These instructions definitely need intrinsics, a way to get at them through altivec.h and support in PPCISelLowering.cpp (getVectorCompareInfo). Of course, we are only doing the ASM support at this time, but I think this would be the right time to put a note somewhere about what else is needed for these instructions. Perhaps a file named along the lines of P9AdditionalSupportReq.txt in lib/Target/PowerPC/.
