           Summary: Driver --help should use common help code
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: driver
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jsm28@gcc.gnu.org


At present gcc.c has its own code to handle --help and producing help text for
driver options and the code in opts.c excludes driver options.  This should be
changed so that driver options have help text in the .opt files and this text
is used by the common machinery in producing --help output.  (I don't know what
division between the driver and cc1 in producing that output would then be
appropriate.)
