2. Suppose you are given the following program: 1 mul rl r2 r3 2 add r4 r4 rl 3 mul rl r5 r6 4 sub r4 r4 rl Consider the following table which shows the data dependency types for all pairs of instructions from the above program: RAW WAR WAW nst 1 Inst 2 nst 1 Inst 3 nst 1Inst 4 nst 2 Inst 3 Yes No No For example, first row of table means that from instruction in lne 1 to instruction in line 2, there is a RAW dependency but no WAR and WAW dependencies. Fill in the rest of the table (the grayed-out cells)
