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