    rpminspect: disable abidiff inspection

    We need to disable abidiff due to huge memory consumption, leading to
    OOM kill of the whole rpminspect run.

    Fix alternatives handling

    This implements multiple fixes to the handling of llvm-config
    alternatives:

     * Increase alternative priority for new versions. Otherwise we'll
       give all versions the same priority. The new one will be something
       like 2064 for the 64-bit LLVM 20 llvm-config binary.
     * Remove old llvm-config-64/llvm-config-32 alternative. This is
       only needed once, so suppress the error.
     * Do not remove no longer used llvm-config-64/32 in postun scriptlet.
       Instead remove the llvm-config in install_bindir. However, now
       that the path will be the same for compat and non-compat LLVM,
       only do this on uninstall, not on upgrade.

    Use libdir suffix in versioned prefix as well

    Use the lib/lib64 distinction for the versioned prefix, to avoid
    a mismatch with the default prefix. This means that the versioned
    prefix now has libraries in /usr/lib64/llvmN/lib64.

    This should fix the issue https://src.fedoraproject.org/rpms/llvm/pull-request/446
    ran into. This would also be needed if we wanted to switch to
    installing into libexec.

    Add task-taskwait-nested test to LIT_XFAIL on ppc

    This test fails on ppc, so add it to the XFAIL list like the other
    similar tests. It would be better to fix the root cause, but in the
    meantime, add it to XFAIL to unblock the snapshot builds.

    Invert symlink direction

    This is an alternative to:
    https://src.fedoraproject.org/rpms/llvm/pull-request/439.

    Instead of undoing the prefix change completely, this instead inverts
    the direction of the symlinks: The non-compat package ships all the
    files in the default prefix, but has symlinks from the versioned
    prefix to the default prefix.

    The implementation approach is to install everything into the
    versioned prefix first (keeping things unified between compat and
    non-compat build initially) and to then move and symlink in
    post-processing.

    The llvm-config setup here stays the same as it currently is,
    with llvm-config executables being installed in the versioned
    prefix, while the one in the default prefix is managed by
    alternatives. This patch does not fix the issues with alternatives
    handling, we'd apply https://src.fedoraproject.org/rpms/llvm/pull-request/417
    on top of this patch for that.

    Fixes https://bugzilla.redhat.com/show_bug.cgi?id=2365079.

    llvm-test rather than the main llvm package.

    Add a BuildRequires on llvm when building with pgo

    PGO builds require llvm-profdata which is provided by the llvm package.
    Previously, the build used to pass because llvm-test-suite requires
    llvm. As we restrict the execution of the perf comparison on snapshot
    builds, llvm-test-suite won't be installed anymore.

    Allow openmp tests to re-run two times

    Once https://github.com/llvm/llvm-project/pull/141851 is merged, we can
    use the new lit-option `--max-retries-per-test=<POSTIVE_INT>` in order to
    re-run openmp tests.

    This change makes use of this option and configures it, so that openmp
    tests are re-run 4 times if needed. To prove that this works, we no
    longer filter out the flaky tests.

    Once https://github.com/llvm/llvm-project/pull/142413 lands we can add
    `--show-attempts-count` to show how many attempts were actually needed.

    Bring in PGO (Profile Guided Optimization)

    This enable PGO (Profile Guided Optimization) on Fedora >=41 and RHEL >= 9 for
    non x86 machines.

    This is a four step process:

    1. We use the system clang compiler to build an instrumented version of LLVM.
       The first build of LLVM is rather small because it only features the native
       subset of targets to build (`LLVM_TARGETS_TO_BUILD=Native`) and no tests or
       whatsoever is built.
    2. We run a special `cmake` target (`generate-profdata`) that collects profile
       data information. Eventually this information is also packaged as
       `llvm-pgo.profdata`.
    3. We feed the profile information into another final build of LLVM that gets
       packaged later.
    4. If we are on a platform that provides the `llvm-test-suite` package we run a
       performance comparison of the system compiler against the PGOed compiler.
       This is meant as a sanity check. We package the output of that comparison (if
       available) as `results-system-vs-pgo.txt`. The criteria to run this
       performance comparison is influenced by the `run_pgo_perf_comparison` global.
       For snapshot builds we even run the comparison for RHEL platforms where
       usually the `llvm-test-suite` is not available. There we provide it through
       this COPR project:
       [@fedora-llvm-team/llvm-test-suite](https://copr.fedorainfracloud.org/coprs/g/fedora-llvm-team/llvm-test-suite/).

    We pass `--build-id=sha1` to lld when building final stage with PGO LLD uses
    "fast" as the algortithm for generating build-id values while ld.bfd uses "sha1"
    by default. We need to get lld to use the same algorithm or otherwise we end up
    with errors like thise one:

    ```
    build-id found in [...]/usr/lib64/llvm21/bin/llvm-debuginfod-find too small
    ```

    NOTE: We decided to not do a bootstrap build of clang.

    NOTE: To disable PGO change `%bcond_without pgo` to `%bcond_with pgo` in the one
    line where it is conditionally defined. All the relevant changes are
    build-condition fenced with `%if %{with pgo}`.

    Disable offload on ppc64le on RHEL <= 9

    1. Add a conditional in order to control the build of offload libraries.
    2. Use this conditional when building for %{ix86}.
    3. Disable the build of offload for ppc64le on RHEL <= 9 due to the lack
       of support for the IBM long double format. As offload starts to
       depend more on libc on LLVM 21, it started to depend on long double
       code that never supported the IBM long double format.

    Do not create symlinks on i686

    Currently, it's not possible to install llvm-devel.i686 and
    llvm-devel.x86_64 at the same time, breaking multilib support.
    The reason is that binary symlinks between the two packages
    conflict, and unlikely for file conflicts, dnf treats these as
    an error.

    Fix this by not shipping any symlinks in the default prefix on
    i686. This means that i686 packages only ship the contents of
    /usr/lib/llvmN. This allows conflict-free co-installation with
    the x86_64 packages.

    I have opted to drop *all* of the symlinks in the default prefix
    on i686, but this is not strictly necessary. E.g. keeping lib
    symlinks should be fine. But I think it's cleaner to just say
    that i686 has everything in the llvm prefix only, rather than
    trying to be more precise.

    Remove alternatives support for llvm-config

    llvm-config and llvm-config-N are now plain symlinks to the
    llvm-config in the llvm prefix, just like all other binaries.

    In order to remove the old alternaties setup, I'm running
    alternatives --remove-all in a pre scriptlet. This should remove
    the old alternatives before the new symlink directly owned by
    the package is added.

    This also fixes https://bugzilla.redhat.com/show_bug.cgi?id=2361779.

Subject: [PATCH] [GlobalMerge][PPC] Don't merge globals in llvm.metadata
section
The llvm.metadata section is not emitted and has special semantics.
We should not merge globals in it, similarly to how we already
skip merging of `llvm.xyz` globals.
Fixes https://github.com/llvm/llvm-project/issues/131394.

Subject: [PATCH] Filter out configuration file from compile commands
The commands to run the compilation when printed with `-###` contain
various irrelevant lines for the perf-training. Most of them are
filtered out already but when configured with
`CLANG_CONFIG_FILE_SYSTEM_DIR` a new line like the following is
added and needs to be filtered out:
`Configuration file: /etc/clang/x86_64-redhat-linux-gnu-clang.cfg`
