Day 20 of the Advent of Compiler Optimisations - Vectorisation
I think we're ready: it's time to look at how the compiler can get the CPU to do more than one element at a time with vectorisation. SIMD instructions are fantastic speed-ups for some operations and the compiler knows how to use them: if you set it up appropriately.

This series will cover various fun compiler tricks and optimisations I've spotted in my years of playing around with Compiler Explorer. There will be 25 episodes in total, each with an accompanying blog post.
