--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Why do you think it is wrong? As documented, -ffp-contract= defaults to
-ffp-contract=fast, which allows contraction and so on x * y + z etc. fma can
be used instead. For most of code, it doesn't make a significant difference,
but of course there are various cases where it makes a significant difference.
If some code relies on contraction not happening, you should use
-ffp-contract=off.
