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

4821 A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
4822 The address of the ordinary FUNCTION_DECL is given by the
4823 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
4824 FUNCTION_DECL. The job of the thunk is to either adjust the this
4825 pointer before transferring control to the FUNCTION_DECL, or call
4826 FUNCTION_DECL and then adjust the result value. Note, the result
4827 pointer adjusting thunk must perform a call to the thunked
4828 function, (or be implemented via passing some invisible parameter
4829 to the thunked function, which is modified to perform the
4830 adjustment just before returning).
4832 A thunk may perform either, or both, of the following operations:
4834 o Adjust the this or result pointer by a constant offset.
4835 o Adjust the this or result pointer by looking up a vcall or vbase offset
4838 A this pointer adjusting thunk converts from a base to a derived
4839 class, and hence adds the offsets. A result pointer adjusting thunk
4840 converts from a derived class to a base, and hence subtracts the
4841 offsets. If both operations are performed, then the constant
4842 adjustment is performed first for this pointer adjustment and last
4843 for the result pointer adjustment.
4845 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
4846 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
4847 used. For this pointer adjusting thunks, it is the vcall offset
4848 into the vtable. For result pointer adjusting thunks it is the
4849 binfo of the virtual base to convert to. Use that binfo's vbase
4852 It is possible to have equivalent covariant thunks. These are
4853 distinct virtual covariant thunks whose vbase offsets happen to
4854 have the same value. THUNK_ALIAS is used to pick one as the
4855 canonical thunk, which will get all the this pointer adjusting
4856 thunks attached to it. */
