    Description

      In our recent tests on AArch64 CPUs with 512-bit SVE, we see Hotspot jtreg `compiler/loopopts/superword/TestDependencyOffsets.java` has a large number of IR check failures. The reason is that many of the test loops in the jtreg cannot be vectorized on 512-bit SVE due to data dependence but the test code assumes they can.
