In the previous post we talked about loop unswitching: a technique that the compilers use to make loops faster. Loop unswitching consists of detecting conditional statements whose condition never changes during the execution of the loop (loop invariant conditions) and then moving the condition outside of the loop. Loop unswitching opens the door for other […]

Flexibility and performance: introduction to loop unswitching
Flexibility is very important in the development of software. A great deal of research and education is invested into creating flexible software. However, flexibility and performance don’t often come hand in hand, as most developers have already witnessed sometime in their careers. One of the ways to achieve flexibility is to parametrize the behavior of […]
