ba6097734d Issue #28818: Simplify lookdict functions 2016-12-07 20:41:42 +09:00

a5ed5f000a Use _PyObject_CallNoArg() 
Replace:
    PyObject_CallObject(callable, NULL)
with:
    _PyObject_CallNoArg(callable)

de4ae3d486 Backed out changeset b9c9691c72c5 
Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like
_PyObject_CallArg1() uses more stack memory than
PyObject_CallFunctionObjArgs().
 2016-12-04 22:59:09 +01:00
Victor Stinner
27580c1fb5 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.

0cae609847 Use PyThreadState_GET() in performance critical code 
It seems like _PyThreadState_UncheckedGet() is not inlined as expected, even
when using gcc -O3.

after any change.

By default, tables are not checked, only basic attributes. Define DEBUG_PYDICT
