How is basic loop unrolling is "not even close" to the expected result when you explicitly ask for optimization with O3?

This isn’t basic loop unrolling; it’s replacing an entire loop with a closed form mathematical formula.

It's a form of loop unrolling. Regardless of the term, this is still very much in the ballpark of what you'd expect when asking for optimization.
