The author gives a godbolt link. It takes 5 minutes to add two compilers on raptorlake and see that it gives the same result.

So no, Haswell is not the problem. LLVM just doesn't know about the dependency thing.

I have a box that old that can run image diffusion models (I upgraded the GPU during covid.)
My point being that compiler authors do worry about “obsolete” targets because they’re widely used for compatibility reasons.
Since we're using Rust there's some decent syntactic sugar for this function you can use instead:
let cmp = |other: &Neighbor| -> Ordering {
other.dist.partial_cmp(&neighbor.dist).unwrap()
.then_with(|| other.id.cmp(&neighbor.id))
};
