            Bug ID: 88708
           Summary: help-dummy.o file left behind
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: driver
          Assignee: unassigned at gcc dot gnu.org
          Reporter: drepper.fsp+rhbz at gmail dot com
  Target Milestone: ---

When using

  gcc -c -Q -O --help=optimizers

the driver leaves behind the help-dummy.o file.  This happens with gcc trunk
and all prior versions I was able to test.
