Attached is the diagram of RISC-V pipeline with equality testing being moved to ID stage to optimize branch hazard. Show the number of stalls for the following two cases. 1. sub x10, x11, x12 beq x10, x15, LABEL 2. lw x5, 32(x6) beq x10, x5, LABEL Modify the above diagram to add necessary forward lines to handle these two cases.
