24e70e3930724ce499ad05d669bfbc4423c542e0 - [libc++] Switch experimental library macros to 0/1 macros (#124030)

Fri, 24 Jan 2025 08:34:42 +0000

[libc++] Switch experimental library macros to 0/1 macros (#124030)This is a continuation of what's been started in #89178.As a drive-by, this also changes the PSTL macro to say `EXPERIMENTAL`instead of `INCOMPLETE`. List of files: /llvm-project/libcxx/include/syncstream

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/syncstream

[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.

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/syncstream

94e7c0b051c79fd56205f115771980f2e7812306 - [libc++] Remove get_temporary_buffer and return_temporary_buffer (#100914)

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/syncstream

87d56c59f52d033cd7c46d769338b9c47fea4929 - [libc++][modules] Guard carved-out headers more consistently (#108637)

Mon, 16 Sep 2024 12:15:38 +0000

[libc++][modules] Guard carved-out headers more consistently (#108637)Several headers that should not be provided when localization or threads are disabled were not guarded. That works until one tries to build with modules and these headers get pulled in. Note that this could be cleaned up further into something more systematic, but this patch solves the immediate problems I ran into with the monolithic modulemap and doesn't create any new inconsistency that wasn't already there.

7cc72a0a2ec22855572d96411febd4f2c4ac5a49 - Implement syncstream (p0053)

Tue, 05 Sep 2023 18:10:38 +0000

Implement syncstream (p0053)This patch implements `std::basic_syncbuf` and `std::basic_osyncstream` as specified in paper p0053r7. ~~For ease of reviewing I am submitting this patch before submitting a patch for `std::basic_osyncstream`. ~~~~Please note, this patch is not 100% complete. I plan on adding more tests (see comments), specifically I plan on adding tests for multithreading and synchronization.~~Edit: I decided that it would be far easier for me to keep track of this and make changes that affect both `std::basic_syncbuf` and `std::basic_osyncstream` if both were in one patch.The patch was originally written by @zoecarverImplements- P0053R7 - C++ Synchronized Buffered Ostream- LWG-3127 basic_osyncstream::rdbuf needs a const_cast- LWG-3334 basic_osyncstream move assignment and destruction calls basic_syncbuf::emit() twice- LWG-3570 basic_osyncstream::emit should be an unformatted output function- LWG-3867 Should std::basic_osyncstream's move assignment operator be noexcept?Reviewed By: ldionne, #libcDifferential Revision: https://reviews.llvm.org/D67086 List of files: /llvm-project/libcxx/include/syncstream
