new option --target-help to gcc (fwd)
- To: gcc-patches at gcc dot gnu dot org
- Subject: new option --target-help to gcc (fwd)
- From: Chandra Chavva <cchavva at cygnus dot com>
- Date: Wed, 22 Mar 2000 15:17:58 -0800 (PST)
Hi,
I have introduced --target-help option to the gcc which will display
target specific commands of each tool. If invoked with this option, the
gcc will pass this option to each tool and if that tool has any target
specific commands, those will get displayed to standard out.
I have added description to all mips target specific options. some of
the options descriptions were not clear, i left them as it is. Please
let me know, if my descriptions are wrong or needs to be changed.
Please let me know is it okay to apply this patch.
Thanks
Chandra
* gcc.c: New variable target_help_flag.
(display_help): Add new option and its description.
(process_command): Use it.
* toplev.c (display_target_options): New function.
(display_help): Use it.
* cccp.c (main): Use the above new option.
* config/mips/mips.h: Add description to options under
TARGET_SWITCHES and TARGET_OPTIONS.
* as.c (Options): Mention --target-help.
(parse_args): Accept --target-help.
* lexsup.c (ld_options): Mention --target-help.
(parse_args): Accept --target-help.
