I wish to share a homepage I recently found which is pretty cool. Its a complete online arm simulator, from a man called Henry Wong in Canada, I'm really impressed and the interface is really good. Those who want to learn armv7 assembly language (gnu-as) without setting up anything at all, or just for quick tryouts, tricks, hacks and similar, this is indded a good place to start.
