Ah, right. Yes, the stuff you see at the GIMPLE level has already been
substantially processed compared to the original AST - operations decomposed,
constants folded, that kind of thing. For instance if (like Andrew suggests)
we add a "int x;" declaration in class A from your original example, we get:

You probably need to look earlier than GIMPLE time. What plugin event are
you hooking?
