These macros work by changing the visibility and inlining characteristics of the symbols they are applied to. Visibility Macros ================= **_LIBCPP_HIDDEN** Mark a symbol as hidden so it will not be exported from shared libraries. **_LIBCPP_FUNC_VIS** Mark a symbol as being exported by the libc++ library. This attribute must be applied to the declaration of all functions exported by the libc++ dylib. **_LIBCPP_EXTERN_VIS** Mark a symbol as being exported by the libc++ library. This attribute may only be applied to objects defined in the libc++ library. On Windows this macro applies `dllimport`/`dllexport` to the symbol. On all other platforms this macro has no effect. **_LIBCPP_OVERRIDABLE_FUNC_VIS** Mark a symbol as being exported by the libc++ library, but allow it to be overridden locally. On non-Windows, this is equivalent to `_LIBCPP_FUNC_VIS`. This macro is applied to all `operator new` and `operator delete` overloads. **Windows Behavior**: Any symbol marked `dllimport` cannot be overridden locally, since `dllimport` indicates the symbol should be bound to a separate DLL. All `operator new` and `operator delete` overloads are required to be locally overridable, and therefore must not be marked `dllimport`. On Windows, this macro therefore expands to `__declspec(dllexport)` when building the library and has an empty definition otherwise. **_LIBCPP_INLINE_VISIBILITY** Mark a function as hidden and force inlining whenever possible. **_LIBCPP_ALWAYS_INLINE** A synonym for `_LIBCPP_INLINE_VISIBILITY` **_LIBCPP_TYPE_VIS** Mark a type's typeinfo, vtable and members as having default visibility. This attribute cannot be used on class templates. **_LIBCPP_TEMPLATE_VIS** Mark a type's typeinfo and vtable as having default visibility. This macro has no effect on the visibility of the type's member functions. **GCC Behavior**: GCC does not support Clang's `type_visibility(...)` attribute. With GCC the `visibility(...)` attribute is used and member functions are affected. **Windows Behavior**: DLLs do not support dllimport/export on class templates. The macro has an empty definition on this platform. **_LIBCPP_ENUM_VIS** Mark the typeinfo of an enum as having default visibility. This attribute should be applied to all enum declarations. **Windows Behavior**: DLLs do not support importing or exporting enumeration typeinfo. The macro has an empty definition on this platform. **GCC Behavior**: GCC un-hides the typeinfo for enumerations by default, even if `-fvisibility=hidden` is specified. Additionally applying a visibility attribute to an enum class results in a warning. The macro has an empty definition with GCC. **_LIBCPP_EXTERN_TEMPLATE_TYPE_VIS** Mark the member functions, typeinfo, and vtable of the type named in a `_LIBCPP_EXTERN_TEMPLATE` declaration as being exported by the libc++ library. This attribute must be specified on all extern class template declarations. This macro is used to override the `_LIBCPP_TEMPLATE_VIS` attribute specified on the primary template and to export the member functions produced by the explicit instantiation in the dylib. **GCC Behavior**: GCC ignores visibility attributes applied the type in extern template declarations and applying an attribute results in a warning. However since `_LIBCPP_TEMPLATE_VIS` is the same as `__attribute__((visibility("default"))` the visibility is already correct. The macro has an empty definition with GCC. **Windows Behavior**: `extern template` and `dllexport` are fundamentally - incompatible *on a template class* on Windows; the former suppresses + incompatible *on a class template* on Windows; the former suppresses instantiation, while the latter forces it. Specifying both on the same - declaration makes the template class be instantiated, which is not desirable + declaration makes the class template be instantiated, which is not desirable inside headers. This macro therefore expands to `dllimport` outside of libc++ but nothing inside of it (rather than expanding to `dllexport`); instead, the explicit instantiations themselves are marked as exported. Note that this - applies *only* to extern template *classes*. Extern template *functions* obey + applies *only* to extern *class* templates. Extern *function* templates obey regular import/export semantics, and applying `dllexport` directly to the - extern template declaration is the correct thing to do for them. + extern template declaration (i.e. using `_LIBCPP_FUNC_VIS`) is the correct + thing to do for them. **_LIBCPP_CLASS_TEMPLATE_INSTANTIATION_VIS** Mark the member functions, typeinfo, and vtable of an explicit instantiation of a class template as being exported by the libc++ library. This attribute - must be specified on all template class explicit instantiations. + must be specified on all class template explicit instantiations. It is only necessary to mark the explicit instantiation itself (as opposed to the extern template declaration) as exported on Windows, as discussed above. On all other platforms, this macro has an empty definition. **_LIBCPP_METHOD_TEMPLATE_IMPLICIT_INSTANTIATION_VIS** Mark a symbol as hidden so it will not be exported from shared libraries. This is intended specifically for method templates of either classes marked with `_LIBCPP_TYPE_VIS` or classes with an extern template instantiation declaration marked with `_LIBCPP_EXTERN_TEMPLATE_TYPE_VIS`. When building libc++ with hidden visibility, we want explicit template instantiations to export members, which is consistent with existing Windows behavior. We also want classes annotated with `_LIBCPP_TYPE_VIS` to export their members, which is again consistent with existing Windows behavior. Both these changes are necessary for clients to be able to link against a libc++ DSO built with hidden visibility without encountering missing symbols. An unfortunate side effect, however, is that method templates of classes either marked `_LIBCPP_TYPE_VIS` or with extern template instantiation declarations marked with `_LIBCPP_EXTERN_TEMPLATE_TYPE_VIS` also get default visibility when instantiated. These methods are often implicitly instantiated inside other libraries which use the libc++ headers, and will therefore end up being exported from those libraries, since those implicit instantiations will receive default visibility. This is not acceptable for libraries that wish to control their visibility, and led to PR30642. Consequently, all such problematic method templates are explicitly marked either hidden (via this macro) or inline, so that they don't leak into client libraries. The problematic methods were found by running `bad-visibility-finder `_ against the libc++ headers after making `_LIBCPP_TYPE_VIS` and `_LIBCPP_EXTERN_TEMPLATE_TYPE_VIS` expand to default visibility. **_LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY** Mark a member function of a class template as visible and always inline. This macro should only be applied to member functions of class templates that are externally instantiated. It is important that these symbols are not marked as hidden as that will prevent the dylib definition from being found. This macro is used to maintain ABI compatibility for symbols that have been historically exported by the libc++ library but are now marked inline. **_LIBCPP_EXCEPTION_ABI** Mark the member functions, typeinfo, and vtable of the type as being exported by the libc++ library. This macro must be applied to all *exception types*. Exception types should be defined directly in namespace `std` and not the versioning namespace. This allows throwing and catching some exception types between libc++ and libstdc++.

