I have two different versions of "IA-32 Intel Architecture Software Developer's Manual". In Table A-2 "One-byte Opcode Map", one says 0x82 is "Ev, Ib"(the same as 0x83)but the other says 0x82 is "Eb, Ib"(the same as 0x80). But in "instruction set reference", it seems 0x82 is never used(for example, instruction __add__). So, is 0x82 a valid opcode? If it is, how should I decode it?
