_mm512_shuffle_f32x4
extern __m512 __cdecl _mm512_shuffle_f32x4(__m512 a, __m512 b, const int imm);
Shuffles four float32 elements from a and b, selected by imm, and stores the result.
_mm512_mask_shuffle_f32x4
extern __m512 __cdecl _mm512_mask_shuffle_f32x4(__m512 src, __mmask16 k, __m512 a, __m512 b, const int imm);
Shuffles four float32 elements from a and b, selected by imm, and stores the result using writemask k (elements are copied from src when the corresponding mask bit is not set).
_mm512_maskz_shuffle_f32x4
extern __m512 __cdecl _mm512_maskz_shuffle_f32x4(__mmask16 k, __m512 a, __m512 b, const int imm);
Shuffles four float32 elements from a and b, selected by imm, and stores the result using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
_mm512_shuffle_f64x2
extern __m512d __cdecl _mm512_shuffle_f64x2(__m512d a, __m512d b, const int imm);
