Some vector tests are showing failures when running with MaxVectorSize < 16. E.g.:
make run-test TEST=jdk/incubator/vector/Float64VectorTests.java JTREG="VM_OPTIONS=-XX:MaxVectorSize=8"
On x86_64:
ExceptionInInitializerError: Exception java.lang.AssertionError [in thread "MainThread"]
at jdk.incubator.vector/jdk.incubator.vector.CPUFeatures$X64.<clinit>(CPUFeatures.java:78)
On PPC64:
assert(ov->field_size() == 1) failed: jdk/incubator/vector/Int64Vector not a vector
VectorSupport::allocate_vector(InstanceKlass*, frame*, RegisterMap*, ObjectValue*, JavaThread*)+0x478 (vectorSupport.cpp:162)
Does it make sense at all to use EnableVectorSupport with MaxVectorSize < 16?
