Thanks Martin, your changes looks good to me now.

The commenting in register_ppc.hpp could still be improved though. E.g. the comment refers to `v` and `vs` registers but the declared names are `VR` and `VSR`. Probably the declared names should be changed but that's nothing to be done in this pr.

Thanks, Richard.
