adding dependence from prefetch to load

Hi, I have a mips-like architecture which has prefetch instructions. I'm writing an optimization pass that inserts prefetch instructions for all array reads. The catch is that I'm trying to do this even if the reads are not in a loop. I have two questions: 1. Is there any work out there that
