patch (pragmatic hacks are sometimes useful enough to justify their
existence).  This is not an approval though.   I can see the patch
needs at least a few changes, but before reviewing it I'd like to make
sure there is general agreement on this approach.  Someone else is
free to review and approve it of course.]

I haven't heard comments from any other GMs. Does anyone have a problem with adding some kind of printf to tracepoints? Or does anyone have a problem with adding a new kind of command list to breakpoints that is executed on the target? [P.S. If you respond, IWBN to include your thoughts on why.] I'm inclined to go with having some kind of printf in tracepoints for now.

I don't quite understand the "use case" for printf in tracepoints.
