However, with the evolution of technology, on the one hand, this solution has been replaced by other solutions due to efficiency reasons; on the other hand, ts2abc has also been replaced and offline by es2abc, so the ark_asm tool has not been involved in the application compilation or development process. After the ark_asm tool is offline, developers can find the changes as shown in the figure below in the toolchains directory of the sdk. 12e41f4b71Sopenharmony_ci 13e41f4b71Sopenharmony_ci 14e41f4b71Sopenharmony_ci 15e41f4b71Sopenharmony_ci**Change Impact** 16e41f4b71Sopenharmony_ci 17e41f4b71Sopenharmony_ciThis change is a compatibility change.
