            Bug ID: 65191
           Summary: keep interesting core files and remove others
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org

If you run into a test failure, and it's hard to reproduce, you're interested
in the core file for the original failure.

If the target machine is set to generate cores with the simple name 'core', the
core you're interested in may already have been overwritten, f.i. by a
non-interesting xfail abort.

It might be a good idea to distinguish between interesting and non-interesting
cores, and keep the interesting ones.
