changeset: 106081:b9404639a18c tag: tip user: Victor Stinner <victor.stin...@gmail.com> date: Wed Jan 11 00:07:40 2017 +0100 files: Include/abstract.h Objects/abstract.c Objects/typeobject.c description: call_method() now uses _PyObject_FastCall() Issue #29233: Replace the inefficient _PyObject_VaCallFunctionObjArgs() with _PyObject_FastCall() in call_method() and call_maybe(). Only a few functions call call_method() and call it with a fixed number of arguments. Avoid the complex and expensive _PyObject_VaCallFunctionObjArgs() function, replace it with an array allocated on the stack with the exact number of argumlents. It reduces the stack consumption, bytes per call, before => after: test_python_call: 1168 => 1152 (-16 B) test_python_getitem: 1344 => 1008 (-336 B) test_python_iterator: 1568 => 1232 (-336 B) Remove the _PyObject_VaCallFunctionObjArgs() function which became useless. Rename it to object_vacall() and make it private. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29233> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
