Hi,
The deb13u3 package failed to build on a bunch of architectures on trixie:
https://buildd.debian.org/status/package.php?p=llvm-toolchain-22&suite=trixie
The ppc64el build failure is an upstream bug that's fixed in newer
versions of LLVM, but for 22 we can just work around it (which Emilio
did successfully for his deb12u1 upload
https://people.debian.org/~pochu/llvm-bookworm.debdiff ).
The i386 invalid build-dep is related to libomp not being built on
trixie (though it was later added to 19 after trixie's release). Emilio
also fixed that in his bookworm upload.
The remaining two architectures (armel, s390x) not getting built are
because of a bug in d/rules; when I switched from using llvm-libunwind1
to libunwind-19, I missed the spot where the list of architectures for
that package is generated for the build-dep.
I've prepared deb13u4 to fix all of those build failures. I've attached
a debdiff between deb13u3 and deb13u4. If it looks good, I'll do a
source-only upload to trixie.
(Emilio, you'll probably want to pull that libunwind fix into bookworm
and possibly bullseye's llvm-toolchain-22.)
Thanks,
Andres

Hi,
The upload referenced by this bug report has been flagged for acceptance into
