Struct __m512d

#[repr(simd)]
pub struct __m512d([f64; 8]);

Available on x86 or x86-64 only.

512-bit wide set of eight f64 types, x86-specific

This type is the same as the __m512d type defined by Intel, representing a 512-bit SIMD register which internally is consisted of eight packed f64 instances. Usage of this type typically corresponds to the avx and up target features for x86/x86_64.

Note that unlike __m512i, the integer version of the 512-bit registers, this __m512d type has one interpretation. Each instance of __m512d always corresponds to f64x8, or eight f64 types packed together.

The in-memory representation of this type is the same as the one of an equivalent array (i.e. the in-memory order of elements is the same, and there is no padding between two consecutive elements); however, the alignment is different and equal to the size of the type. Note that the ABI for function calls may not be the same.

Most intrinsics using __m512d are prefixed with _mm512_ and are suffixed with “pd” (or otherwise contain “pd”). Not to be confused with “ps” which is used for __m512.

Implementations

impl __m512d

fn splat(value: f64) -> __m512d

Using my_simd([x; N]) seemingly fails tests, so use this internal helper for it instead.

const fn as_array(&self) -> &[f64; 8]

Returns an array reference containing the entire SIMD vector.

fn as_mut_array(&mut self) -> &mut [f64; 8]

Returns a mutable array reference containing the entire SIMD vector.

impl __m512d

pub(crate) fn as_f64x8(self) -> f64x8
