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. */

4719 converts from a derived class to a base, and hence subtracts the

4727 into the vtable. For result pointer adjusting thunks it is the

4732 distinct virtual covariant thunks whose vbase offsets happen to
