Yes. There are people working on the MIPS backend. But I'm not aware
of anyone doing MIPS 64-bit work. We are always looking forward for
improvements, so fell free to send patches and contribute. Be sure to
read http://llvm.org/docs/DeveloperPolicy.html before sending patches
and try to keep them small and feature contained as possible (with
testcases), so it's easy to review and integrate.

Looking forward to see your patches!
Cheers,
