- Post-multiplication maps each statement instance
to its new position in the transformed loop's
execution sequence.
- gives the new dependence distance
vector, and allows testing for validity.
- This captures skewing, interchange and reversal.
- We can compose transformations by matrix multiplication .
- Working out the resulting loop's bounds is a little tricky.
