core::arch::x86_64::__m256d - Rust
Description: API documentation for the Rust `__m256d` struct in crate `core`.
Keywords: rust, rustlang, rust-lang, __m256d

# 1.27.0[−][src]Struct core::arch::x86_64::__m256d

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

This is supported on x86-64 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);
