#[repr(simd)]
pub struct __m256i(_, _, _, _);
This is supported on x86-64 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 two i8 variables packed togetheri16x16 - sixteen i16 variables packed togetheri32x8 - eight i32 variables packed togetheri64x4 - four i64 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.
