Author Laurence Tratt reports successfully adapting CPython for yk (ykcpython), an automatic JIT compiler framework originally tested on smaller interpreters like PUC Lua. The adaptation took roughly 3-4 days of direct work plus a week and a half of generic bug fixing, achieving meaningful performance gains over both vanilla CPython and Python's own experimental JIT on the AWFY benchmark suite.
Background
yk is a tool that automatically adds JIT compilation capabilities to C-based interpreters, initially proven effective on PUC Lua. This follows ongoing efforts to improve Python interpreter performance through JIT techniques, competing with Python's own experimental JIT implementation.
