Synopsis
_mm256_sub_pd(__m256d a, __m256d b);
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".
Operation
FOR j := 0 to 3
i := j*64
dst[i+63:i] := a[i+63:i] - b[i+63:i]
ENDFOR
dst[MAX:256] := 0
