Remill Workshop

Setting up the environment

This repository uses a devcontainer.json file to allow you to quickly get started.

1) GitHub Codespaces

Using Codespaces is required for the workshop

1. Login to your GitHub account
2. Fork this repository
3. Click the green <> Code button
4. Press ... and then New with options...
5. Change Machine type to 4-core
6. Then Create codespace
7. Wait a ~3 minutes while the image is loading ☕
   • Press Show log to see progress

Remember to shut down your codespace here when you're finished.

I recommend switching to the GitHub Dark theme, because the LLVM IR syntax highlighting works better there. When prompted by the CMake tools, just close the notifications:

_{At a later date you can set things up locally with Docker Desktop}

Docker Desktop (tricky)

• Install/Update Docker Desktop (alternatives)
• Start Docker Desktop
• Install Visual Studio Code
• Clone and open this repository in VS Code (use the HTTPS protocol)
• Install the Dev Containers extension in VS Code (you should be prompted for recommended extensions)
• Click the blue 'Reopen in Container' button when prompted (you can also find it in the command palette)

For more detailed steps, check out the Dev Containers tutorial. The instructions after this assume you are running inside the container.

Windows

Because the host filesystem is mounted inside the container you may need to configure Git to not automatically convert line endings:

git config --global core.autocrlf false

Additionally it's recommended to configure Docker to use the WSL 2 backend.

2) Building the examples

To build the project, press the Build button in the status bar:

You will be prompted for a preset, select clang and the build will start:

Alternatively you can build with the following commands:

cmake --preset clang
cmake --build build

3) Checking the environment

To verify if the environment is set up correctly, run:

llvm-config --prefix

Expected output:

/cxx-common/install

The ${workspaceFolder}/build directory will also be added to your PATH, so you can easily access your tools from anywhere. To verify, run the following command:

remill-lift --version

Expected output:

remill-lift version v4.1.0-160-g7f091d4
