Neonpoly8x16_tvzip2q_p8(poly8x16_t a, poly8x16_t b)Vector manipulation / Zip elements
Description
Zip vectors (secondary). This instruction reads adjacent vector elements from the upper half of two source SIMD&FP registers as pairs, interleaves the pairs and places them into a vector, and writes the vector to the destination SIMD&FP register. The first pair from the first source register is placed into the two lowest vector elements, with subsequent pairs taken alternately from each source register.
