/* All sparc opcodes are 32 bits, except for the `set' instruction (really a
   macro), which is 64 bits. It is handled as a special case.
 
   The match component is a mask saying which bits must match a particular
   opcode in order for an instruction to be an instance of that opcode.
 
   The args component is a string containing one character for each operand of the
   instruction.
 
   Kinds of operands:
	#	Number used by optimizer.	It is ignored.
	1	rs1 register.
	2	rs2 register.
	d	rd register.
	e	frs1 floating point register.
	v	frs1 floating point register (double/even).

	J	frsd floating point register (quad/multiple of 4).
	}       frsd floating point register (double/even) that is == frs2
	b	crs1 coprocessor register
