Question 1 The REPNZ CMPSB instruction pair will execute as long as the byte pointed to by ESI is not equal to the byte pointed to by ED o True o False Question 2 What instruction is needed so that the following code works properly? mov esi offset dBufferl mov edi offset dBuffer2 mov ecx, LENGTHOF dBufferl add esi, SIZEOF dBufferl TYPE dBufferl point at end of buffer add edi SIZEOF dBuffer2 TYPE dBuffer2 What instruction should go here? rep movsd Question 3 The following code does what? mov esi, OFFSET dSource mov edi, OFFSET dDest mov ecx, LENGTHOF dSource cld repe cmpsd e L1 Compares elements in the dSource array to elements in the dDest array until a equal element is found Compares elements in the dSource array to elements in the dDest array until a non-equal element is found Compares elements in the dSource array to elements in the dDest array until a non-equal element is found or the end of the array is reached Compares a value in EAxto elements in the dDest array until a matching element is found
