558 Usage of language-independent fields in a language-dependent manner:
561 This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
562 forth as a substitute for the mark bits provided in `lang_type'.
563 At present, only the six low-order bits are used.
566 For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS.
567 For a POINTER_TYPE (to a METHOD_TYPE), this is TYPE_PTRMEMFUNC_TYPE.
568 For an ENUMERAL_TYPE, BOUND_TEMPLATE_TEMPLATE_PARM_TYPE,
569 RECORD_TYPE or UNION_TYPE this is TYPE_TEMPLATE_INFO,
572 For a binfo, this is a TREE_LIST. There is an entry for each
573 virtual function declared either in BINFO or its direct and
574 indirect primary bases.
576 The BV_DELTA of each node gives the amount by which to adjust the
577 `this' pointer when calling the function. If the method is an
578 overridden version of a base class method, then it is assumed
579 that, prior to adjustment, the this pointer points to an object
582 The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
583 index of the vcall offset for this entry.
585 The BV_FN is the declaration for the virtual function itself.
587 If BV_LOST_PRIMARY is set, it means that this entry is for a lost
588 primary virtual base and can be left null in the vtable.
591 This is an expression with POINTER_TYPE that gives the value
592 to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
593 to extract the VAR_DECL for the complete vtable.
596 This field is NULL for a non-virtual function. For a virtual
597 function, it is eventually set to an INTEGER_CST indicating the
598 index in the vtable at which this function can be found. When
599 a virtual function is declared, but before it is known what
600 function is overridden, this field is the error_mark_node.
602 Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
603 the virtual function this one overrides, and whose TREE_CHAIN is
604 the old DECL_VINDEX. */

5064 The address of the ordinary FUNCTION_DECL is given by the
5065 DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
5066 FUNCTION_DECL. The job of the thunk is to either adjust the this
5067 pointer before transferring control to the FUNCTION_DECL, or call
5068 FUNCTION_DECL and then adjust the result value. Note, the result
5069 pointer adjusting thunk must perform a call to the thunked
5070 function, (or be implemented via passing some invisible parameter
5071 to the thunked function, which is modified to perform the
5072 adjustment just before returning).
5074 A thunk may perform either, or both, of the following operations:
5076 o Adjust the this or result pointer by a constant offset.
5077 o Adjust the this or result pointer by looking up a vcall or vbase offset
5080 A this pointer adjusting thunk converts from a base to a derived
5081 class, and hence adds the offsets. A result pointer adjusting thunk
5082 converts from a derived class to a base, and hence subtracts the
5083 offsets. If both operations are performed, then the constant
5084 adjustment is performed first for this pointer adjustment and last
5085 for the result pointer adjustment.
5087 The constant adjustment is given by THUNK_FIXED_OFFSET. If the
5088 vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
5089 used. For this pointer adjusting thunks, it is the vcall offset
5090 into the vtable. For result pointer adjusting thunks it is the
5091 binfo of the virtual base to convert to. Use that binfo's vbase
5094 It is possible to have equivalent covariant thunks. These are
5095 distinct virtual covariant thunks whose vbase offsets happen to
5096 have the same value. THUNK_ALIAS is used to pick one as the
