Instruction
VSUBPS xmm {z}, xmm, xmm
Synopsis
_mm_maskz_sub_ps(__mmask8 k, __m128 a, __m128 b);
Description
Subtract packed single-precision (32-bit) floating-point elements in "b" from packed single-precision (32-bit) floating-point elements in "a", 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 3
i := j*32
IF k[j]
dst[i+31:i] := a[i+31:i] - b[i+31:i]
ELSE
dst[i+31:i] := 0
FI
ENDFOR
dst[MAX:128] := 0
