But unfortunately with the patch it still fails when testing for -mcpu=power7 on ppc64le-linux-gnu: it does vectorize the loop with 13 iterations. We need 16 iterations, as in an earlier version of this test, for it to pass for -mcpu=power7, but then it doesn't pass for -mcpu=power6. It looks like we're going to have to adjust the expectations. -- Alexandre Oliva, happy hacker https://FSFLA.org/blogs/lxo/ Free Software Activist GNU Toolchain Engineer More tolerance and less prejudice are key for inclusion and diversity Excluding neuro-others for not behaving ""normal"" is *not* inclusive
