Hi Ada coders and lovers,
As x86 (32-bit for i686->) is not primary architecture anymore [2] and we have at least one bug which blocks gprbuild [1] (and as the result almost whole stack) I start to think about dropping i686 from the list of GNAT_arches since F26 onward. Any ideas/objections?

First, did you mean to write "F27"? Because I thought we had a working GPRbuild in F26. Or is it necessary to rebuild it now, right after the release?
Have you reported this to GCC upstream? I don't think a report in Red Hat Bugzilla accomplishes anything more than tracking the bug. A report in GCC Bugzilla should reach some GNAT developers. We might not get a speedy fix for F27 though.
If only GPRbuild triggers the bug, and no fix arrives before the next soname change in libgnat, then we'll probably need to drop x86 from GPRbuild_arches at least temporarily, but we could keep it in GNAT_arches. If it turns out to be so bad that many things can't be compiled on x86, then we may need to drop it from GNAT_arches too.

Hi, our spam filter doesn't like your "antispam email" again... Right. I meant f27. But 26 is affected as well and we cannot rebuild gnatcoll and gprbuild at least in case if it's needed. And I found another problem last week. While GCC changed versioning to major only (libgnat-7 instead of libgnat-7.1) ALI files are marked as obsolete after update to 7.1 in F26/rawhide and I had to rebuild all packages manualy with buildroot overrides and stuff. Ali contains: "GNAT Lib v7" So it should be fine at first glance..

Not yet. I've not reproduced the bug with upstream compiler (without d/s patches). Package mantainer should raise the bug upstream in such cases but seems like it's not the case :(

So far only gprbuild and gnatcoll are affected (as they very connected with low-level gnat I think).

Oh, that's bad!
At the moment I'm not sure how to prevent that from happening again.

An update on this topic:
Now that GCC 8 has arrived in Rawhide, there is no project file support in Gnatmake anymore. In previos releases Gnatmake has been printing warnings stating that support for project files would be dropped, and now it has apparently happened.
Consequently, those Fedora packages that were previously built with Gnatmake have now been rebuilt with GPRbuild. As GPRbuild is still excluded from x86-32, this means that all Ada packages except for the compiler itself are now gone from x86-32.
On the other hand, the compiler bug is supposed to be fixed now. Someone who cares, and has time and a 32-bit Fedora system, could try to re-bootstrap GPRbuild on x86-32.
