https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102516 --- Comment #9 from Christophe Lyon --- Indeed it works again on trunk, I bisected and it started with one of our commits: r12-3958-g4c7731081647c22cbd249dc0faa20c3df9ed6411 Author: Richard Biener Date: Wed Sep 29 11:18:23 2021 +0200 Fix peeling for alignment with negative step The following fixes a regression causing us to no longer peel negative step loops for alignment. With dr_misalignment now applying the bias for negative step we have to do the reverse when adjusting the misalignment for peeled DRs. 2021-09-29 Richard Biener * tree-vect-data-refs.c (vect_dr_misalign_for_aligned_access): New helper. (vect_update_misalignment_for_peel): Use it to update misaligned to the value necessary for an aligned access. (vect_get_peeling_costs_all_drs): Likewise. (vect_enhance_data_refs_alignment): Likewise. * gcc.target/i386/vect-alignment-peeling-1.c: New testcase. * gcc.target/i386/vect-alignment-peeling-2.c: Likewise. We still have FAIL: gcc.dg/vect/pr65947-13.c scan-tree-dump-times vect "condition expression based on integer induction." 2 but based on the original report, this was already present

Btw, with what Richard says in comment#4 I see LOOP VECTORIZED twice on recent trunk. So is this still an issue? Can somebody bisect for the fix?
