            Bug ID: 103998
           Summary: [12 Regression] Recent vectorizer testsuite
                    regressions on x86
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jakub at gcc dot gnu.org
  Target Milestone: ---

I'm seeing on x86_64-linux:

   && [ -f testsuite/gcc-parallel/finished ]; then \
  rm -rf testsuite/gcc; \

None of this was present when I bootstrapped/regtested 24 hours ago with
r12-6420 reverted.
If I revert r12-6523 and r12-6420 on current trunk, then all these pass again.
