I'm working on the Coursera compilers class right now, which is excellent: https://class.coursera.org/compilers-004

The code generation portion of the class covers this material from the other end, i.e. at the point where the AST is transformed into assembly code, and it has been super interesting.

This is obvious in retrospect but wasn't to me beforehand: if you're interested in reverse engineering, it's very helpful to study how the assembly was written in the first place.
