Yes. Any scenario where `MathErrno` ends up being true after `-fveclib=ArmPL` has cleared it should generate the warning. I'm expecting this to keeps things simple because it can be checked once as part of the code that then adds the `-fmath-errno` option. 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
