Neonfloat16x4_tvget_low_f16(float16x8_t a)Vector manipulation / Split vectors
Description
Duplicate vector element to vector or scalar. This instruction duplicates the vector element at the specified element index in the source SIMD&FP register into a scalar or each element in a vector, and writes the result to the destination SIMD&FP register.
