* Move _PyObject_VectorcallTstate() and _PyObject_FastCallTstate() to pycore_call.h (internal C API). * Convert PyObject_CallOneArg(), PyObject_Vectorcall(), _PyObject_FastCall() and PyVectorcall_Function() static inline functions to regular functions. * Add _PyVectorcall_FunctionInline() static inline function. * PyObject_Vectorcall(), _PyObject_FastCall(), and PyObject_CallOneArg() now call _PyThreadState_GET() rather than PyThreadState_Get().

args is a C array for positional arguments.

|

nargsf is the number of positional arguments plus optionally the flag
|
|
PY_VECTORCALL_ARGUMENTS_OFFSET which means that the caller is allowed to
|
|
modify args[-1].
|
|
|
|
kwnames is a tuple of keyword names. The values of the keyword arguments
|
|
are stored in "args" after the positional arguments (note that the number
|
|
of keyword arguments does not change nargsf). kwnames can also be NULL if
|
|
there are no keyword arguments.
|
|
|
|
keywords must only contain strings and all keys must be unique.
