150 Usage of language-independent fields in a language-dependent manner:
153 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
154 forth as a substitute for the mark bits provided in `lang_type'.
155 At present, only the six low-order bits are used.
158 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
159 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS
162 For a binfo, this is a TREE_LIST. There is an entry for each
163 virtual function declared either in BINFO or its direct and
164 indirect primary bases.
166 The BV_DELTA of each node gives the amount by which to adjust the
167 `this' pointer when calling the function. If the method is an
168 overridden version of a base class method, then it is assumed
169 that, prior to adjustment, the this pointer points to an object
172 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
173 index of the vcall offset for this entry.
175 The BV_FN is the declaration for the virtual function itself.
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. */

3613 The address of the ordinary FUNCTION_DECL is given by the
3614 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
3615 FUNCTION_DECL. The job of the thunk is to either adjust the this
3616 pointer before transferring control to the FUNCTION_DECL, or call
3617 FUNCTION_DECL and then adjust the result value. Note, the result
3618 pointer adjusting thunk must perform a call to the thunked
3619 function, (or be implemented via passing some invisible parameter
3620 to the thunked function, which is modified to perform the
3621 adjustment just before returning).

3625 o Adjust the this or result pointer by a constant offset.
3626 o Adjust the this or result pointer by looking up a vcall or vbase offset
3629 A this pointer adjusting thunk converts from a base to a derived
3630 class, and hence adds the offsets. A result pointer adjusting thunk
3631 converts from a derived class to a base, and hence subtracts the
3632 offsets. If both operations are performed, then the constant
3633 adjustment is performed first for this pointer adjustment and last
3634 for the result pointer adjustment.
3636 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
3637 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
3638 used. For this pointer adjusting thunks, it is the vcall offset
3639 into the vtable. For result pointer adjusting thunks it is the
3640 binfo of the virtual base to convert to. Use that binfo's vbase
3643 It is possible to have equivalent covariant thunks. These are
3644 distinct virtual covariant thunks whose vbase offsets happen to
3645 have the same value. THUNK_ALIAS is used to pick one as the
