474 Usage of language-independent fields in a language-dependent manner:
477 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
478 forth as a substitute for the mark bits provided in `lang_type'.
479 At present, only the six low-order bits are used.
482 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS.
483 For a POINTER_TYPE (to a METHOD_TYPE), this is TYPE_PTRMEMFUNC_TYPE.
484 For an ENUMERAL_TYPE, BOUND_TEMPLATE_TEMPLATE_PARM_TYPE,
485 RECORD_TYPE or UNION_TYPE this is TYPE_TEMPLATE_INFO,
488 For a binfo, this is a TREE_LIST. There is an entry for each
489 virtual function declared either in BINFO or its direct and
490 indirect primary bases.
492 The BV_DELTA of each node gives the amount by which to adjust the
493 `this' pointer when calling the function. If the method is an
494 overridden version of a base class method, then it is assumed
495 that, prior to adjustment, the this pointer points to an object
498 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
499 index of the vcall offset for this entry.
501 The BV_FN is the declaration for the virtual function itself.
503 If BV_LOST_PRIMARY is set, it means that this entry is for a lost
504 primary virtual base and can be left null in the vtable.
507 This is an expression with POINTER_TYPE that gives the value
508 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
509 to extract the VAR_DECL for the complete vtable.
512 This field is NULL for a non-virtual function. For a virtual
513 function, it is eventually set to an INTEGER_CST indicating the
514 index in the vtable at which this function can be found. When
515 a virtual function is declared, but before it is known what
516 function is overridden, this field is the error_mark_node.
518 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
519 the virtual function this one overrides, and whose TREE_CHAIN is
520 the old DECL_VINDEX. */

4685 pointer adjusting thunk must perform a call to the thunked
4686 function, (or be implemented via passing some invisible parameter
4687 to the thunked function, which is modified to perform the

4692 o Adjust the this or result pointer by a constant offset.
4693 o Adjust the this or result pointer by looking up a vcall or vbase offset
4696 A this pointer adjusting thunk converts from a base to a derived
4697 class, and hence adds the offsets. A result pointer adjusting thunk
4698 converts from a derived class to a base, and hence subtracts the
4699 offsets. If both operations are performed, then the constant
4700 adjustment is performed first for this pointer adjustment and last
4701 for the result pointer adjustment.

4706 into the vtable. For result pointer adjusting thunks it is the
