107 Usage of language-independent fields in a language-dependent manner:
110 This field is BINFO_INDIRECT_PRIMARY_P in a BINFO.
113 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
114 forth as a substitute for the mark bits provided in `lang_type'.
115 At present, only the six low-order bits are used.
118 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
119 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS
122 For a binfo, this is a TREE_LIST. There is an entry for each
123 virtual function declared either in BINFO or its direct and
124 indirect primary bases.
126 The BV_DELTA of each node gives the amount by which to adjust the
127 `this' pointer when calling the function. If the method is an
128 overridden version of a base class method, then it is assumed
129 that, prior to adjustment, the this pointer points to an object
132 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
133 index of the vcall offset for this entry.
135 The BV_FN is the declaration for the virtual function itself.
138 This is an expression with POINTER_TYPE 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.
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 overridden, 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. */
