AFAIK, MIPS doesn't support NEON. But that doesn't explain your
problem, which is probably due to hand-crafted IR.

Can you provide the full IR, with header and everything? Also the
command line that you're using with the LLVM tool you're using to
compile (llc?lli?).

It'd also be good to know how you generated that IR in the frist
place. Was it a tool? A front-end? Hand-crafted?
