Loop Optimizations in compilers[Part 1]

Introduction Loops are “the” most compute intensive part of any software program making loop optimizations some of the most rewarding optimizations for a compiler. In this post, I’ll try to go over some of these optimizations which are covered by LLVM(I’m sure you’ll find them in other compilers too). This is not an extensive list you can always find more. Loop Invariant Code Motion (Code hoisting) It’s a known coding practice to always keep definitions and constant code outside the loop....
