Gas recognizes all 68k instructions, privileged or non-privileged.

In one sentence: You save your program in a file with suffix .s
(e.g. myprog.s) and assemble it.  See man pages.

On NetBSD?  No, only kernel runs in supervisor mode, and no user
program is allowed to run in supervisor mode.  Besides, this shouldn't
be necessary.  If you absolutely need to use privileged instructions,
you should probably be writing a device driver, instead of a user
program.
