[pypy-dev] Could someone give me an idea of what is where with RPython?

[Alexander Golec]

I think it's coming together now, then. So then the code for object spaces are shared between PyPy and the RPython compiler, as is the code for abstract interpretation? The thing that triggered this was me wondering what does the interpretation of the bytecodes, but I'm guessing its the shared interpretation code?
