It can be used to debug three types of failures: optimizer crashes, miscompilations by optimizers, or bad native code generation (including problems in the static and JIT compilers). It aims to reduce large test cases to small, useful ones. For more information on the design and inner workings of \fBbugpoint\fP, as well as advice for using bugpoint, see \fIllvm/docs/Bugpoint.html\fP in the LLVM distribution. .SH OPTIONS .sp \fB\-\-additional\-so\fP \fIlibrary\fP .INDENT 0.0 .INDENT 3.5 Load the dynamic shared object \fIlibrary\fP into the test program whenever it is run. This is useful if you are debugging programs which depend on non\-LLVM libraries (such as the X or curses libraries) to run. .UNINDENT .UNINDENT .sp \fB\-\-append\-exit\-code\fP=\fI{true,false}\fP .INDENT 0.0 .INDENT 3.5 Append the test programs exit code to the output file so that a change in exit code is considered a test failure. Defaults to false. .UNINDENT .UNINDENT .sp \fB\-\-args\fP \fIprogram args\fP .INDENT 0.0 .INDENT 3.5 Pass all arguments specified after \fB\-\-args\fP to the test program whenever it runs. Note that if any of the \fIprogram args\fP start with a "\fB\-\fP", you should use: .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C bugpoint [bugpoint args] \-\-args \-\- [program args] .ft P .fi .UNINDENT .UNINDENT .sp The "\fB\-\-\fP" right after the \fB\-\-args\fP option tells \fBbugpoint\fP to consider any options starting with "\fB\-\fP" to be part of the \fB\-\-args\fP option, not as options to \fBbugpoint\fP itself. .UNINDENT .UNINDENT .sp \fB\-\-tool\-args\fP \fItool args\fP .INDENT 0.0 .INDENT 3.5 Pass all arguments specified after \fB\-\-tool\-args\fP to the LLVM tool under test (\fBllc\fP, \fBlli\fP, etc.) whenever it runs. You should use this option in the following way: .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C bugpoint [bugpoint args] \-\-tool\-args \-\- [tool args] .ft P .fi .UNINDENT .UNINDENT .sp The "\fB\-\-\fP" right after the \fB\-\-tool\-args\fP option tells \fBbugpoint\fP to consider any options starting with "\fB\-\fP" to be part of the \fB\-\-tool\-args\fP option, not as options to \fBbugpoint\fP itself. (See \fB\-\-args\fP, above.) .UNINDENT .UNINDENT .sp \fB\-\-safe\-tool\-args\fP \fItool args\fP .INDENT 0.0 .INDENT 3.5 Pass all arguments specified after \fB\-\-safe\-tool\-args\fP to the "safe" execution tool. .UNINDENT .UNINDENT .sp \fB\-\-gcc\-tool\-args\fP \fIgcc tool args\fP .INDENT 0.0 .INDENT 3.5 Pass all arguments specified after \fB\-\-gcc\-tool\-args\fP to the invocation of \fBgcc\fP\&. .UNINDENT .UNINDENT .sp \fB\-\-opt\-args\fP \fIopt args\fP .INDENT 0.0 .INDENT 3.5 Pass all arguments specified after \fB\-\-opt\-args\fP to the invocation of \fBopt\fP\&. .UNINDENT .UNINDENT .sp \fB\-\-disable\-{dce,simplifycfg}\fP .INDENT 0.0 .INDENT 3.5 Do not run the specified passes to clean up and reduce the size of the test program. By default, \fBbugpoint\fP uses these passes internally when attempting to reduce test programs. If you\(aqre trying to find a bug in one of these passes, \fBbugpoint\fP may crash. .UNINDENT .UNINDENT .sp \fB\-\-enable\-valgrind\fP .INDENT 0.0 .INDENT 3.5 Use valgrind to find faults in the optimization phase. This will allow bugpoint to find otherwise asymptomatic problems caused by memory mis\-management. .UNINDENT .UNINDENT .sp \fB\-find\-bugs\fP .INDENT 0.0 .INDENT 3.5 Continually randomize the specified passes and run them on the test program until a bug is found or the user kills \fBbugpoint\fP\&. .UNINDENT .UNINDENT .sp \fB\-help\fP .INDENT 0.0 .INDENT 3.5 Print a summary