From 7a5b674721161bdc60d375cde69b9372539f9191 Mon Sep 17 00:00:00 2001 From: Thomas Wouters Date: Wed, 27 Jun 2001 13:09:44 +0000 Subject: Backport Jeremy's checkin 2.244: Add a second special case to the inline function call code in eval_code2(). If we have a PyCFunction (builtin) and it is METH_VARARGS only, load the args and dispatch to call_cfunction() directly. This provides a small speedup for perhaps the most common function calls -- builtins. --- Python/ceval.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/Python/ceval.c b/Python/ceval.c index b6686b6..64dbf98 100644 --- a/Python/ceval.c +++ b/Python/ceval.c @@ -1941,7 +1941,13 @@ eval_code2(PyCodeObject *co, PyObject *globals, PyObject *locals, callable object. */ if (PyCFunction_Check(func)) { - if (PyCFunction_GET_FLAGS(func) == 0) { + int flags = PyCFunction_GET_FLAGS(func); + if (flags == METH_VARARGS) { + PyObject *callargs; + callargs = load_args(&stack_pointer, na); + x = call_cfunction(func, callargs, NULL); + Py_XDECREF(callargs); + } else if (flags == 0) { x = fast_cfunction(func, &stack_pointer, na); } else { -- cgit v0.12
