104 Usage of language-independent fields in a language-dependent manner:
107 This field is BINFO_INDIRECT_PRIMARY_P in a BINFO.
110 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
111 forth as a substitute for the mark bits provided in `lang_type'.
112 At present, only the six low-order bits are used.
115 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
116 For a TYPENAME_TYPE, this is TYPENAME_TYPE_FULLNAME.
117 For a TEMPLATE_TEMPLATE_PARM or BOUND_TEMPLATE_TEMPLATE_PARM,
118 this is TEMPLATE_TEMPLATE_PARM_TEMPLATE_INFO.
121 For a binfo, this is a TREE_LIST. The BV_DELTA of each node
122 gives the amount by which to adjust the `this' pointer when
123 calling the function. If the method is an overriden version of a
124 base class method, then it is assumed that, prior to adjustment,
125 the this pointer points to an object of the base class.
127 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
128 index of the vcall offset for this entry. If
129 BV_USE_VCALL_INDEX_P then the corresponding vtable entry should
130 use a virtual thunk, as opposed to an ordinary thunk.
132 The BV_FN is the declaration for the virtual function itself.
133 When CLASSTYPE_COM_INTERFACE_P does not hold, the first entry
134 does not have a BV_FN; it is just an offset.
136 The BV_OVERRIDING_BASE is the binfo for the final overrider for
137 this function. (This binfo's BINFO_TYPE will always be the same
138 as the DECL_CLASS_CONTEXT for the function.)
141 Sometimes this is a VAR_DECL. Under the new ABI, it is instead
142 an expression with POINTER_TYPE pointing that gives the value
143 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
144 to extract the VAR_DECL for the complete vtable; that macro works
148 For a VAR_DECL this is DECL_ANON_UNION_ELEMS.
151 This field is NULL for a non-virtual function. For a virtual
152 function, it is eventually set to an INTEGER_CST indicating the
153 index in the vtable at which this function can be found. When
154 a virtual function is declared, but before it is known what
155 function is overriden, this field is the error_mark_node.
157 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
158 the virtual function this one overrides, and whose TREE_CHAIN is
159 the old DECL_VINDEX. */
