Synopsis
_mm_maskz_fmsub_ps(__mmask8 k, __m128 a, __m128 b, __m128 c);
Description
Multiply packed single-precision (32-bit) floating-point elements in "a" and "b", subtract packed elements in "c" from the intermediate result, 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]) - c[i+31:i]
ELSE
dst[i+31:i] := 0
FI
ENDFOR
dst[MAX:128] := 0
