I agree but I think it should be stronger and we should emit a warning diagnostic that says the potential to use the specified vector library will be hampered because -fmath-errnor has been requested. I'm suggesting a warning rather than remark because we're basically saying the user has likely made a mistake because it doesn't make sense to request both features. https://github.com/llvm/llvm-project/pull/112580 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
