Building

Please build iwasm and wamrc, refer to:

• Build iwasm on Linux, or Build iwasm on MacOS

• Build wamrc AOT compiler

And install WASI SDK, please download the wasi-sdk release and extract the archive to default path /opt/wasi-sdk.

And then run ./build.sh to build the source code, file coremark.exe, coremark.wasm and coremark.aot will be generated.

Running

Run ./run.sh to test the benchmark, the native mode, iwasm aot mode and iwasm interpreter mode will be tested respectively.

Run ./test_pgo.sh to test the benchmark with AOT static PGO (Profile-Guided Optimization) enabled, please refer here to install tool llvm-profdata and build iwasm with cmake -DWAMR_BUILD_STATIC_PGO=1.

• For Linux, build iwasm with cmake -DWAMR_BUILD_STATIC_PGO=1, then run ./test_pgo.sh to test the benchmark with AOT static PGO (Profile-Guided Optimization) enabled.

• For Linux-sgx, similarly, build iwasm with cmake -DWAMR_BUILD_STATIC_PGO=1, then make in the directory enclave-sample. And run ./test_pgo.sh --sgx to test the benchmark.
