Synopsis
_mm256_maskz_srlv_epi32(__mmask8 k, __m256i a, __m256i count);
Description
Shift packed 32-bit integers in "a" right by the amount specified by the corresponding element in "count" while shifting in zeros, and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation
FOR j := 0 to 7
i := j*32
IF k[j]
IF count[i+31:i] < 32
dst[i+31:i] := ZeroExtend32(a[i+31:i] >> count[i+31:i])
ELSE
dst[i+31:i] := 0
FI
ELSE
dst[i+31:i] := 0
FI
ENDFOR
dst[MAX:256] := 0
