The following two sub-tests failed on Nvidia Grace machine(128-bit SVE).

  compiler/loopopts/superword/TestReductions.java#force-vectorization
  compiler/loopopts/superword/TestReductions.java#vanilla

Note that this test case can pass if -XX:UseSVE=0 is used.

Here shows the snippet of the error log:
