[Bug tree-optimization/107254] [11/12 Regression] Wrong vectorizer code (Fortran) since r11-1501-gda2b7c7f0a136b4d
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107254 --- Comment #11 from CVS Commits --- The releases/gcc-12 branch has been updated by Richard Biener : https://gcc.gnu.org/g:fe7d74313736b8e1c30812bc49419f419bdf1c53 commit r12-8841-gfe7d74313736b8e1c30812bc49419f419bdf1c53 Author: Richard Biener 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. (cherry picked from commit 9ed4a849afb5b18b462bea311e7eee454c2c9f68)

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107254 --- Comment #10 from bartoldeman at users dot sourceforge.net --- Thanks for the fix! I can confirm that, when applied to 11.3 (with files renamed from .cc to .c), it fixes the issue, and with it, thousands of test failures in the reference LAPACK test suite. My findings for LAPACK are in this issue here: https://github.com/Reference-LAPACK/lapack/issues/732
