I don't see any drawback of allowing this.Differential Revision: https://reviews.llvm.org/D96832 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/attr-notail.cpp Wed, 17 Feb 2021 02:45:56 +0000 Zequan Wu <zequanwu@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/SemaCXX/attr-notail.cpp#c8667622 Add support for function attribute 'not_tail_called'.This attribute is used to prevent tail-call optimizations to the markedfunction. For example, in the following piece of code, foo1 will not betail-call optimized: int __attribute__((not_tail_called)) foo1(int);int foo2(int a) { return foo1(a); // Tail-call optimization is not performed.}The attribute has effect only on statically bound calls. It has noeffect on indirect calls. Also, virtual functions and objective-cmethods cannot be marked as 'not_tail_called'.rdar://problem/22667622Differential Revision: http://reviews.llvm.org/D12922llvm-svn: 252369 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/attr-notail.cpp Fri, 06 Nov 2015 23:56:15 +0000 Akira Hatanaka <ahatanaka@apple.com>
