One thing that I was thinking it'd be nice to see about getting
into 8.1 was the DWARF5 index stuff (standard replacement for 
.gdb_index):

 https://sourceware.org/ml/gdb-patches/2017-05/msg00577.html

Not sure about making that the default (seems risky), but it
might be nice to provide the option so that users/distros can
start experimenting (and so that Fedora/RHEL doesn't end up
having to backport yet another large series... :-P) .  I tried
to review that in the past but stumbled  on choices I didn't quite
understand, and there are also some open questions, but I was
planning on taking another look.  I can't really promise I/we can
get it done this week, so not sure about blocking the branching
because of it.

Thanks,
Pedro Alves
