VPSLLVD xmm, xmm, xmm
Synopsis
_mm_sllv_epi32(__m128i a, __m128i count);
Description
Shift packed 32-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".
Operation
FOR j := 0 to 3
i := j*32
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
ENDFOR
dst[MAX:128] := 0
