FWIW, there is one big blocker at the moment for using LLVM natively on Linux/m68k which is that the natural alignment of 16 bits of m68k on Linux is incompatible with LLVM [1]. This is something we haven't been able to resolve yet, so if anyone from the NetBSD side has a clever idea, that would be great.
