597 : Usage of language-independent fields in a language-dependent manner:
598 :
599 : TYPE_ALIAS_SET

601 : forth as a substitute for the mark bits provided in `lang_type'.
602 : At present, only the six low-order bits are used.
603 :
604 : TYPE_LANG_SLOT_1
605 : For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS.
606 : For a POINTER_TYPE (to a METHOD_TYPE), this is TYPE_PTRMEMFUNC_TYPE.
607 : For an ENUMERAL_TYPE, BOUND_TEMPLATE_TEMPLATE_PARM_TYPE,
608 : RECORD_TYPE or UNION_TYPE this is TYPE_TEMPLATE_INFO,
609 :
610 : BINFO_VIRTUALS
611 : For a binfo, this is a TREE_LIST. There is an entry for each
612 : virtual function declared either in BINFO or its direct and
613 : indirect primary bases.
614 :
615 : The BV_DELTA of each node gives the amount by which to adjust the
616 : `this' pointer when calling the function. If the method is an
617 : overridden version of a base class method, then it is assumed
618 : that, prior to adjustment, the this pointer points to an object
619 : of the base class.
620 :
621 : The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
622 : index of the vcall offset for this entry.
623 :
624 : The BV_FN is the declaration for the virtual function itself.
625 :
626 : If BV_LOST_PRIMARY is set, it means that this entry is for a lost
627 : primary virtual base and can be left null in the vtable.
628 :
629 : BINFO_VTABLE
630 : This is an expression with POINTER_TYPE that gives the value
631 : to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
632 : to extract the VAR_DECL for the complete vtable.
633 :
634 : DECL_VINDEX
635 : This field is NULL for a non-virtual function. For a virtual
636 : function, it is eventually set to an INTEGER_CST indicating the
637 : index in the vtable at which this function can be found. When
638 : a virtual function is declared, but before it is known what
639 : function is overridden, this field is the error_mark_node.
640 :
641 : Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
642 : the virtual function this one overrides, and whose TREE_CHAIN is
643 : the old DECL_VINDEX. */
