[libc++] Inline basic_streambuf functions (#123379)Most of the `basic_streambuf` functions are really simple, which makesmost of the implementation when they are out of line boilerplate. List of files: /llvm-project/libcxx/include/streambuf

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/streambuf

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.

6b4b29f85900995b2a3b817548be4a534d46763b - [libc++][NFC] Remove unnecessary parens in static_asserts (#95605)

Tue, 18 Jun 2024 08:45:30 +0000

[libc++][NFC] Remove unnecessary parens in static_asserts (#95605)These were required a long time ago due to `static_assert` not actually being available in C++03. Now `static_assert` is simply mapped to `_Static_assert` in C++03, making the additional parens unnecessary. List of files: /llvm-project/libcxx/include/streambuf

[libc++][RFC] Only include what is required by-version in the umbrella headers (#83740)This is a relatively low cost way of reducing the include sizes in older language modes compared to the effect.

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/streambuf

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.

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.

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/streambuf

9d16cbc5c8bdf976287cc97c7d95d115496e3077 - [libc++] Adds more forward declaration headers.

Thu, 20 Apr 2023 19:03:40 +0000

[libc++] Adds more forward declaration headers.The module validation script of D144994 validate whether the contents ofan include match its module. An include is the set of files matching thepattern:- foo- foo/*.- __fwd/foo.hSeveral declarations of the stream headers are in the header iosfwd.This gives issue using the validation script. Adding iosfwd to the setof matching files gives too many declarations. For example whenvalidating the fstream header it will pull in declarations of theistream header. Instead if writing a set of filters the headers aregranularized into smaller headers containing the expected declarations.Reviewed By: #libc, ldionneDifferential Revision: https://reviews.llvm.org/D148927 List of files: /llvm-project/libcxx/include/streambuf
