 * All Sparc instructions are 32-bits, with the one exception being

 *
 * There are 5 different fields that can be used to identify which

 * formats for instuctions, which one being used is determined by
 * bits 30-31 of the insn. Here are the bit fields and their names:
 *

 * 0000 0001 1100 0000 0000 0000 0000 0000 op2 field, format 2 only

Codes:
        1 -- source register operand stored in rs1
	2 -- source register operand stored in rs2
	d -- destination register operand stored in rd
	3 -- floating source register in rs1
	4 -- floating source register in rs2
	e -- floating destination register in rd
	i -- 13-bit immediate value stored in simm13
	j -- 11-bit immediate value stored in simm11
	l -- displacement using d16lo and d16hi
	m -- 22-bit fcc displacement value
	n -- 30-bit displacement used in call insns
	o -- %fcc number specified in cc1 and cc0 fields
	p -- address computed by the contents of rs1+rs2
	q -- address computed by the contents of rs1+simm13
	r -- prefetch
	s -- %asi is implicit in the insn, rs1 value not used
	t -- immediate 8-bit asi value
	u -- 19-bit fcc displacement value
	5 -- hard register, %fsr lower-half
	6 -- hard register, %fsr all
	7 -- [reg_addr rs1+rs2] imm_asi
	8 -- [reg_addr rs1+simm13] %asi
	9 -- logical or of the cmask and mmask fields (membar insn)
	0 -- icc or xcc condition codes register
