Hi,
It looks as if software prefetch instructions are ignored by the O3 model
in the m5 2.0 release (e.g. they 'execute' and 'commit' but do not impact
the microarchitectural state). In particular,
BaseDynInst<Impl>::prefetch(Addr addr, unsigned flags) does nothing.
How difficult would it be to re-enable swp?
Thanks,
Russ
