@toshok Rpython is literally just python. They do flow analysis on the python2 bytecode and then generate static types from that. They also have magic python decorators the analyzer detects.
The Pypy tracing jit doesn't actually trace python code. It traces the rpython code too.
which is why it is called meta tracing
so it is jitting the interpreter itself which kind of blew my mind before.
/end offtopic :P

Yup, it traces an interpreter for Python. Pretty wacky, but aligns nicely with analysis/abstract interpretation

Yeah, and the GC for it is also for the language the interpreter is at.
It is really a cool design - and nice as a framework.
Does pyston use GC for all objects? or only for vm level objects.
If you get what I mean.

only for vm level objects, if I understand your question
with a few exceptions, nearly every object that the GC handles is a Python object
