/* Table of instructions. Each instruction
is defined by the following macro:
Insn(enumval, fmt, attr)
The format string 'fmt' has the following expansions:
%r - A register
%m - A memory location.
%l - A location (either register or memory)
%x - Any value.
%[0-9]*t - Mode of an operand. The optional number
preceeding it is the operand desired for
the mode.
%v - a value (ie, immediate integer or label)
