It looks likeyou want to make older versions of GDB work with newer versions of thePython scripts in the data directory. I am not sure this is what we want. If you want multiple version of GDB in parallel on a system, they should allbe compiled with a different --prefix, and they will all get their own data-directory. We should only expect a certain version of the datadirectory to be compatible with the version of GDB it was shipped with. Oram I missing some use case where this is not true?Hi,Practically the data-directory is mostly backwards-compatible, except this small part which I found (there might be others which I didn't find). With thispatch, I'm able to run GDB 7.8 with the latest data-directory. Is there a reason not to accept it?
I'd like to know what other maintainers think about this. We may have already faced this situation before and taken a decision which I'm not aware of. Otherwise, we need to take it now.
