Synopsis
_mm512_mask_sllv_epi16(__m512i src, __mmask32 k, __m512i a, __m512i count);
Description
Shift packed 16-bit integers in "a" left by the amount specified by the corresponding element in "count" while shifting in zeros, and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 31
i := j*16
IF k[j]
IF count[i+15:i] < 16
dst[i+15:i] := ZeroExtend16(a[i+15:i] << count[i+15:i])
ELSE
dst[i+15:i] := 0
FI
ELSE
dst[i+15:i] := src[i+15:i]
FI
ENDFOR
dst[MAX:512] := 0
