to be weak, and defining weak aliases. @table @code @item #pragma weak @var{symbol} @cindex pragma, weak This pragma declares @var{symbol} to be weak, as if the declaration had the attribute of the same name. The pragma may appear before or after the declaration of @var{symbol}, but must appear before either its first use or its definition. It is not an error for @var{symbol} to never be defined at all. @item #pragma weak @var{symbol1} = @var{symbol2} This pragma declares @var{symbol1} to be a weak alias of @var{symbol2}. It is an error if @var{symbol2} is not defined in the current translation unit. @end table @node Diagnostic Pragmas @subsection Diagnostic Pragmas GCC allows the user to selectively enable or disable certain types of diagnostics, and change the kind of the diagnostic. For example, a project's policy might require that all sources compile with @option{-Werror} but certain files might have exceptions allowing specific types of warnings. Or, a project might selectively enable diagnostics and treat them as errors depending on which preprocessor macros are defined. @table @code @item #pragma GCC diagnostic @var{kind} @var{option} @cindex pragma, diagnostic Modifies the disposition of a diagnostic. Note that not all diagnostics are modifiable; at the moment only warnings (normally controlled by @samp{-W...}) can be controlled, and not all of them. Use @option{-fdiagnostics-show-option} to determine which diagnostics are controllable and which option controls them. @var{kind} is @samp{error} to treat this diagnostic as an error, @samp{warning} to treat it like a warning (even if @option{-Werror} is in effect), or @samp{ignored} if the diagnostic is to be ignored. @var{option} is a double quoted string which matches the command line option. @example #pragma GCC diagnostic warning "-Wformat" #pragma GCC diagnostic error "-Wformat" #pragma GCC diagnostic ignored "-Wformat" @end example Note that these pragmas override any command line options. Also, while it is syntactically valid to put these pragmas anywhere in your sources, the only supported location for them is before any data or functions are defined. Doing otherwise may result in unpredictable results depending on how the optimizer manages your sources. If the same option is listed multiple times, the last one specified is the one that is in effect. This pragma is not intended to be a general purpose replacement for command line options, but for implementing strict control over project policies. @end table @node Visibility Pragmas @subsection Visibility Pragmas @table @code @item #pragma GCC visibility push(@var{visibility}) @itemx #pragma GCC visibility pop @cindex pragma, visibility This pragma allows the user to set the visibility for multiple declarations without having to give each a visibility attribute @xref{Function Attributes}, for more information about visibility and the attribute syntax. In C++, @samp{#pragma GCC visibility} affects only namespace-scope declarations. Class members and template specializations are not affected; if you want to override the visibility for a particular member or instantiation, you must use an attribute. @end table @node Unnamed Fields @section Unnamed struct/union fields within structs/unions @cindex struct @cindex union For compatibility with other compilers, GCC allows you to define a structure or union that contains, as fields, structures and unions without names. For example: @smallexample struct @{ int a; union @{ int b; float c; @}; int d; @} foo; @end smallexample In this example, the user would be able to access members of the unnamed union with code like @samp{foo.b}. Note that only unnamed structs and unions are allowed, you may not have, for example, an unnamed @code{int}. You must never create such structures that cause ambiguous field definitions. For example, this structure: @smallexample struct @{ int a; struct @{ int a; @}; @} foo; @end smallexample It is ambiguous which @code{a} is being referred to with @samp{foo.a}. Such constructs are not supported and must be avoided. In the future, such constructs may be detected and treated as compilation errors. @opindex fms-extensions Unless @option{-fms-extensions} is used, the unnamed field must be a structure or union definition without a tag (for example, @samp{struct @{ int a; @};}). If @option{-fms-extensions} is used, the field may also be a definition with a tag such as @samp{struct foo @{ int a; @};}, a reference to a previously defined structure or union such as @samp{struct foo;}, or a reference to a @code{typedef} name for a previously defined structure or union type. @node Thread-Local @section Thread-Local Storage @cindex Thread-Local Storage @cindex @acronym{TLS} @cindex __thread Thread-local storage (@acronym{TLS}) is a mechanism by which variables are allocated such that there is one instance of the variable per extant thread. The run-time model GCC uses to implement this originates in the IA-64 processor-specific ABI, but has since been migrated to other processors as well. It requires significant support from the linker (@command{ld}), dynamic linker (@command{ld.so}), and system libraries (@file{libc.so} and @file{libpthread.so}), so it is not available everywhere. At the user level, the extension is visible with a new storage class keyword: @code{__thread}. For example: @smallexample __thread int i; extern __thread struct state s; static __thread char *p; @end smallexample The @code{__thread} specifier may be used alone, with the @code{extern} or @code{static} specifiers, but with no other storage class specifier. When used with @code{extern} or @code{static}, @code{__thread} must appear immediately after the other storage class specifier. The @code{__thread} specifier may be applied to any global, file-scoped static, function-scoped static, or static data member of a class. It may not be applied to block-scoped automatic or non-static data member. When the address-of operator is applied to a thread-local variable, it is evaluated at run-time and returns the address of the current thread's instance of that variable. An address so obtained may be used by any thread. When a thread terminates, any pointers to thread-local variables in that thread become invalid. No static initialization may refer to the address of a thread-local variable. In C++, if an initializer is present for a thread-local variable, it must be a @var{constant-expression}, as defined in 5.19.2 of the ANSI/ISO C++ standard. See @uref{http://people.redhat.com/drepper/tls.pdf, ELF Handling For Thread-Local Storage} for a detailed explanation of the four thread-local storage addressing models, and how the run-time is expected to function. @menu * C99 Thread-Local Edits:: * C++98 Thread-Local Edits:: @end menu @node C99 Thread-Local Edits @subsection ISO/IEC 9899:1999 Edits for Thread-Local Storage The following are a set of changes to ISO/IEC 9899:1999 (aka C99) that document the exact semantics of the language extension. @itemize @bullet @item @cite{5.1.2 Execution environments} Add new text after paragraph 1 @quotation Within either execution environment, a @dfn{thread} is a flow of control within a program.

