Hm, alive2 doesn't support fast-math flags still?
Filed https://github.com/AliveToolkit/alive2/issues/667
This seems fine to me.
================
Comment at: llvm/test/Transforms/InstCombine/fdiv.ll:698
%p = call fast float @llvm.pow.f32(float %x, float %y)
%r = fdiv reassoc float %z, %p
ret float %r
----------------
Might be worth duplicating the test with `reassoc` missing instead?
