The test 'TestBufferVectorization.java' in the pre-submit tests failed, but it does not failed on my machine. The jit code of 'compiler.vectorization.TestBufferVectorization$TestBuffer::run' is  different after applying the patch: one loop predication is not allowed but another different loop predication is performed. So I agree with you that the patch is not complete, there must exist other latent bugs.
