commit e8ba59ef5c6284604f3c0920e246ed4cf889e541 Author: Richard Biener <rguent...@suse.de> Date: Thu Oct 5 13:31:16 2023 +0200 Reduce single-lane SLP testresult noise The following avoids dumping 'vectorizing stmts using SLP' for single-lane instances since that causes extra testsuite fallout. * tree-vect-slp.cc (vect_schedule_slp): Gate dumping 'vectorizing stmts using SLP' on > 1 lanes.
