--- Comment #8 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:9ed4a849afb5b18b462bea311e7eee454c2c9f68 commit r13-3297-g9ed4a849afb5b18b462bea311e7eee454c2c9f68 Author: Richard Biener <rguent...@suse.de> Date: Fri Oct 14 11:14:59 2022 +0200 tree-optimization/107254 - check and support live lanes from permutes The following fixes an omission from adding SLP permute nodes which is live lanes originating from those. We have to check that we can extract the lane and have to actually code generate them. PR tree-optimization/107254 * tree-vect-slp.cc (vect_slp_analyze_node_operations_1): For permutes also analyze live lanes. (vect_schedule_slp_node): For permutes also code generate live lane extracts. * gfortran.dg/vect/pr107254.f90: New testcase.
