Sat, 21 Dec 2024 12:01:48 +0000

[libc++][C++03] Use `__cxx03/` headers in C++03 mode (#109002)This patch implements the forwarding to frozen C++03 headers asdiscussed inhttps://discourse.llvm.org/t/rfc-freezing-c-03-headers-in-libc. In theRFC, we initially proposed selecting the right headers from the Clangdriver, however consensus seemed to steer towards handling this in thelibrary itself. This patch implements that direction.At a high level, the changes basically amount to making each publicheader look like this:```// inside #ifdef _LIBCPP_CXX03_LANG# include <__cxx03/vector>#else // normal content#endif```In most cases, public headers are simple umbrella headers so there isn'tmuch code in the #else branch. In other cases, the #else branch containsthe actual implementation of the header. List of files: /llvm-project/libcxx/include/thread

[libc++] Add #if 0 block to all the top-level headers (#119234)Including The frozen C++03 headers results in a lot of formattingchanges in the main headers, so this splits these changes into aseparate commit instead.This is part ofhttps://discourse.llvm.org/t/rfc-freezing-c-03-headers-in-libc.

ef51e617c43ef4248973f07e0a711f69d85c948c - [libc++] Handle _LIBCPP_HAS_NO_{THREADS,LOCALIZATION} consistently with other carve-outs (#98319)

Mon, 15 Jul 2024 14:11:23 +0000

[libc++] Handle _LIBCPP_HAS_NO_{THREADS,LOCALIZATION} consistently with other carve-outs (#98319)Previously, we would issue an #error when using a header that requires threading support or localization support in a configuration where that is disabled. This is unlike what we do for all the other carve outs like no-filesystem, no-wide-characters or no-random-device. Instead of issuing an #error, we normally just remove the problematic parts of the header. This patch makes the handling of no-localization and no-threads consistent with the other carve-outs. I dislike the fact that users won't get an explicit error message when trying to use e.g. ios in a build that doesn't support localization, but I think it is better to handle things consistently. Note that besides the consistency argument, the #error approach doesn't really work anyways since it would break down if we moved towards assuming the C locale only in the no-localization mode.

37dca605c9bd41732da010ee97ed15ad9585a37d - [libc++] Clean up includes of <__assert> (#80091)

Thu, 29 Feb 2024 15:12:22 +0000

[libc++] Clean up includes of <__assert> (#80091)Originally, we used __libcpp_verbose_abort to handle assertion failures. That function was declared from all public headers. Since we don't use that mechanism anymore, we don't need to declare __libcpp_verbose_abort from all public headers, and we can clean up a lot of unnecessary includes. This patch also moves the definition of the various assertion categories to the <__assert> header, since we now rely on regular IWYU for these assertion macros. rdar://105510916 List of files: /llvm-project/libcxx/include/thread

7162fd750ee5f786f3b9b7a7b26b72ee36ce772e - [libc++] Split the monolithic __threading_support header (#79654)

Tue, 30 Jan 2024 13:35:15 +0000

[libc++] Split the monolithic __threading_support header (#79654)The <__threading_support> header is a huge beast and it's really difficult to navigate. I find myself struggling to find what I want every time I have to open it, and I've been considering splitting it up for years for that reason. This patch aims not to contain any functional change. The various implementations of the threading base are simply moved to separate headers and then the individual headers are simplified in mechanical ways. For example, we used to have redundant declarations of all the functions at the top of `__threading_support`, and those are removed since they are not needed anymore. The various #ifdefs are also simplified and removed when they become unnecessary. Finally, this patch adds documentation for the API we expect from any threading implementation.

Tue, 16 Jan 2024 18:13:40 +0000

[libc++] Improves _LIBCPP_HAS_NO_THREADS guards. (#76624)Previously the header included several headers, possibly granularized threading headers. This could lead to build errors when these headers were incompatible with threading disabled. Now test the guard before inclusion. This matches the pattern used for no localization and no wide characters. Fixes: https://github.com/llvm/llvm-project/issues/76620 List of files: /llvm-project/libcxx/include/thread

9783f28cbb155e4a8d49c12e1c60ce14dcfaf0c7 - [libc++] Format the code base (#74334)

Mon, 18 Dec 2023 19:01:33 +0000

[libc++] Format the code base (#74334)This patch runs clang-format on all of libcxx/include and libcxx/src, in accordance with the RFC discussed at [1]. Follow-up patches will format the benchmarks, the test suite and remaining parts of the code. I'm splitting this one into its own patch so the diff is a bit easier to review. This patch was generated with: find libcxx/include libcxx/src -type f \ | grep -v 'module.modulemap.in' \ | grep -v 'CMakeLists.txt' \ | grep -v 'README.txt' \ | grep -v 'libcxx.imp' \ | grep -v '__config_site.in' \ | xargs clang-format -i A Git merge driver is available in libcxx/utils/clang-format-merge-driver.sh to help resolve merge and rebase issues across these formatting changes.

[libc++] Add hide_from_abi check for classesWe already have a clang-tidy check for making sure that `_LIBCPP_HIDE_FROM_ABI` is on free functions. This patch extends this to class members.