of command line options. .UNINDENT .UNINDENT .sp \fB\-\-input\fP \fIfilename\fP .INDENT 0.0 .INDENT 3.5 Open \fIfilename\fP and redirect the standard input of the test program, whenever it runs, to come from that file. .UNINDENT .UNINDENT .sp \fB\-\-load\fP \fIplugin\fP .INDENT 0.0 .INDENT 3.5 Load the dynamic object \fIplugin\fP into \fBbugpoint\fP itself. This object should register new optimization passes. Once loaded, the object will add new command line options to enable various optimizations. To see the new complete list of optimizations, use the \fB\-help\fP and \fB\-\-load\fP options together; for example: .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C bugpoint \-\-load myNewPass.so \-help .ft P .fi .UNINDENT .UNINDENT .UNINDENT .UNINDENT .sp \fB\-\-mlimit\fP \fImegabytes\fP .INDENT 0.0 .INDENT 3.5 Specifies an upper limit on memory usage of the optimization and codegen. Set to zero to disable the limit. .UNINDENT .UNINDENT .sp \fB\-\-output\fP \fIfilename\fP .INDENT 0.0 .INDENT 3.5 Whenever the test program produces output on its standard output stream, it should match the contents of \fIfilename\fP (the "reference output"). If you do not use this option, \fBbugpoint\fP will attempt to generate a reference output by compiling the program with the "safe" backend and running it. .UNINDENT .UNINDENT .sp \fB\-\-run\-{int,jit,llc,custom}\fP .INDENT 0.0 .INDENT 3.5 Whenever the test program is compiled, \fBbugpoint\fP should generate code for it using the specified code generator. These options allow you to choose the interpreter, the JIT compiler, the static native code compiler, or a custom command (see \fB\-\-exec\-command\fP) respectively. .UNINDENT .UNINDENT .sp \fB\-\-safe\-{llc,custom}\fP .INDENT 0.0 .INDENT 3.5 When debugging a code generator, \fBbugpoint\fP should use the specified code generator as the "safe" code generator. This is a known\-good code generator used to generate the "reference output" if it has not been provided, and to compile portions of the program that as they are excluded from the testcase. These options allow you to choose the static native code compiler, or a custom command, (see \fB\-\-exec\-command\fP) respectively. The interpreter and the JIT backends cannot currently be used as the "safe" backends. .UNINDENT .UNINDENT .sp \fB\-\-exec\-command\fP \fIcommand\fP .INDENT 0.0 .INDENT 3.5 This option defines the command to use with the \fB\-\-run\-custom\fP and \fB\-\-safe\-custom\fP options to execute the bitcode testcase. This can be useful for cross\-compilation. .UNINDENT .UNINDENT .sp \fB\-\-compile\-command\fP \fIcommand\fP .INDENT 0.0 .INDENT 3.5 This option defines the command to use with the \fB\-\-compile\-custom\fP option to compile the bitcode testcase. This can be useful for testing compiler output without running any link or execute stages. To generate a reduced unit test, you may add CHECK directives to the testcase and pass the name of an executable compile\-command script in this form: .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C #!/bin/sh llc "$@" not FileCheck [bugpoint input file].ll < bugpoint\-test\-program.s .ft P .fi .UNINDENT .UNINDENT .sp This script will "fail" as long as FileCheck passes. So the result will be the minimum bitcode that passes FileCheck. .UNINDENT .UNINDENT .sp \fB\-\-safe\-path\fP \fIpath\fP .INDENT 0.0 .INDENT 3.5 This option defines the path to the command to execute with the \fB\-\-safe\-{int,jit,llc,custom}\fP option. .UNINDENT .UNINDENT .SH EXIT STATUS .sp If \fBbugpoint\fP succeeds in finding a problem, it will exit with 0.

