Thanks for the reviews.
But it looks like the test is very, very slow on ppc64  machines.
Does it make sense to have such a slow test on ppc64  ?  Looks like the test is related to special CPU features (avx512vl, f16c
).
In other tests I find the following

TestAllFloat16ToFloat.java
* @requires (vm.cpu.features ~= ".*avx512vl.*" | vm.cpu.features ~= ".*f16c.*") | os.arch == "aarch64"



should we do this here too ?
