...g file for qemu/kvm with virtio devices (I also think it will work with the default devices). The build process uses llvm-gcc -> opt -> llc so you can add your own (per-file) passes to the build process or debug specific passes. Directories arch/x86/boot and arch/x86/boot/compressed specify NOLLVM in their makefile which causes the make system to use gcc to build the directory. options to opt are controlled by OPT_OPTIONS in the top level makefile.
