And yes, we’d like to as well contribute our code along with mips64 code from Loongson. Of more precisely, on top, since we have chosen the #ifdef way. So that requires Loongson to be the first to put the code into the repos

The port is almost complete for template interpreter and c2. We’re in bug-fixing phase now
We did not yet started c1. specifically in order to avoid clash with your implementation during the merge

Soon we’ll be running our own code clearance tests so the results might be be helpful for you as well, since it should fix (or prove there are no) some of  the concerns OpenJDK government is imposing on the contributions. We’ll let you know the results once they are ready

We did not consider contributing into external repos, although it might make sense. Please let us discuss that internally first
