Ooof... I know @AaronBallman suggested reusing the diagnostic... can we do at least a note (perhaps pointing to the attribute `not_tail_called`) to show WHY we are emitting this error? Something like: `note: 'not_tail_called' attribute here prevents being called as a tail call'? https://github.com/llvm/llvm-project/pull/134465 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
