Hi Vilas,
Are the diffs complete? The max_inst option never appears in
Options.py but it's used in Simulation.py
Thanks,

As an aside, if you want to fast forward 300M instructions and not
necessarily 300M cycles, it would be good to be able to specify that
directly... didn't we just have a thread on the mailing list about
that? I don't think it's in the code right now, but did someone out
there add it? If so, would you mind contributing the code back?
I added this functionality to Simulation.py and Options.py. I use --
fast_forward on its own to create checkpoints, and then with --
standard_switch to warmup caches. I've attached the diffs.
A word of caution: I had to back out some of my other changes to
Simulation.py to create this diff, so I haven't tested this on its
own. But it should be really close to what is needed.
