Hi,

I saw the activity on the bug report yesterday.  It's unfortunate, but if you
want something to progress, you just need to ping it now and then, otherwise
it just gets buried in the volume of emails and patches.  If the patch was sent
in 2016 and hasn't seen any activity since, there's no real change that some
GDB maintainer will pick it up, review it, test it and merge it out of nowhere
(unless they need it themselves).

And indeed, there's isn't a maintainer dedicated to AVR in GDB, so that doesn't
help.

I would like to see this merged, so I'm working on getting at least a bit of the
GDB testsuite running against simavr.  If that works well enough, at least we'll
get some confidence that this change doesn't break some other use case.

Simon
