            Bug ID: 60173
           Summary: [4.9 Regression]: gcc.dg/binop-xor1.c
                    scan-tree-dump-times
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: regression
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hp at gcc dot gnu.org

This test previously passed, now it fails.
A patch in the revision range (last_known_working:first_known_failing)
207658:207668 exposed or caused this regression.  Since then it fails as
follows:

Running /tmp/hpautotest-gcc1/gcc/gcc/testsuite/gcc.dg/dg.exp ...
FAIL: gcc.dg/binop-xor1.c scan-tree-dump-times optimized "\\^" 1

This test also fails for at least the following targets (revision, link to
gcc-testresults@)
powerpc64-unknown-linux-gnu (207741
<http://gcc.gnu.org/ml/gcc-testresults/2014-02/msg00830.html>),
m68k-unknown-linux-gnu (unknown,
<http://gcc.gnu.org/ml/gcc-testresults/2014-02/msg00849.html>),
s390x-ibm-linux-gnu (207735,
<http://gcc.gnu.org/ml/gcc-testresults/2014-02/msg00828.html>),
powerpc-ibm-aix7.1.0.0 (207693,
<http://gcc.gnu.org/ml/gcc-testresults/2014-02/msg00752.html>), 

(The failure is not universal, it seems to not fail for at least as many other
targets.)
