Dave,
Have a look at how the LogTM release handles begin/end transaction instructions. It uses the simics "magic instruction" hap, which can be passed a parameter through the value used by the sethi instruction. You might be able to leverage this functionality for your prefetching hints.

Regards,
Dan

Hello,

I'm looking into ways to establish interaction between
Ruby and benchmarks. For example, a data-intensive
benchmark would provide hints to Ruby, such as when it
would request data or modify it. This hint would be
recognized by Ruby as an event, and would result in
some actions. So, these hints would be predetermined
and the programmer would insert them while coding
benchmarks. Is it possible to implement such
interaction in GEMS? If so, could you please give me
some pointers.

Thanks.

Dave
