Did you mean -fbroken-and-not-necessarily-fast-math? [1] [1] But really, if -ffast-math does turn -funsafe-math-optimizations on, it should have been named similarly. There is a possibility of much safer -ffast-math with almost zero breakage (by assuming a subset of IEEE 754, like the fixed rounding mode). The current -ffast-math is so reckless [2].
