You're welcome to my code from when I went through Jack Crenshaw's
outstanding compiler tutorial. It's VC++ and comes in a compilable
project. This is "cc v2"--Crenshaw Compiler V2--and represents the
stage of the tutorial where he's got you compiling expressions and
assignments. It emits x86 assembly, but with a little tweaking is
probably exactly what you want.
