Purpose:
Shuffle double-precision (64-bit) floating-point elements in "a" within 128-bit lanes using the control in "imm8", and store the results in "dst".
Result:
__m512d
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m512d a = _mm512_setr_pd(1,2,3,4,5,6,7,8);
__m512d r = _mm512_permute_pd(a, 0b10101010);
double out[8];
_mm512_storeu_pd(out, r);
for (int i = 0; i < 8; i++)
printf("%f\n", out[i]);
}Prototypes
