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

4854 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
4855 The address of the ordinary FUNCTION_DECL is given by the
4856 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
4857 FUNCTION_DECL. The job of the thunk is to either adjust the this
4858 pointer before transferring control to the FUNCTION_DECL, or call
4859 FUNCTION_DECL and then adjust the result value. Note, the result
4860 pointer adjusting thunk must perform a call to the thunked
4861 function, (or be implemented via passing some invisible parameter
4862 to the thunked function, which is modified to perform the
4863 adjustment just before returning).
4865 A thunk may perform either, or both, of the following operations:
4867 o Adjust the this or result pointer by a constant offset.
4868 o Adjust the this or result pointer by looking up a vcall or vbase offset
4871 A this pointer adjusting thunk converts from a base to a derived
4872 class, and hence adds the offsets. A result pointer adjusting thunk
4873 converts from a derived class to a base, and hence subtracts the
4874 offsets. If both operations are performed, then the constant
4875 adjustment is performed first for this pointer adjustment and last
4876 for the result pointer adjustment.
4878 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
4879 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
4880 used. For this pointer adjusting thunks, it is the vcall offset
4881 into the vtable. For result pointer adjusting thunks it is the
4882 binfo of the virtual base to convert to. Use that binfo's vbase
4885 It is possible to have equivalent covariant thunks. These are
4886 distinct virtual covariant thunks whose vbase offsets happen to
4887 have the same value. THUNK_ALIAS is used to pick one as the
4888 canonical thunk, which will get all the this pointer adjusting
