How do you track this inter-function and inter-module? Are you using newer interfaces exposed by GCC 4.x's GIMPLE stuff or..?
My code doesn't do any interprocedural analysis. That's why it's a thesis and not a publicly released tool :-) I used the GIMPLE representation, but at the time (around the 4.0 release) GCC did not have a stable interprocedural analysis (IPA) framework. In 4.1 there is support for IPA passes, but the SSA form of GIMPLE that I use is not available. GCC 4.2 (to be released soon) will be the first version that supports IPA on the SSA form and it will become feasible to implement my analysis as an interprocedural pass. The situation with inter-module analyses is even more complicated. The GCC developers are currently working on a project called LTO (link-time optimization), but it will probably be at least another year or two until it is usable. The good news is that if you have an interprocedural analysis pass, with LTO it should work on the whole program without any changes. If anybody is interested in implementing these kinds of analyses right now, you should probably look at LLVM.
