105 Usage of language-independent fields in a language-dependent manner:
108 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
109 forth as a substitute for the mark bits provided in `lang_type'.
110 At present, only the six low-order bits are used.
113 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
114 For a TYPENAME_TYPE, this is TYPENAME_TYPE_FULLNAME.
115 For a TEMPLATE_TEMPLATE_PARM, this is
116 TEMPLATE_TEMPLATE_PARM_TEMPLATE_INFO.
119 For a binfo, this is a TREE_LIST. The BV_DELTA of each node
120 gives the amount by which to adjust the `this' pointer when
121 calling the function. If the method is an overriden version of a
122 base class method, then it is assumed that, prior to adjustment,
123 the this pointer points to an object of the base class.
125 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
126 index of the vcall offset for this entry.
128 The BV_FN is the declaration for the virtual function itself.
129 When CLASSTYPE_COM_INTERFACE_P does not hold, the first entry
130 does not have a BV_FN; it is just an offset.
132 The BV_OVERRIDING_BASE is the binfo for the final overrider for
133 this function. (This binfo's BINFO_TYPE will always be the same
134 as the DECL_CLASS_CONTEXT for the function.)
137 Sometimes this is a VAR_DECL. Under the new ABI, it is instead
138 an expression with POINTER_TYPE pointing that gives the value
139 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
140 to extract the VAR_DECL for the complete vtable; that macro works
144 For a VAR_DECL this is DECL_ANON_UNION_ELEMS.
147 This field is NULL for a non-virtual function. For a virtual
148 function, it is eventually set to an INTEGER_CST indicating the
149 index in the vtable at which this function can be found. When
150 a virtual function is declared, but before it is known what
151 function is overriden, this field is the error_mark_node.
153 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
154 the virtual function this one overrides, and whose TREE_CHAIN is
155 the old DECL_VINDEX. */
