With that statement?  Nothing.  However:

     && (((val[0] & 0x80) && ! (val[0] & 0xffffff00))

this is assuming that 0xffffff00 constitutes the balance of
the long, which is not the case on Alpha.  Use ~(long)0xff.

Of course, now that I actually looked at the whole movdi pattern,
I see that I misinterpreted what bug you were fixing.  :-/
Your patch is ok.  There's another bug in there though, which
is the one I'm talking about above.