It archives several files together into a single file. The intent for this is to produce archive libraries by LLVM bitcode that can be linked into an LLVM program. However, the archive can contain any kind of file. By default, \fBllvm\-ar\fP generates a symbol table that makes linking faster because only the symbol table needs to be consulted, not each individual file member of the archive. .sp The \fBllvm\-ar\fP command can be used to \fIread\fP SVR4, GNU and BSD style archive files. However, right now it can only write in the GNU format. If an SVR4 or BSD style archive is used with the \fBr\fP (replace) or \fBq\fP (quick update) operations, the archive will be reconstructed in GNU format. .sp Here\(aqs where \fBllvm\-ar\fP departs from previous \fBar\fP implementations: .sp \fISymbol Table\fP .INDENT 0.0 .INDENT 3.5 Since \fBllvm\-ar\fP supports bitcode files. The symbol table it creates is in GNU format and includes both native and bitcode files. .UNINDENT .UNINDENT .sp \fILong Paths\fP .INDENT 0.0 .INDENT 3.5 Currently \fBllvm\-ar\fP can read GNU and BSD long file names, but only writes archives with the GNU format. .UNINDENT .UNINDENT .SH OPTIONS .sp The options to \fBllvm\-ar\fP are compatible with other \fBar\fP implementations. However, there are a few modifiers (\fIR\fP) that are not found in other \fBar\fP implementations. The options to \fBllvm\-ar\fP specify a single basic operation to perform on the archive, a variety of modifiers for that operation, the name of the archive file, and an optional list of file names. These options are used to determine how \fBllvm\-ar\fP should process the archive file. .sp The Operations and Modifiers are explained in the sections below. The minimal set of options is at least one operator and the name of the archive. Typically archive files end with a \fB\&.a\fP suffix, but this is not required. Following the \fIarchive\-name\fP comes a list of \fIfiles\fP that indicate the specific members of the archive to operate on. If the \fIfiles\fP option is not specified, it generally means either "none" or "all" members, depending on the operation. .SS Operations .sp d .INDENT 0.0 .INDENT 3.5 Delete files from the archive. No modifiers are applicable to this operation. The \fIfiles\fP options specify which members should be removed from the archive. It is not an error if a specified file does not appear in the archive. If no \fIfiles\fP are specified, the archive is not modified. .UNINDENT .UNINDENT .sp m[abi] .INDENT 0.0 .INDENT 3.5 Move files from one location in the archive to another. The \fIa\fP, \fIb\fP, and \fIi\fP modifiers apply to this operation. The \fIfiles\fP will all be moved to the location given by the modifiers. If no modifiers are used, the files will be moved to the end of the archive. If no \fIfiles\fP are specified, the archive is not modified. .UNINDENT .UNINDENT .sp p .INDENT 0.0 .INDENT 3.5 Print files to the standard output. This operation simply prints the \fIfiles\fP indicated to the standard output. If no \fIfiles\fP are specified, the entire archive is printed. Printing bitcode files is ill\-advised as they might confuse your terminal settings. The \fIp\fP operation never modifies the archive. .UNINDENT .UNINDENT .sp q .INDENT 0.0 .INDENT 3.5 Quickly append files to the end of the archive. This operation quickly adds the \fIfiles\fP to the archive without checking for duplicates that should be removed first. If no \fIfiles\fP are specified, the archive is not modified. Because of the way that \fBllvm\-ar\fP constructs the archive file, its dubious whether the \fIq\fP operation is any faster than the \fIr\fP operation. .UNINDENT .UNINDENT .sp r[abu] .INDENT 0.0 .INDENT 3.5 Replace or insert file members. The \fIa\fP, \fIb\fP, and \fIu\fP modifiers apply to this operation. This operation will replace existing \fIfiles\fP or insert them at the end of the archive if they do not exist. If no \fIfiles\fP are specified, the archive is not modified. .UNINDENT .UNINDENT .sp t[v] .INDENT 0.0 .INDENT 3.5 Print the table of contents. Without any modifiers, this operation just prints the names of the members to the standard output. With the \fIv\fP modifier, \fBllvm\-ar\fP also prints out the file type (B=bitcode, S=symbol