STINNER Victor <vstin...@python.org> added the comment:
When I designed the FASTCALL calling convention, I experimented a new tp_fastcall slot to PyTypeObject to optimize __call__() method: bpo-29259. Results on the pyperformance benchmark suite were not really convincing and I had technical issues (decide if tp_call or tp_fastcall should be called, handle ABI compatibility and backward compatibility, etc.). I decided to give up on this idea. I'm happy to see that PEP 590 managed to find its way into Python internals and actually make Python faster ;-) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37207> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
