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/memory

Mon, 16 Sep 2024 15:53:05 +0000

[libc++] Remove get_temporary_buffer and return_temporary_buffer (#100914)Works towards P0619R4 / #99985. The use of `std::get_temporary_buffer` and `std::return_temporary_buffer` are replaced with `unique_ptr`-based RAII buffer holder. Escape hatches: - `_LIBCPP_ENABLE_CXX20_REMOVED_TEMPORARY_BUFFER` restores `std::get_temporary_buffer` and `std::return_temporary_buffer`. Drive-by changes: - In ``, states that `get_temporary_buffer` is now removed, because `` is added in C++20. List of files: /llvm-project/libcxx/include/memory

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/memory

b18a46e35d69e4148a147256c70472d0a16e00e8 - [libc++][NFC] Add a few clang-format annotations (#74352)

Mon, 04 Dec 2023 20:17:31 +0000

[libc++][NFC] Add a few clang-format annotations (#74352)This is in preparation for clang-formatting the whole code base. These annotations are required either to avoid clang-format bugs or because the manually formatted code is significantly more readable than the clang-formatted alternative. All in all, it seems like very few annotations are required, which means that clang-format is doing a very good job in most cases. List of files: /llvm-project/libcxx/include/memory
