Thanks, glad to hear that this addition might be beneficial for others
as well!

So, the s390x architecture (including vector instructions) are described
in the z/Architecture Principles of Operation. You can find the latest
publication at [1].
Regarding TCG internals/vector instruction support ... well, most
documentation is the code itself/implementing architectures. :)
Please let me know if you need more information.
Cheers!
