145 Usage of language-independent fields in a language-dependent manner:
147 TYPE_ALIAS_SET
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.
152 TYPE_LANG_SLOT_1
153 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
154 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS
156 BINFO_VIRTUALS
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
165 of the base class.
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.
172 If BV_LOST_PRIMARY is set, it means that this entry is for a lost
173 primary virtual base and can be left null in the vtable.
175 BINFO_VTABLE
176 This is an expression with POINTER_TYPE that gives the value
177 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
178 to extract the VAR_DECL for the complete vtable.
180 DECL_VINDEX
181 This field is NULL for a non-virtual function. For a virtual
182 function, it is eventually set to an INTEGER_CST indicating the
183 index in the vtable at which this function can be found. When
184 a virtual function is declared, but before it is known what
185 function is overridden, this field is the error_mark_node.
187 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
188 the virtual function this one overrides, and whose TREE_CHAIN is
189 the old DECL_VINDEX. */

3683 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
3684 The address of the ordinary FUNCTION_DECL is given by the
3685 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
3686 FUNCTION_DECL. The job of the thunk is to either adjust the this
3687 pointer before transferring control to the FUNCTION_DECL, or call
3688 FUNCTION_DECL and then adjust the result value. Note, the result
3689 pointer adjusting thunk must perform a call to the thunked
3690 function, (or be implemented via passing some invisible parameter
3691 to the thunked function, which is modified to perform the
3692 adjustment just before returning).
3694 A thunk may perform either, or both, of the following operations:
3696 o Adjust the this or result pointer by a constant offset.
3697 o Adjust the this or result pointer by looking up a vcall or vbase offset
3698 in the vtable.
3700 A this pointer adjusting thunk converts from a base to a derived
3701 class, and hence adds the offsets. A result pointer adjusting thunk
3702 converts from a derived class to a base, and hence subtracts the
3703 offsets. If both operations are performed, then the constant
3704 adjustment is performed first for this pointer adjustment and last
3705 for the result pointer adjustment.
3707 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
3708 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
3709 used. For this pointer adjusting thunks, it is the vcall offset
3710 into the vtable. For result pointer adjusting thunks it is the
3711 binfo of the virtual base to convert to. Use that binfo's vbase
3712 offset.
3714 It is possible to have equivalent covariant thunks. These are
3715 distinct virtual covariant thunks whose vbase offsets happen to
3716 have the same value. THUNK_ALIAS is used to pick one as the
3717 canonical thunk, which will get all the this pointer adjusting
3718 thunks attached to it. */
