> learn to write little C programs and use clang to emit the IR.

Highly recommend this. I used this to get an understanding of how to implement the IR for my language.

The command to use is `clang -S -emit-llvm -O1 foo.c`

It'll write it out to a foo.ll file.

(I use -O1 so it cleans up a bit of the messy parts of the IR).
