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. -- rguenth at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC|rguenther at suse dot de |rguenth at gcc dot gnu dot | |org Target Milestone|--- |4.4.0 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38004 ^ permalink raw reply [flat|nested] 6+ messages in thread
