I am sort of looking into the concept of running Objective-C in a kernel of an operating system, which would require implementing a (partial) libobjc2 and Foundation that can run on bare metal. Since all my develop machines have clang I can exchange compiled object files in LLVM bitcode and only the linking would ask for a Linux box. This is why I am asking this question.
