Would that be useful?
Not very normal but it is a bug that should be fixed so you don't crash and burn. The behaviour should be the same on all archs. Then you could consider adding a build time failure for undef weaks if WD et. all think it is a good idea. I don't see a good reason to ban undef. weaks ATM. One day they might be needed. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
