The changes should either be adding some facility to gcc which permits QEMU to use it in this way (gcc is an open source project after all, so it's at least a possibility), or we should generate the dynamic code generator once with whatever version of GCC and make that part of the build, perhaps even letting it diverge (i.e. add enhancements/optimizations directly to the generated assembly). -- John.
