Source code transformations and optimizations

Describes relevant code transformations and optimizations, and how they can be used in real-life codes. We include descriptions of the various high-level code transformations and their main benefits and goals. We emphasize on the use of loop and function-based transformations for performance improvement using several illustrative examples. We include code specialization as one of the most important sources of performance improvements. In addition, the chapter describes some of the most representative transformations regarding data structures. Our goal in this chapter is to provide a comprehensive catalog of code transformations and to serve as a reference for readers and developers needing to know and apply code transformations. Finally, we include a set of LARA strategies to exemplify possible uses of LARA regarding the main topics of this chapter.
