Purpose:
Shuffle double-precision (64-bit) floating-point elements in a using the control in c, and store the results in output.
Result:
__m128d
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m128d a = _mm_set_pd(2.0, 1.0);
__m128d r = _mm_permute_pd(a, 0b01);
double *res = (double*)&r;
printf("%f %f\n", res[0], res[1]);
return 0;
}Prototypes

vpermilpd
Usage:
__m128d result =
_mm_permute_pd(
__m128d a, int b
)
