Hello everyone: I want use gcc's "-finstrument-functions" option to hack a open-source project. But if i want to make the most use of this option, i should tell the compiler the my own definition of "__cyg_profile_func_enter" and "__cyg_profile_func_exit" functions. If the project i want to hack will create many different 'elf' files,and different 'elf' use different source files,so i have to define the two function in many many files. Is there some easy ways to tell the compiler my function's definition???
