            Bug ID: 91619
           Summary: New test case gcc.dg/vect/pr81740-2.c fails on
                    powerpc64 power7 BE
           Product: gcc
           Version: 8.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: seurer at gcc dot gnu.org
  Target Milestone: ---

I'd guess that the test case is looking for something that isn't done on
power7.  It works fine on power8 BE.
