Although the changes focus on Arm SVE platform, we expect the ideas can also be applied to AVX-512 especially for the shared codes. It will be very helpful if you can give any comments from the side of AVX-512. And it will be very great if there is an optimal final solution for the masking support both for Arm SVE and AVX-512. So please help to have a look at it! Thanks so much!

We will continue working on the missing parts including other masked vector operations, mask generation operations and the mask operations. And currently we are looking at the deoptimization support for predicate registers. To avoid conflicts, it will be helpful if you could also share us any ideas or plans from your side. Thanks so much!

Hi, I have to force push all the codes again to resolve the conflicts due to the latest merging from jdk master. Thanks!
