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