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

3924 The address of the ordinary FUNCTION_DECL is given by the
3925 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
3926 FUNCTION_DECL. The job of the thunk is to either adjust the this
3927 pointer before transferring control to the FUNCTION_DECL, or call
3928 FUNCTION_DECL and then adjust the result value. Note, the result
3929 pointer adjusting thunk must perform a call to the thunked
3930 function, (or be implemented via passing some invisible parameter
3931 to the thunked function, which is modified to perform the
3932 adjustment just before returning).
3934 A thunk may perform either, or both, of the following operations:
3936 o Adjust the this or result pointer by a constant offset.
3937 o Adjust the this or result pointer by looking up a vcall or vbase offset
3940 A this pointer adjusting thunk converts from a base to a derived
3941 class, and hence adds the offsets. A result pointer adjusting thunk
3942 converts from a derived class to a base, and hence subtracts the
3943 offsets. If both operations are performed, then the constant
3944 adjustment is performed first for this pointer adjustment and last
3945 for the result pointer adjustment.
3947 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
3948 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
3949 used. For this pointer adjusting thunks, it is the vcall offset
3950 into the vtable. For result pointer adjusting thunks it is the
3951 binfo of the virtual base to convert to. Use that binfo's vbase
3954 It is possible to have equivalent covariant thunks. These are
3955 distinct virtual covariant thunks whose vbase offsets happen to
3956 have the same value. THUNK_ALIAS is used to pick one as the
