For what it's worth, I can think of reasons why I might want to use
reverse execution--see my earlier message.
I have no idea why I would ever want to use tracepoints. As far as I
can see, anything I can do with a tracepoint I can do by logging data
in my program--and if I add the logging code to the program, the code
is ready and waiting for the next time I have a problem. There is
probably some cool use for which tracepoints are the obvious right
answer, but I don't know what it is.
