110 Usage of language-independent fields in a language-dependent manner:
113 This field is BINFO_INDIRECT_PRIMARY_P in a BINFO.
116 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
117 forth as a substitute for the mark bits provided in `lang_type'.
118 At present, only the six low-order bits are used.
121 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
122 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS
125 For a binfo, this is a TREE_LIST. There is an entry for each
126 virtual function declared either in BINFO or its direct and
127 indirect primary bases.
129 The BV_DELTA of each node gives the amount by which to adjust the
130 `this' pointer when calling the function. If the method is an
131 overridden version of a base class method, then it is assumed
132 that, prior to adjustment, the this pointer points to an object
135 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
136 index of the vcall offset for this entry.
138 The BV_FN is the declaration for the virtual function itself.
141 This is an expression with POINTER_TYPE that gives the value
142 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
143 to extract the VAR_DECL for the complete vtable.
146 For a VAR_DECL this is DECL_ANON_UNION_ELEMS.
149 This field is NULL for a non-virtual function. For a virtual
150 function, it is eventually set to an INTEGER_CST indicating the
151 index in the vtable at which this function can be found. When
152 a virtual function is declared, but before it is known what
153 function is overridden, this field is the error_mark_node.
155 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
156 the virtual function this one overrides, and whose TREE_CHAIN is
157 the old DECL_VINDEX. */
