Synopsis
_mm_fmadd_pd(__m128d a, __m128d b, __m128d c);
Description
Multiply packed double-precision (64-bit) floating-point elements in "a" and "b", add the intermediate result to packed elements in "c", and store the results in "dst".
Operation
FOR j := 0 to 1
i := j*64
dst[i+63:i] := (a[i+63:i] * b[i+63:i]) + c[i+63:i]
ENDFOR
dst[MAX:128] := 0
