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

3683 pointer before transferring control to the FUNCTION_DECL, or call
3684 FUNCTION_DECL and then adjust the result value. Note, the result
3685 pointer adjusting thunk must perform a call to the thunked
3686 function, (or be implemented via passing some invisible parameter
3687 to the thunked function, which is modified to perform the
3688 adjustment just before returning).
3690 A thunk may perform either, or both, of the following operations:
3692 o Adjust the this or result pointer by a constant offset.
3693 o Adjust the this or result pointer by looking up a vcall or vbase offset
3696 A this pointer adjusting thunk converts from a base to a derived
3697 class, and hence adds the offsets. A result pointer adjusting thunk
3698 converts from a derived class to a base, and hence subtracts the
3699 offsets. If both operations are performed, then the constant
3700 adjustment is performed first for this pointer adjustment and last
3701 for the result pointer adjustment.
3703 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
3704 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
3705 used. For this pointer adjusting thunks, it is the vcall offset
3706 into the vtable. For result pointer adjusting thunks it is the
3707 binfo of the virtual base to convert to. Use that binfo's vbase
3710 It is possible to have equivalent covariant thunks. These are
3711 distinct virtual covariant thunks whose vbase offsets happen to
3712 have the same value. THUNK_ALIAS is used to pick one as the
3713 canonical thunk, which will get all the this pointer adjusting
3714 thunks attached to it. */
