OK; let's see what happens with the FSF assignment process.

It seems indeed desirable for us to include it in GDB 13, but I don't
think it will be blocking us if the patch gets delayed because
we're waiting for the assignment to come through (looking at progress
on the other issues, I think the FSF still has time). Worst case
scenario, if everything but this patch is done, we can start by
branching and creating our first pre-release. I think it'll be
relatively easy and safe to backport once the patch is approved.

Just for the avoidance of doubt, I assume you guys are finalizing
the patch in parallel to waiting for the FSF to get back to us,
right? Ideally, as soon as we have the paperwork done, the patch
gets pushed.

Thank you,
