            Bug ID: 65138
           Summary: [5 Regression] testsuite ICEs on powerpc64le
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: trippels at gcc dot gnu.org
              Host: powerpc64le-unknown-linux-gnu
            Target: powerpc64le-unknown-linux-gnu
             Build: powerpc64le-unknown-linux-gnu

Running the testsuite on the new gcc2-2-power8.osuosl.org powerpc64le machine
shows:

These all have the same backtrace:
