105 Usage of language-independent fields in a language-dependent manner:
108 This field is BINFO_INDIRECT_PRIMARY_P in a BINFO.
111 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
112 forth as a substitute for the mark bits provided in `lang_type'.
113 At present, only the six low-order bits are used.
116 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
117 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS
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. If
128 BV_USE_VCALL_INDEX_P then the corresponding vtable entry should
129 use a virtual thunk, as opposed to an ordinary thunk.
131 The BV_FN is the declaration for the virtual function itself.
134 This is an expression with POINTER_TYPE that gives the value
135 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
136 to extract the VAR_DECL for the complete vtable.
139 For a VAR_DECL this is DECL_ANON_UNION_ELEMS.
142 This field is NULL for a non-virtual function. For a virtual
143 function, it is eventually set to an INTEGER_CST indicating the
144 index in the vtable at which this function can be found. When
145 a virtual function is declared, but before it is known what
146 function is overriden, this field is the error_mark_node.
148 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
149 the virtual function this one overrides, and whose TREE_CHAIN is
150 the old DECL_VINDEX. */
