Hi @myhsu
Even though the instruction selection is focused on `sub 0 x` only, I still want to build a simple function with clang and run it with QEMU user emulator (qemu-m68k). But I have no idea how to cross-compile it with GCC runtime, do you have any document for it or could you show me a brief instruction.