If you want to write code that checks whether these features are available, you can test for the GNU compiler the same way as for C programs: check for a predefined macro @code{__GNUC__}. You can also use @code{__GNUG__} to test specifically for GNU C++ (@pxref{Common Predefined Macros,, Predefined Macros,cpp,The GNU C Preprocessor}). @menu * Volatiles:: What constitutes an access to a volatile object. * Restricted Pointers:: C99 restricted pointers and references. * Vague Linkage:: Where G++ puts inlines, vtables and such. * C++ Interface:: You can use a single C++ header file for both declarations and definitions. * Template Instantiation:: Methods for ensuring that exactly one copy of each needed template instantiation is emitted. * Bound member functions:: You can extract a function pointer to the method denoted by a @samp{->*} or @samp{.*} expression. * C++ Attributes:: Variable, function, and type attributes for C++ only. * Namespace Association:: Strong using-directives for namespace association. * Java Exceptions:: Tweaking exception handling to work with Java. * Deprecated Features:: Things will disappear from g++. * Backwards Compatibility:: Compatibilities with earlier definitions of C++. @end menu @node Volatiles @section When is a Volatile Object Accessed? @cindex accessing volatiles @cindex volatile read @cindex volatile write @cindex volatile access Both the C and C++ standard have the concept of volatile objects. These are normally accessed by pointers and used for accessing hardware. The standards encourage compilers to refrain from optimizations concerning accesses to volatile objects. The C standard leaves it implementation defined as to what constitutes a volatile access. The C++ standard omits to specify this, except to say that C++ should behave in a similar manner to C with respect to volatiles, where possible. The minimum either standard specifies is that at a sequence point all previous accesses to volatile objects have stabilized and no subsequent accesses have occurred. Thus an implementation is free to reorder and combine volatile accesses which occur between sequence points, but cannot do so for accesses across a sequence point. The use of volatiles does not allow you to violate the restriction on updating objects multiple times within a sequence point. @xref{Qualifiers implementation, , Volatile qualifier and the C compiler}. The behavior differs slightly between C and C++ in the non-obvious cases: @smallexample volatile int *src = @var{somevalue}; *src; @end smallexample With C, such expressions are rvalues, and GCC interprets this either as a read of the volatile object being pointed to or only as request to evaluate the side-effects. The C++ standard specifies that such expressions do not undergo lvalue to rvalue conversion, and that the type of the dereferenced object may be incomplete. The C++ standard does not specify explicitly that it is this lvalue to rvalue conversion which may be responsible for causing an access. However, there is reason to believe that it is, because otherwise certain simple expressions become undefined. However, because it would surprise most programmers, G++ treats dereferencing a pointer to volatile object of complete type when the value is unused as GCC would do for an equivalent type in C. When the object has incomplete type, G++ issues a warning; if you wish to force an error, you must force a conversion to rvalue with, for instance, a static cast. When using a reference to volatile, G++ does not treat equivalent expressions as accesses to volatiles, but instead issues a warning that no volatile is accessed. The rationale for this is that otherwise it becomes difficult to determine where volatile access occur, and not possible to ignore the return value from functions returning volatile references. Again, if you wish to force a read, cast the reference to an rvalue. @node Restricted Pointers @section Restricting Pointer Aliasing @cindex restricted pointers @cindex restricted references @cindex restricted this pointer As with the C front end, G++ understands the C99 feature of restricted pointers, specified with the @code{__restrict__}, or @code{__restrict} type qualifier. Because you cannot compile C++ by specifying the @option{-std=c99} language flag, @code{restrict} is not a keyword in C++. In addition to allowing restricted pointers, you can specify restricted references, which indicate that the reference is not aliased in the local context. @smallexample void fn (int *__restrict__ rptr, int &__restrict__ rref) @{ /* @r{@dots{}} */ @} @end smallexample @noindent In the body of @code{fn}, @var{rptr} points to an unaliased integer and @var{rref} refers to a (different) unaliased integer. You may also specify whether a member function's @var{this} pointer is unaliased by using @code{__restrict__} as a member function qualifier. @smallexample void T::fn () __restrict__ @{ /* @r{@dots{}} */ @} @end smallexample @noindent Within the body of @code{T::fn}, @var{this} will have the effective definition @code{T *__restrict__ const this}. Notice that the interpretation of a @code{__restrict__} member function qualifier is different to that of @code{const} or @code{volatile} qualifier, in that it is applied to the pointer rather than the object. This is consistent with other compilers which implement restricted pointers. As with all outermost parameter qualifiers, @code{__restrict__} is ignored in function definition matching. This means you only need to specify @code{__restrict__} in a function definition, rather than in a function prototype as well. @node Vague Linkage @section Vague Linkage @cindex vague linkage There are several constructs in C++ which require space in the object file but are not clearly tied to a single translation unit. We say that these constructs have ``vague linkage''. Typically such constructs are emitted wherever they are needed, though sometimes we can be more clever. @table @asis @item Inline Functions Inline functions are typically defined in a header file which can be included in many different compilations. Hopefully they can usually be inlined, but sometimes an out-of-line copy is necessary, if the address of the function is taken or if inlining fails. In general, we emit an out-of-line copy in all translation units where one is needed. As an exception, we only emit inline virtual functions with the vtable, since it will always require a copy. Local static variables and string constants used in an inline function are also considered to have vague linkage, since they must be shared between all inlined and out-of-line instances of the function. @item VTables @cindex vtable C++ virtual functions are implemented in most compilers using a lookup table, known as a vtable. The vtable contains pointers to the virtual functions provided by a class, and each object of the class contains a pointer to its vtable (or vtables, in some multiple-inheritance situations). If the class declares any non-inline, non-pure virtual functions, the first one is chosen as the ``key method'' for the class, and the vtable is only emitted in the translation unit where the key method is defined. @emph{Note:} If the chosen key method is later defined as inline, the vtable will still be emitted in every translation unit which defines it. Make sure that any inline virtuals are declared inline in the class body, even if they are not defined there. @item type_info objects @cindex type_info @cindex RTTI C++ requires information about types to be written out in order to implement @samp{dynamic_cast}, @samp{typeid} and exception handling. For polymorphic classes (classes with virtual functions), the type_info object is written out along with the vtable so that @samp{dynamic_cast} can determine the dynamic type of a class object at runtime. For all other types, we write out the type_info object when it is used: when applying @samp{typeid} to an expression, throwing an object, or referring to a type in a catch clause or exception specification. @item Template Instantiations Most everything in this section also applies to template instantiations, but there are other options as well. @xref{Template Instantiation,,Where's the Template?