Assume that x11 is initialized to 11 and x12 is initialized to 22. Suppose you executed the code below on a version of the pipeline that does not handle data hazards (i.e., the programmer is responsible for addressing data hazards by inserting NOP instructions where necessary). What would the final values of register x15 be? Assume the register file is written at the beginning of the cycle and read at the end of a cycle. Therefore, an ID stage will return the results of a WB state occurring during the same cycle.

addi x11, x12, 7

add x13, x11, x12

addi x14, x11, 17

add x15, x11, x11
