--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Dmitrij Pochepko from comment #6) > Just checked: non-vectorized assembly for aarch64 (O2) is using fmadd and > fmsub intensively. Try with -ffp-contract=off then. Note due to effective unrolling of the loop with vectorization we might end up forming "different" fmadd groups. So you might also want to check whether the vectorized loop still sees fmadd use.
