In particular detection works starting from non-SLP stmts following use->def chains rather than walking the SLP graph and following def->use chains. This picks a rewrite from GCC 11 for the old code didn't handle pattern sequences correctly. 2020-05-05 Richard Biener <rguent...@suse.de> PR tree-optimization/96513 * tree-vect-slp.c (struct vdhs_data): New.
