/* 
  Table of instructions. Each instruction
  is defined by the following macro:

	Insn(enumval, gasfmt, p9fmt, uses, defs)

  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.

  The uppercase version of these formats denote the plan 9
  syntax of the above.

  Because 0 indictates the sentiel value, the indexing on use
  and def statments is 1-based.
