; This test exercises the areMemAccessesTriviallyDisjoint hook.
; Test that the two stores are disjoint memory accesses. If the corresponding
; store machine instructions don't depend on each other, the second store should
; not appear in the successors list of the first one and the first one should
; not appear on the predecessors list of the second one.
