If going straight to the end of the recording log is a valuable
feature, I was thinking it may deserve its own command.
Ultimately, I'm hoping that with such a command, we can then see
if we can have PRecord directly jump from recorded execution
to live execution without stopping.
Note that we had a discussion a while ago about adding a general "go to point in
time in recording/reverse execution history" command, which would kind of solve
this as a special case (provided you can find the "last" time). We can already
do this in Simics, but there is no support in the gdb-serial protocol or the gdb
CLI or MI to access the function. The undodb people had the same issue.