}. @end table When used with GNU ld version 2.8 or later on an ELF system such as GNU/Linux or Solaris 2, or on Microsoft Windows, duplicate copies of these constructs will be discarded at link time. This is known as COMDAT support. On targets that don't support COMDAT, but do support weak symbols, GCC will use them. This way one copy will override all the others, but the unused copies will still take up space in the executable. For targets which do not support either COMDAT or weak symbols, most entities with vague linkage will be emitted as local symbols to avoid duplicate definition errors from the linker. This will not happen for local statics in inlines, however, as having multiple copies will almost certainly break things. @xref{C++ Interface,,Declarations and Definitions in One Header}, for another way to control placement of these constructs. @node C++ Interface @section #pragma interface and implementation @cindex interface and implementation headers, C++ @cindex C++ interface and implementation headers @cindex pragmas, interface and implementation @code{#pragma interface} and @code{#pragma implementation} provide the user with a way of explicitly directing the compiler to emit entities with vague linkage (and debugging information) in a particular translation unit. @emph{Note:} As of GCC 2.7.2, these @code{#pragma}s are not useful in most cases, because of COMDAT support and the ``key method'' heuristic mentioned in @ref{Vague Linkage}. Using them can actually cause your program to grow due to unnecessary out-of-line copies of inline functions. Currently (3.4) the only benefit of these @code{#pragma}s is reduced duplication of debugging information, and that should be addressed soon on DWARF 2 targets with the use of COMDAT groups. @table @code @item #pragma interface @itemx #pragma interface "@var{subdir}/@var{objects}.h" @kindex #pragma interface Use this directive in @emph{header files} that define object classes, to save space in most of the object files that use those classes. Normally, local copies of certain information (backup copies of inline member functions, debugging information, and the internal tables that implement virtual functions) must be kept in each object file that includes class definitions. You can use this pragma to avoid such duplication. When a header file containing @samp{#pragma interface} is included in a compilation, this auxiliary information will not be generated (unless the main input source file itself uses @samp{#pragma implementation}). Instead, the object files will contain references to be resolved at link time. The second form of this directive is useful for the case where you have multiple headers with the same name in different directories. If you use this form, you must specify the same string to @samp{#pragma implementation}. @item #pragma implementation @itemx #pragma implementation "@var{objects}.h" @kindex #pragma implementation Use this pragma in a @emph{main input file}, when you want full output from included header files to be generated (and made globally visible). The included header file, in turn, should use @samp{#pragma interface}. Backup copies of inline member functions, debugging information, and the internal tables used to implement virtual functions are all generated in implementation files. @cindex implied @code{#pragma implementation} @cindex @code{#pragma implementation}, implied @cindex naming convention, implementation headers If you use @samp{#pragma implementation} with no argument, it applies to an include file with the same basename@footnote{A file's @dfn{basename} was the name stripped of all leading path information and of trailing suffixes, such as @samp{.h} or @samp{.C} or @samp{.cc}.} as your source file. For example, in @file{allclass.cc}, giving just @samp{#pragma implementation} by itself is equivalent to @samp{#pragma implementation "allclass.h"}. In versions of GNU C++ prior to 2.6.0 @file{allclass.h} was treated as an implementation file whenever you would include it from @file{allclass.cc} even if you never specified @samp{#pragma implementation}. This was deemed to be more trouble than it was worth, however, and disabled. Use the string argument if you want a single implementation file to include code from multiple header files. (You must also use @samp{#include} to include the header file; @samp{#pragma implementation} only specifies how to use the file---it doesn't actually include it.) There is no way to split up the contents of a single header file into multiple implementation files. @end table @cindex inlining and C++ pragmas @cindex C++ pragmas, effect on inlining @cindex pragmas in C++, effect on inlining @samp{#pragma implementation} and @samp{#pragma interface} also have an effect on function inlining. If you define a class in a header file marked with @samp{#pragma interface}, the effect on an inline function defined in that class is similar to an explicit @code{extern} declaration---the compiler emits no code at all to define an independent version of the function. Its definition is used only for inlining with its callers. @opindex fno-implement-inlines Conversely, when you include the same header file in a main source file that declares it as @samp{#pragma implementation}, the compiler emits code for the function itself; this defines a version of the function that can be found via pointers (or by callers compiled without inlining). If all calls to the function can be inlined, you can avoid emitting the function by compiling with @option{-fno-implement-inlines}. If any calls were not inlined, you will get linker errors. @node Template Instantiation @section Where's the Template? @cindex template instantiation C++ templates are the first language feature to require more intelligence from the environment than one usually finds on a UNIX system. Somehow the compiler and linker have to make sure that each template instance occurs exactly once in the executable if it is needed, and not at all otherwise. There are two basic approaches to this problem, which are referred to as the Borland model and the Cfront model. @table @asis @item Borland model Borland C++ solved the template instantiation problem by adding the code equivalent of common blocks to their linker; the compiler emits template instances in each translation unit that uses them, and the linker collapses them together. The advantage of this model is that the linker only has to consider the object files themselves; there is no external complexity to worry about. This disadvantage is that compilation time is increased because the template code is being compiled repeatedly. Code written for this model tends to include definitions of all templates in the header file, since they must be seen to be instantiated. @item Cfront model The AT&T C++ translator, Cfront, solved the template instantiation problem by creating the notion of a template repository, an automatically maintained place where template instances are stored. A more modern version of the repository works as follows: As individual object files are built, the compiler places any template definitions and instantiations encountered in the repository. At link time, the link wrapper adds in the objects in the repository and compiles any needed instances that were not previously emitted. The advantages of this model are more optimal compilation speed and the ability to use the system linker; to implement the Borland model a compiler vendor also needs to replace the linker. The disadvantages are vastly increased complexity, and thus potential for error; for some code this can be just as transparent, but in practice it can been very difficult to build multiple programs in one directory and one program in multiple directories. Code written for this model tends to separate definitions of non-inline member templates into a separate file, which should be compiled separately. @end table When used with GNU ld version 2.8 or later on an ELF system such as GNU/Linux or Solaris 2, or on Microsoft Windows, G++ supports the Borland model. On other systems, G++ implements neither automatic model. A future version of G++ will support a hybrid model whereby the compiler will emit any instantiations for which the template definition is included in the compile, and store template definitions