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/thread

[libc++] Improve error messages for disabled modesWe should not surface CMake-level options like LIBCXX_ENABLE_FILESYSTEMto our users, since they don't know what it means. Instead, use a slightlymore general wording.Also, add an error in to improve the quality of errors for peopletrying to use when localization is disabled.Differential Revision: https://reviews.llvm.org/D125910 List of files: /llvm-project-15.0.7/libcxx/include/thread

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/thread

[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. Future patcheswill make it possible to enable assertions without enabling the debugmode.Differential Revision: https://reviews.llvm.org/D119769 List of files: /llvm-project-15.0.7/libcxx/include/thread

Mon, 10 Jan 2022 14:43:29 +0000

[libc++] Split a few utilities out of __threading_supportThis change is the basis for a further refactoring where I'm going tosplit up the various implementations we have in __threading_support tomake that code easier to understand.Note that I had to make __convert_to_timespec a template to breakcircular dependencies. Concretely, we never seem to use it with anythingother than ::timespec, but I am wary of hardcoding that assumption aspart of this change, since I suspect there's a reason for going throughthese hoops in the first place.Differential Revision: https://reviews.llvm.org/D116944 List of files: /llvm-project-15.0.7/libcxx/include/thread

cb8a0b07 - [libc++] [ranges] Introduce _LIBCPP_AUTO_CAST(x) for auto(x).

Tue, 14 Dec 2021 00:21:38 +0000

[libc++] [ranges] Introduce _LIBCPP_AUTO_CAST(x) for auto(x).Clang is gaining `auto(x)` support in D113393; sadly thereseems to be no feature-test macro for it. Zhihao is openinga core issue for that macro.Use `_LIBCPP_AUTO_CAST` where C++20 specifies we should use `auto(x)`;stop using `__decay_copy(x)` in those places.In fact, remove `__decay_copy` entirely. As of C++20, it's purelya paper specification tool signifying "Return just `x`, but it wasperfect-forwarded, so we understand you're going to have to callits move-constructor sometimes." I believe there's no reason we'dever need to do its operation explicitly in code.This heisenbugs away a test failure on MinGW; see D112214.Differential Revision: https://reviews.llvm.org/D115686 List of files: /llvm-project-15.0.7/libcxx/include/thread

[libc++] Enable when threads are disabledstd::atomic is, for the most part, just a thin veneer on top of compilerbuiltins. Hence, it should be available even when threads are not availableon the system, and in fact there has been requests for such support.This patch:- Moves __libcpp_thread_poll_with_backoff to its own header so it can be used in when threads are disabled.- Adds a dummy backoff policy for atomic polling that doesn't know about threads.- Adjusts the feature-test macros so they are provided even when threads are disabled.- Runs the tests when threads are disabled.rdar://77873569Differential Revision: https://reviews.llvm.org/D114109 List of files: /llvm-project-15.0.7/libcxx/include/thread
