Hi Kavya,

This looks like a bug! The RubyPrefetcher has never been regularly tested,
as far as I know. I would guess the place where these were updated got
deleted at some point and no one noticed. I'd try checking out a gem5 from
5 years ago and see if it's there. We would welcome a contribution fixing
this issue!

Cheers,
Jason
