Synopsis
_mm512_mask_fmsub_ps(__m512 a, __mmask16 k, __m512 b, __m512 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 writemask "k" (elements are copied from "a" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 15
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] := a[i+31:i]
FI
ENDFOR
dst[MAX:512] := 0
