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/string_view

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/string_view

[libc++] Move everything related solely to _LIBCPP_ASSERT to its own fileThis is the first step towards disentangling the debug mode and assertionsin libc++. This patch doesn't make any functional change: it simply moves_LIBCPP_ASSERT-related stuff to its own file so as to make it clear thatlibc++ assertions and the debug mode are different things.

53406fb6 - [libc++] Guard much of std::ranges under _LIBCPP_HAS_NO_INCOMPLETE_RANGES.

Tue, 01 Feb 2022 21:52:02 +0000

[libc++] Guard much of std::ranges under _LIBCPP_HAS_NO_INCOMPLETE_RANGES.The logic here is that we are disabling *only* things in `std::ranges::`.Everything in `std::` is permitted, including `default_sentinel`, `contiguous_iterator`,`common_iterator`, `projected`, `swappable`, and so on. Then, we includeanything from `std::ranges::` that is required in order to make those thingswork: `ranges::swap`, `ranges::swap_ranges`, `input_range`, `ranges::begin`,`ranges::iter_move`, and so on. But then that's all. Everything else (includingnotably all of the "views" and the `std::views` namespace itself) is stilllocked up behind `_LIBCPP_HAS_NO_INCOMPLETE_RANGES`.Differential Revision: https://reviews.llvm.org/D118736 List of files: /llvm-project-15.0.7/libcxx/include/string_view
