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)?

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
