Hello, -fno-rounding-math enables the transformation of (-(X - Y)) -> (Y - X) in simplify-rtx.c which seems to be the same transformation that enabled by -funsafe-math-optimizations in fold-const.c.
If I understand currently -frounding-math means that the rounding mode is important. In that case should there be correlation between -funsafe-math-optimizations and -fno-rounding-math (which currently does not exist)? Thanks, Revital
