Hi Franck, Great piece of work. From your earlier email, I prefer the generalized approach, where you add more structure to the basic XML feature. In this case to provide SPR groups. It would be really good to do two things with this. 1) Run it past the GDB mailing list, to see if you get any feedback about why this might not be a good thing. 2) Document it well, so that future users of XML architecture specifications can learn from OpenRISC. This should be both in the user guides and in Doxygen comments in the code.
