'/' starts a comment for some targets. Use .byte instead of .insn with
'/'.

It's interesting that you found a need for this, when I'm sure I made a
comment to this effect during review (somewhere in the series, but
obviously applicable throughout). When approving, you didn't check that
all review comments were addressed, did you?

Nack. The proper approach is to pass --divide to gas for such tests. I've
made very clear during review of the APX series that _wherever possible_
the more descriptive .insn should be used in preference to .byte.
