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-seh.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-seh.cpp#79f8b5f0 Revert "[Coroutines] [Clang] Look up coroutine component in std namespace first"This reverts commit 2fbd254aa46b, which broke the libc++ CI.

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.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. So the existing codeswouldn't be break after update compiler.Test Plan: check-clang, check-libcxxReviewed By: lxfindDifferential Revision: https://reviews.llvm.org/D108696 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/coroutine-seh.cpp Fri, 03 Sep 2021 02:22:53 +0000 Chuanqi Xu <yedeng.yd@linux.alibaba.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/coroutine-seh.cpp#5b050e4a [coroutines] Wrap the body of the coroutine in try-catchSummary:If unhandled_exception member function is present in the coroutine promise,wrap the body of the coroutine in:```try { body} catch(...) { promise.unhandled_exception(); }```Reviewers: EricWF, rnk, rsmithReviewed By: rsmithSubscribers: cfe-commitsDifferential Revision: https://reviews.llvm.org/D31692llvm-svn: 303583 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/coroutine-seh.cpp Mon, 22 May 2017 22:33:17 +0000 Gor Nishanov <GorNishanov@gmail.com>
