I expected -fno-unsafe-math-optimizations would be the default behavior and only undo -funsafe-math-optimizations. Instead it enables constrained intrinsics. https://godbolt.org/z/ooYdY4Kox
I checked with @andykaylor who thought this behavior might be because gcc documentation says -fno-unsafe-math-optimizations implies -ftrapping-math. gcc has -ftrapping-math by default, but clang does not.
