The only ones that should be present in the panama-vector repo and not present in the jdk repo are those that are auto-generated.

Now that we have the HotSpot compiler IR testing framework we don’t need to integrate as many micro-kind-benchmarks testing a few operations. Benchmarks that focus use-cases are better IMO.

Chiranmoy, if you have an algorithm/use-case using bit packing then submitting a benchmark for that could be very helpful.
