If you have ever had such a bug, you just don't forget :-) I once spent a day on debugging a problem with a 16bit memory-mapped device that turned out to be caused by gcc performing two byte stores instead of one halfword store for every access, so it would indeed be nice to get a warning when a volatile unsigned short * is dereferenced on an ARM arch that doesn't support halfword accesses. cheers, Lennert ------ Want more information?
