34 * @brief Tensor registry class for controlflow backend
36 * This class contains three types of tensors. Two native tensors(tensors that are managed by this
37 * backend) and the other is migrant tensor.
39 * - NativeUserTensor - @c UserTensor managed by this backend, buffer is user-given
40 * - NativeOwnTensor - @c cpu_common::Tensor managed by this backend ( in @c _base_reg )
41 * - MigrantTensor - @c IPortableTensor managed by other backends ( in @c _base_reg )
43 * @note @c _base_reg is used in implementation to reuse @c cpu_common::StaticTensorManager
