My fault: I just compiled the instruction with an assembler instead of looking up the actual instruction from documentation. It makes much more sense: resetting ax, and bc (xor ax,ax ; xor bx,bx) will be 4 octets, DWORD aligned, and a bit faster to fetch by the x86 than the 3-octet version I wrote before. |
