This is also a bit of a problem. After inlining we can have instructions with fast-math disabled appearing in the middle of functions that were compiled with fast-math enabled. What happens to the "denormal-fp-math" attribute in such cases? I wanted to show this in compiler explorer, but "#pragma float_control()" doesn't update the "denormal-fp-math attribute. https://godbolt.org/z/KEP3YEEe9 I may have mentioned a few times that I don't like function attributes controlling fast-math behaviors. https://github.com/llvm/llvm-project/pull/80475 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
