| ; To test epilogue-vectorization we need to make sure that the vectorizer actually vectorizes the loop. |
| ; Without a target triple this becomes difficult, unless we force vectorization through user hints. |
| ; Currently user provided vectorization hints prevent epilogue vectorization unless the forced |
| ; VF is the same as the epilogue vectorization VF. To make these tests target independent we'll use a |
| ; trick where both VFs are forced to be the same value. Mismatching VFs are tested in target specific tests. |
