> It seems like rust bundles it's own version of llvm. Are patches from the rust community making it in slowly? Or are there some fundamental differences?
The delta is minimal, and mostly consists in bugfixes and optimizations. All changes are typically forwarded upstream. Since long time, rustc can be built without using the embedded LLVM, and several distributions (eg. Debian) do that.
