601 : Usage of language-independent fields in a language-dependent manner:
602 :
603 : TYPE_ALIAS_SET
604 : This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
605 : forth as a substitute for the mark bits provided in `lang_type'.
606 : At present, only the six low-order bits are used.
607 :
608 : TYPE_LANG_SLOT_1
609 : For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS.
610 : For a POINTER_TYPE (to a METHOD_TYPE), this is TYPE_PTRMEMFUNC_TYPE.
611 : For an ENUMERAL_TYPE, BOUND_TEMPLATE_TEMPLATE_PARM_TYPE,
612 : RECORD_TYPE or UNION_TYPE this is TYPE_TEMPLATE_INFO,
613 :
614 : BINFO_VIRTUALS
615 : For a binfo, this is a TREE_LIST. There is an entry for each
616 : virtual function declared either in BINFO or its direct and
617 : indirect primary bases.
618 :
619 : The BV_DELTA of each node gives the amount by which to adjust the
620 : `this' pointer when calling the function. If the method is an
621 : overridden version of a base class method, then it is assumed
622 : that, prior to adjustment, the this pointer points to an object
623 : of the base class.
624 :
625 : The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
626 : index of the vcall offset for this entry.
627 :
628 : The BV_FN is the declaration for the virtual function itself.
629 :
630 : If BV_LOST_PRIMARY is set, it means that this entry is for a lost
631 : primary virtual base and can be left null in the vtable.
632 :
633 : BINFO_VTABLE
634 : This is an expression with POINTER_TYPE that gives the value
635 : to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
636 : to extract the VAR_DECL for the complete vtable.
637 :
638 : DECL_VINDEX
639 : This field is NULL for a non-virtual function. For a virtual
640 : function, it is eventually set to an INTEGER_CST indicating the
641 : index in the vtable at which this function can be found. When
642 : a virtual function is declared, but before it is known what
643 : function is overridden, this field is the error_mark_node.
644 :
645 : Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
646 : the virtual function this one overrides, and whose TREE_CHAIN is
647 : the old DECL_VINDEX. */
