Synopsis
_mm256_fnmsub_ps(__m256 a, __m256 b, __m256 c);
Description
Multiply packed single-precision (32-bit) floating-point elements in "a" and "b", subtract packed elements in "c" from the negated intermediate result, and store the results in "dst".
Operation
FOR j := 0 to 7
i := j*32
dst[i+31:i] := -(a[i+31:i] * b[i+31:i]) - c[i+31:i]
ENDFOR
dst[MAX:256] := 0
