This series buils up on and complements recent work of Thomas Murta, Mark Cave-Ayland and Richard Henderson in the same area. 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.
