* Issue #29465: Add Objects/call.c fileVictor Stinner2017-02-101-6/+16
| | | | | | | | | | * Move all functions to call objects in a new Objects/call.c file. * Rename fast_function() to _PyFunction_FastCallKeywords(). * Copy null_error() from Objects/abstract.c * Inline type_error() in call.c to not have to copy it, it was only called once. * Export _PyEval_EvalCodeWithName() since it is now called from call.c.
* Optimize slots: avoid temporary PyMethodObjectVictor Stinner2017-02-091-0/+6
| | | | | | | | | | | | | | | | | | Issue #29507: Optimize slots calling Python methods. For Python methods, get the unbound Python function and prepend arguments with self, rather than calling the descriptor which creates a temporary PyMethodObject. Add a new _PyObject_FastCall_Prepend() function used to call the unbound Python method with self. It avoids the creation of a temporary tuple to pass positional arguments. Avoiding temporary PyMethodObject and avoiding temporary tuple makes Python slots up to 1.46x faster. Microbenchmark on a __getitem__() method implemented in Python: Median +- std dev: 121 ns +- 5 ns -> 82.8 ns +- 1.0 ns: 1.46x faster (-31%) Co-Authored-by: INADA Naoki <songofacandy@gmail.com>

| | | | | | | | | | | | | | | | | | | | | It got messed up when I merged my private 3.5.3 release changes with new work happening in the 3.5 main branch. (3.5 main branch was in "3.5.3rc1", my branch was "3.5.3+", and Mercurial helpfully merged the two in a kind of nonsense way.)

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.
