syscall-emul: Move memState into its own file
It would be a good idea to try to figure out why, since it doesn't *look* like
this change was intended to move things around in memory or otherwise change
simulated behavior.

Line everything up again.
|
|
The EIOProcess class was removed recently and it was the only other class
which derived from Process. Since every Process invocation is also a
LiveProcess invocation, it makes sense to simplify the organization by
combining the fields from LiveProcess into Process.
|
|
|
|
|
|
Reflect the removal of the syscall tracking.
|
|
No one appears to be using it, and it is causing build issues
and increases the development and maintenance effort.
|
|
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.

Remove test reference files that are not generated any more:
* chair.cook.ppm: This file should be generated by eon and not
mcf, so it shouldn't be included as an output from mcf.
* system.pc.terminal: The terminal device has been renamed so this
file is no longer generated.

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.
|
|
Additional auxv entries leads to more instructions in start-up
while walking the list, along with different cache conflicts
wrt stack entries.
|
|
|
|
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.

The fs/80.solaris-boot/sparc/solaris/t1000-simple-atomic test was
broken for so long that, now that it's working again, the stats
output is out of date. This changeset updates the outputs, on
the assumption that the stats changes are all valid differences
due to other changes made while it was broken.

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?).
