------- 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.
