Unless you have a real > need for them I would suggest simply dropping this part of the patch. No, I don't have a real need for them.=20 I implemented them as annotations are implemented for the ordinary bt comma= nd.=20 Since "bt shadow" shares a couple of functions I wasn't sure. Partially hav= ing annotations for "bt shadow" seemed wrong, too. Alternatively, I see 2 options: - I could add a check and in case of bt shadow not print annotations at al= l - Remove annotations for the bt command completely I only found this comment in the docs: "The annotation mechanism has largely been superseded by GDB/MI (see GDB/MI= )." https://sourceware.org/gdb/current/onlinedocs/gdb.html/Annotations.html#Ann= otations I am not sure if that means that they are deprecated or just rarely used. B= ut maybe I am missing something. What do you think?
