I have been trying to examine the i386 code generator to see how feasible it would be to create an AMD64 code generator. Unfortunately, the code is uncommented, and I haven't yet found any documentation to explain how it works on Parrot. So far I've determined there's relevant stuff in jit/i386. I don't understand the .jit extension on core.jit. Is that not actually heavily templated C code?
I'm curious if there's other sources to study. Preferably, I'd like to get some advice on how to study this code generator so I can at least improve it. I'd prefer to become knowledgeable enough to add an AMD64 generator sometime. However, I'll gladly advise only if somebody has already started it.
