There's no mapping Id -> CmmProc in the CgMonad at the moment, but it'd be easy to add, at least for top-level procedures.
However in the example you give, 'f' is a parameter of 'map', so there's no hope of finding what it's bound to, because that depends on the caller (which might not even have been written yet). Furthermore, 'f' is a closure (a pair of code and environment) not just code.

I have looked at the information passed using CgMonad and at the bindings in scope but these don't seem to be what I need. As an example, when generating code for the tail call "map f xs," can I retrieve the Cmm expressions that make up "f"? Apologies if I am missing something glaringly obvious, thanks, Will
