Wenyong Huang 8d88471c46 Implement AOT static PGO (#2243) ... LLVM PGO (Profile-Guided Optimization) allows the compiler to better optimize code for how it actually runs. This PR implements the AOT static PGO, and is tested on Linux x86-64 and x86-32. The basic steps are: 1. Use `wamrc --enable-llvm-pgo -o <aot_file_of_pgo> <wasm_file>` to generate an instrumented aot file. 2. Compile iwasm with `cmake -DWAMR_BUILD_STATIC_PGO=1` and run `iwasm --gen-prof-file=<raw_profile_file> <aot_file_of_pgo>` to generate the raw profile file. 3. Run `llvm-profdata merge -output=<profile_file> <raw_profile_file>` to merge the raw profile file into the profile file. 4. Run `wamrc --use-prof-file=<profile_file> -o <aot_file> <wasm_file>` to generate the optimized aot file. 5. Run the optimized aot_file: `iwasm <aot_file>`. The test scripts are also added for each benchmark, run `test_pgo.sh` under each benchmark's folder to test the AOT static pgo.		2023-06-05 09:17:39 +08:00
