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/strstream

e2c2ffbe7a1b5d9e32a2ce64279475b50c4cba5b - [libc++][NFC] Run clang-format on libcxx/include again (#95874)

Tue, 18 Jun 2024 13:13:45 +0000

[libc++][NFC] Run clang-format on libcxx/include again (#95874)As time went by, a few files have become mis-formatted w.r.t. clang-format. This was made worse by the fact that formatting was not being enforced in extensionless headers. This commit simply brings all of libcxx/include in-line with clang-format again. We might have to do this from time to time as we update our clang-format version, but frankly this is really low effort now that we've formatted everything once.

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/strstream

7b4622514d232ce5f7110dd8b20d90e81127c467 - [libc++] Fix missing and incorrect push/pop macros (#79204)

Thu, 25 Jan 2024 20:48:46 +0000

[libc++] Fix missing and incorrect push/pop macros (#79204)We recently noticed that the unwrap_iter.h file was pushing macros, but it was pushing them again instead of popping them at the end of the file. This led to libc++ basically swallowing any custom definition of these macros in user code: #define min HELLO #include // min is not HELLO anymore, it's not defined While investigating this issue, I noticed that our push/pop pragmas were actually entirely wrong too. Indeed, instead of pushing macros like `move`, we'd push `move(int, int)` in the pragma, which is not a valid macro name. As a result, we would not actually push macros like `move` -- instead we'd simply undefine them. This led to the following code not working: #define move HELLO #include // move is not HELLO anymore Fixing the pragma push/pop incantations led to a cascade of issues because we use identifiers like `move` in a large number of places, and all of these headers would now need to do the push/pop dance. This patch fixes all these issues. First, it adds a check that we don't swallow important names like min, max, move or refresh as explained above. This is done by augmenting the existing system_reserved_names.gen.py test to also check that the macros are what we expect after including each header. Second, it fixes the push/pop pragmas to work properly and adds missing pragmas to all the files I could detect a failure in via the newly added test. rdar://121365472 List of files: /llvm-project/libcxx/include/strstream

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.

[libc++] Ensure that all public C++ headers include <__assert>This patch changes the requirement for getting the declaration of theassertion handler from including <__assert> to including any publicC++ header of the library. Note that C compatibility headers areexcluded because we don't implement all the C headers ourselves --some of them are taken straight from the C library, like assert.h.It also adds a generated test to check it. Furthermore, this newgenerated test is designed in a way that will make it possible toreplace almost all the existing test-generation scripts with thissystem in upcoming patches.Differential Revision: https://reviews.llvm.org/D122506 List of files: /llvm-project/libcxx/include/strstream
