Expand description

256-bit wide set of eight `f32` types, x86-specific

This type is the same as the `__m256` type defined by Intel, representing a 256-bit SIMD register which internally is consisted of eight packed `f32` instances. Usage of this type typically corresponds to the `avx` and up target features for x86/x86_64.

Note that unlike `__m256i`, the integer version of the 256-bit registers, this `__m256` type has one interpretation. Each instance of `__m256` always corresponds to `f32x8`, or eight `f32` types packed together.

Most intrinsics using `__m256` are prefixed with `_mm256_` and are suffixed with “ps” (or otherwise contain “ps”). Not to be confused with “pd” which is used for `__m256d`.

## §Examples

    #[cfg(target_arch = "x86")]
    use std::arch::x86::*;
    #[cfg(target_arch = "x86_64")]
    use std::arch::x86_64::*;

    let eight_zeros = _mm256_setzero_ps();
    let eight_ones = _mm256_set1_ps(1.0);
    let eight_floats = _mm256_set_ps(1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0);
