Which registers are changed by the cmp instruction?
MP Compares the first source operand with the second source operand and sets the status flags in the EFLAGS register according to the results. The comparison is performed by subtracting the second operand from the first operand and then setting the status flags in the same manner as the SUB instruction. When an immediate value is used as an operand, it is sign-extended to the length of the first operand. So, only the flags are affected. Operation: temp = Source1 - SignExtend(Source2); ModifyStatusFlags(); //Modify status flags in the same manner as the SUB instruction Flags affected: The CF, OF, SF, ZF, AF, and PF flags are set according to the result.
