Byte code descriptions somewhere?

[Cem Karan]

Hi all, I've all of a sudden gotten interested in the CPython interpreter, and started trying to understand how it ingests and runs byte code.  I found Include/opcode.h in the python sources, and I found some basic documentation on how to add in new opcodes online, but I haven't found the equivalent of an assembly manual like you might for x86, etc.  Is there something similar to a manual dedicated to python byte code?  Also, is there a manual for how the interpreter expects the stack, etc. to be setup so that all interactions go as expected (garbage collections works, exceptions work, etc.)?  Basically, I want a manual similar to what Intel or AMD might put out for their chips so that all executables behave nicely with one another.

Thanks,