libc++ C++1z Status

In November 2014, the C++ standard committee created a draft for the next version of the C++ standard, known here as "C++1z" (probably to be C++17).

In February 2017, the C++ standard committee approved this draft, and sent it to ISO for approval as C++17

This page shows the status of libc++; the status of clang's support of the language features is here.

The groups that have contributed papers:

  • LWG - Library working group
  • CWG - Core Language Working group
  • SG1 - Study group #1 (Concurrency working group)

libc++ C++2a Status

+ + +

In July 2017, the C++ standard committee created a draft for the next version of the C++ standard, known here as "C++2a" (probably to be C++20).

+

This page shows the status of libc++; the status of clang's support of the language features is here.

+ +

The groups that have contributed papers: +

    +
  • LWG - Library working group
    • +
  • CWG - Core Language Working group

"libc++" C++ Standard Library

libc++ is a new implementation of the C++ standard library, targeting C++11.

All of the code in libc++ is dual licensed under the MIT license and the UIUC License (a BSD-like license).

New Documentation Coming Soon!

Looking for documentation on how to use, build and test libc++? If so checkout the new libc++ documentation.

Click here for the new libc++ documentation.

Features and Goals

  • Correctness as defined by the C++11 standard.
  • Fast execution.
  • Minimal memory use.
  • Fast compile times.
  • ABI compatibility with gcc's libstdc++ for some low-level features such as exception objects, rtti and memory allocation.
  • Extensive unit tests.

