Dear maintainer(s),

Linux 6.19 will drop support for 31-bit compatibility on s390x, and will
also stop providing 31-bit support in UAPI header files [1]. Once this
lands in unstable, it will become impossible to build the libc6-s390 and
libc6-dev-s390 packages on s390x, and in turns the gcc-multilib and
g++-multilib packages.

llvm-toolchain-20 build-depends on g++-multilib [s390x]. Please drop
this build-dependency, likely by stopping the build of s390 binaries.

Please note that this bug will become serious once linux 6.19 reaches
unstable (the upstream release is expected around the beginning of
February).

Regards
Aurelien

Closing bugs reported against llvm-toolchain-20 now that it got removed

This is an automatic notification regarding your Bug report
which was filed against the ftp.debian.org package:

#1116216: RM: llvm-toolchain-20/experimental -- ROM; Won't be in unstable

It has been closed by Debian FTP Masters <ftpmaster@ftp-master.debian.org>.

Their explanation is attached below along with your original report.
If this explanation is unsatisfactory and you have not received a
better one in a separate message then please contact Debian FTP Masters <ftpmaster@ftp-master.debian.org> by

------------------- Reason -------------------
ROM; Won't be in unstable
----------------------------------------------

Note that the package(s) have simply been removed from the tag
database and may (or may not) still be in the pool; this is not a bug.
The package(s) will be physically removed automatically when no suite
references them (and in the case of source, when no binary references
it).  Please also remember that the changes have been done on the
master archive and will not propagate to any mirrors until the next
dinstall run at the earliest.

Packages are usually not removed from testing by hand. Testing tracks
unstable and will automatically remove packages which were removed
from unstable when removing them from testing causes no dependency
problems. The release team can force a removal from testing if it is
really needed, please contact them if this should be the case.

Bugs which have been reported against this package are not automatically
removed from the Bug Tracking System.  Please check all open bugs and
close them or re-assign them to another package if the removed package
was superseded by another one.

The version of this package that was in Debian prior to this removal
can still be found using https://snapshot.debian.org/.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1116216@bugs.debian.org.
