--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> --- On the trunk, I see no loop at all for the original testcase at -O3. At -O2 -ftree-vectorize, I do see the loop but when I add -funroll-loops, the loop is completely unrolled at the gimple level. So maybe the vectorizer is much better now really.
