4, [6 points] Use the register and memory values in the table below for this question. 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. a) Give the values of R1, R2, and R3 after this instruction: sub R1, R2, R3 b) What values will be in R1 and R2 after this instruction is executed: lw R2, 8(R1) c) What values will be in R2 and R4 after this instruction is executed: addi R2, R4, 0x0020
