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