> This test failed at cases test_reversebytes_short/int/long_transform2, which expected the ReversBytesV node, but nothing was finally found. On SVE system, we have a specific optimization, `ReverseBytesV (ReverseBytesV X MASK) MASK => X`, which eliminates both ReverseBytesV nodes. This optimization rule is specifically on hardware with native predicate support. See https://github.com/openjdk/jdk/pull/9623 for more details.

> As there is an SVE specific case TestReverseByteTransformsSVE.java, this patch simply marks TestReverseByteTransforms.java as non-SVE only.
>
> [TEST]
> jdk/incubator/vector, hotspot/compiler/vectorapi pass on SVE machine
