5; Use llvm-objdump to check wheter the encodings of microMIPS atomic instructions are correct.
6; While emitting assembly files directly when in microMIPS mode, it is possible to emit a mips32r2
7; instruction instead of microMIPS instruction, and since many mips32r2 and microMIPS
8; instructions have identical assembly formats, invalid instruction cannot be detected.
