  an incomplete toy barebones compiler backend for amd64 x86_64 in Python and an incomplete JIT compiler written in C (by samsquire)

I used this page to work out the Mod/RM format for opcodes.

I have a barebones toy compiler here that compiles a simple mathematical expression to assembly:

I have the beginnings of a toy JIT compiler here which generates some machine code for MOVs and function calls but I haven't implemented much else...

For code how I generate an "add" instruction:

I use a case statement to match on the registers and literally insert opcode bytes into a malloced array.
