Hi, I may not have correctly understood your questions but from what I understand I think you mean to ask how you could easily plug in your optimization pass into GCC so as to test your implementation of some optimization.
Well, the way to do that would be to understand the pass structure and decide where in the order of passes should your pass be inserted i.e after which and before which other pass should your optimization pass fit in. Look at passes.c to see how the order of passes is specified. Once you have told the compiler when to execute your pass (primarily through passes.c) and provided your optimization has been correctly implemented in the context of GCC you should be good to go.