Why a new C++ Standard Library for C++11?

After its initial introduction, many people have asked "why start a new library instead of contributing to an existing library?" (like Apache's libstdcxx, GNU's libstdc++, STLport, etc). There are many contributing reasons, but some of the major ones are:

  • From years of experience (including having implemented the standard library before), we've learned many things about implementing the standard containers which require ABI breakage and fundamental changes to how they are implemented. For example, it is generally accepted that building std::string using the "short string optimization" instead of using Copy On Write (COW) is a superior approach for multicore machines (particularly in C++11, which has rvalue references). Breaking ABI compatibility with old versions of the library was determined to be critical to achieving the performance goals of libc++.

  • Mainline libstdc++ has switched to GPL3, a license which the developers of libc++ cannot use. libstdc++ 4.2 (the last GPL2 version) could be independently extended to support C++11, but this would be a fork of the codebase (which is often seen as worse for a project than starting a new independent one). Another problem with libstdc++ is that it is tightly integrated with G++ development, tending to be tied fairly closely to the matching version of G++.

  • STLport and the Apache libstdcxx library are two other popular candidates, but both lack C++11 support. Our experience (and the experience of libstdc++ developers) is that adding support for C++11 (in particular rvalue references and move-only types) requires changes to almost every class and function, essentially amounting to a rewrite. Faced with a rewrite, we decided to start from scratch and evaluate every design decision from first principles based on experience.

    Further, both projects are apparently abandoned: STLport 5.2.1 was released in Oct'08, and STDCXX 4.2.1 in May'08.

Platform Support

libc++ is known to work on the following platforms, using g++-4.2 and clang (lack of C++11 language support disables some functionality). Note that functionality provided by <atomic> is only functional with clang.

  • Mac OS X i386
  • Mac OS X x86_64
  • FreeBSD 10+ i386
  • FreeBSD 10+ x86_64
  • FreeBSD 10+ ARM

Current Status

libc++ is a 100% complete C++11 implementation on Apple's OS X.

LLVM and Clang can self host in C++ and C++11 mode with libc++ on Linux.

libc++ is also a 100% complete C++14 implementation. A list of new features and changes for C++14 can be found here.

A list of features and changes for the next C++ standard, known here as "C++1z" (probably to be C++17) can be found here.

+

A list of features and changes for the C++ standard beyond C++17, known here as + "C++2a" (probably to be C++20) can be found here.

Implementation of the post-c++14 Technical Specifications is in progress. A list of features and the current status of these features can be found here.

Build Bots

The latest libc++ build results can be found at the following locations.

Get it and get involved!

First please review our Developer's Policy. The documentation for building and using libc++ can be found below.

Notes and Known Issues

  • Building libc++ with -fno-rtti is not supported. However linking against it with -fno-rtti is supported.
  • On OS X v10.8 and older the CMake option -DLIBCXX_LIBCPPABI_VERSION="" must be used during configuration.

Send discussions to the clang mailing list.

Bug reports and patches

If you think you've found a bug in libc++, please report it using the LLVM Bugzilla. If you're not sure, you can post a message to the cfe-dev mailing list or on IRC. Please include "libc++" in your subject.

If you want to contribute a patch to libc++, the best place for that is Phabricator. Please include [libc++] in the subject and add cfe-commits as a subscriber.

Comments about the issues

  • 2444 -
  • 2593 -
  • 2597 - I think we do this already; probably needs tests
  • 2783 - should be easy to change; needs tests
  • 2932 - We're not doing the parallel algorithms yet.
  • 2937 - Implemented with tests. The PR LGTM (Eric)
  • 2940 - We haven't implemented result_of yet, but I don't think that this will require any changes.
  • 2942 - all of our owner_before overloads are already noexcept; just need to update the tests.
  • 2954 - I don't think there's anything to do here.
  • 2961 - We haven't implemented the PMR stuff yet.
  • 2966 - Wording cleanup; no code or test changes needed.
  • 2974 - I did this in r305196. Tests added in 306580
