The current situation is that you can build a toolchain with Ada-support using the rsb, it will compile, but the programs it creates will fail at least for arm, but I think the error is architecture agnostic. So you need to find out why it fails, apply a patch like yours locally and rebuild which makes the process quite painful.

Is there a ticket in Trac for 4.11 tracking this issue? We need tickets
for anything destined for 4.11.

I would prefer nothing changes for 4.11.0. This change can then be
reviewed and tested on the 4.11-branch and if ok we can look at 4.11.1.
This is not reflection on the importance of the change, it is a
reflection on me having too many moving parts as I attempt to get 4.11.0
released. My hope is getting 4.11.0 out will smooth the path for future
releases.

I do not see Ada as this. We will support what we can and what is
practical. If members of the community are willing to support Ada, to
test it and to contribute patches then we are willing to accept them. If
are willing to look after Ada, monitor it and test it we would welcome
your efforts.
