[Bug driver/82537] New: some long options missing double dash versions


https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82537

            Bug ID: 82537
           Summary: some long options missing double dash versions
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: driver
          Assignee: unassigned at gcc dot gnu.org
          Reporter: wilson at gcc dot gnu.org
            Blocks: 82534
  Target Milestone: ---

All long options should have a double dash version, which should be the
preferred version of the option name.  This is missing for some long options.
