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

4913 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
4914 The address of the ordinary FUNCTION_DECL is given by the
4915 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
4916 FUNCTION_DECL. The job of the thunk is to either adjust the this
4917 pointer before transferring control to the FUNCTION_DECL, or call
4918 FUNCTION_DECL and then adjust the result value. Note, the result
4919 pointer adjusting thunk must perform a call to the thunked
4920 function, (or be implemented via passing some invisible parameter
4921 to the thunked function, which is modified to perform the
4922 adjustment just before returning).
4924 A thunk may perform either, or both, of the following operations:
4926 o Adjust the this or result pointer by a constant offset.
4927 o Adjust the this or result pointer by looking up a vcall or vbase offset
4930 A this pointer adjusting thunk converts from a base to a derived
4931 class, and hence adds the offsets. A result pointer adjusting thunk
4932 converts from a derived class to a base, and hence subtracts the
4933 offsets. If both operations are performed, then the constant
4934 adjustment is performed first for this pointer adjustment and last
4935 for the result pointer adjustment.
4937 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
4938 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
4939 used. For this pointer adjusting thunks, it is the vcall offset
4940 into the vtable. For result pointer adjusting thunks it is the
4941 binfo of the virtual base to convert to. Use that binfo's vbase
4944 It is possible to have equivalent covariant thunks. These are
4945 distinct virtual covariant thunks whose vbase offsets happen to
4946 have the same value. THUNK_ALIAS is used to pick one as the
4947 canonical thunk, which will get all the this pointer adjusting
