            Bug ID: 65021
           Summary: nvptx mkoffload doesn't clean up its temporary files
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Keywords: openacc, openmp
          Severity: major
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tschwinge at gcc dot gnu.org
                CC: bernds at gcc dot gnu.org

The nvptx mkoffload doesn't clean up its temporary files, so ${TMPDIR-/tmp}/
slowly fills up with cc* files, "until it explodes".

Related to that, do we generally need to add atexit as well as signal handlers?
