It's a good thing :-) Looks like lp64 should be removed from the xfail. That's why ppc64 and x86_64 XPASS on all three checks. sparc64 XPASSes only the first check (and not the other two alignment related checks) because it is a "vect_no_align" target. For the same reason ia64 doesn't have the two alignment related XPASSes. It remains to understand why ia64 still fails to vectorize the 2 loops - potentially this is not ilp64 related. Do you have the dump file generated by -fdump-tree-vect-details on ia64 for this testcase? dorit > Jack