and instantiation context information into the object file for the rest. The link wrapper will extract that information as necessary and invoke the compiler to produce the remaining instantiations. The linker will then combine duplicate instantiations. In the mean time, you have the following options for dealing with template instantiations: @enumerate @item @opindex frepo Compile your template-using code with @option{-frepo}. The compiler will generate files with the extension @samp{.rpo} listing all of the template instantiations used in the corresponding object files which could be instantiated there; the link wrapper, @samp{collect2}, will then update the @samp{.rpo} files to tell the compiler where to place those instantiations and rebuild any affected object files. The link-time overhead is negligible after the first pass, as the compiler will continue to place the instantiations in the same files. This is your best option for application code written for the Borland model, as it will just work. Code written for the Cfront model will need to be modified so that the template definitions are available at one or more points of instantiation; usually this is as simple as adding @code{#include } to the end of each template header. For library code, if you want the library to provide all of the template instantiations it needs, just try to link all of its object files together; the link will fail, but cause the instantiations to be generated as a side effect. Be warned, however, that this may cause conflicts if multiple libraries try to provide the same instantiations. For greater control, use explicit instantiation as described in the next option. @item @opindex fno-implicit-templates Compile your code with @option{-fno-implicit-templates} to disable the implicit generation of template instances, and explicitly instantiate all the ones you use. This approach requires more knowledge of exactly which instances you need than do the others, but it's less mysterious and allows greater control. You can scatter the explicit instantiations throughout your program, perhaps putting them in the translation units where the instances are used or the translation units that define the templates themselves; you can put all of the explicit instantiations you need into one big file; or you can create small files like @smallexample #include "Foo.h" #include "Foo.cc" template class Foo; template ostream& operator << (ostream&, const Foo&); @end smallexample for each of the instances you need, and create a template instantiation library from those. If you are using Cfront-model code, you can probably get away with not using @option{-fno-implicit-templates} when compiling files that don't @samp{#include} the member template definitions. If you use one big file to do the instantiations, you may want to compile it without @option{-fno-implicit-templates} so you get all of the instances required by your explicit instantiations (but not by any other files) without having to specify them as well. G++ has extended the template instantiation syntax given in the ISO standard to allow forward declaration of explicit instantiations (with @code{extern}), instantiation of the compiler support data for a template class (i.e.@: the vtable) without instantiating any of its members (with @code{inline}), and instantiation of only the static data members of a template class, without the support data or member functions (with (@code{static}): @smallexample extern template int max (int, int); inline template class Foo; static template class Foo; @end smallexample @item Do nothing. Pretend G++ does implement automatic instantiation management. Code written for the Borland model will work fine, but each translation unit will contain instances of each of the templates it uses. In a large program, this can lead to an unacceptable amount of code duplication. @end enumerate @node Bound member functions @section Extracting the function pointer from a bound pointer to member function @cindex pmf @cindex pointer to member function @cindex bound pointer to member function In C++, pointer to member functions (PMFs) are implemented using a wide pointer of sorts to handle all the possible call mechanisms; the PMF needs to store information about how to adjust the @samp{this} pointer, and if the function pointed to is virtual, where to find the vtable, and where in the vtable to look for the member function. If you are using PMFs in an inner loop, you should really reconsider that decision. If that is not an option, you can extract the pointer to the function that would be called for a given object/PMF pair and call it directly inside the inner loop, to save a bit of time. Note that you will still be paying the penalty for the call through a function pointer; on most modern architectures, such a call defeats the branch prediction features of the CPU@. This is also true of normal virtual function calls. The syntax for this extension is @smallexample extern A a; extern int (A::*fp)(); typedef int (*fptr)(A *); fptr p = (fptr)(a.*fp); @end smallexample For PMF constants (i.e.@: expressions of the form @samp{&Klasse::Member}), no object is needed to obtain the address of the function. They can be converted to function pointers directly: @smallexample fptr p1 = (fptr)(&A::foo); @end smallexample @opindex Wno-pmf-conversions You must specify @option{-Wno-pmf-conversions} to use this extension. @node C++ Attributes @section C++-Specific Variable, Function, and Type Attributes Some attributes only make sense for C++ programs. @table @code @item init_priority (@var{priority}) @cindex init_priority attribute In Standard C++, objects defined at namespace scope are guaranteed to be initialized in an order in strict accordance with that of their definitions @emph{in a given translation unit}. No guarantee is made for initializations across translation units. However, GNU C++ allows users to control the order of initialization of objects defined at namespace scope with the @code{init_priority} attribute by specifying a relative @var{priority}, a constant integral expression currently bounded between 101 and 65535 inclusive. Lower numbers indicate a higher priority. In the following example, @code{A} would normally be created before @code{B}, but the @code{init_priority} attribute has reversed that order: @smallexample Some_Class A __attribute__ ((init_priority (2000))); Some_Class B __attribute__ ((init_priority (543))); @end smallexample @noindent Note that the particular values of @var{priority} do not matter; only their relative ordering. @item java_interface @cindex java_interface attribute This type attribute informs C++ that the class is a Java interface. It may only be applied to classes declared within an @code{extern "Java"} block. Calls to methods declared in this interface will be dispatched using GCJ's interface table mechanism, instead of regular virtual table dispatch. @end table See also @xref{Namespace Association}. @node Namespace Association @section Namespace Association @strong{Caution:} The semantics of this extension are not fully defined. Users should refrain from using this extension as its semantics may change subtly over time. It is possible that this extension will be removed in future versions of G++. A using-directive with @code{__attribute ((strong))} is stronger than a normal using-directive in two ways: @itemize @bullet @item Templates from the used namespace can be specialized and explicitly instantiated as though they were members of the using namespace. @item The using namespace is considered an associated namespace of all templates in the used namespace for purposes of argument-dependent name lookup. @end itemize The used namespace must be nested within the using namespace so that normal unqualified lookup works properly. This is useful for composing a namespace transparently from implementation namespaces. For example: @smallexample namespace std @{ namespace debug @{ template struct A @{ @}; @} using namespace debug __attribute ((__strong__)); template <> struct A @{ @}; // @r{ok to specialize} template void f (A); @} int main() @{ f (std::A()); // @r{lookup finds} std::f f (std::A()); @} @end smallexample @node Java Exceptions @section Java Exceptions The