Purpose:

Bitswap.

Reverse bits in each byte of 32-bit value in register $rs, placing the resultin

register $rt.

Availability:

Assembly alias, not available in NMS

Expansion:

ROTX rt, rs, 7, 8, 1

The assembly alias BITSWAP is provided for compatibility with MIPS32™.Its behavior is equivalent to the new assembly alias BITREVB, whose name is chosen to fit consistently with the naming of other

reversing instructions in nanoMIPS™.
