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. The BV_DELTA of each node
126 gives the amount by which to adjust the `this' pointer when
127 calling the function. If the method is an overriden version of a
128 base class method, then it is assumed that, prior to adjustment,
129 the this pointer points to an object of the base class.
131 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
132 index of the vcall offset for this entry. If
133 BV_USE_VCALL_INDEX_P then the corresponding vtable entry should
134 use a virtual thunk, as opposed to an ordinary thunk.
136 The BV_FN is the declaration for the virtual function itself.
139 This is an expression with POINTER_TYPE 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.
144 For a VAR_DECL this is DECL_ANON_UNION_ELEMS.
147 This field is NULL for a non-virtual function. For a virtual
148 function, it is eventually set to an INTEGER_CST indicating the
149 index in the vtable at which this function can be found. When
150 a virtual function is declared, but before it is known what
151 function is overriden, this field is the error_mark_node.
153 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
154 the virtual function this one overrides, and whose TREE_CHAIN is
155 the old DECL_VINDEX. */
