| # 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. |
