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

4833 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
4834 The address of the ordinary FUNCTION_DECL is given by the
4835 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
4836 FUNCTION_DECL. The job of the thunk is to either adjust the this
4837 pointer before transferring control to the FUNCTION_DECL, or call
4838 FUNCTION_DECL and then adjust the result value. Note, the result
4839 pointer adjusting thunk must perform a call to the thunked
4840 function, (or be implemented via passing some invisible parameter
4841 to the thunked function, which is modified to perform the
4842 adjustment just before returning).
4844 A thunk may perform either, or both, of the following operations:
4846 o Adjust the this or result pointer by a constant offset.
4847 o Adjust the this or result pointer by looking up a vcall or vbase offset
4850 A this pointer adjusting thunk converts from a base to a derived
4851 class, and hence adds the offsets. A result pointer adjusting thunk
4852 converts from a derived class to a base, and hence subtracts the
4853 offsets. If both operations are performed, then the constant
4854 adjustment is performed first for this pointer adjustment and last
4855 for the result pointer adjustment.
4857 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
4858 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
4859 used. For this pointer adjusting thunks, it is the vcall offset
4860 into the vtable. For result pointer adjusting thunks it is the
4861 binfo of the virtual base to convert to. Use that binfo's vbase
4864 It is possible to have equivalent covariant thunks. These are
4865 distinct virtual covariant thunks whose vbase offsets happen to
4866 have the same value. THUNK_ALIAS is used to pick one as the
4867 canonical thunk, which will get all the this pointer adjusting
