I don't know exactly how to go about doing that, but yes we should be testing this.  I'll talk to Jim, unless you know how to go about doing this.  Keep in mind emitting a .s file isn't sufficient.  I need to actually emit an object file and then disassemble it to make sure everything is being encoded correctly.
