+       * ia64-tdep.c (ia64_frameless_function_invocation): Implement.
+       * config/ia64/linux.mh (NATDEPFILES): Use thread-db.o and lin-lwp.o
+       for thread support instead of linux-thread.o and lin-thread.o.
+       * config/ia64/nm-linux.h (PREPARE_TO_PROCEED, GET_THREAD_SIGNALS,
+       ATTACH_LWP): Define to use the following lin-lwp.c functions...
+       (lin_lwp_prepare_to_proceed, lin_thread_get_thread_signals,
+       lin_lwp_attach_lwp): Declare.
