Neonpoly64x2_tvuzp2q_p64(poly64x2_t a, poly64x2_t b)Vector manipulation / Unzip elements
Description
Unzip vectors (secondary). This instruction reads corresponding odd-numbered vector elements from the two source SIMD&FP registers, places the result from the first source register into consecutive elements in the lower half of a vector, and the result from the second source register into consecutive elements in the upper half of a vector, and writes the vector to the destination SIMD&FP register.
