Is there a way to have non-blocking breakpoints, where only a callback
is called?

What would be the advantage of simulavr-breakpoints over checking PC
after Step()-ing in single steps in a python script? Better performance
because the inner loop is completely in C++?

In this manual:
I found a chapter on how to read line numbers from COFF. In the ELF
backend chapter, there isn't very much:

My method (Popen avr-gdb) works for me, so I don't have a big need to
extend simulavr right now. But if more users need this feature (get
adress of breakpoint by line) it's maybe worth to implement in simulavr.
