pub struct __m256i(_, _, _, _);
Available on x86-64 only.
Expand description
256-bit wide integer vector type, x86-specific
This type is the same as the __m256i
type defined by Intel,
representing a 256-bit SIMD register. Usage of this type typically
corresponds to the avx
and up target features for x86/x86_64.
Internally this type may be viewed as:
i8x32
- thirty twoi8
variables packed togetheri16x16
- sixteeni16
variables packed togetheri32x8
- eighti32
variables packed togetheri64x4
- fouri64
variables packed together
(as well as unsigned versions). Each intrinsic may interpret the internal bits differently, check the documentation of the intrinsic to see how it’s being used.
Note that this means that an instance of __m256i
typically just means
a “bag of bits” which is left up to interpretation at the point of use.
Examples
#[cfg(target_arch = "x86")]
use std::arch::x86::*;
#[cfg(target_arch = "x86_64")]
use std::arch::x86_64::*;
let all_bytes_zero = _mm256_setzero_si256();
let all_bytes_one = _mm256_set1_epi8(1);
let eight_i32 = _mm256_set_epi32(1, 2, 3, 4, 5, 6, 7, 8);
