-/* Table of instructions. Each instruction

- Insn(enumval, fmt, attr)
- The format string 'fmt' has the following expansions:
- %r - int reg
- %f - xmm reg
- %m - mem
- %i - imm
- %v - reg/mem
- %u - reg/imm
- %x - reg/freg/mem/imm
- %[1-9]*t - Mode of an operand. The optional number
- preceeding it is the operand desired for
- the mode.
- Currently, there aren't any attrs, because none were needed yet.
- Eventually, they'll probably include flag setting and so on. The
- upper case versions of these indicate Plan9 location formatting.
