[Python-checkins] CVS: python/dist/src/Include object.h,2.79.2.12,2.79.2.13

[Guido van Rossum]

Update of /cvsroot/python/python/dist/src/Include
In directory usw-pr-cvs1:/tmp/cvs-serv31479/Include

Modified Files:
      Tag: descr-branch
	object.h 
Log Message:
Change the signature of _PyObject_TypeCheck() to take two type
objects; change PyObject_TypeCheck() to hide the change from its
users.  This might generate faster code if the compiler notices that
(ob)->ob_type is loaded twice.  It also (and this was the real reason
to do this now) avoids warnings when op is not a PyObject * but a
derived object, e.g. a PyTypeObject *.
