4. Draw the data dependence graph for the following piece of code. Don't forget to label the dependence edges with their latency. R1 = LOAD(A) R2 = LOAD (B) R3 = LOAD (C) R4 = R2 R1 R5 = R4 * R1 R6 = R1 + R2 R7 = R4 + R6 R8 - R5 R6 R10 - R3 * R9 D = STORE (R10) 5. What are the "heights" of the instructions in the DDG? 6. Give a schedule for the program, using height-based list scheduling. If there is a tie in heights, break the tie by scheduling the instruction that is earlier in the program order
