Per discussion in https://github.com/llvm/llvm-project/issues/83616, I did not tie the fix to the `-fclang-abi-compat=` option. I checked for uses of `LangOptions::ClangABI` and while I see many such uses in `ItaniumMangle.cpp`, there are currently none in `MicrosoftMangle.cpp`. https://github.com/llvm/llvm-project/pull/85300 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
