Hi Christopher,

I've send my patch to the mailing list. Sorry for the great delay in answers.

Do you think it is possible to implement another QEMU logger which will
make a record for every executed block,
Yes (this would just need to disable the TB linking optimisation,
which we've discussed providing a debug toggle for in another
thread).
Ok, I've implemented a mapping between disassembled forms of instructions and
executed TBs.
Now my logger does "loop unrolling" successfully.
This sounds like it solves the same issue as -d nochain but in what's probably
a more time efficient manner. Are you able to share your implementation?
In which way should I share it? Am I need to create a patch and send it to
mailing list?
That would be ideal. If you're not familiar with the process, just let me know
and I'd be happy to help.

Thanks,
Christopher Covington
