@lhames  The other possibility is to lift JIT runtime to top level in llvm-project so it can link libunwind into its runtime so you don't need to:

- Create a public API in libunwind to support JIT
- Worry about deploying a compatible libunwind together with JIT (or worry about back-deploy)
- You can write all the tests in ORCJIT context.
