previous changesets took a closer look at memory mgmt in the inorder model and sought to avoid
dynamic memory mgmt (for access to pipeline resources) as much as possible. For the regressions
that were run, the sims are about 2x speedup from changeset 7726 which is the last change
since the recent commits in Feb. (note: these regressions now are 4-issue CPUs instead of just 1-issue)

there are still only a few inorder benchmark but for the lengthier benchmarks (twolf and vortext)
the latest changes to how instruction scheduling (how instructions figure out what they want to
do on each pipeline stage in the inorder model) were able to improve performance by a nice
amount... The latest results for the inorder model process about 100k insts/second
(note: 58% is over the last time run on 64-bit pool machines at UM)

Exclude bzip2 for now. It works, it just takes too long to run.

This patch updates the output for regression tests that are carried out on
MESI_CMP_directory protocol. The changes made to the protocol in order to
remove the bugs present result in regression failure for the 60.rubytest.
Since the earlier protocol was incorrect, so we certainly cannot relay on the
earlier reference output. Hence, the update.

Coherence protocol change basically got rid
of UpgradeReqs in L2 caches, other minor
related cache stat changes.
|
|
Because the handling of the E state for multilevel caches
has changed, stats are affected for any non-ruby config
with caches, even uniprocessor simple CPU.

Small changes in tests with data races due to new object creation
order.
|
|
Rename 'responder_set' to 'use_default_range'.

Some subset of UpgradeReq messages shifted to the
new SCUpgradeReq type. Other than that there
are no significant differences.

I forgot to turn on ruby when updating the stats before.
