Writing an LLVM pass isn't too bad. Debugging one, on the other hand...

Debugging is actually not THAT bad once you get used to the debugger.

I think this is actually really old, it's been around since the early LLVM versions.

Still, it's definitely the best way to get exposed to writing optimizations using LLVM. Writing optimization passes ends up being really self-contained too (just that one file/class, and it 'automatically' gets registered into the optimizer), so it might be just one of the better ways of learning LLVM overall.
