Struct core::arch::x86::__m256i 1.27.0[−][src]
#[repr(simd)]pub struct __m256i(_, _, _, _);
This is supported on x86 only.
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 twoi8variables packed togetheri16x16- sixteeni16variables packed togetheri32x8- eighti32variables packed togetheri64x4- fouri64variables 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.
