            Bug ID: 64221
           Summary: contrib/compare_tests confused by
                    c-c++-common/ubsan/shift-5.c
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: glisse at gcc dot gnu.org

Comparing a log file to itself fails. I already had to use compare_tests for
each sum file separately, since, when I enable all languages, trying to use it
on the whole tree gives:

$ /data/repos/gcc/trunk/contrib/compare_tests /tmp/testgcc/pristine
/tmp/testgcc/pristine
[...]
comm: file 2 is not in sorted order
comm: file 1 is not in sorted order
comm: file 2 is not in sorted order
New tests that FAIL:
[many many lines]
comm: file 1 is not in sorted order
Old tests that failed, that have disappeared: (Eeek!)
[the same many many lines]

But now it is getting close to useless:

$ /data/repos/gcc/trunk/contrib/compare_tests
/tmp/testgcc/pristine/build/gcc/testsuite/gcc/gcc.sum
/tmp/testgcc/pristine/build/gcc/testsuite/gcc/gcc.sum
Tests that now fail, but worked before:
