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

3356 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
3357 The address of the ordinary FUNCTION_DECL is given by the
3358 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
3359 FUNCTION_DECL. The job of the thunk is to either adjust the this
3360 pointer before transferring control to the FUNCTION_DECL, or call
3361 FUNCTION_DECL and then adjust the result value. Note, the result
3362 pointer adjusting thunk must perform a call to the thunked
3363 function, (or be implemented via passing some invisible parameter
3364 to the thunked function, which is modified to perform the
3365 adjustment just before returning).
3367 A thunk may perform either, or both, of the following operations:
3369 o Adjust the this or result pointer by a constant offset.
3370 o Adjust the this or result pointer by looking up a vcall or vbase offset
3373 A this pointer adjusting thunk converts from a base to a derived
3374 class, and hence adds the offsets. A result pointer adjusting thunk
3375 converts from a derived class to a base, and hence subtracts the
3376 offsets. If both operations are performed, then the constant
3377 adjustment is performed first for this pointer adjustment and last
3378 for the result pointer adjustment.
3380 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
3381 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
3382 used. For this pointer adjusting thunks, it is the vcall offset
3383 into the vtable. For result pointer adjusting thunks it is the
3384 binfo of the virtual base to convert to. Use that binfo's vbase
3387 It is possible to have equivalent covariant thunks. These are
3388 distinct virtual covariant thunks whose vbase offsets happen to
3389 have the same value. THUNK_ALIAS is used to pick one as the
