Hi all,

As of, it looks like `ScopInfo/fortran_array_param_nonmalloc_nonvectored.ll` is failing. See for the full test failure. I pinged the author but was notified that the change does not warrant a revert because it is not considered a core-tier project. So a couple of questions:

- Is polly considered a peripheral-tier project?
- If so, what's the policy on getting polly fixes/updates out as a response to upstream LLVM changes?

The tier system was introduced when integrating Bazel into the
monorepo. Although the docs page does not explicitly mention what is
which tier, the discussion around it [1-3] makes it clear that Polly
is a core-tier project that makes it clear that "we should not break
it." It is part of the buildbot and pre-merge check system and
breaking it means people blame mails and pre-merge check failures.

I am working on a patch to repair the test-case.
