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