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

3913 The address of the ordinary FUNCTION_DECL is given by the
3914 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
3915 FUNCTION_DECL. The job of the thunk is to either adjust the this
3916 pointer before transferring control to the FUNCTION_DECL, or call
3917 FUNCTION_DECL and then adjust the result value. Note, the result
3918 pointer adjusting thunk must perform a call to the thunked
3919 function, (or be implemented via passing some invisible parameter
3920 to the thunked function, which is modified to perform the
3921 adjustment just before returning).
3923 A thunk may perform either, or both, of the following operations:
3925 o Adjust the this or result pointer by a constant offset.
3926 o Adjust the this or result pointer by looking up a vcall or vbase offset
3929 A this pointer adjusting thunk converts from a base to a derived
3930 class, and hence adds the offsets. A result pointer adjusting thunk
3931 converts from a derived class to a base, and hence subtracts the
3932 offsets. If both operations are performed, then the constant
3933 adjustment is performed first for this pointer adjustment and last
3934 for the result pointer adjustment.
3936 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
3937 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
3938 used. For this pointer adjusting thunks, it is the vcall offset
3939 into the vtable. For result pointer adjusting thunks it is the
3940 binfo of the virtual base to convert to. Use that binfo's vbase
3943 It is possible to have equivalent covariant thunks. These are
3944 distinct virtual covariant thunks whose vbase offsets happen to
3945 have the same value. THUNK_ALIAS is used to pick one as the
