Consider the following sequence of instructions.

addi x$11,$ x$12,5$

add x$12,$ x$11,$ x$14$

ld x$14,32($x$11)$

add x$12,$ x$14,$ x$11$

How many WAW dependence are there in the above code?

Note: Dependence has a different inpretation than hazards. A dependence condition arises when two instructions are dependent on one another in the use of their register operands. A hazard, on the other hand, is a condition that may result in error when executing dependent instructions.
