/* 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.

2 rs2 register.
d rd register.
