What are all the possible resulting values of w, x, y, and z? For each possible outcome, explain how we might arrive at those values. You will need to examine all possible inter leavings of instructions.

Consider the following portions of two different programs running at the same time on four processors in a symmetric multi-core processor (SMP). Assume that before this code is run, both x and y are 0.
