Pre-built LLVM toolchain releases consumed by hew-lang/hew CI and release builds.
This repo exists so that LLVM toolchain artifacts don't clutter hew's own release history. Nothing published here is a Hew language release — it's build infrastructure.
.github/workflows/prebuild-llvm.yml— builds LLVM from source for windows-msvc (Windows lacks a usable upstream prebuilt LLVM tarball for Hew's linker requirements) and publishes it as a versioned GitHub Release asset, verified with a SHA-256 checksum and SLSA build provenance attestation.
Runs weekly and on manual dispatch. hew's .github/actions/setup-llvm
action and release.yml download the published asset directly from this
repo's releases.
