368faaca - [libc++] Revert "Protect users from relying on detail headers" & related changes

Mon, 28 Feb 2022 21:37:25 +0000

[libc++] Revert "Protect users from relying on detail headers" & related changesThis commit reverts 5aaefa51 (and also partly 7f285f48e77 and b6d75682f9,which were related to the original commit). As landed, 5aaefa51 hadunintended consequences on some downstream bots and didn't have propercoverage upstream due to a few subtle things. Implementing this issomething we should do in libc++, however we'll first need to addressa few issues listed in https://reviews.llvm.org/D106124#3349710.Differential Revision: https://reviews.llvm.org/D120683 List of files: /llvm-project-15.0.7/libcxx/include/__threading_support

5aaefa51 - [libcxx][modules] protects users from relying on detail headers

Fri, 25 Feb 2022 18:59:32 +0000

[libcxx][modules] protects users from relying on detail headerslibc++ has started splicing standard library headers into much morefine-grained content for maintainability. It's very likely that outdatedand naive tooling (some of which is outside of LLVM's scope) willsuggest users include things such as <__ranges/access.h> instead of, and Hyrum's law suggests that users will eventually begin torely on this without the help of tooling. As such, this commitintends to protect users from themselves, by making it a hard error foranyone outside of the standard library to include libc++ detail headers.Differential Revision: https://reviews.llvm.org/D106124 List of files: /llvm-project-15.0.7/libcxx/include/__threading_support

df51be85 - [libc++] Split a few utilities out of __threading_support

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/__threading_support

Thu, 16 Dec 2021 21:59:56 +0000

[libc++] Add a bunch of missing inline and _LIBCPP_HIDE_FROM_ABI in __threading_supportThe inline keyword is required on those functions because they are definedin the headers, so we need them to be inline to avoid ODR violations.While we're at it, slap _LIBCPP_HIDE_FROM_ABI on them because they areimplementation details and we don't want them to be part of our ABI underany circumstances.Differential Revision: https://reviews.llvm.org/D115906 List of files: /llvm-project-15.0.7/libcxx/include/__threading_support

92832e48 - [libc++] Enable when threads are disabled

Wed, 17 Nov 2021 15:59:31 +0000

[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/__threading_support

d0eaf753 - [libc++] Remove non-atomic "platform" semaphore implementations.

Mon, 20 Sep 2021 22:03:49 +0000

[libc++] Remove non-atomic "platform" semaphore implementations.These can't be made constexpr-constructible (constinit'able),so they aren't C++20-conforming. Also, the platform versions aregoing to be bigger than the atomic/futex version, so we'd havethe awkward situation that `semaphore<42>` could be bigger than`semaphore<43>`, and that's just silly.Differential Revision: https://reviews.llvm.org/D110110 List of files: /llvm-project-15.0.7/libcxx/include/__threading_support

[SystemZ][ZOS] Fix the usage of pthread_t within libc++This is the the minimal change introduced in [[ https://reviews.llvm.org/D88599 | D88599 ]] to unblock the controversial change and discussion of proper separation between thread from thread id which will continue in D88599.This patch will address the differences of definition of pthread_t on z/OS vs. Linux and other OS. Main trick to make the code work on z/OS relies on redefining libcpp_thread_id type and _LIBCPP_NULL_THREAD macro. This is necessary to separate initialization of libcxx_thread_id from the one of __libcxx_thread_t;Reviewed By: #libc, ldionneDifferential Revision: https://reviews.llvm.org/D91875 List of files: /llvm-project-15.0.7/libcxx/include/__threading_support
