Robin Dapp <rdapp at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Component|tree-optimization |target --- Comment #6 from Robin Dapp <rdapp at gcc dot gnu.org> --- Not the strided stores directly but rather a wrong vector length. With --param=vsetvl-strategy=simple we're good. So as Richi suspected not a vectorizer issue but the commit just exposes a latent problem.
