/* This tree is used to represent the expression 'object.property',
44
   where 'object' is an Objective-C object and 'property' is an
45
   Objective-C property.  Operand 0 is the object (the tree
46
   representing the expression), and Operand 1 is the property (the
47
   PROPERTY_DECL).  Operand 2 is the 'getter' call, ready to be used;
48
   we pregenerate it because it is hard to generate it properly later
49
   on.  Operand 3 records whether using the 'getter' call should
50
   generate a deprecation warning or not.
51
 
52
   A PROPERTY_REF tree needs to be transformed into 'setter' and
53
   'getter' calls at some point; at the moment this happens in two
54
   places:
55
 
56
     * if we detect that a modify expression is being applied to a
57
       PROPERTY_REF, then we transform that into a 'getter' call (this
58
       happens in build_modify_expr() or cp_build_modify_expr()).
59
 
60
    * else, it will remain as a PROPERTY_REF until we get to
61
      gimplification; at that point, we convert each PROPERTY_REF into
62
      a 'getter' call during ObjC/ObjC++ gimplify.  At that point, it
63
      is quite hard to build a 'getter' call, but we have already built
64
      it and we just need to swap Operand 2 in, and emit the deprecation
65
      warnings from Operand 3 if needed.
66
 
67
  Please note that when the Objective-C 2.0 "dot-syntax" 'object.component'
68
  is encountered, where 'component' is not a property but there are valid
69
  setter/getter methods for it, an artificial PROPERTY_DECL is generated
70
  and used in the PROPERTY_REF.  */
