Neonfloat64x2_tvmovq_n_f64(float64_t value)Vector manipulation / Set all lanes to the same value
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.