table, blank=regular file), the permission mode, the owner and group, the size, and the date. If any \fIfiles\fP are specified, the listing is only for those files. If no \fIfiles\fP are specified, the table of contents for the whole archive is printed. .UNINDENT .UNINDENT .sp x[oP] .INDENT 0.0 .INDENT 3.5 Extract archive members back to files. The \fIo\fP modifier applies to this operation. This operation retrieves the indicated \fIfiles\fP from the archive and writes them back to the operating system\(aqs file system. If no \fIfiles\fP are specified, the entire archive is extract. .UNINDENT .UNINDENT .SS Modifiers (operation specific) .sp The modifiers below are specific to certain operations. See the Operations section (above) to determine which modifiers are applicable to which operations. .sp [a] .INDENT 0.0 .INDENT 3.5 When inserting or moving member files, this option specifies the destination of the new files as being after the \fIrelpos\fP member. If \fIrelpos\fP is not found, the files are placed at the end of the archive. .UNINDENT .UNINDENT .sp [b] .INDENT 0.0 .INDENT 3.5 When inserting or moving member files, this option specifies the destination of the new files as being before the \fIrelpos\fP member. If \fIrelpos\fP is not found, the files are placed at the end of the archive. This modifier is identical to the \fIi\fP modifier. .UNINDENT .UNINDENT .sp [i] .INDENT 0.0 .INDENT 3.5 A synonym for the \fIb\fP option. .UNINDENT .UNINDENT .sp [o] .INDENT 0.0 .INDENT 3.5 When extracting files, this option will cause \fBllvm\-ar\fP to preserve the original modification times of the files it writes. .UNINDENT .UNINDENT .sp [u] .INDENT 0.0 .INDENT 3.5 When replacing existing files in the archive, only replace those files that have a time stamp than the time stamp of the member in the archive. .UNINDENT .UNINDENT .SS Modifiers (generic) .sp The modifiers below may be applied to any operation. .sp [c] .INDENT 0.0 .INDENT 3.5 For all operations, \fBllvm\-ar\fP will always create the archive if it doesn\(aqt exist. Normally, \fBllvm\-ar\fP will print a warning message indicating that the archive is being created. Using this modifier turns off that warning. .UNINDENT .UNINDENT .sp [s] .INDENT 0.0 .INDENT 3.5 This modifier requests that an archive index (or symbol table) be added to the archive. This is the default mode of operation. The symbol table will contain all the externally visible functions and global variables defined by all the bitcode files in the archive. .UNINDENT .UNINDENT .sp [S] .INDENT 0.0 .INDENT 3.5 This modifier is the opposite of the \fIs\fP modifier. It instructs \fBllvm\-ar\fP to not build the symbol table. If both \fIs\fP and \fIS\fP are used, the last modifier to occur in the options will prevail. .UNINDENT .UNINDENT .sp [v] .INDENT 0.0 .INDENT 3.5 This modifier instructs \fBllvm\-ar\fP to be verbose about what it is doing. Each editing operation taken against the archive will produce a line of output saying what is being done. .UNINDENT .UNINDENT .SH STANDARDS .sp The \fBllvm\-ar\fP utility is intended to provide a superset of the IEEE Std 1003.2 (POSIX.2) functionality for \fBar\fP\&. \fBllvm\-ar\fP can read both SVR4 and BSD4.4 (or Mac OS X) archives. If the \fBf\fP modifier is given to the \fBx\fP or \fBr\fP operations then \fBllvm\-ar\fP will write SVR4 compatible archives. Without this modifier, \fBllvm\-ar\fP will write BSD4.4 compatible archives that have long names immediately after the header and indicated using the "#1/ddd" notation for the name in the header. .SH FILE FORMAT .sp The file format for LLVM Archive files is similar to that of BSD 4.4 or Mac OSX archive files. In fact, except for the symbol table, the \fBar\fP commands on those operating systems should be able to read LLVM archive files. The details of the file format follow. .sp Each archive begins with the archive magic number which is the eight printable characters "!n" where n represents the newline character (0x0A). Following the magic number, the file is composed of even length members that begin with an archive header and end with a n padding character if necessary (to make the length even). Each file member is composed of a header (defined below), an optional newline\-terminated "long file