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