Synopsis
_mm512_sll_epi64(__m512i a, __m128i count);
Description
Shift packed 64-bit integers in "a" left by "count" while shifting in zeros, and store the results in "dst".
Operation
FOR j := 0 to 7
i := j*64
IF count[63:0] > 63
dst[i+63:i] := 0
ELSE
dst[i+63:i] := ZeroExtend64(a[i+63:i] << count[63:0])
FI
ENDFOR
dst[MAX:512] := 0
