//! SIMD vectors.
//!
//! These types can be used for accessing basic SIMD operations. Each of them
//! implements the standard arithmetic operator traits (Add, Sub, Mul, Div,
//! Rem, Shl, Shr) through compiler magic, rather than explicitly. Currently
//! comparison operators are not implemented. To use SSE3+, you must enable
//! the features, like `-C target-feature=sse3,sse4.1,sse4.2`, or a more
//! specific `target-cpu`. No other SIMD intrinsics or high-level wrappers are
//! provided beyond this module.
//!
//! ```rust
//! # #![feature(core)]
//! fn main() {
//!     use std::simd::f32x4;
//!     let a = f32x4(40.0, 41.0, 42.0, 43.0);
//!     let b = f32x4(1.0, 1.1, 3.4, 9.8);
//!     println!("{:?}", a + b);
//! }
//! ```
//!
//! # Stability Note
//!
//! These are all experimental. The interface may change entirely, without
//! warning.
