WAMR test benchmarks

This folder contains test benchmarks for wamr.

Build and Run

Refer to the README.md under each folder for how to build and run the benchmark.

Install llvm-profdata

PS: the llvm-profdata vesion needs to be the same major version with llvm libraries used to build wamrc.

The tool llvm-profdata is used when running the test_pgo.sh script under the benchmark folder. There are two ways to install it:

  1. Refer to https://apt.llvm.org/, e.g. in Ubuntu 20.04, add lines below to /etc/apt/source.list
deb http://apt.llvm.org/focal/ llvm-toolchain-focal main
deb-src http://apt.llvm.org/focal/ llvm-toolchain-focal main
# 15
deb http://apt.llvm.org/focal/ llvm-toolchain-focal-15 main
deb-src http://apt.llvm.org/focal/ llvm-toolchain-focal-15 main
# 18
deb http://apt.llvm.org/focal/ llvm-toolchain-focal-18 main
deb-src http://apt.llvm.org/focal/ llvm-toolchain-focal-18 main

Then run sudo apt update, sudo apt install llvm. And after installing:

cd /usr/bin
sudo ln -s llvm-profdata-18 llvm-profdata
  1. Build manually
git clone --depth 1 --branch release/18.x https://github.com/llvm/llvm-project.git
cd llvm-project
