So in the working draftlike N4892, we could find the coroutine components is defined in stdnamespace instead of std::experimental namespace.And the coroutine support in clang seems to be relatively stable. So Ithink it may be suitable to move the coroutine component into theexperiment namespace now.This patch would make clang lookup coroutine_traits in std namespacefirst. For the compatibility consideration, clang would lookup instd::experimental namespace if it can't find definitions in stdnamespace. So the existing codes wouldn't be break after updatecompiler.And in case the compiler found std::coroutine_traits andstd::experimental::coroutine_traits at the same time, it would emit anerror for it.The support for looking up std::experimental::coroutine_traits would beremoved in Clang16.Reviewed By: lxfind, QuuxplusoneDifferential Revision: https://reviews.llvm.org/D108696 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/coroutine-unhandled_exception-warning.cpp Thu, 04 Nov 2021 03:50:30 +0000 Chuanqi Xu <yedeng.yd@linux.alibaba.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/coroutine-unhandled_exception-warning.cpp#79f8b5f0 Revert "[Coroutines] [Clang] Look up coroutine component in std namespace first"This reverts commit 2fbd254aa46b, which broke the libc++ CI.

So Ithink it may be suitable to move the coroutine component into theexperiment namespace now.But move the coroutine component into the std namespace may be an breakchange. So I planned to split this change into two patch. One in clangand other in libcxx.This patch would make clang lookup coroutine_traits in std namespacefirst. For the compatibility consideration, clang would lookup instd::experimental namespace if it can't find definitions in stdnamespace and emit a warning in this case.

We also look at any returned datatype that requires explicit destruction, and check their destructors for noexcept.This patch does not check declarations with dependent types yet, which will be done in future patches.Updated all tests to add noexcept to the required functions, and added a dedicated test for this patch.This patch might start to cause existing codebase fail to compile because most people may not have been strict in taggingall the related functions noexcept.Reviewers: lewissbaker, modocache, junparserReviewed By: modocacheSubscribers: arphaman, junparser, cfe-commitsTags: #clangDifferential Revision: https://reviews.llvm.org/D82029 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/coroutine-unhandled_exception-warning.cpp Mon, 15 Jun 2020 23:27:41 +0000 Xun Li <xun@fb.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/coroutine-unhandled_exception-warning.cpp#29ff638c [coroutines] Improved diagnostics when unhandled_exception is missing in the promise_typeSummary: Now we helpfully provide a note pointing at the promise_type in question.Reviewers: EricWF, GorNishanovReviewed By: GorNishanovSubscribers: cfe-commitsDifferential Revision: https://reviews.llvm.org/D33481llvm-svn: 303752 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/coroutine-unhandled_exception-warning.cpp Wed, 24 May 2017 14:34:19 +0000 Gor Nishanov <GorNishanov@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/coroutine-unhandled_exception-warning.cpp#a9b3d097 Rename coroutine warning when unhandled_exception() is missingllvm-svn: 300513 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/coroutine-unhandled_exception-warning.cpp Mon, 17 Apr 2017 23:28:02 +0000 Eric Fiselier <eric@efcs.ca> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/coroutine-unhandled_exception-warning.cpp#a9fdb346 [coroutines] Implement unhandled_exception changes.Summary:This patch adopts the recent changes that renamed `set_exception(exception_pointer)` to `unhandled_exception()`. Additionally `unhandled_exception()` is now required, and so an error is emitted when exceptions are enabled but the promise type does not provide the member.When exceptions are disabled a warning is emitted instead of an error, The warning notes that the `unhandled_exception()` function is required when exceptions are enabled.Reviewers: rsmith, GorNishanov, aaron.ballman, majnemerReviewed By: GorNishanovSubscribers: mehdi_amini, cfe-commitsDifferential Revision: https://reviews.llvm.org/D30859llvm-svn: 298565 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/coroutine-unhandled_exception-warning.cpp Thu, 23 Mar 2017 00:33:33 +0000 Eric Fiselier <eric@efcs.ca>
