You could *temporarily* turn the changes from 8592 to 8737 into
patches with qimport, qpop them, use hg update to move somewhere else,
and then qpush them. Be VERY CAREFUL while doing this. Don't commit
anything in that tree you intend to use anywhere else. Move work from
there to a unadulterated tree with patch files. The problem is that
once you turn a real change into a patch, I'm pretty sure it will
never be the same change again in mercurial's eyes. If that made it
into the main repository somehow, I'm sure lots of bad and confusing
things would happen.
Generally speaking, my SE/FS changes *shouldn't* have changed any
simulation behavior except maybe some stats about miscregs being
accessed more or less often in some cases since the code is always
there now. If you find that it does, that would be a great place to
look for your bug. There's been only one real live bug that came out
of the SE/FS merge so far as far as I know, but be careful you're not
hitting that if you're immediately after the merge. I vaguely remember
that being a failing assert so you're probably not.

Quoting Nilay Vaish <[email protected]>:
I am facing a peculiar problem in bisecting the repo for a
particular problem. In January, I committed a few patches to the o3
cpu, just after Gabe's commits for SE/FS merger. When I committed
those patches, I was able to boot a 4 core, x86, o3 cpu, ruby
system. But it seems I was working with a repo that did not had
Gabe's patches.
A couple of days back I tried booting the same system again (with
the latest repo and with the repo when I had just committed those
patches), and it does not work. I get some error about "bad page
state in process swapper". I back ported the o3 cpu patches to the
version just before Gabe's commits i.e. 8737:770ccf3af571, this
allowed me to boot the system.
I need to figure out what is going on wrong when I try to work with
8824:a42647b4a6b6. Since Gabe committed most of his patches over the
version 8592:30a97c4198df, I am not able to bisect the repo, as the
patches between 8592 and 8737 are removed when I update to any
version greater than 8737. I not sure how to bisect the repo so that
I can figure out which patch is causing the problem.
Does any one has some suggestion on how to do this?
Thanks
Nilay
