 _mm512_sub_round_pd(__m512d a, __m512d b, int rounding);
Description
Subtract packed double-precision (64-bit) floating-point elements in "b" from packed double-precision (64-bit) floating-point elements in "a", 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]
