Message 285405 - Python tracker (original) (raw)

Ok, here is a first patch: tp_fastcall.patch

• Add tp_fastcall to PyTypeObject

• Add fastcall_wrapper() and use it for tp_call in PyType_Ready()

• Modify _PyObject_FastCallDict() and _PyObject_FastCallKeywords() to use tp_fastcall if defined

• Modify a lot of types to define tp_fastcall instead of tp_call (to use FASTCALL calling convention)

• Add a few new helper functions:

  • _PyObject_FastCall_Prepend() -- similar to _PyObject_Call_Prepend()
  • _Py_FastCall_FromArgs() -- ugly name, sorry about that, it should be renamed :-)
  • PyArg_UnpackStack() -- similar to PyArg_UnpackTuple()
  • _PyArg_NoStackKeywords() -- similar to _PyArg_NoKeywords

Hum, I should make sure that these new functions are not public. By the way, I should probably rename PyArg_UnpackStack() to _PyArg_UnpackStack().
