588 : :

591 : : virtual function declared either in BINFO or its direct and
592 : : indirect primary bases.
593 : :
594 : : The BV_DELTA of each node gives the amount by which to adjust the
595 : : `this' pointer when calling the function. If the method is an
596 : : overridden version of a base class method, then it is assumed
597 : : that, prior to adjustment, the this pointer points to an object
598 : : of the base class.
599 : :
600 : : The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
601 : : index of the vcall offset for this entry.
602 : :
603 : : The BV_FN is the declaration for the virtual function itself.
604 : :
605 : : If BV_LOST_PRIMARY is set, it means that this entry is for a lost
606 : : primary virtual base and can be left null in the vtable.
607 : :
608 : : BINFO_VTABLE
609 : : This is an expression with POINTER_TYPE that gives the value
610 : : to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
611 : : to extract the VAR_DECL for the complete vtable.
612 : :
613 : : DECL_VINDEX
614 : : This field is NULL for a non-virtual function. For a virtual
615 : : function, it is eventually set to an INTEGER_CST indicating the
616 : : index in the vtable at which this function can be found. When
617 : : a virtual function is declared, but before it is known what
618 : : function is overridden, this field is the error_mark_node.
