$ cd emsdk
$ git pull
$ ./emsdk install latest
$ ./emsdk activate latest
$ echo "source /opt/emsdk/emsdk_env.sh" >> "${HOME}"/.bashrc

And then run ./build.sh to build the source code, the folder out will be created and files will be generated under it.

Run ./run_aot.sh to test the benchmark, the native mode and iwasm aot mode will be tested for each workload, and the file report.txt will be generated.
