In this case I think the code is only using GCC as a sort of glorified
assembler. From what I can see it is not taking the qemu approach of
having GCC compile C, then memcpying around the resulting object code.
Instead it is just using inline assembler, like:
This seems more reliable than the write-it-in-C approach.
