[Bug 1987623] [NEW] RM llvm-toolchain-12 from kinetic

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Simon Chopin (schopin):

This package blocks the glibc 2.36 transition due to breakage of
libsanitizer that isn't observed on later versions of LLVM. Plus, it has
already been removed from Debian testing due to this bug:

* thunderbird                   (for libclang-12-dev)
* thunderbird                   (for clang-12)

In the case of libmkl-* and thunderbird, the dependencies are in OR
clauses with later versions of LLVM, so there shouldn't be any breakage.

pocl is fixed in -proposed, and is waiting on AA resolution of
https://bugs.launchpad.net/ubuntu/+source/pocl/+bug/1987621

nvidia-cuda-toolkit has clang-12 as part of a g++-11 | clang-12 | g++-10
| clang-11 | ... clause, with g++-11 the preferred dependency

Finally, I propose to remove src:opencl-clang-12 and src:spirv-llvm-
translator-12, seeing as:

❯ reverse-depends -a source src:opencl-clang-12
No reverse dependencies found

❯ reverse-depends src:opencl-clang-12         
No reverse dependencies found

❯ reverse-depends -a source src:spirv-llvm-translator-12
Reverse-Build-Depends
* opencl-clang-12               (for libllvmspirvlib-12-dev)

❯ reverse-depends src:spirv-llvm-translator-12       
Reverse-Depends
* libopencl-clang12             (for libllvmspirvlib12)
