5.1.8 String Instructions

Unimplemented instructions: SCAS and LODS variations. Note: the SDM includes the REP(E/NE/Z/ZE) prefixes in this section, but since these are prefixes rather than standalone instructions I can't automatically check whether they're supported. It looks like they are for MOVS/CMPS/STOS.

Unimplemented Instructions

AC	LODS/B
AD	LODS/W/D/Q
