Loop Optimization

Why need to know more about Loop optimization.

Loop optimization is not only a technique used by modern compiler for optimization, but also a technique to get information about the code dependence and how to extract the parallelism for the dependence. Such technique is an interesting topic not only for the compiler developer, but also for every guys who want to use a formal method to know more about his code, and how to make the code run parallelly on CPU/Multi-core/DSP/GUP/Accelerators, etc.
