r300 and r600 didn't share much if any code when they were classic Mesa drivers. > Any thoughts about backwards compatibility - old loader (libGL, libEGL etc.) > and new r300_dri?

Xorg has a loader as well, so I think there's no sane way around keeping the existing names as links. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
