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
