Description
ADDPS
__m128 _mm_add_ps(__m128 a, __m128 b)
Adds the four SP FP values of a and b.
ADDSS
__m128 _mm_add_ss(__m128 a, __m128 b)

floating-point) values of a and b; the upper
three SP FP values are passed through
from a.
ANDPS
__m128 _mm_andnot_ps(__m128 a, __m128 b)Computes the bitwise AND-NOT of the four
SP FP values of a and b.
