Prior to adding `__need_unreachable` in LLVM 18, clang would never declare `unreachable()` in C++ mode, but would defer to the C++ library to do that. I think we should keep with that behavior and let libc++'s <utility> and possibly <stddef.h> headers handle declaring `unreachable()`. https://github.com/llvm/llvm-project/pull/86748 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
