The user has no reason to be meddling with those (unless he/she is debugging a debugger, but he/she could still check the values that are loaded there while they are still in GPS registers). I think we should consider these debug registers as some piece of debugger hardware similar to one of those JTAG devices, a kind of CPU-embeded logic analyzer or something of a sort -- some debugger device that GDB uses, not as an inferior resource. -- Fernando Nasser Red Hat Canada Ltd.