name" and the contents of the file. .sp The fields of the header are described in the items below. All fields of the header contain only ASCII characters, are left justified and are right padded with space characters. .sp name \- char[16] .INDENT 0.0 .INDENT 3.5 This field of the header provides the name of the archive member. If the name is longer than 15 characters or contains a slash (/) character, then this field contains \fB#1/nnn\fP where \fBnnn\fP provides the length of the name and the \fB#1/\fP is literal. In this case, the actual name of the file is provided in the \fBnnn\fP bytes immediately following the header. If the name is 15 characters or less, it is contained directly in this field and terminated with a slash (/) character. .UNINDENT .UNINDENT .sp date \- char[12] .INDENT 0.0 .INDENT 3.5 This field provides the date of modification of the file in the form of a decimal encoded number that provides the number of seconds since the epoch (since 00:00:00 Jan 1, 1970) per Posix specifications. .UNINDENT .UNINDENT .sp uid \- char[6] .INDENT 0.0 .INDENT 3.5 This field provides the user id of the file encoded as a decimal ASCII string. This field might not make much sense on non\-Unix systems. On Unix, it is the same value as the st_uid field of the stat structure returned by the stat(2) operating system call. .UNINDENT .UNINDENT .sp gid \- char[6] .INDENT 0.0 .INDENT 3.5 This field provides the group id of the file encoded as a decimal ASCII string. This field might not make much sense on non\-Unix systems. On Unix, it is the same value as the st_gid field of the stat structure returned by the stat(2) operating system call. .UNINDENT .UNINDENT .sp mode \- char[8] .INDENT 0.0 .INDENT 3.5 This field provides the access mode of the file encoded as an octal ASCII string. This field might not make much sense on non\-Unix systems. On Unix, it is the same value as the st_mode field of the stat structure returned by the stat(2) operating system call. .UNINDENT .UNINDENT .sp size \- char[10] .INDENT 0.0 .INDENT 3.5 This field provides the size of the file, in bytes, encoded as a decimal ASCII string. .UNINDENT .UNINDENT .sp fmag \- char[2] .INDENT 0.0 .INDENT 3.5 This field is the archive file member magic number. Its content is always the two characters back tick (0x60) and newline (0x0A). This provides some measure utility in identifying archive files that have been corrupted. .UNINDENT .UNINDENT .sp offset \- vbr encoded 32\-bit integer .INDENT 0.0 .INDENT 3.5 The offset item provides the offset into the archive file where the bitcode member is stored that is associated with the symbol. The offset value is 0 based at the start of the first "normal" file member. To derive the actual file offset of the member, you must add the number of bytes occupied by the file signature (8 bytes) and the symbol tables. The value of this item is encoded using variable bit rate encoding to reduce the size of the symbol table. Variable bit rate encoding uses the high bit (0x80) of each byte to indicate if there are more bytes to follow. The remaining 7 bits in each byte carry bits from the value. The final byte does not have the high bit set. .UNINDENT .UNINDENT .sp length \- vbr encoded 32\-bit integer .INDENT 0.0 .INDENT 3.5 The length item provides the length of the symbol that follows. Like this \fIoffset\fP item, the length is variable bit rate encoded. .UNINDENT .UNINDENT .sp symbol \- character array .INDENT 0.0 .INDENT 3.5 The symbol item provides the text of the symbol that is associated with the \fIoffset\fP\&. The symbol is not terminated by any character. Its length is provided by the \fIlength\fP field. Note that is allowed (but unwise) to use non\-printing characters (even 0x00) in the symbol. This allows for multiple encodings of symbol names. .UNINDENT .UNINDENT .SH EXIT STATUS .sp If \fBllvm\-ar\fP succeeds, it will exit with 0. A usage error, results in an exit code of 1. A hard (file system typically) error results in an exit code of 2. Miscellaneous or unknown errors result in an exit code of 3. .SH SEE ALSO .sp ar(1) .SH AUTHOR Maintained by The LLVM Team (http://llvm.org/). .SH COPYRIGHT -2003-2014, LLVM Project +2003-2016, LLVM Project .\" Generated by docutils manpage writer. .

