PADDSB - Packed ADD signed Saturation Byte

PADDSB xmm1, xmm2/m128    (S2
__m128i _mm_adds_epi8(__m128i a, __m128i b)

For each BYTE, calculate (1) + (2) with signed saturation and set the result to (3). Set -128 / 127 on overflow.
VPADDSB xmm1, xmm2, xmm3/m128    (V1
__m128i _mm_adds_epi8(__m128i a, __m128i b)
VPADDSB xmm1{k1}{z}, xmm2, xmm3/m128    (V5+BW+VL

__m128i _mm_maskz_adds_epi8(__mmask16 k, __m128i a, __m128i b)

For each BYTE, calculate (1) + (2) with signed saturation and set the result to (3). Set -128 / 127 on overflow.
