Synopsis
_mm512_fnmadd_ps(__m512 a, __m512 b, __m512 c);
Description
Multiply packed single-precision (32-bit) floating-point elements in "a" and "b", add the negated intermediate result to packed elements in "c", and store the results in "dst".
Operation
FOR j := 0 to 15
i := j*32
dst[i+31:i] := -(a[i+31:i] * b[i+31:i]) + c[i+31:i]
ENDFOR
dst[MAX:512] := 0
