           Summary: Missing _mm256_permutexvar_epi64() intrinsic for
                    AVX512VL
           Product: gcc
           Version: 7.3.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

  Target Milestone: ---

Hi,

The _mm256_permutexvar_epi64() intrinsic is missing from the avx512vlintrin.h
header file. There's only a _mm256_mask_permutexvar_epi64() and a
_mm256_maskz_permutexvar_epi64() variant. Both clang 5.0.x and icc 18.0.x have
this intrinsic in the header.

Thanks,
Carsten
