Hello, I'm silently following rust progress, and thought I chip in here.

LLVM does not have any autovectorization currently. There is a
project called polly that does some of that, but I guess it's a
separate research project that may or may not merge with mainline
llvm if it ever bears fruit.
Personally, I would be pretty happy with types like
simd::float4 made available with the most obvious operators.
Especially if I can wrap it something like
import simd::float4;
import math;
type vec3f = simd::float4;
fn length_squared(v: vec3f) -> float { v[0] * v[0] + v[1] * v[1] + v[2]
* v[2] }
fn length(v: vec3f) -> float { math::sqrt(length_squared(v)); }
fn normalize(v:vec3f) -> vec3f { v / length(v) }