The tool reads a bitcode file (such as generated with the \fBllvm\-as\fP tool) and produces a statistical report on the contents of the bitcode file. The tool can also dump a low level but human readable version of the bitcode file. This tool is probably not of much interest or utility except for those working directly with the bitcode file format. Most LLVM users can just ignore this tool. .sp If \fIfilename\fP is omitted or is \fB\-\fP, then \fBllvm\-bcanalyzer\fP reads its input from standard input. This is useful for combining the tool into a pipeline. Output is written to the standard output. .SH OPTIONS .INDENT 0.0 .TP .B \-nodetails Causes \fBllvm\-bcanalyzer\fP to abbreviate its output by writing out only a module level summary.

This format is significantly different from LLVM assembly and provides details about the encoding of the bitcode file. .UNINDENT .INDENT 0.0 .TP .B \-verify Causes \fBllvm\-bcanalyzer\fP to verify the module produced by reading the bitcode. This ensures that the statistics generated are based on a consistent module. .UNINDENT .INDENT 0.0 .TP .B \-help Print a summary of command line options. .UNINDENT .SH EXIT STATUS .sp If \fBllvm\-bcanalyzer\fP succeeds, it will exit with 0.

It can be used to work with \fBgcov\fP\-style coverage or with \fBclang\fP\(aqs instrumentation based profiling. .sp If the program is invoked with a base name of \fBgcov\fP, it will behave as if the \fBllvm\-cov gcov\fP command were called. Otherwise, a command should be provided. .SH COMMANDS .INDENT 0.0 .IP \(bu 2 \fI\%gcov\fP .IP \(bu 2 \fI\%show\fP .IP \(bu 2 \fI\%report\fP .UNINDENT .SH GCOV COMMAND .SS SYNOPSIS .sp \fBllvm\-cov gcov\fP [\fIoptions\fP] \fISOURCEFILE\fP .SS DESCRIPTION .sp The \fBllvm\-cov gcov\fP tool reads code coverage data files and displays the coverage information for a specified source file. It is compatible with the \fBgcov\fP tool from version 4.2 of \fBGCC\fP and may also be compatible with some later versions of \fBgcov\fP\&. .sp To use \fBllvm\-cov gcov\fP, you must first build an instrumented version of your application that collects coverage data as it runs. Compile with the \fB\-fprofile\-arcs\fP and \fB\-ftest\-coverage\fP options to add the instrumentation. (Alternatively, you can use the \fB\-\-coverage\fP option, which includes both of those other options.) You should compile with debugging information (\fB\-g\fP) and without optimization (\fB\-O0\fP); otherwise, the coverage data cannot be accurately mapped back to the source code. .sp At the time you compile the instrumented code, a \fB\&.gcno\fP data file will be generated for each object file. These \fB\&.gcno\fP files contain half of the coverage data. The other half of the data comes from \fB\&.gcda\fP files that are generated when you run the instrumented program, with a separate \fB\&.gcda\fP file for each object file. Each time you run the program, the execution counts are summed into any existing \fB\&.gcda\fP files, so be sure to remove any old files if you do not want their contents to be included. .sp By default, the \fB\&.gcda\fP files are written into the same directory as the object files, but you can override that by setting the \fBGCOV_PREFIX\fP and \fBGCOV_PREFIX_STRIP\fP environment variables. The \fBGCOV_PREFIX_STRIP\fP variable specifies a number of directory components to be removed from the start of the absolute path to the object file directory. After stripping those directories, the prefix from the \fBGCOV_PREFIX\fP variable is added. These environment variables allow you to run the instrumented program on a machine where the original object file directories are not accessible, but you will then need to copy the \fB\&.gcda\fP files back to the object file directories where \fBllvm\-cov gcov\fP expects to find them. .sp Once you have generated the coverage data files, run \fBllvm\-cov gcov\fP for