Somehow I doubt 25,000 lines, unless most of it was comments documenting the architecture and algorithm thoroughly. However, it is certainly true that many of the architectural features being used on today's processors to speed things up are hard to exploit efficiently in a code generator, yet not exploiting them would pretty much defeat their purpose..
