compiler construction - How to capture command line options when writting gcc plugin -


i adding new features on cpp, want write compiler pass modify cpp source codes according different options.(i use gcc feature(cilk) , think cannot done libclang,clang cannot recognize cilk). there api in gcc can such things?

the current gcc plugin api not allow extend preprocessor. however, can add builtins, pragmas, , function or variable attributes.

you use save_decoded_options , save_decoded_options_count toplev.h compiler program arguments. plugins expecting -fplugin-foo-arg- program arguments (for plugin foo ...)

why need these?

did consider extending gcc melt (a domain specific language extend gcc)?
