I think that makes sense. I'll put a patch on RB for this soon.

Hi all,
Then, considering Arthur's answer, I suppose that we can remove
BPredUnit::predictInOrder() rather than updating and not testing it.

I suppose it was called by the InOrder CPU once upon a time. Now the
Minor CPU uses the same branch prediction code as the o3 CPU, which may
have led to the current inconsistencies in how branch predictors handle
out-of-order mispredictions (or not :)).

Hi Fernando,
I don't know what he original use of predictInOrder was, but you're right,
it doesn't look like it's in use now. You may be able to figure out what it
was used for by inferring its function from the code.

Hi Fernando,
I have no idea, off the top of my head. I'd have to look into the code
and/or the history of the file to figure it out.
I'm busy with an ISCA submission right now, but I can find time to look
into this in a week or so.
Cheers,

Hi Jason,
I've been working a bit on the integration, and I wondered what is and
where this method is used:
BPredUnit::predictInOrder()
I greped the source and built code and did not find a calling point.
Thanks,

Hi Fernando,
Yes, it seems like a good idea to include a TAGE predictor in gem5. Please
make patches and post them to the reviewboard. We welcome the contribution.
Additionally, I believe there was a recent email about a possible bug when
updating the branch predictor state on a mis-speculation.
Hello all,
I'd like to know if the gem5 community would like to have a TAGE branch
prediction in gem5.
In my branch it seems to be working, so if you give me a positive feedback
I may spend some spare time to rebase and test the patch over mainstream.
More specifically, I took the CBP2016 winner