Java language uses a slightly different exception handling model from C++. Normally, GNU C++ will automatically detect when you are writing C++ code that uses Java exceptions, and handle them appropriately. However, if C++ code only needs to execute destructors when Java exceptions are thrown through it, GCC will guess incorrectly. Sample problematic code is: @smallexample struct S @{ ~S(); @}; extern void bar(); // @r{is written in Java, and may throw exceptions} void foo() @{ S s; bar(); @} @end smallexample @noindent The usual effect of an incorrect guess is a link failure, complaining of a missing routine called @samp{__gxx_personality_v0}. You can inform the compiler that Java exceptions are to be used in a translation unit, irrespective of what it might think, by writing @samp{@w{#pragma GCC java_exceptions}} at the head of the file. This @samp{#pragma} must appear before any functions that throw or catch exceptions, or run destructors when exceptions are thrown through them. You cannot mix Java and C++ exceptions in the same translation unit. It is believed to be safe to throw a C++ exception from one file through another file compiled for the Java exception model, or vice versa, but there may be bugs in this area. @node Deprecated Features @section Deprecated Features In the past, the GNU C++ compiler was extended to experiment with new features, at a time when the C++ language was still evolving. Now that the C++ standard is complete, some of those features are superseded by superior alternatives. Using the old features might cause a warning in some cases that the feature will be dropped in the future. In other cases, the feature might be gone already. While the list below is not exhaustive, it documents some of the options that are now deprecated: @table @code @item -fexternal-templates @itemx -falt-external-templates These are two of the many ways for G++ to implement template instantiation. @xref{Template Instantiation}. The C++ standard clearly defines how template definitions have to be organized across implementation units. G++ has an implicit instantiation mechanism that should work just fine for standard-conforming code. @item -fstrict-prototype @itemx -fno-strict-prototype Previously it was possible to use an empty prototype parameter list to indicate an unspecified number of parameters (like C), rather than no parameters, as C++ demands. This feature has been removed, except where it is required for backwards compatibility @xref{Backwards Compatibility}. @end table G++ allows a virtual function returning @samp{void *} to be overridden by one returning a different pointer type. This extension to the covariant return type rules is now deprecated and will be removed from a future version. The G++ minimum and maximum operators (@samp{?}) and their compound forms (@samp{?=}) have been deprecated and will be removed in a future version. Code using these operators should be modified to use @code{std::min} and @code{std::max} instead. The named return value extension has been deprecated, and is now removed from G++. The use of initializer lists with new expressions has been deprecated, and is now removed from G++. Floating and complex non-type template parameters have been deprecated, and are now removed from G++. The implicit typename extension has been deprecated and is now removed from G++. The use of default arguments in function pointers, function typedefs and other places where they are not permitted by the standard is deprecated and will be removed from a future version of G++. G++ allows floating-point literals to appear in integral constant expressions, e.g. @samp{ enum E @{ e = int(2.2 * 3.7) @} } This extension is deprecated and will be removed from a future version. G++ allows static data members of const floating-point type to be declared with an initializer in a class definition. The standard only allows initializers for static members of const integral types and const enumeration types so this extension has been deprecated and will be removed from a future version. @node Backwards Compatibility @section Backwards Compatibility @cindex Backwards Compatibility @cindex ARM [Annotated C++ Reference Manual] Now that there is a definitive ISO standard C++, G++ has a specification to adhere to. The C++ language evolved over time, and features that used to be acceptable in previous drafts of the standard, such as the ARM [Annotated C++ Reference Manual], are no longer accepted. In order to allow compilation of C++ written to such drafts, G++ contains some backwards compatibilities. @emph{All such backwards compatibility features are liable to disappear in future versions of G++.} They should be considered deprecated @xref{Deprecated Features}. @table @code @item For scope If a variable is declared at for scope, it used to remain in scope until the end of the scope which contained the for statement (rather than just within the for scope). G++ retains this, but issues a warning, if such a variable is accessed outside the for scope. @item Implicit C language Old C system header files did not contain an @code{extern "C" @{@dots{}@}} scope to set the language. On such systems, all header files are implicitly scoped inside a C language scope. Also, an empty prototype @code{()} will be treated as an unspecified number of arguments, rather than no arguments, as C++ demands. @end table Index: head/contrib/gcc/doc/frontends.texi =================================================================== --- head/contrib/gcc/doc/frontends.texi (revision 220754) +++ head/contrib/gcc/doc/frontends.texi (revision 220755) @@ -1,63 +1,59 @@ @c Copyright (C) 1988, 1989, 1992, 1993, 1994, 1995, 1996, 1997, 1998, @c 1999, 2000, 2001, 2004 Free Software Foundation, Inc. @c This is part of the GCC manual. @c For copying conditions, see the file gcc.texi. @node G++ and GCC @chapter Programming Languages Supported by GCC @cindex GCC @cindex GNU Compiler Collection @cindex GNU C Compiler @cindex Ada @cindex Fortran @cindex Java -@cindex Objective-C -@cindex Objective-C++ @cindex treelang GCC stands for ``GNU Compiler Collection''.

The abbreviation @dfn{GCC} has multiple meanings in common use. The current official meaning is ``GNU Compiler Collection'', which refers generically to the complete suite of tools.

Finally, the name is also used when speaking of the @dfn{language-independent} component of GCC: code shared among the compilers for all supported languages.

The \*(L"overall options\*(R" allow you to stop this process at an intermediate stage. For example, the \fB\-c\fR option says not to run the linker. Then the output consists of object files output by the assembler. .PP Other options are passed on to one stage of processing. Some options control the preprocessor and others the compiler itself. Yet other options control the assembler and linker; most of these are not documented here, since you rarely need to use any of them. .PP Most of the command line options that you can use with \s-1GCC\s0 are useful for C programs; when an option is only useful with another language (usually \*(C+), the explanation says so explicitly. If the description for a particular option does not mention a source language, you can use that option with all supported languages. .PP The \fBgcc\fR program accepts options and file names as operands. Many options have multi-letter names; therefore multiple single-letter options may \fInot\fR be grouped: \fB\-dr\fR is very different from \fB\-d\ \-r\fR. .PP You can mix options and other arguments. For the most part, the order you use doesn't matter. Order does matter when you use several options of the same kind; for example, if you specify \fB\-L\fR more than once, the directories are searched in the order specified. .PP Many options have long names starting with \fB\-f\fR or with \&\fB\-W\fR\-\-\-for example, \&\fB\-fmove\-loop\-invariants\fR, \fB\-Wformat\fR and so on. Most of these have both positive and negative forms; the negative form of \&\fB\-ffoo\fR would be \fB\-fno\-foo\fR. This manual documents only one of these two forms, whichever one is not the default. .SH "OPTIONS" .IX Header "OPTIONS" .Sh "Option Summary" .IX Subsection "Option Summary" Here is a summary of all the options, grouped by type.

