Expand description
256-bit wide set of eight f32 types, x86-specific
This type is the same as the __m256 type defined by Intel,
representing a 256-bit SIMD register which internally is consisted of
eight packed f32 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 __m256 type has one interpretation. Each instance
of __m256 always corresponds to f32x8, or eight f32 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 al
