Subject: [PATCH 0/5] Fix and update LLVM and clang-toolchain.
Date: Fri,  8 Jul 2022 15:57:30 +0000

This patchset updates and fixes the builds of llvm-3.7, llvm-3.8, and
llvm-8 and also updates llvm-14.

The only failing depedent package is beignet, which has failed to build
since last year's replacement of ocl-icd with opencl-icd-loader. beignet
has no dependents and was last updated in 2017.

By building clang-toolchain with a libomp built with the same version of
llvm we remove the additional copy of llvm and reduce the size of the
closure from 1330.9 MB to 1156 MB.

If this is accepted I would look to submit a follow-on patchset adding
libomp varients for clang-toolchain-12 and earlier.
