Musings on Tracing in PyPy

The equivalent of this (and strongly inspired by luajit's ffi) in the python world is cffi, btw: https://cffi.readthedocs.io/en/stable/

Oh, thanks! That's a second thing in this thread I'm embarrassed to have not known already. Does it get native-like performance in PyPy the way LuaJIT's FFI does? I'll have to try it with Yeso to see if it's an improvement.

It should get pretty good performance yes. Not sure how native like we get with the jit. Gut feeling would be a bit slower than gcc -O0? I would be very interested in your experience if you do try it.

Thanks! I guess now I've assumed the obligation. Probably I should look for you on Mastodon in order to tell you about my experience?