each main source file where you want to examine the coverage results. This should be run from the same directory where you previously ran the compiler. The results for the specified source file are written to a file named by appending a \fB\&.gcov\fP suffix. A separate output file is also created for each file included by the main source file, also with a \fB\&.gcov\fP suffix added. .sp The basic content of an \fB\&.gcov\fP output file is a copy of the source file with an execution count and line number prepended to every line. The execution count is shown as \fB\-\fP if a line does not contain any executable code. If a line contains code but that code was never executed, the count is displayed as \fB#####\fP\&. .SS OPTIONS .INDENT 0.0 .TP .B \-a, \-\-all\-blocks Display all basic blocks. If there are multiple blocks for a single line of source code, this option causes llvm\-cov to show the count for each block instead of just one count for the entire line. .UNINDENT .INDENT 0.0 .TP .B \-b, \-\-branch\-probabilities Display conditional branch probabilities and a summary of branch information. .UNINDENT .INDENT 0.0 .TP .B \-c, \-\-branch\-counts Display branch counts instead of probabilities (requires \-b). .UNINDENT .INDENT 0.0 .TP .B \-f, \-\-function\-summaries Show a summary of coverage for each function instead of just one summary for an entire source file. .UNINDENT .INDENT 0.0 .TP .B \-\-help Display available options (\-\-help\-hidden for more). .UNINDENT .INDENT 0.0 .TP .B \-l, \-\-long\-file\-names For coverage output of files included from the main source file, add the main file name followed by \fB##\fP as a prefix to the output file names. This can be combined with the \-\-preserve\-paths option to use complete paths for both the main file and the included file. .UNINDENT .INDENT 0.0 .TP .B \-n, \-\-no\-output Do not output any \fB\&.gcov\fP files. Summary information is still displayed. .UNINDENT .INDENT 0.0 .TP .B \-o=, \-\-object\-directory=, \-\-object\-file= Find objects in DIR or based on FILE\(aqs path. If you specify a particular object file, the coverage data files are expected to have the same base name with \fB\&.gcno\fP and \fB\&.gcda\fP extensions. If you specify a directory, the files are expected in that directory with the same base name as the source file. .UNINDENT .INDENT 0.0 .TP .B \-p, \-\-preserve\-paths Preserve path components when naming the coverage output files. In addition to the source file name, include the directories from the path to that file. The directories are separate by \fB#\fP characters, with \fB\&.\fP directories removed and \fB\&..\fP directories replaced by \fB^\fP characters. When used with the \-\-long\-file\-names option, this applies to both the main file name and the included file name. .UNINDENT .INDENT 0.0 .TP .B \-u, \-\-unconditional\-branches Include unconditional branches in the output for the \-\-branch\-probabilities option. .UNINDENT .INDENT 0.0 .TP .B \-version Display the version of llvm\-cov. .UNINDENT .SS EXIT STATUS .sp \fBllvm\-cov gcov\fP returns 1 if it cannot read input files. Otherwise, it exits with zero. .SH SHOW COMMAND .SS SYNOPSIS .sp \fBllvm\-cov show\fP [\fIoptions\fP] \-instr\-profile \fIPROFILE\fP \fIBIN\fP [\fISOURCES\fP] .SS DESCRIPTION .sp The \fBllvm\-cov show\fP command shows line by line coverage of a binary \fIBIN\fP using the profile data \fIPROFILE\fP\&. It can optionally be filtered to only show the coverage for the files listed in \fISOURCES\fP\&. .sp To use \fBllvm\-cov show\fP, you need a program that is compiled with instrumentation to emit profile and coverage data. To build such a program with \fBclang\fP use the \fB\-fprofile\-instr\-generate\fP and \fB\-fcoverage\-mapping\fP flags. If linking with the \fBclang\fP driver, pass \fB\-fprofile\-instr\-generate\fP to the link stage to make sure the necessary runtime