I think that combining this short compiler tutorial with LLVM would be a very effective way for someone to get comfortable with basic compiler writing:
Afterward, learning how to do lexing and parsing would be a good addition. The tutorial covers a subset of scheme, which is trivially simple to parse, especially if you're writing the compiler in scheme as well.