stages: preprocessing, compilation proper, assembly and linking, always in that order. \s-1GCC\s0 is capable of preprocessing and compiling several files either into several assembler input files, or into one assembler input file; then each assembler input file produces an object file, and linking combines all the object files (those newly compiled, and those specified as input) into an executable file. .PP For any given input file, the file name suffix determines what kind of compilation is done: .IP "\fIfile\fR\fB.c\fR" 4 .IX Item "file.c" C source code which must be preprocessed. .IP

The linking stage simply is not done. The ultimate output is in the form of an object file for each source file. .Sp By default, the object file name for a source file is made by replacing the suffix \fB.c\fR, \fB.i\fR, \fB.s\fR, etc., with \fB.o\fR. .Sp Unrecognized input files, not requiring compilation or assembly, are ignored. .IP "\fB\-S\fR" 4 .IX Item "-S" Stop after the stage of compilation proper; do not assemble.

This applies regardless to whatever sort of output is being produced, whether it be an executable file, an object file, an assembler file or preprocessed C code. .Sp If \fB\-o\fR is not specified, the default is to put an executable file in \fIa.out\fR, the object file for \&\fI\fIsource\fI.\fIsuffix\fI\fR in \fI\fIsource\fI.o\fR, its assembler file in \fI\fIsource\fI.s\fR, a precompiled header file in \&\fI\fIsource\fI.\fIsuffix\fI.gch\fR, and all preprocessed C source on standard output. .IP "\fB\-v\fR" 4 .IX Item "-v" Print (on standard error output) the commands executed to run the stages of compilation. Also print the version number of the compiler driver program and of the preprocessor and the compiler proper. .IP "\fB\-###\fR" 4 .IX Item "-###" Like \fB\-v\fR except the commands are not executed and all command arguments are quoted. This is useful for shell scripts to capture the driver-generated command lines. .IP "\fB\-pipe\fR" 4 .IX Item "-pipe" Use pipes rather than temporary files for communication between the various stages of compilation. This fails to work on some systems where the assembler is unable to read from a pipe; but the \s-1GNU\s0 assembler has no trouble. .IP "\fB\-combine\fR" 4 .IX Item "-combine" If you are compiling multiple source files, this option tells the driver to pass all the source files to the compiler at once (for those languages for which the compiler can handle this). This will allow intermodule analysis (\s-1IMA\s0) to be performed by the compiler. Currently the only language for which this is supported is C. If you pass source files for multiple languages to the driver, using this option, the driver will invoke the compiler(s) that support \s-1IMA\s0 once each, passing each compiler all the source files appropriate for it. For those languages that do not support \&\s-1IMA\s0 this option will be ignored, and the compiler will be invoked once for each source file in that language. If you use this option in conjunction with \fB\-save\-temps\fR, the compiler will generate multiple pre-processed files (one for each source file), but only one (combined) \fI.o\fR or \&\fI.s\fR file. .IP "\fB\-\-help\fR" 4 .IX Item "--help" Print (on the standard output) a description of the command line options understood by \fBgcc\fR. If the \fB\-v\fR option is also specified then \fB\-\-help\fR will also be passed on to the various processes invoked by \fBgcc\fR, so that they can display the command line options they accept. If the \fB\-Wextra\fR option is also specified then command line options which have no documentation associated with them will also be displayed. .IP "\fB\-\-target\-help\fR" 4 .IX Item "--target-help" Print (on the standard output) a description of target specific command line options for each tool. .IP "\fB\-\-version\fR" 4 .IX Item "--version" Display the version number and copyrights of the invoked \s-1GCC\s0. .IP "\fB@\fR\fIfile\fR" 4 .IX Item "@file" Read command-line options from \fIfile\fR. The options read are inserted in place of the original @\fIfile\fR option. If \fIfile\fR does not exist, or cannot be read, then the option will be treated literally, and not removed. .Sp Options in \fIfile\fR are separated by whitespace. A whitespace character may be included in an option by surrounding the entire option in either single or double quotes. Any character (including a backslash) may be included by prefixing the character to be included with a backslash. The \fIfile\fR may itself contain additional @\fIfile\fR options; any such options will be processed recursively. .Sh "Compiling \*(C+ Programs" .IX Subsection "Compiling Programs" \&\*(C+ source files conventionally use one of the suffixes \fB.C\fR, \&\fB.cc\fR, \fB.cpp\fR, \fB.CPP\fR, \fB.c++\fR, \fB.cp\fR, or \&\fB.cxx\fR; \*(C+ header files often use \fB.hh\fR or \fB.H\fR; and preprocessed \*(C+ files use the suffix \fB.ii\fR. \s-1GCC\s0 recognizes files with these names and compiles them as \*(C+ programs even if you call the compiler the same way as for compiling C programs (usually with the name \fBgcc\fR). .PP However, the use of \fBgcc\fR does not add the \*(C+ library. \&\fBg++\fR is a program that calls \s-1GCC\s0 and treats \fB.c\fR, \&\fB.h\fR and \fB.i\fR files as \*(C+ source files instead of C source files unless \fB\-x\fR is used, and automatically specifies linking against the \*(C+ library. This program is also useful when precompiling a C header file with a \fB.h\fR extension for use in \*(C+ compilations. On many systems, \fBg++\fR is also installed with the name \fBc++\fR. .PP When you compile \*(C+ programs, you may specify many of the same command-line options that you use for compiling programs in any language; or command-line options meaningful for C and related languages; or options that are meaningful only for \*(C+ programs. .Sh "Options Controlling C Dialect" .IX Subsection "Options Controlling C Dialect" The following options control the dialect of C (or languages derived -from C, such as \*(C+, Objective-C and Objective\-\*(C+) that the compiler -accepts: +from C, such as \*(C+) that the compiler accepts: .IP "\fB\-ansi\fR" 4 .IX Item "-ansi" In C mode, support all \s-1ISO\s0 C90 programs.

