Instruction
VPABSQ zmm {z}, zmm
Synopsis
_mm512_maskz_abs_epi64(__mmask8 k, __m512i a);
Description
Compute the absolute value of packed signed 64-bit integers in "a", and store the unsigned 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*64
IF k[j]
dst[i+63:i] := ABS(a[i+63:i])
ELSE
dst[i+63:i] := 0
FI
ENDFOR
dst[MAX:512] := 0
