@kmod I will try to address the division overflow issues. And I update the Pyston weekly status notes. Would you mind to give some suggestions, please?

I don't know
but I think it stems from how we try get the rounding right
I would just look at how cpython does it and try to copy it

looks like we do the adjustment pre-division
but cpython does the adjustment post-division
which looks safer

I try to run 'pyston -Snvv test.py' and break at pyston::emitBBs by GDB. I found that every time when the program break at my break-point. entry_descriptor==NULL
Is it OK?

I think this is fine this is only set when we do OSR (eg it will get set if we encounter a hot loop and just recompile the loop but not if we compile the whole func)

no not really
it sounds like there's quite a bit that's different, especially internally