It also enables the undesirable and rarely used \s-1ISO\s0 trigraph feature. For the C compiler, it disables recognition of \*(C+ style \fB//\fR comments as well as the \f(CW\*(C`inline\*(C'\fR keyword. .Sp The alternate keywords \f(CW\*(C`_\|_asm_\|_\*(C'\fR, \f(CW\*(C`_\|_extension_\|_\*(C'\fR, \&\f(CW\*(C`_\|_inline_\|_\*(C'\fR and \f(CW\*(C`_\|_typeof_\|_\*(C'\fR continue to work despite \&\fB\-ansi\fR. You would not want to use them in an \s-1ISO\s0 C program, of course, but it is useful to put them in header files that might be included in compilations done with \fB\-ansi\fR. Alternate predefined macros such as \f(CW\*(C`_\|_unix_\|_\*(C'\fR and \f(CW\*(C`_\|_vax_\|_\*(C'\fR are also available, with or without \fB\-ansi\fR. .Sp The \fB\-ansi\fR option does not cause non-ISO programs to be rejected gratuitously. For that, \fB\-pedantic\fR is required in addition to \fB\-ansi\fR. .Sp The macro \f(CW\*(C`_\|_STRICT_ANSI_\|_\*(C'\fR is predefined when the \fB\-ansi\fR option is used. Some header files may notice this macro and refrain from declaring certain functions or defining certain macros that the \&\s-1ISO\s0 standard doesn't call for; this is to avoid interfering with any programs that might use these names for other things. .Sp Functions which would normally be built in but do not have semantics defined by \s-1ISO\s0 C (such as \f(CW\*(C`alloca\*(C'\fR and \f(CW\*(C`ffs\*(C'\fR) are not built-in functions with \fB\-ansi\fR is used. .IP "\fB\-std=\fR" 4 .IX Item "-std=" Determine the language standard.

Using this option is roughly equivalent to adding the \f(CW\*(C`gnu_inline\*(C'\fR function attribute to all inline functions. .Sp This option is accepted by \s-1GCC\s0 versions 4.1.3 and up. In \s-1GCC\s0 versions prior to 4.3, C99 inline semantics are not supported, and thus this option is effectively assumed to be present regardless of whether or not it is specified; the only effect of specifying it explicitly is to disable warnings about using inline functions in C99 mode. Likewise, the option \fB\-fno\-gnu89\-inline\fR is not supported in versions of \&\s-1GCC\s0 before 4.3.

In C99 mode (\fB\-std=c99\fR or \fB\-std=gnu99\fR), this switch only affects the \f(CW\*(C`asm\*(C'\fR and \f(CW\*(C`typeof\*(C'\fR keywords, since \&\f(CW\*(C`inline\*(C'\fR is a standard keyword in \s-1ISO\s0 C99. .IP "\fB\-fno\-builtin\fR" 4 .IX Item "-fno-builtin" .PD 0 .IP "\fB\-fno\-builtin\-\fR\fIfunction\fR" 4 .IX Item "-fno-builtin-function" .PD Don't recognize built-in functions that do not begin with \&\fB_\|_builtin_\fR as prefix. .Sp \&\s-1GCC\s0 normally generates special code to handle certain built-in functions more efficiently; for instance, calls to \f(CW\*(C`alloca\*(C'\fR may become single instructions that adjust the stack directly, and calls to \f(CW\*(C`memcpy\*(C'\fR may become inline copy loops. The resulting code is often both smaller and faster, but since the function calls no longer appear as such, you cannot set a breakpoint on those calls, nor can you change the behavior of the functions by linking with a different library. In addition, when a function is recognized as a built-in function, \s-1GCC\s0 may use information about that function to warn about problems with calls to that function, or to generate more efficient code, even if the resulting code still contains calls to that function. For example, warnings are given with \fB\-Wformat\fR for bad calls to \&\f(CW\*(C`printf\*(C'\fR, when \f(CW\*(C`printf\*(C'\fR is built in, and \f(CW\*(C`strlen\*(C'\fR is known not to modify global memory. .Sp With the \fB\-fno\-builtin\-\fR\fIfunction\fR option only the built-in function \fIfunction\fR is disabled. \fIfunction\fR must not begin with \fB_\|_builtin_\fR.

Friend functions were documented to work this way in the old Annotated \&\*(C+ Reference Manual, and versions of G++ before 4.1 always worked that way. However, in \s-1ISO\s0 \*(C+ a friend function which is not declared in an enclosing scope can only be found using argument dependent lookup.

This option violates the \*(C+ standard, but may be useful for reducing code size in production builds, much like defining \&\fB\s-1NDEBUG\s0\fR.

These include \f(CW\*(C`ffs\*(C'\fR, \f(CW\*(C`alloca\*(C'\fR, \f(CW\*(C`_exit\*(C'\fR, \&\f(CW\*(C`index\*(C'\fR, \f(CW\*(C`bzero\*(C'\fR, \f(CW\*(C`conjf\*(C'\fR, and other related functions. .IP "\fB\-fno\-operator\-names\fR" 4 .IX Item "-fno-operator-names" Do not treat the operator name keywords \f(CW\*(C`and\*(C'\fR, \f(CW\*(C`bitand\*(C'\fR, \&\f(CW\*(C`bitor\*(C'\fR, \f(CW\*(C`compl\*(C'\fR, \f(CW\*(C`not\*(C'\fR, \f(CW\*(C`or\*(C'\fR and \f(CW\*(C`xor\*(C'\fR as synonyms as keywords. .IP "\fB\-fno\-optional\-diags\fR" 4 .IX Item "-fno-optional-diags" Disable diagnostics that the standard says a compiler does not need to issue. Currently, the only such diagnostic issued by G++ is the one for a name having multiple meanings within a class. .IP "\fB\-fpermissive\fR" 4 .IX Item "-fpermissive" Downgrade some diagnostics about nonconformant code from errors to warnings. Thus, using \fB\-fpermissive\fR will allow some nonconforming code to compile. .IP "\fB\-frepo\fR" 4 .IX Item "-frepo" Enable automatic template instantiation at link time. This option also implies \fB\-fno\-implicit\-templates\fR. .IP "\fB\-fno\-rtti\fR" 4 .IX Item "-fno-rtti" Disable generation of information about every class with virtual functions for use by the \*(C+ runtime type identification features (\fBdynamic_cast\fR and \fBtypeid\fR). If you don't use those parts of the language, you can save some space by using this flag. Note that exception handling uses the same information, but it will generate it as needed. The \fBdynamic_cast\fR operator can still be used for casts that do not require runtime type information, i.e. casts to \f(CW\*(C`void *\*(C'\fR or to unambiguous base classes. .IP "\fB\-fstats\fR" 4 .IX Item "-fstats" Emit statistics about front-end processing at the end of the compilation. This information is generally only useful to the G++ development team. .IP "\fB\-ftemplate\-depth\-\fR\fIn\fR" 4 .IX Item "-ftemplate-depth-n" Set the maximum instantiation depth for template classes to \fIn\fR. A limit on the template instantiation depth is needed to detect endless recursions during template class instantiation. \s-1ANSI/ISO\s0 \*(C+ conforming programs must not rely on a