This is because we do not handle this in the epilogue unless there's a scalar epilogue loop. 2020-11-09 Richard Biener <rguenther@suse.de> PR tree-optimization/97760 * tree-vect-loop.c (check_reduction_path): Reject reduction paths we do not handle in epilogue generation. * gcc.dg/vect/pr97760.c: New testcase.
