* Disable _PyStack_AsTuple() inliningVictor Stinner2017-01-112-2/+17
| | | | | | | | | | | | | | | 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)
* Inline call_function()Victor Stinner2017-01-101-2/+4
| | | | | | | | | | | | | Issue #29227: Inline call_function() into _PyEval_EvalFrameDefault() using Py_LOCAL_INLINE to reduce the stack consumption. It reduces the stack consumption, bytes per call, before => after: test_python_call: 1152 => 1040 (-112 B) test_python_getitem: 1008 => 976 (-32 B) test_python_iterator: 1232 => 1120 (-112 B) => total: 3392 => 3136 (- 256 B)
* call_method() now uses _PyObject_FastCall()Victor Stinner2017-01-103-52/+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.

| | * Issue #29157: Prefer getrandom() over getentropy()Victor Stinner2017-01-091-200/+294
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Copy and then adapt Python/random.c from default branch. Difference between 3.5 and default branches: * Python 3.5 only uses getrandom() in non-blocking mode: flags=GRND_NONBLOCK * If getrandom() fails with EAGAIN: py_getrandom() immediately fails and remembers that getrandom() doesn't work. * Python 3.5 has no _PyOS_URandomNonblock() function: _PyOS_URandom() works in non-blocking mode on Python 3.5
