568 : Usage of language-independent fields in a language-dependent manner:
569 :
570 : TYPE_ALIAS_SET
571 : This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
572 : forth as a substitute for the mark bits provided in `lang_type'.
573 : At present, only the six low-order bits are used.
574 :
575 : TYPE_LANG_SLOT_1
576 : For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS.
577 : For a POINTER_TYPE (to a METHOD_TYPE), this is TYPE_PTRMEMFUNC_TYPE.
578 : For an ENUMERAL_TYPE, BOUND_TEMPLATE_TEMPLATE_PARM_TYPE,
579 : RECORD_TYPE or UNION_TYPE this is TYPE_TEMPLATE_INFO,
580 :
581 : BINFO_VIRTUALS
582 : For a binfo, this is a TREE_LIST. There is an entry for each
583 : virtual function declared either in BINFO or its direct and
584 : indirect primary bases.
585 :
586 : The BV_DELTA of each node gives the amount by which to adjust the
587 : `this' pointer when calling the function. If the method is an
588 : overridden version of a base class method, then it is assumed
589 : that, prior to adjustment, the this pointer points to an object
590 : of the base class.
591 :
592 : The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
593 : index of the vcall offset for this entry.
594 :
595 : The BV_FN is the declaration for the virtual function itself.
596 :
597 : If BV_LOST_PRIMARY is set, it means that this entry is for a lost
598 : primary virtual base and can be left null in the vtable.
599 :
600 : BINFO_VTABLE
601 : This is an expression with POINTER_TYPE that gives the value
602 : to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
603 : to extract the VAR_DECL for the complete vtable.
604 :
605 : DECL_VINDEX
606 : This field is NULL for a non-virtual function. For a virtual
607 : function, it is eventually set to an INTEGER_CST indicating the
608 : index in the vtable at which this function can be found. When
609 : a virtual function is declared, but before it is known what
610 : function is overridden, this field is the error_mark_node.
611 :
612 : Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
613 : the virtual function this one overrides, and whose TREE_CHAIN is
614 : the old DECL_VINDEX. */
