7. For both of the instructions shown below, the initial conditions are shown. The result (which the instruction stores in r1) is also shown. For each instruction, answer these questions: • What is the state of the flags (NZCV) after the instruction executes • If the operands were signed, are the results valid? Why or why not? • If the operands were unsigned, are the results valid? Why or why not? a) initial conditions: r0 = 0xAAAA_AAAA rl=0x5555_5555 ADDS rl,rl,ro Result: r1=0xFFFF_FFFF b) initial conditions: r0=0x7FFF_FFFD r1 = 0x0000_000F ADDS rl,ro,r1 Result: r1=0x8000_000C
