Writing a new jit

Question

I'm interested in starting my own JIT project in C++. I'm not that unfamiliar with assembly, or compiler design etc etc. But, I am very unfamiliar with the resulting machine code format - like, what does a mov instruction actually look like when all is said and done and it's time to call that function pointer. So, what are the best resources for creating such a thing?

Edit: Right now, I'm only interested in x86 on Windows, stretching a tiny bit to 64bit Windows in the future.

Answer 1

You want to have a look at the processor manuals for the architecture you are interested in. Those manuals describe the opcode encoding. For x86 processors, the manuals can be downloaded from this page.
