A similar issue exists when peeling for gaps. 2022-04-27 Richard Biener <rguent...@suse.de> PR tree-optimization/105219 * tree-vect-loop.cc (vect_transform_loop): Disable special code narrowing the vectorized epilogue max iterations when peeling for alignment or gaps was in effect. * gcc.dg/vect/pr105219.c: New testcase.
