    A good trick which the help output doesn't mention is that % and $ are
    special in input, so you can do:

    0:mon> di %pc

    disassemble instructions at address pointed to by register PC

    Other regs are eg: %lr, %r1, %r12.
    And it works with di, d and other commands.

    Also:

    0:mon> di $.xmon_register_spus

    disassemble instructions at address of symbol .xmon_register_spus.

    cheers
