/* FIXME: Currently these are only used in getcontext.S, which is only used
   for a local unwinder, so we can use the compile-time ABI.  At a later date
   we will want all three here, to use for signal handlers.  Also, because
   of the three ABIs, gen-offsets.c can not quite generate this file.  */
