Instruction
VPMOVQD xmm {z}, xmm
Synopsis
_mm_maskz_cvtepi64_epi32(__mmask8 k, __m128i a);
Description
Convert packed 64-bit integers in "a" to packed 32-bit integers with truncation, and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation
FOR j := 0 to 1
i := 64*j
l := 32*j
IF k[j]
dst[l+31:l] := Truncate32(a[i+63:i])
ELSE
dst[l+31:l] := 0
FI
ENDFOR
dst[MAX:64] := 0
