Synopsis
_mm512_fmsub_pd(__m512d a, __m512d b, __m512d c);
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".
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
