Of note: The reason I was attempting to use target function on a const was because the const needed a different value on different targets. For AVX2 targets, it needed a value of 7, for AVX512 targets, a value of 15, and for other targets, a value of 3. Pointers on how to do it right are appreciated.

EDIT: Of note, I am now aware I did it wrong, and was misunderstanding how it's ment to be used.
