optimizing for size LV is careful to respect -Os and not to create a scalar epilog in all cases (runtime tests, trip-counts that require a remainder loop) except for peeling due to gaps in interleave-groups. This patch fixes that; -Os will now have us invalidate such interleave-groups and vectorize without an epilog. The patch also removes a related FIXME comment that is now obsolete, and was also inaccurate: "FIXME: return None if loop requiresScalarEpilog(<MaxVF>), or look for a smaller MaxVF that does not require a scalar epilog." (requiresScalarEpilog() has nothing to do with VF). Reviewers: Ayal, hsaito, dcaballe, fhahn Reviewed By: Ayal Differential Revision: https://reviews.llvm.org/D53420 llvm-svn: 344883 |
