453 Usage of language-independent fields in a language-dependent manner:
456 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
457 forth as a substitute for the mark bits provided in `lang_type'.
458 At present, only the six low-order bits are used.
461 For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
462 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS
465 For a binfo, this is a TREE_LIST. There is an entry for each
466 virtual function declared either in BINFO or its direct and
467 indirect primary bases.
469 The BV_DELTA of each node gives the amount by which to adjust the
470 `this' pointer when calling the function. If the method is an
471 overridden version of a base class method, then it is assumed
472 that, prior to adjustment, the this pointer points to an object
475 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
476 index of the vcall offset for this entry.
478 The BV_FN is the declaration for the virtual function itself.
480 If BV_LOST_PRIMARY is set, it means that this entry is for a lost
481 primary virtual base and can be left null in the vtable.
484 This is an expression with POINTER_TYPE that gives the value
485 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
486 to extract the VAR_DECL for the complete vtable.
489 This field is NULL for a non-virtual function. For a virtual
490 function, it is eventually set to an INTEGER_CST indicating the
491 index in the vtable at which this function can be found. When
492 a virtual function is declared, but before it is known what
493 function is overridden, this field is the error_mark_node.
495 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
496 the virtual function this one overrides, and whose TREE_CHAIN is
497 the old DECL_VINDEX. */

4651 FUNCTION_DECL. The job of the thunk is to either adjust the this
4652 pointer before transferring control to the FUNCTION_DECL, or call
4653 FUNCTION_DECL and then adjust the result value. Note, the result
4654 pointer adjusting thunk must perform a call to the thunked
4655 function, (or be implemented via passing some invisible parameter
4656 to the thunked function, which is modified to perform the
4657 adjustment just before returning).

4661 o Adjust the this or result pointer by a constant offset.
4662 o Adjust the this or result pointer by looking up a vcall or vbase offset
4665 A this pointer adjusting thunk converts from a base to a derived
4666 class, and hence adds the offsets. A result pointer adjusting thunk
4667 converts from a derived class to a base, and hence subtracts the
4668 offsets. If both operations are performed, then the constant
4669 adjustment is performed first for this pointer adjustment and last
4670 for the result pointer adjustment.
4672 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
4673 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
4674 used. For this pointer adjusting thunks, it is the vcall offset
4675 into the vtable. For result pointer adjusting thunks it is the
4676 binfo of the virtual base to convert to. Use that binfo's vbase
4679 It is possible to have equivalent covariant thunks. These are
4680 distinct virtual covariant thunks whose vbase offsets happen to
