--- Comment #19 from Richard Biener <rguenth at gcc dot gnu.org> --- On Zen I measure 23s with --param vect-max-version-for-alias-checks=0 (thus basically before the rev.) and 33s without. With the patch and the size parameter tuned to 146 I get 25s and with 90 it is 22.5s. So Zen seems to be a bit pickier (code-size wise) than Broadwell.
