Hi Shi-Hua:
Thanks, generally it's LGTM, just a few coding style issues. I've
fixed that and committed this time,
but just let you know where you should update your coding style.
And you could use git clang-format and use /contrib/clang-format
as format file to save
your time to indent that.

The crypto extension have several shorthand extensions that don't consist of
any extra instructions.
Take zk for example, while the extension would imply zkn, zkr, zkt.
The 3 extensions should also combine back into zk to maintain the canonical
order in isa strings.
