517 Usage of language-independent fields in a language-dependent manner:
520 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
521 forth as a substitute for the mark bits provided in `lang_type'.
522 At present, only the six low-order bits are used.
525 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS.
526 For a POINTER_TYPE (to a METHOD_TYPE), this is TYPE_PTRMEMFUNC_TYPE.
527 For an ENUMERAL_TYPE, BOUND_TEMPLATE_TEMPLATE_PARM_TYPE,
528 RECORD_TYPE or UNION_TYPE this is TYPE_TEMPLATE_INFO,
531 For a binfo, this is a TREE_LIST. There is an entry for each
532 virtual function declared either in BINFO or its direct and
533 indirect primary bases.
535 The BV_DELTA of each node gives the amount by which to adjust the
536 `this' pointer when calling the function. If the method is an
537 overridden version of a base class method, then it is assumed
538 that, prior to adjustment, the this pointer points to an object
541 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
542 index of the vcall offset for this entry.
544 The BV_FN is the declaration for the virtual function itself.
546 If BV_LOST_PRIMARY is set, it means that this entry is for a lost
547 primary virtual base and can be left null in the vtable.
550 This is an expression with POINTER_TYPE that gives the value
551 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
552 to extract the VAR_DECL for the complete vtable.
555 This field is NULL for a non-virtual function. For a virtual
556 function, it is eventually set to an INTEGER_CST indicating the
557 index in the vtable at which this function can be found. When
558 a virtual function is declared, but before it is known what
559 function is overridden, this field is the error_mark_node.
561 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
562 the virtual function this one overrides, and whose TREE_CHAIN is
563 the old DECL_VINDEX. */

4847 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
4848 The address of the ordinary FUNCTION_DECL is given by the
4849 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
4850 FUNCTION_DECL. The job of the thunk is to either adjust the this
4851 pointer before transferring control to the FUNCTION_DECL, or call
4852 FUNCTION_DECL and then adjust the result value. Note, the result
4853 pointer adjusting thunk must perform a call to the thunked
4854 function, (or be implemented via passing some invisible parameter
4855 to the thunked function, which is modified to perform the
4856 adjustment just before returning).
4858 A thunk may perform either, or both, of the following operations:
4860 o Adjust the this or result pointer by a constant offset.
4861 o Adjust the this or result pointer by looking up a vcall or vbase offset
4864 A this pointer adjusting thunk converts from a base to a derived
4865 class, and hence adds the offsets. A result pointer adjusting thunk
4866 converts from a derived class to a base, and hence subtracts the
4867 offsets. If both operations are performed, then the constant
4868 adjustment is performed first for this pointer adjustment and last
4869 for the result pointer adjustment.
4871 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
4872 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
4873 used. For this pointer adjusting thunks, it is the vcall offset
4874 into the vtable. For result pointer adjusting thunks it is the
4875 binfo of the virtual base to convert to. Use that binfo's vbase
4878 It is possible to have equivalent covariant thunks. These are
4879 distinct virtual covariant thunks whose vbase offsets happen to
4880 have the same value. THUNK_ALIAS is used to pick one as the
4881 canonical thunk, which will get all the this pointer adjusting
4882 thunks attached to it. */
