# One line per instruction format family. Each line consists of a
# series of instruction formats that all take (potentially) compatible
# arguments. The order is the preferred order (most to least
# preferable) of formats, when more than one opcode could be used for
# a given instruction's arguments.
#
# Note: The family that starts with 12x has a mix of both two- and
# three- register formats. This is because some of the two-register
# opcodes effectively take three, with a destination and two sources
# where the destination and one of the sources have to be the same.
