From 27580c1fb5e8cb756304f523006d832d2e3532e7 Mon Sep 17 00:00:00 2001 From: Victor Stinner Date: Thu, 1 Dec 2016 14:43:22 +0100 Subject: Replace PyObject_CallFunctionObjArgs() with fastcall * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507. --- Objects/enumobject.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'Objects/enumobject.c') diff --git a/Objects/enumobject.c b/Objects/enumobject.c index dae166d5ad..72d31b16af 100644 --- a/Objects/enumobject.c +++ b/Objects/enumobject.c @@ -258,7 +258,7 @@ reversed_new(PyTypeObject *type, PyObject *args, PyObject *kwds) return NULL; } if (reversed_meth != NULL) { - PyObject *res = PyObject_CallFunctionObjArgs(reversed_meth, NULL); + PyObject *res = _PyObject_CallNoArg(reversed_meth); Py_DECREF(reversed_meth); return res; } -- cgit v1.2.1
