            Bug ID: 82536
           Summary: gcc docs list single dash long options instead of
                    preferred double dash long options
           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: ---

The GCC documentation lists single dash option names.  For instance,
gcc/doc/invoke.texi has
@item -print-libgcc-file-name

This should be documenting --print-libgcc-file-name instead as that is the
preferred name.  This should be fixed for all options that have double dash
option names.
