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

3903 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
3904 The address of the ordinary FUNCTION_DECL is given by the
3905 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
3906 FUNCTION_DECL. The job of the thunk is to either adjust the this
3907 pointer before transferring control to the FUNCTION_DECL, or call
3908 FUNCTION_DECL and then adjust the result value. Note, the result
3909 pointer adjusting thunk must perform a call to the thunked
3910 function, (or be implemented via passing some invisible parameter
3911 to the thunked function, which is modified to perform the
3912 adjustment just before returning).
3914 A thunk may perform either, or both, of the following operations:
3916 o Adjust the this or result pointer by a constant offset.
3917 o Adjust the this or result pointer by looking up a vcall or vbase offset
3920 A this pointer adjusting thunk converts from a base to a derived
3921 class, and hence adds the offsets. A result pointer adjusting thunk
3922 converts from a derived class to a base, and hence subtracts the
3923 offsets. If both operations are performed, then the constant
3924 adjustment is performed first for this pointer adjustment and last
3925 for the result pointer adjustment.
3927 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
3928 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
3929 used. For this pointer adjusting thunks, it is the vcall offset
3930 into the vtable. For result pointer adjusting thunks it is the
3931 binfo of the virtual base to convert to. Use that binfo's vbase
3934 It is possible to have equivalent covariant thunks. These are
3935 distinct virtual covariant thunks whose vbase offsets happen to
3936 have the same value. THUNK_ALIAS is used to pick one as the
3937 canonical thunk, which will get all the this pointer adjusting
