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

3709 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
3710 The address of the ordinary FUNCTION_DECL is given by the
3711 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
3712 FUNCTION_DECL. The job of the thunk is to either adjust the this
3713 pointer before transferring control to the FUNCTION_DECL, or call
3714 FUNCTION_DECL and then adjust the result value. Note, the result
3715 pointer adjusting thunk must perform a call to the thunked
3716 function, (or be implemented via passing some invisible parameter
3717 to the thunked function, which is modified to perform the
3718 adjustment just before returning).
3720 A thunk may perform either, or both, of the following operations:
3722 o Adjust the this or result pointer by a constant offset.
3723 o Adjust the this or result pointer by looking up a vcall or vbase offset
3726 A this pointer adjusting thunk converts from a base to a derived
3727 class, and hence adds the offsets. A result pointer adjusting thunk
3728 converts from a derived class to a base, and hence subtracts the
3729 offsets. If both operations are performed, then the constant
3730 adjustment is performed first for this pointer adjustment and last
3731 for the result pointer adjustment.
3733 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
3734 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
3735 used. For this pointer adjusting thunks, it is the vcall offset
3736 into the vtable. For result pointer adjusting thunks it is the
3737 binfo of the virtual base to convert to. Use that binfo's vbase
3740 It is possible to have equivalent covariant thunks. These are
3741 distinct virtual covariant thunks whose vbase offsets happen to
3742 have the same value. THUNK_ALIAS is used to pick one as the
3743 canonical thunk, which will get all the this pointer adjusting
3744 thunks attached to it. */
