Okay, that seems justifiable. >>> In `clang/test/CodeGen/complex-math.c` I've added `-ffp-contract=fast` to >>> the command line option because `-ffast-math` at the CC1 level does not >>> change the default contraction mode. >> >> Oh, I see, makes sense.

I'm actually surprised it doesn't. I can't imagine why someone enabling fast math would want contraction to be disabled.
