b9a2658a3e8bd13b0f9e7a8a440832a95b377216 - [libc++][C++03] Use `__cxx03/` headers in C++03 mode (#109002)

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/cstdalign

[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.

Wed, 30 Oct 2024 01:49:26 +0000

[libc++] Deprecate and remove meaningless `` headers (#111615)This PR deprecates ``, ``, ``, and `` in C++17 and "removes" them in C++20 by special deprecation warnings. `` is previously missing. This PR also tries to add them, and then deprecates and "removes" ``. Papers: - https://wg21.link/P0063R3 - https://wg21.link/P0619R4 Closes #99985. --------- Co-authored-by: Louis Dionne List of files: /llvm-project/libcxx/include/cstdalign
