New submission from Jeroen Demeyer <j.deme...@ugent.be>:
The PEP 590 implementation for type "method" caused a minor regression: instead of using _PyObject_Call_Prepend(), method_vectorcall manually allocates and fills a newly allocated vector. This does NOT use the _PY_FASTCALL_SMALL_STACK optimization, but it should. ---------- components: Interpreter Core messages: 345234 nosy: jdemeyer priority: normal severity: normal status: open title: Use _PY_FASTCALL_SMALL_STACK for method_vectorcall type: performance versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37233> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
