Compilers: Key Loop Optimization Techniques Explained with Examples

Описание: In this video, we describe *loop optimizations* in compiler design, focusing on five key techniques to enhance program efficiency and performance. With simple C++ examples, we explore how these optimizations work and how they can significantly improve code execution. The techniques explained include Loop unrolling, loop invariant code motion, loop fusion, loop fission, and loop unswitching. You can download example code written in this video from [github](https://github.com/faisal-aslam/compi....
