I don't know that gzip is still broken.

It looks like gzip and parser failed in the most recent nightlies

(March 11th). They both passed on Feb 27th and didn't run on the
March 6th.
In that time, I changed how the pagetable walker works slightly,
although that won't be used in SE mode, changed how PCI config
space is
handled which also shouldn't affect SE mode.
I also marked prefetches as prefetches, marked IO reads and writes
as
non-speculative, and started decoding a unofficial and poorly
documented
floating point instruction. These -shouldn't- matter in SE, other
than
maybe the prefetches, but it's possible something was misspeculated
that
behaved differently and threw things off slightly.

Yeah, the differences are that more non-speculative instructions
were
floating around and then squashed, and some other small changes
which
are probably due to that. All those other differences show up as
less
than 0.00% change. I think there were just mispeculated IO reads
and
writes (IN and OUT instructions, basically) which changed execution
slightly.
It sounds like you've already rerun parser at least. If your stats
differences sound like what I'm describing, please go ahead and
update
them. I should have run them again myself, but I must have either
forgotten to or assumed they wouldn't affect SE.

Looks like the parser x86 o3 regression fails without any changes

the head. Anyone seen this?
