I'm not sure whether you mean it, but I'd expect that it's handled like `signbit` and friends - they are functions instead of macros. For libc++ that would simply be `#undef unreachable`, `#include <__utility/unreachable.h>` and `using std::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
