            Bug ID: 69992
           Summary: test case gcc.dg/sms-4.c fails
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: seurer at linux dot vnet.ibm.com
  Target Milestone: ---

PASS: gcc.dg/sms-4.c (test for excess errors)
PASS: gcc.dg/sms-4.c execution test
FAIL: gcc.dg/sms-4.c scan-rtl-dump-times sms "SMS succeeded" 1

This fails on powerpc with gcc 5 and gcc 6 from trunk and it succeeds with gcc
4.9 but I am not sure if it is a regression.  I tried out several older
revisions going back over 6 months and they all fail.  It fails with both big
and little endian.  This test works on x86.
