Uncertain if this fix meets the bar to also be applied to the release branch.If accepted, I'll need someone with commit access to submit on my behalf.Reviewed By: royjacobson, aaron.ballman, erichkeaneDifferential Revision: https://reviews.llvm.org/D131730(cherry picked from commit 64f0f7e6460019a38fe2f1cbe4b9446a3268af18) List of files: /llvm-project-15.0.7/clang/test/SemaCXX/deprecated-builtins.cpp Sat, 13 Aug 2022 19:52:41 +0000 Zachary Henkel <zahen@microsoft.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/deprecated-builtins.cpp#0b89d1d5 [Sema] Add deprecation warnings for some compiler provided __has_* type traitsSome compiler provided type traits like __has_trivial_constructor have been documentedas deprecated for quite some time.Still, some people apparently still use them, even though mixing them with conceptsand with deleted functions leads to weird results. There's also disagreement about someedge cases between GCC (which Clang claims to follow) and MSVC.This patch adds deprecation warnings for the usage of those builtins, except for __has_trivial_destructorwhich doesn't have a GCC alternative.I made the warning on by default, so I had to silence it for some tests but it's not too many.Some (decade old) history of issues with those builtins:https://github.com/llvm/llvm-project/issues/18187https://github.com/llvm/llvm-project/issues/18559https://github.com/llvm/llvm-project/issues/22161https://github.com/llvm/llvm-project/issues/33063The abseil usage of them that triggered me to add this warning:https://github.com/abseil/abseil-cpp/issues/1201Weird interaction of those builtins with C++20's conditionally trivial special member functions:https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106085Reviewed By: #clang-language-wg, aaron.ballmanDifferential Revision: https://reviews.llvm.org/D129170 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/deprecated-builtins.cpp Tue, 05 Jul 2022 22:37:31 +0000 Roy Jacobson <roi.jacobson1@gmail.com>