libraries are linked in. .sp The coverage information is stored in the built executable or library itself, and this is what you should pass to \fBllvm\-cov show\fP as the \fIBIN\fP argument. The profile data is generated by running this instrumented program normally. When the program exits it will write out a raw profile file, typically called \fBdefault.profraw\fP, which can be converted to a format that is suitable for the \fIPROFILE\fP argument using the \fBllvm\-profdata merge\fP tool. .SS OPTIONS .INDENT 0.0 .TP .B \-show\-line\-counts Show the execution counts for each line. This is enabled by default, unless another \fB\-show\fP option is used. .UNINDENT .INDENT 0.0 .TP .B \-show\-expansions Expand inclusions, such as preprocessor macros or textual inclusions, inline in the display of the source file. .UNINDENT .INDENT 0.0 .TP .B \-show\-instantiations For source regions that are instantiated multiple times, such as templates in \fBC++\fP, show each instantiation separately as well as the combined summary. .UNINDENT .INDENT 0.0 .TP .B \-show\-regions Show the execution counts for each region by displaying a caret that points to the character where the region starts. .UNINDENT .INDENT 0.0 .TP .B \-show\-line\-counts\-or\-regions Show the execution counts for each line if there is only one region on the line, but show the individual regions if there are multiple on the line. .UNINDENT .INDENT 0.0 .TP .B \-use\-color[=VALUE] Enable or disable color output. By default this is autodetected. .UNINDENT .INDENT 0.0 .TP .B \-arch= If the covered binary is a universal binary, select the architecture to use.

It can optionally be filtered to only show the coverage for the files listed in \fISOURCES\fP\&. .sp If no source files are provided, a summary line is printed for each file in the coverage data.

It will usually print the results on standard output, but in a few cases, it will print output to standard error or generate a file with the analysis output, which is usually done when the output is meant for another program. .sp -While \fI\-analyze\fP is \fInot\fP given, \fBopt\fP attempts to produce an +While \fB\-analyze\fP is \fInot\fP given, \fBopt\fP attempts to produce an optimized output file. The optimizations available via \fBopt\fP depend upon what libraries were linked into it as well as any additional libraries that have been loaded with the \fI\%\-load\fP option. Use the \fI\%\-help\fP option to determine what optimizations you can use. .sp If \fBfilename\fP is omitted from the command line or is "\fB\-\fP", \fBopt\fP reads its input from standard input. Inputs can be in either the LLVM assembly language format (\fB\&.ll\fP) or the LLVM bitcode format (\fB\&.bc\fP). .sp If an output filename is not specified with the \fI\%\-o\fP option, \fBopt\fP writes its output to the standard output. .SH OPTIONS .INDENT 0.0 .TP .B \-f Enable binary output on terminals. Normally, \fBopt\fP will refuse to write raw bitcode output if the output stream is a terminal. With this option, \fBopt\fP will write raw bitcode regardless of the output device. .UNINDENT .INDENT 0.0 .TP .B \-help Print a summary of command line options. .UNINDENT .INDENT 0.0 .TP .B \-o Specify the output filename. .UNINDENT .INDENT 0.0 .TP .B \-S Write output in LLVM intermediate language (instead of bitcode). .UNINDENT .INDENT 0.0 .TP .B \-{passname} \fBopt\fP provides the ability to run any of LLVM\(aqs optimization or analysis passes in any order. The \fI\%\-help\fP option lists all the passes available. The order in which the options occur on the command line are the order in which they are executed (within pass constraints). .UNINDENT .INDENT 0.0 .TP .B \-disable\-inlining This option simply removes the inlining pass from the standard list. .UNINDENT .INDENT 0.0 .TP .B \-disable\-opt -This option is only meaningful when \fI\-std\-link\-opts\fP is given.
