VPSLLVQ xmm, xmm, xmm
Synopsis
_mm_sllv_epi64(__m128i a, __m128i count);
Description
Shift packed 64-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 1
i := j*64
IF count[i+63:i] < 64
dst[i+63:i] := ZeroExtend64(a[i+63:i] << count[i+63:i])
ELSE
dst[i+63:i] := 0
FI
ENDFOR
dst[MAX:128] := 0
