Struct core::arch::x86::__m256d 1.27.0[−][src]
#[repr(simd)]pub struct __m256d(_, _, _, _);
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);Run
