It needs to wait until after SOSP though. We should see about getting you commit access some time. I don't have time to be a very good mentor at the moment, but maybe someone else could. For the 128-bit format used on sparc64, you probably need a separate implementation (or at least different constants), but hopefully that's not too hard once you've done it once. Dealing with our reduced precision on x86 is easy, since in that case you can just fall back on the ordinary sin() routine.
