| | | | | Sorry, I didn't want to push this change before the review :-( I was pushing a change into the 2.7 branch.
* Issue #29465: Add Objects/call.c fileVictor Stinner2017-02-101-239/+3

| | | | Replace the runtime check with an assertion (just in case).
* 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)
* Optimize _PyFunction_FastCallDict() when kwargs is {}Victor Stinner2017-01-031-3/+5
| | | | | Issue #28839: Optimize _PyFunction_FastCallDict() when kwargs is an empty dictionary, avoid the creation of an useless empty tuple.

* Issue #26110: Add LOAD_METHOD/CALL_METHOD opcodes.Yury Selivanov2016-12-141-0/+97
| | | | | | | Special thanks to INADA Naoki for pushing the patch through the last mile, Serhiy Storchaka for reviewing the code, and to Victor Stinner for suggesting the idea (originally implemented in the PyPy project).
* Backed out changeset 99c34e47348bVictor Stinner2016-12-091-2/+2
| | | | The change broke test_gdb.
* Inline PyEval_EvalFrameEx() in callersVictor Stinner2016-12-091-2/+2
| | | | | | | | The PEP 523 modified PyEval_EvalFrameEx(): it's now an indirection to interp->eval_frame(). Inline the call in performance critical code. Leave PyEval_EvalFrame() unchanged, this function is only kept for backward compatibility.
* Use _PyObject_CallNoArg()Victor Stinner2016-12-061-2/+2
| | | | | | | Replace: PyObject_CallFunctionObjArgs(callable, NULL) with: _PyObject_CallNoArg(callable)
* Use _PyObject_CallNoArg()Victor Stinner2016-12-061-2/+2
| | | | | | | Replace: PyObject_CallObject(callable, NULL) with: _PyObject_CallNoArg(callable)
* Uniformize argument names of "call" functionsVictor Stinner2016-12-061-3/+4
| | | | | | | | | | | | Issue #28838: Rename parameters of the "calls" functions of the Python C API. * Rename 'callable_object' and 'func' to 'callable': any Python callable object is accepted, not only Python functions * Rename 'method' and 'nameid' to 'name' (method name) * Rename 'o' to 'obj' * Move, fix and update documentation of PyObject_CallXXX() functions in abstract.h * Update also the documentaton of the C API (update parameter names)
* Backed out changeset b9c9691c72c5Victor Stinner2016-12-041-3/+3
| | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().
* WITH_CLEANUP_START uses fastcallVictor Stinner2016-12-011-3/+10
| | | | | Modify WITH_CLEANUP_START bytecode: replace PyObject_CallFunctionObjArgs() with _PyObject_FastCall().
* Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-011-3/+3
| | | | | | | | | | | | | | * 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.

* | Issue #28618: Make hot functions using __attribute__((hot))Victor Stinner2016-11-111-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When Python is not compiled with PGO, the performance of Python on call_simple and call_method microbenchmarks depend highly on the code placement. In the worst case, the performance slowdown can be up to 70%. The GCC __attribute__((hot)) attribute helps to keep hot code close to reduce the risk of such major slowdown. This attribute is ignored when Python is compiled with PGO. The following functions are considered as hot according to statistics collected by perf record/perf report: * _PyEval_EvalFrameDefault() * call_function() * _PyFunction_FastCall() * PyFrame_New() * frame_dealloc() * PyErr_Occurred()
