This is highly dependent on the target processor for which you are trying
to schedule the loops. For example, If the machine description of the
target processor doesn't have DFA defined for it SMS is not performed at
all. One good example of a loop that would be scheduled in SMS (on a G5
machine for example) is the dot-product loop.
