compiler design question

In my compiler, I have an emitter function that outputs assembly, affecting the stack, and a variable resolution function that manages local variables and their offset from ebp.

I'm trying to track types through intermediate computations, though, and i don't know whether to put this functionality in the emitter, in the scope resolution system, or to merge the two.

A touhou for your thoughts?

Are you sure Alfred V. Aho and Jeffrey D. Ullman have no Jewish genetics? Ullman especially looks like a fucking kike.
