Instruction
VPCMPD k {k}, xmm, xmm
Synopsis
_mm_mask_cmplt_epi32_mask(__mmask8 k1, __m128i a, __m128i b);
Description
Compare packed signed 32-bit integers in "a" and "b" for less-than, and store the results in mask vector "k" using zeromask "k1" (elements are zeroed out when the corresponding mask bit is not set).
Operation
FOR j := 0 to 3
i := j*32
IF k1[j]
k[j] := ( a[i+31:i] < b[i+31:i] ) ? 1 : 0
ELSE
k[j] := 0
FI
ENDFOR
k[MAX:4] := 0
