Struct core::arch::x86::__m256d

#[repr(simd)]
pub struct __m256d(_, _, _, _);

🔬 This is a nightly-only experimental API. (stdsimd #48556)

This is supported on x86 only.

256-bit wide set of four f64 types, x86-specific

This type is the same as the __m256d type defined by Intel, representing a 256-bit SIMD register which internally is consisted of four packed f64 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 __m256d type has one interpretation. Each instance of __m256d always corresponds to f64x4, or four f64 types packed together.

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

Examples

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

let four_zeros = _mm256_setzero_pd();
let four_ones = _mm256_set1_pd(1.0);
let four_floats = _mm256_set_pd(1.0, 2.0, 3.0, 4.0);
