/* Table of instructions. Each instruction
is defined by the following macro:
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.
For technical reasons, the indexing on use and def statments is 1-based,
instead of 0-based. (0 is the sentinel value).
