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

4020 FUNCTION_DECL. The job of the thunk is to either adjust the this
4021 pointer before transferring control to the FUNCTION_DECL, or call
4022 FUNCTION_DECL and then adjust the result value. Note, the result
4023 pointer adjusting thunk must perform a call to the thunked
4024 function, (or be implemented via passing some invisible parameter
4025 to the thunked function, which is modified to perform the
4026 adjustment just before returning).

4030 o Adjust the this or result pointer by a constant offset.
4031 o Adjust the this or result pointer by looking up a vcall or vbase offset
4034 A this pointer adjusting thunk converts from a base to a derived
4035 class, and hence adds the offsets. A result pointer adjusting thunk
4036 converts from a derived class to a base, and hence subtracts the
4037 offsets. If both operations are performed, then the constant
4038 adjustment is performed first for this pointer adjustment and last

4044 into the vtable. For result pointer adjusting thunks it is the
4045 binfo of the virtual base to convert to. Use that binfo's vbase
4048 It is possible to have equivalent covariant thunks. These are
4049 distinct virtual covariant thunks whose vbase offsets happen to
