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 TYPENAME_TYPE, this is TYPENAME_TYPE_FULLNAME.
118 For a TEMPLATE_TEMPLATE_PARM or BOUND_TEMPLATE_TEMPLATE_PARM,
119 this is TEMPLATE_TEMPLATE_PARM_TEMPLATE_INFO.
122 For a binfo, this is a TREE_LIST. The BV_DELTA of each node
123 gives the amount by which to adjust the `this' pointer when
124 calling the function. If the method is an overriden version of a
125 base class method, then it is assumed that, prior to adjustment,
126 the this pointer points to an object of the base class.
128 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
129 index of the vcall offset for this entry. If
130 BV_USE_VCALL_INDEX_P then the corresponding vtable entry should
131 use a virtual thunk, as opposed to an ordinary thunk.
133 The BV_FN is the declaration for the virtual function itself.
136 This is an expression with POINTER_TYPE that gives the value
137 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
138 to extract the VAR_DECL for the complete vtable.
141 For a VAR_DECL this is DECL_ANON_UNION_ELEMS.
144 This field is NULL for a non-virtual function. For a virtual
145 function, it is eventually set to an INTEGER_CST indicating the
146 index in the vtable at which this function can be found. When
147 a virtual function is declared, but before it is known what
148 function is overriden, this field is the error_mark_node.
150 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
151 the virtual function this one overrides, and whose TREE_CHAIN is
152 the old DECL_VINDEX. */
