Victor Stinner c6944e7edc Issue #28618: Make hot functions using __attribute__((hot)) 
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()
 2016-11-11 02:13:35 +01:00
Victor Stinner 0cae609847 Use PyThreadState_GET() in performance critical code 
It seems like _PyThreadState_UncheckedGet() is not inlined as expected, even
when using gcc -O3.

Benjamin Peterson 3924f93794 improvements to code that checks whether Python (obmalloc) allocated an address 
- Rename Py_ADDRESS_IN_RANGE to address_in_range and make it a static
  function instead of macro. Any compiler worth its salt will inline this
  function.
- Remove the duplicated function version of Py_ADDRESS_IN_RANGE used when memory
  analysis was active. Instead, we can simply mark address_in_range as allergic
  to dynamic memory checking. We can now remove the
  __attribute__((no_address_safety_analysis)) from _PyObject_Free and
  _PyObject_Realloc. All the badness is contained in address_in_range now.
- Fix the code that tried to only read pool->arenaindex once. Putting something
  in a variable is no guarantee that it won't be read multiple times. We must
  use volatile for that.

could be NULL.

It passes down the generatore to gen_close() and gen_send_ex().
gen_send_ex() did not check for gen->gi_code != NULL.

  "utf_8". So the fast path is now used for more name variants of the same
  encoding.
* Avoid strcpy() when encoding is NULL: call directly the UTF-8 codec

Victor Stinner dd69564c38 PyObject_CallMethodObjArgs() now uses fast call 
Issue #27809:

* PyObject_CallMethodObjArgs(), _PyObject_CallMethodIdObjArgs() and

  temporary tuple
* Rename objargs_mktuple() to objargs_mkstack()
* objargs_mkstack() now stores objects in a C array using borrowed references,
  instead of storing arguments into a tuple

objargs_mkstack() uses a small buffer allocated on the C stack for 5 arguments
or less, or allocates a buffer in the heap memory.

Note: this change is different than the change 0e4f26083bbb, I fixed the test
to decide if the small stack can be used or not. sizeof(PyObject**) was also
replaced with sizeof(stack[0]) since the sizeof() was wrong (but gave the same
result).
