The device code is embedded inside the objects so `llvm-nm` won't show the interesting symbols, but we could probably tell by name. The functions listed in the `Supported Functions` header is intended to be an inclusive list. Implementing `malloc` and `free` will require an RPC mechanism to call the host OS from the GPU which we're still working on. I could make this more clear in the current documentation.
