144 Usage of language-independent fields in a language-dependent manner:
147 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
148 forth as a substitute for the mark bits provided in `lang_type'.
149 At present, only the six low-order bits are used.
152 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
153 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS
156 For a binfo, this is a TREE_LIST. There is an entry for each
157 virtual function declared either in BINFO or its direct and
158 indirect primary bases.
160 The BV_DELTA of each node gives the amount by which to adjust the
161 `this' pointer when calling the function. If the method is an
162 overridden version of a base class method, then it is assumed
163 that, prior to adjustment, the this pointer points to an object
166 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
167 index of the vcall offset for this entry.
169 The BV_FN is the declaration for the virtual function itself.
171 If BV_LOST_PRIMARY is set, it means that this entry is for a lost
172 primary virtual base and can be left null in the vtable.
175 This is an expression with POINTER_TYPE that gives the value
176 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
177 to extract the VAR_DECL for the complete vtable.
180 This field is NULL for a non-virtual function. For a virtual
181 function, it is eventually set to an INTEGER_CST indicating the
182 index in the vtable at which this function can be found. When
183 a virtual function is declared, but before it is known what
184 function is overridden, this field is the error_mark_node.
186 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
187 the virtual function this one overrides, and whose TREE_CHAIN is
188 the old DECL_VINDEX. */
