            Bug ID: 106237
           Summary: [13 regression] serveral tests begin ICEing starting
                    with r13-1575-gcf3a120084e946
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: seurer at gcc dot gnu.org
  Target Milestone: ---

g:cf3a120084e94614a4917f71940325cd4b537f24, r13-1575-gcf3a120084e946

Related to, or maybe the same as, the later failure reported for power 7 BE in
PR106228 perhaps?  These fail in the same place but fail for power 8, 9, and 10
little endian and power 8 big endian.
