It is based on devising TCG translation implementation for selected instructions rather than using helpers. The selected instructions are most of the time idiosyncratic to ppc platform, so relatively complex TCG translation (without direct mapping to host instruction that is not possible in these cases) seems to be the best option, and that approach is presented in this series. The performance improvements are significant in all cases.
