* Run Argument Clinic: METH_VARARGS=>METH_FASTCALLVictor Stinner2017-01-173-39/+87
| | | | | Issue #29286. Run Argument Clinic to get the new faster METH_FASTCALL calling convention for functions using only positional arguments.
* _PyStack_UnpackDict() now returns -1 on errorVictor Stinner2017-01-172-9/+11
| | | | | Issue #29286. Change _PyStack_UnpackDict() prototype to be able to notify of failure when args is NULL.
* Rename _PyArg_ParseStack to _PyArg_ParseStackAndKeywordsVictor Stinner2017-01-174-16/+16
| | | | Issue #29286.

* Optimize _PyCFunction_FastCallKeywords()Victor Stinner2017-01-161-36/+131
| | | | | | | | | | | | | | Issue #29259: Write fast path in _PyCFunction_FastCallKeywords() for METH_FASTCALL, avoid the creation of a temporary dictionary for keyword arguments. Cleanup also _PyCFunction_FastCallDict(): * Don't dereference func before checking that it's not NULL * Move code to raise the "no keyword argument" exception into a new no_keyword_error label. Update python-gdb.py for the change.

* | | Disable _PyStack_AsTuple() inliningVictor Stinner2017-01-111-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #29234: Inlining _PyStack_AsTuple() into callers increases their stack consumption, Disable inlining to optimize the stack consumption. Add _Py_NO_INLINE: use __attribute__((noinline)) of GCC and Clang. It reduces the stack consumption, bytes per call, before => after: test_python_call: 1040 => 976 (-64 B) test_python_getitem: 976 => 912 (-64 B) test_python_iterator: 1120 => 1056 (-64 B) => total: 3136 => 2944 (- 192 B)
* | | call_method() now uses _PyObject_FastCall()Victor Stinner2017-01-102-44/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | function_call() now simply calls _PyFunction_FastCallDict(). _PyFunction_FastCallDict() is more efficient: it contains fast paths for the common case (optimized code object and no keyword argument).
