Synopsis
 _mm512_fmsub_round_pd(__m512d a, __m512d b, __m512d c, int rounding);
Description
Multiply packed double-precision (64-bit) floating-point elements in "a" and "b", subtract packed elements in "c" from the intermediate result, and store the results in "dst". [round_note]
Operation
FOR j := 0 to 7
	i := j*64
	dst[i+63:i] := (a[i+63:i] * b[i+63:i]) - c[i+63:i]
ENDFOR
dst[MAX:512] := 0
