ntrinsics _mm256_permutexvar_epi64 doesn't accept three parameters as specify bellow. 

I deleted the extra mask parameter.

__m256i _mm256_permutexvar_epi64 (__m256i idx, __m256i a)
#include "immintrin.h"
Instruction: vpermq
CPUID Flags: AVX512VL + AVX512F
Description
Shuffle 64-bit integers in a across lanes using the corresponding index in idx, and store the results in dst.
Operation
FOR j := 0 to 3
  i := j*64
    id := idx[i+1:i]*64
      dst[i+63:i] := a[id+63:id]
      ENDFOR
      dst[MAX:256] := 0
      dst[MAX:256] := 0
