I think we should just use the GNU-compatible ABI by default. Unless there's some existing OS where clang is the platform compiler that wants to preserve the old ABI, but even if such a platform exists, I doubt there's anyone we can ask. https://github.com/llvm/llvm-project/pull/77732 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
