I must admit I have not read up on the embedded trace capability,
much, but one of the things that I've heard it can do is to
set a breakpoint and then capture the PC for N instructions
going forward.

The trick is how to present that in a GUI....

Could we modify the GDB server to be able to "stepi" through the
trace buffer memory?

The stepping could happen backwards/forwards, while the target
is running continuously.

Getting full stack traces might be but perhaps this is better than
no GUI at all?
