Yeah, that sounds like the simplest way to handle it.
BTW, I'm also not sure about saying "default" in "show disassembler-options".
I don't think "set disassembler-options default" would work?
Do we still need that given the option is no longer described in
terms of cpus?
Related, "set disassembler-options" should work to clear options.
I couldn't tell whether it works from a quick skim over your
latest patch.
Thanks a lot for working on this, BTW.
