9. [3 points] Use the register and memory values in the table below for the next questions. Assume a 32-bit machine. Assume each of the following questions starts from the table values; that is, DO NOT use value changes from one question as propagating into future parts of the question. Register RI R2 R3 R4 Contents Memory Address 12 16 Contents 16 20 24 28 12 16 2420 24 Give the values of R1, R2, and R3 after this instruction: add R3, R2, Ri. What values will be in RI and R3 after this instruction is executed: load R3, 12(R). What values will be in the registers after this instruction is executed: addi R2, R3, #16 b)
