As soon as the hardware device necessary for this becomes available, I will submit some patches to the list. I also know another target that has access to the debug registers but does not have the hardware breakpoint implementation. It would be nice to use its capability of accessing these registers to implement watchpoints. -- Fernando Nasser Red Hat Canada Ltd.
