------- Comment #2 from rguenth at gcc dot gnu dot org  2008-11-04 09:29 -------
I don't see how the patch can make a difference only on ia64.  Note that on
x86_64 the loop isn't vectorized either -- even though the stats print there
is a vectorized loop.  It looks like the vectorized version gets removed
by cfgcleanup immediately.  Increasing the array size to 8 makes the vectorized
loop appear.
