Mostly just splitting out the floats ops and corresponding
reads/writes.

Two of the switcheroo tests were accidentally removed due to
unexpected Mercurial behavior.

The switcheroo tests only really serve to check functional
correctness. Checking for stat differences in them just increases the
size of reference diffs.

Switcheroo and checkpoint tests should generally be considered to be
successful if they run to completion. Remove all reference output
files from the switcheroo and checkopint tests to make them purely
functional.

Removed unused stats, now counting WriteLineReq, and changed how
uncacheable writes are handled while responses are outstanding.
|
|
Small changes to the branch predictor and BTB caused stats changes
throughout.
|
|
SE O3 runs see an additional reg read per mmap() call.
|
|
Update stats to match current behaviour. As a result of the earlier
conflict check we are seeing a few prefetch requests being ignored
before being sent as upward snoops.

A couple of the long regressions have been showing as CHANGED
since 11244:a2af58a06c4e despite the updates in 11245:1c5102c0a7a9.
The x86 regression looks like it was just missed, but it's not clear
why the ARM one is giving different results (perhaps a non-determinism
between zizzer and wherever the updated results were run?).

The Minor draining fixes affect perturb the timing slightly since it
affects how the simulator is drained. Update reference statistics to
reflect this expected change.

This update includes the changes to whole-line writes, the refinement
of Read to ReadClean and ReadShared, the introduction of CleanEvict
for snoop-filter tracking, and updates to the DRAM command scheduler
for bank-group-aware scheduling.
Needless to say, almost every regression is affected.

The addition of a virtual timer affects stats in minor and o3.
|

Only one regression is affected.

Very small differences in IQ-specific O3 stats.
|
|
Very small changes to iew.predictedNotTakenIncorrect
and iew.branchMispredicts. Looks like similar updates
were committed on April 3 (changeset 235ff1c046df), but
only for the quick tests.

A few regressions were still considered long, but finished well within
the 180 seconds. They are only a handful (mostly mcf in atomic).

A recent changeset of mine (http://repo.gem5.org/gem5/rev/4cfe55719da5)
inadvertently fixed a bug in the Minor CPU model which caused it to treat
software prefetches as regular loads. Prior to this changeset, Minor
did an ad-hoc generation of memory commands that left out the PF check;
because it now uses the common code that the other CPU models use,
it generates prefetches properly. These stat changes reflect the fact
that the Minor model now issues SoftPFReqs.
