Add dist step for Enzyme by Kobzol · Pull Request #150071 · rust-lang/rust

Kobzol · 2025-12-16T21:07:52Z

Now that Enzyme can be distributed as a separate dylib outside libLLVM.so, we can create a dist step for it. This is the bulk of the work required to make it distributable through rustup, once CI works and we check that the built component works locally, we can add it to Rustup through the manifest.

Note that this PR does not enable Enzyme distribution in CI yet, it just adds the dist step.

 builder.compiler(target_compiler.stage - 1, builder.config.host_target);

 // Build enzyme
- if builder.config.llvm_enzyme && !builder.config.dry_run() {


ignore if it's just for testing, but the dry_run check was needed as bugfix for something, might have been check builds.

If I don't understand why something is in bootstrap, I usually remove it, then wait if something breaks, and if it does, I readd it back with a comment, so that we know why it is there :)

There's a test which would fail if you hadn't disabled them :P But I can add a note in one of the PRs.

I removed the last commit that enabled building Enzyme on CI, because @ZuseZ4 told me that he wants to make some improvements to Enzyme before that.

ZuseZ4 · 2026-01-20T02:23:01Z

I just confirmed that this can be used to build working artifacts for both linux and macos.
As mentioned, there's still a bit of cleanup left to do, so it's good that we don't enable the artifacts yet.
