Hi GCC folks,
I have implemented a function for LANG_HOOKS_HANDLE_OPTION for my toy
language front end to handle options.
The specific option is populated in lang.opt as fdemo-debug
My lang-specs file has the following: {"@demo", "demo1 %i
%(cc1_options) %{!fsyntax-only:%(invoke_as)}", 0, 1, 0},
Everything compiles and the front end gets invoked. GCC even suggest
the correct the flag when mistyped, but my function
demo_langhook_handle_option doesn't get invoked.
What else do I need to implement to get this working.
Thanks
