de4a57cb - [libc++] Re-add transitive includes that had been removed since LLVM 14

Mon, 27 Jun 2022 19:53:41 +0000

[libc++] Re-add transitive includes that had been removed since LLVM 14This commit re-adds transitive includes that had been removed by4cd04d1687f1, c36870c8e79c, a83f4b9cda57, 1458458b558d, 2e2f3158c604,and 489637e66dd3. This should cover almost all the includes that hadbeen removed since LLVM 14 and that would contribute to breaking usercode when releasing LLVM 15.It is possible to disable the inclusion of these headers by defining_LIBCPP_REMOVE_TRANSITIVE_INCLUDES. The intent is that vendors willenable that macro and start fixing downstream issues immediately. Wecan then remove the macro (and the transitive includes) by default ina future release. That way, we will break users only once by removingtransitive includes in bulk instead of doing it bit by bit a everyrelease, which is more disruptive for users.Note 1: The set of headers to re-add was found by re-generating the transitive include test on a checkout of release/14.x, which provided the list of all transitive includes we used to provide.Note 2: Several includes of , , and have been added in this commit. These transitive inclusions were added when we implemented boyer_moore_searcher in .Note 3: This is a best effort patch to try and resolve downstream breakage caused since branching LLVM 14. I wasn't able to perfectly mirror transitive includes in LLVM 14 for a few headers, so I added a release note explaining it. To summarize, adding boyer_moore_searcher created a bunch of circular dependencies, so we have to break backwards compatibility in a few cases.Differential Revision: https://reviews.llvm.org/D128661 List of files: /llvm-project-15.0.7/libcxx/include/variant

385cc25a - [libc++] Ensure that all public C++ headers include <__assert>

Fri, 25 Mar 2022 16:55:36 +0000

[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-15.0.7/libcxx/include/variant

3c6bd176 - [libc++] Rename identity to type_identity

Fri, 18 Mar 2022 16:49:02 +0000

[libc++] Rename __identity to __type_identityIn C++20 the type trait `type_identity` was introduced. For the same purpose there is `__identity` for pre-C++20 code. The name is confusing, because since C++20 there is also `identity`, which isn't a type trait.Reviewed By: ldionne, Mordante, #libcSpies: EricWF, libcxx-commitsDifferential Revision: https://reviews.llvm.org/D122017 List of files: /llvm-project-15.0.7/libcxx/include/variant

e39095a3 - [libc++] Define _LIBCPP_HAS_NO_PRAGMA_SYSTEM_HEADER whenever we enable warnings in the test suite

[libc++] Define _LIBCPP_HAS_NO_PRAGMA_SYSTEM_HEADER whenever we enable warnings in the test suiteThis should make CI consistent on all the compilers we support. Most ofthis patch is working around various warnings emitted by GCC in our codebase, which are now being shown when we compile the tests.After this patch, the whole test suite should be warning free on allcompilers we support and test, except for a few warnings on GCC thatwe silence explicitly until we figure out the proper fix for them.Differential Revision: https://reviews.llvm.org/D120684 List of files: /llvm-project-15.0.7/libcxx/include/variant

[libc++][NFCI] Remove uses of _LIBCPP_INLINE_VARAll supported compilers provide support for inline variables in C++17 now.Also, as a fly-by fix, replace some uses of _LIBCPP_CONSTEXPR by justconstexpr.The only exception in this patch is `std::ignore`, which is providedprior to C++17. Since it is defined in an anonymous namespace, it alwayshas internal linkage anyway, so using an inline variable there doesn'tprovide any benefit. Instead, `inline` was removed entirely on `std::ignore`.Differential Revision: https://reviews.llvm.org/D110243 List of files: /llvm-project-15.0.7/libcxx/include/variant
