------- Comment #3 from rguenth at gcc dot gnu dot org  2009-10-05 09:53 -------
Not yet fixed.  We still have

  if (CODE_CONTAINS_STRUCT (code, TS_OPTIMIZATION))
    {
      /* FIXME lto.  Not handled yet.  */
      gcc_unreachable ();
    }

  if (CODE_CONTAINS_STRUCT (code, TS_TARGET_OPTION))
    {
      /* FIXME lto.  Not handled yet.  */
      gcc_unreachable ();
    }

For 4.5 this at least needs to become a sorry().

We now print

t.i:3:1: sorry, unimplemented: gimple bytecode streams do not support the
optimization attribute

Thus fixed.
