Webcmpis typically executed in conjunction with conditional jumps and the setccinstruction. If an operand greater than one byte is compared to an immediate byte, the immediate byte … WebDescription The cmpiinstruction compares the contents of general-purpose register (GPR) RAand a 16- bit signed integer, SI, as signed integers and sets one of the bits in Condition Register Field BF. BFcan be Condition Register Field 0-7; programmers can specify which Condition Register Field will indicate the result of the operation. formal birthday wishes messages
