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. V6: Rebased series to the latest qemu code. Excluded all patches that are already accepted. V5: Fixed vpkpx bug and added it back in patch. Fixed graphical distortions on OSX 10.3 and 10.4. Removed conversion of vmrgh and vmrgl instructions to vector operations for further investigation. V4: Addressed Richard's Henderson's suggestions. Removed vpkpx's optimization for further investigation on graphical distortions it caused on OSX 10.2-4 guests. Added opcodes for vector vmrgh(b|h|w) and vmrgl(b|h|w) in tcg. Implemented vector vmrgh and vmrgl instructions for i386. Converted vmrgh and vmrgl instructions to vector operations. V3: Fixed problem during build. V2: Addressed Richard's Henderson's suggestions. Fixed problem during build on patch 2/8. Rebased series to the latest qemu code.