maximum depth greater than 17. .IP "\fB\-fno\-threadsafe\-statics\fR" 4 .IX Item "-fno-threadsafe-statics" Do not emit the extra code to use the routines specified in the \*(C+ \&\s-1ABI\s0 for thread-safe initialization of local statics. You can use this option to reduce code size slightly in code that doesn't need to be thread\-safe. .IP "\fB\-fuse\-cxa\-atexit\fR" 4 .IX Item "-fuse-cxa-atexit" Register destructors for objects with static storage duration with the \&\f(CW\*(C`_\|_cxa_atexit\*(C'\fR function rather than the \f(CW\*(C`atexit\*(C'\fR function. This option is required for fully standards-compliant handling of static destructors, but will only work if your C library supports \&\f(CW\*(C`_\|_cxa_atexit\*(C'\fR. .IP "\fB\-fno\-use\-cxa\-get\-exception\-ptr\fR" 4 .IX Item "-fno-use-cxa-get-exception-ptr" Don't use the \f(CW\*(C`_\|_cxa_get_exception_ptr\*(C'\fR runtime routine. This will cause \f(CW\*(C`std::uncaught_exception\*(C'\fR to be incorrect, but is necessary if the runtime routine is not available. .IP "\fB\-fvisibility\-inlines\-hidden\fR" 4 .IX Item "-fvisibility-inlines-hidden" This switch declares that the user does not attempt to compare pointers to inline methods where the addresses of the two functions were taken in different shared objects. .Sp The effect of this is that \s-1GCC\s0 may, effectively, mark inline methods with \&\f(CW\*(C`_\|_attribute_\|_ ((visibility ("hidden")))\*(C'\fR so that they do not appear in the export table of a \s-1DSO\s0 and do not require a \s-1PLT\s0 indirection when used within the \s-1DSO\s0. Enabling this option can have a dramatic effect on load and link times of a \s-1DSO\s0 as it massively reduces the size of the dynamic export table when the library makes heavy use of templates. .Sp The behaviour of this switch is not quite the same as marking the methods as hidden directly, because it does not affect static variables local to the function or cause the compiler to deduce that the function is defined in only one shared object. .Sp You may mark a method as having a visibility explicitly to negate the effect of the switch for that method. For example, if you do want to compare pointers to a particular inline method, you might mark it as having default visibility. Marking the enclosing class with explicit visibility will have no effect. .Sp Explicitly instantiated inline methods are unaffected by this option as their linkage might otherwise cross a shared library boundary. .IP "\fB\-fno\-weak\fR" 4 .IX Item "-fno-weak" Do not use weak symbol support, even if it is provided by the linker. By default, G++ will use weak symbols if they are available. This option exists only for testing, and should not be used by end\-users; it will result in inferior code and has no benefits. This option may be removed in a future release of G++. .IP "\fB\-nostdinc++\fR" 4 .IX Item "-nostdinc++" Do not search for header files in the standard directories specific to \&\*(C+, but do still search the other standard directories. (This option is used when building the \*(C+ library.) .PP In addition, these optimization, warning, and code generation options have meanings only for \*(C+ programs: .IP "\fB\-fno\-default\-inline\fR" 4 .IX Item "-fno-default-inline" Do not assume \fBinline\fR for functions defined inside a class scope. Note that these functions will have linkage like inline functions; they just won't be inlined by default. .IP "\fB\-Wabi\fR (\*(C+ only)" 4 .IX Item "-Wabi ( only)" Warn when G++ generates code that is probably not compatible with the vendor-neutral \*(C+ \s-1ABI\s0. Although an effort has been made to warn about all such cases, there are probably some cases that are not warned about, even though G++ is generating incompatible code. There may also be cases where warnings are emitted even though the code that is generated will be compatible. .Sp You should rewrite your code to avoid these warnings if you are concerned about the fact that code generated by G++ may not be binary compatible with code generated by other compilers. .Sp The known incompatibilities at this point include: .RS 4 .IP "*" 4 Incorrect handling of tail-padding for bit\-fields. G++ may attempt to pack data into the same byte as a base class. For example: .Sp .Vb 2 \& struct A { virtual void f(); int f1 : 1; }; \& struct B : public A { int f2 : 1; }; .Ve .Sp In this case, G++ will place \f(CW\*(C`B::f2\*(C'\fR into the same byte as\f(CW\*(C`A::f1\*(C'\fR; other compilers will not. You can avoid this problem by explicitly padding \f(CW\*(C`A\*(C'\fR so that its size is a multiple of the byte size on your platform; that will cause G++ and other compilers to layout \f(CW\*(C`B\*(C'\fR identically. .IP "*" 4 Incorrect handling of tail-padding for virtual bases. G++ does not use tail padding when laying out virtual bases. For example: .Sp .Vb 3 \& struct A { virtual void f(); char c1; }; \& struct B { B(); char c2; }; \& struct C : public A, public virtual B {}; .Ve .Sp In this case, G++ will not place \f(CW\*(C`B\*(C'\fR into the tail-padding for \&\f(CW\*(C`A\*(C'\fR; other compilers will. You can avoid this problem by explicitly padding \f(CW\*(C`A\*(C'\fR so that its size is a multiple of its alignment (ignoring virtual base classes); that will cause G++ and other compilers to layout \f(CW\*(C`C\*(C'\fR identically. .IP "*" 4 Incorrect handling of bit-fields with declared widths greater than that of their underlying types, when the bit-fields appear in a union. For example: .Sp .Vb 1 \& union U { int i : 4096; }; .Ve .Sp Assuming that an \f(CW\*(C`int\*(C'\fR does not have 4096 bits, G++ will make the union too small by the number of bits in an \f(CW\*(C`int\*(C'\fR. .IP "*" 4 Empty classes can be placed at incorrect offsets. For example: .Sp .Vb 1 \& struct A {}; .Ve .Sp .Vb 4 \& struct B { \& A a; \& virtual void f (); \& }; .Ve .Sp .Vb 1 \& struct C : public B, public A {}; .Ve .Sp G++ will place the \f(CW\*(C`A\*(C'\fR base class of \f(CW\*(C`C\*(C'\fR at a nonzero offset; it should be placed at offset zero. G++ mistakenly believes that the \&\f(CW\*(C`A\*(C'\fR data member of \f(CW\*(C`B\*(C'\fR is already at offset zero. .IP "*" 4 Names of template functions whose types involve \f(CW\*(C`typename\*(C'\fR or template template parameters can be mangled incorrectly. .Sp .Vb 2 \& template \& void f(typename Q::X) {} .Ve .Sp .Vb 2 \& template
