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

4897 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
4898 The address of the ordinary FUNCTION_DECL is given by the
4899 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
4900 FUNCTION_DECL. The job of the thunk is to either adjust the this
4901 pointer before transferring control to the FUNCTION_DECL, or call
4902 FUNCTION_DECL and then adjust the result value. Note, the result
4903 pointer adjusting thunk must perform a call to the thunked
4904 function, (or be implemented via passing some invisible parameter
4905 to the thunked function, which is modified to perform the
4906 adjustment just before returning).
4908 A thunk may perform either, or both, of the following operations:
4910 o Adjust the this or result pointer by a constant offset.
4911 o Adjust the this or result pointer by looking up a vcall or vbase offset
4914 A this pointer adjusting thunk converts from a base to a derived
4915 class, and hence adds the offsets. A result pointer adjusting thunk
4916 converts from a derived class to a base, and hence subtracts the
4917 offsets. If both operations are performed, then the constant
4918 adjustment is performed first for this pointer adjustment and last
4919 for the result pointer adjustment.
4921 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
4922 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
4923 used. For this pointer adjusting thunks, it is the vcall offset
4924 into the vtable. For result pointer adjusting thunks it is the
4925 binfo of the virtual base to convert to. Use that binfo's vbase
4928 It is possible to have equivalent covariant thunks. These are
4929 distinct virtual covariant thunks whose vbase offsets happen to
4930 have the same value. THUNK_ALIAS is used to pick one as the
4931 canonical thunk, which will get all the this pointer adjusting
