I agree with you. I did a few experiments, and it can take a very
long time for C2 compilation to kick in, especially because GCM is
glacially slow until the intrinsics are used.
I think this would be a generally useful enhancement to HotSpot,
and I'm kicking around an experimental patch which adds the
intrinsics to c1 and the interpreter.
