[bug#56452] [PATCH 0/5] Fix and update LLVM and clang-toolchain.

[bug#56452] [PATCH 0/5] Fix and update LLVM and clang-toolchain.

[Greg Hogan]

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.

Hi,

It fails to build for me, like so:

Could you take a look?

Yay!

It’s still terrible, but it’s an improvement.

Sounds good.

Applied it all except the faust patch; let me know what to do with that
one.

Thanks!

Ludo',

Thanks for the review! I failed to register that by switching the
dependency from llvm-3.8 to llvm, the faust-2 build would no longer be
initiated when building all dependencies of llvm-3.8.

I have a patch to follow-up with git send-email. I have cc'd Ricardo
since he looks to be both a user and maintainer of the faust packages.
