Hi all, I'm using a gcc plugin to do some instrument during compilation.
Instrument in functions is simple. But how can I create new functions, and append it to executables? I want to instrument in this way: to create new functions, add my codes into them, then instrument some calls to them. foo: call to new_function; //instrument a call new_function: //created function instrument codes here I think the most difficult part is to create functions. If it's possible to do so, can I create functions at any phase during compilation(with a gimple, or a rtl pass)? Any tips?
