GNAT Ada 2005 targeted to some ARM Linux/VxWorks hosted on x86 would be just fine. Still having target and host of same architecture is a great advantage. If Intel and/or AMD took embedded/mobile seriously, and it seems that they are slowly waking up, they could easily trump ARM. -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
