Abstract

LLVM is huge, and it's getting bigger with each and every release. Building it together with a project that depends on it (e.g., a programming language) during a CI build stage is not a good option -- building LLVM alone takes hours!

So why not use pre-built packages from the official LLVM download page? Unfortunately, the official Windows binaries only include the LLVM-C.dll, Clang, and some tools -- there are no LLVM headers, C++ libraries, and many essential LLVM tools such as lli.

The llvm-package-windows project builds all major versions of the LLVM and Clang libraries on GitHub Actions for the following matrix:

• Configuration:

  • Debug
  • Release

• Target CPU:

  • IA32 (a.k.a. x86)
  • AMD64 (a.k.a. x86_64)

• C/C++ Runtime:

  • LIBCMT (static)
  • MSVCRT (dynamic)

The resulting LLVM binary packages are uploaded as GitHub Release artifacts. Compiler developers can now thoroughly test their LLVM-dependent projects on GitHub CI or AppVeyor CI simply by downloading and unpacking an archive with the required LLVM prebuilt libraries and tools during the CI installation stage.

Sample

• Jancy uses llvm-package-windows for CI testing on a range of configurations and LLVM versions. See build logs for more details.
