--- Comment #4 from Marc Glisse <glisse at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #3) > Perhaps we want to perform it just during ifcvt once it is rolled into > vectorizer and works on an on-the-side bb? Then it wouldn't affect > non-vectorized code. We would miss some useful cases (in the original testcase, the transformation is worth it even without vectorizing), but at least it would make regressions unlikely...
