I haved planned to port Alpha and PowerPC to tgc, but got no time / running reference hardware to do it properly at this time. I suppose I would start with Alpha, which is a very simple target, as a training before starting porting PowerPC. And before starting working on PowerPC, I have to isolate and fix various regressions that have been committed during the last monthes (but still I need to have my PowerPC references platforms running to be able to validate the fixes). Talking about Alpha, I would greatly like someone who actually has knowledge of this platform to go on developping it, as I got no hardware to compare with and validate the emulation. If anyone feels like working on it, at least try to compare Qemu behavior with actual hardware and report bugs.... Regards. -- J. Mayer Never organized
