Assume the following register and memory contents in an IA-32 computer: Register EBX contains 1000. Register ESI contains 2. The numbers 1, 2, 3, 4, 5, and 6, are stored in successive doubleword locations starting at memory address 1000. The address label LOC represents address 1008. What is the effect of executing each of the following three short instruction blocks, starting each time from the given initial values?
