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

3649 FUNCTION_DECL. The job of the thunk is to either adjust the this
3650 pointer before transferring control to the FUNCTION_DECL, or call

3652 pointer adjusting thunk must perform a call to the thunked
3653 function, (or be implemented via passing some invisible parameter
3654 to the thunked function, which is modified to perform the

3659 o Adjust the this or result pointer by a constant offset.
3660 o Adjust the this or result pointer by looking up a vcall or vbase offset
3663 A this pointer adjusting thunk converts from a base to a derived
3664 class, and hence adds the offsets. A result pointer adjusting thunk
3665 converts from a derived class to a base, and hence subtracts the
3666 offsets. If both operations are performed, then the constant
3667 adjustment is performed first for this pointer adjustment and last
3668 for the result pointer adjustment.

3671 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
3672 used. For this pointer adjusting thunks, it is the vcall offset
3673 into the vtable. For result pointer adjusting thunks it is the
3674 binfo of the virtual base to convert to. Use that binfo's vbase
3677 It is possible to have equivalent covariant thunks. These are
3678 distinct virtual covariant thunks whose vbase offsets happen to
