I haven't. clang 3.9 boot1.efi won't run in the slightest. It crashes prior to me being able to even use printf. I could try a 3.9 loader.efi with some extra printf debugging, though. A clang 3.8 kernel works perfectly when matched with a clang 3.8 boot1.efi and loader.efi. The clang 3.9 kernel doesn't output a single thing. I could probably try some printf based debugging early in the process. But it's clear that loader.efi loads the kernel and tries to execute it.
