This repository builds a custom LLVM distribution that comes with statically linked tools (clang, lld, llvm-ar, llvm-as, llvm-nm, llvm-objcopy). This is the minimum set needed to use the outputs as a Bazel cc toolchain with https://github.com/grailbio/bazel-toolchain.

On Linux, we link against musl libc.

On OSX, fully statically linked executable is impossible. We dynamically link only libSystem.

The easiest way to consume this is to check the releases page for pre-built artifacts.

You can also compile from source as follows:

1. Install Bazelisk
2. (Optional, but highly recommended). Setup remote execution by making a free account with Buildbuddy. Add the following to your .bazelrc or ~/.bazelrc: build --remote_header=x-buildbuddy-api-key=YOUR_KEY_HERE
3. Build for your platform: bazel build //:dist

You can also cross-compile for a different platform:

• bazel build //:for_darwin_amd64
• bazel build //:for_darwin_arm64
• bazel build //:for_linux_arm64_musl
• bazel build //:for_linux_amd64_musl
• bazel build //:for_all_platforms (builds all of the above)

This satifies my current needs, but I'm happy to tag additional releases as LLVM upstream releases them. I will probably add additional binaries that are used in Bazel as I need them: llvm-cov, llvm-dwp, llvm-objdump, llvm-profdata. I'm also open to adding extra pre-built artifacts with a more full set of tools (flang, clang-format, etc.) if there is interest.
