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/typeinfo

ba87515fea90b5d55836a8e3be63a7e683ce299d - [libc++][RFC] Always define internal feature test macros (#89178)

Sat, 12 Oct 2024 07:49:52 +0000

[libc++][RFC] Always define internal feature test macros (#89178)Currently, the library-internal feature test macros are only defined if the feature is not available, and always have the prefix `_LIBCPP_HAS_NO_`. This patch changes that, so that they are always defined and have the prefix `_LIBCPP_HAS_` instead. This changes the canonical use of these macros to `#if _LIBCPP_HAS_FEATURE`, which means that using an undefined macro (e.g. due to a missing include) is diagnosed now. While this is rather unlikely currently, a similar change in `<__configuration/availability.h>` caught a few bugs. This also improves readability, since it removes the double-negation of `#ifndef _LIBCPP_HAS_NO_FEATURE`. The current patch only touches the macros defined in `<__config>`. If people are happy with this approach, I'll make a follow-up PR to also change the macros defined in `<__config_site>`. List of files: /llvm-project/libcxx/include/typeinfo

d6832a611a7c4ec36f08b1cfe9af850dad32da2e - [libc++][modules] Modularize (#107254)

Thu, 05 Sep 2024 12:28:33 +0000

[libc++][modules] Modularize (#107254)Many headers include `` just for size_t, and pulling in additional content (e.g. the traits used for std::byte) is unnecessary. To solve this problem, this patch splits up `` into subcomponents so that headers can include only the parts that they actually require. This has the added benefit of making the modules build a lot stricter with respect to IWYU, and also providing a canonical location where we define `std::size_t` and friends (which were previously defined in multiple headers like `` and ``). After this patch, there's still many places in the codebase where we include `` when `<__cstddef/size_t.h>` would be sufficient. This patch focuses on removing `` includes from __type_traits to make these headers non-circular with ``. Additional refactorings can be tackled separately.

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/typeinfo

Mon, 22 Jan 2024 15:12:41 +0000

[libc++abi] Implement __cxa_init_primary_exception and use it to optimize std::make_exception_ptr (#65534)This patch implements __cxa_init_primary_exception, an extension to the Itanium C++ ABI. This extension is already present in both libsupc++ and libcxxrt. This patch also starts making use of this function in std::make_exception_ptr: instead of going through a full throw/catch cycle, we are now able to initialize an exception directly, thus making std::make_exception_ptr around 30x faster.

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.

4c198542226223f6a5c5511a1f89b37d15ee10b9 - [libc++] Rename _LIBCPP_INLINE_VISIBILITY to _LIBCPP_HIDE_FROM_ABI (#74095)

Mon, 04 Dec 2023 15:25:14 +0000

[libc++] Rename _LIBCPP_INLINE_VISIBILITY to _LIBCPP_HIDE_FROM_ABI (#74095)In preparation for running clang-format on the whole code base, we are also removing mentions of the legacy _LIBCPP_INLINE_VISIBILITY macro in favor of the newer _LIBCPP_HIDE_FROM_ABI. We're still leaving the definition of _LIBCPP_INLINE_VISIBILITY to avoid creating needless breakage in case some older patches are checked-in with mentions of the old macro. After we branch for LLVM 18, we can do another pass to clean up remaining uses of the macro that might have gotten introduced by mistake (if any) and remove the macro itself at the same time. This is just a minor convenience to smooth out the transition as much as possible. See https://discourse.llvm.org/t/rfc-clang-formatting-all-of-libc-once-and-for-all for the clang-format proposal.

[libc++] Remove availability annotations which can never be triggered (#69226)According to https://developer.apple.com/support/xcode/, quite a few of our availability macros don't do anything anymore, so we might as well remove them to clean up the code a bit.

[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. The places where we don't check for `_LIBCPP_HIDE_FROM_ABI` are classes for which we have an instantiation in the library.Reviewed By: ldionne, Mordante, #libcSpies: jplehr, mikhail.ramalho, sstefan1, libcxx-commits, krytarowski, miyuki, smeenaiDifferential Revision: https://reviews.llvm.org/D142332 List of files: /llvm-project/libcxx/include/typeinfo
