Object code lecture notes

Here are my lecture slides on LLVM IR code generation (up to data flow analysis, which I posted yesterday).  Some of these have been posted before, but I think the first of those below, on walking the AST to generate LLVM IR, has not.

• From AST to IR  (expressions, control flow, short-circuit conditions)
• Addressing in LLVM, Where things live and More on LLVM addressing of objects 

I think that's it, but if you're missing something you recall from lecture, please let me know.
