It sounds like you want some inter-procedural analysis (IPA) info.  This 
is something that gcc does very poorly to not at all.

I suspect the only place that gcc had this info is during function inlining.

There might be some stuff on the tree-ssa branch that would be useful to 
you.  It does have some IPA.  I don't know how you would get the 
information though, as I don't work on the tree-ssa branch.

It would help if you clarified what you want.  Examples are always good.
