Comment 1 Andrew Pinski 2006-08-30 05:01:52 UTC 
Confirmed, this was added on the mainline but an easy search of ChangeLog could not find it because the changeLog was incomplete:
        * target-def.h: New target hook function_value.
 

Note I think it is the same behavior as the FUNCTION_VALUE macro, well close.  It also handles FUNCTION_OUTGOING_VALUE.
Here is the default one:
rtx
default_function_value (tree ret_type ATTRIBUTE_UNUSED,
                        tree fn_decl_or_type,
                        bool outgoing ATTRIBUTE_UNUSED)
{
  /* The old interface doesn't handle receiving the function type.  */
  if (fn_decl_or_type
      && !DECL_P (fn_decl_or_type))
    fn_decl_or_type = NULL;

#ifdef FUNCTION_OUTGOING_VALUE
  if (outgoing)
    return FUNCTION_OUTGOING_VALUE (ret_type, fn_decl_or_type);
#endif

#ifdef FUNCTION_VALUE
  return FUNCTION_VALUE (ret_type, fn_decl_or_type);
#else
  return NULL_RTX;
#endif
}
