Understood, you have thought about this and how you want to use it.
Atleast mesa trunk has used this method years ago, but stopped doing it because no other packages made use of it . I have no objections to adding $pkgver-$pkgrel values in llvm-git .
Keep in mind llvm-git follows upstream default branch, so will switch from 16 to 17 when upstream branches off stable 16 .
You may want to use something like 'llvm>=16' 'llvm<17' to ensure users can switch to stable 16 once it arrives.
@Lone_Wolf I understand what you are saying about so names and versions and agree it would be nice if this package added provides for the sonames with version data so other packages could add that as a run time dependency with proper heads-up when a rebuild was needed. However I think you're wrong about my suggestion being a failure: there is no harm in adding the package version information to the provides like like I showed. It does not solve the same problem as providing the soname, but it does solve a different problem. It allows this package to be used as a makedepends with version information for packages that require to be built against a minimum version newer than what is in [community] at this point. It won't provide a run-time way to keep the soname version matched, but it does provide a build time dependency that is flexible enough to be supplied by this or another future update to the stable package(s).
alerque, doing it that way will fail at runtime as packages aren't linked to external libraries using package versions but through sonames .
the command find-libprovides from devtools package can help to make those visible.
$ find-libprovides --ignore-internal llvm-git-16.0.0_r443217.0b74cb42312b-1-x86_64.pkg.tar.zst

If you run the same command on other archlinux (binary) llvm pacakges, you'll get similar results.
If this package adds those sonames to provides, applications can depend on an exact version of the shared library, get a warning when sonames change and a rebuild is necessary.
This package provides llvm but it does not do so in a way that includes the version information. Hence it is not currently possible for other packages to use it as a build time dependency with a version requirement that would let them start using the stable version when a sufficient version is released and packaged in [community] like makedepends=('llvm>=16'). This is negatively effecting builds like brave where we're unable to specify the dependencies correctly.
Here is a patch that should fix it which should apply cleanly with git am < file.patch:

Hi, I needed to install python-setuptools to clear this section. (I am using a clean chroot with only base-devel installed.)
# Include lit for running lit-based tests in other projects
pushd llvm-project/llvm/utils/lit
python setup.py install --root="$pkgdir" -O1
popd
Therefore I think it needs to be a make dependency instead of an optional dependency, because it's required to clear the package_llvm-git function by default. Unless the user is expected to intervene here, in which case I apologise for disruption.
@sir_randomuser,
Thanks for the update. Indeed ocaml-stdlib-shims is required to build this package in a clean chroot env. I updated the PKGBUILD and added ocaml-stdlib-shims.
EDIT: resolved by adding ocaml-stdlib-shims to makedepends
Hi, has anyone else been unable to build LLVM past couple of days?

ocamlfind: Package `stdlib-shims' not found - required by `integers'
This package follows the upstream llvm project and builds the very latest commit available from upstream default branch (main). It adjusts the version number dynamically on every build .
It's been building v15 since llvm 14 got its own branch as release/llvm14 early in february .
That archlinux repos still haven't switched to the latest stable release 14 doesn't matter for this (and other llvm trunk packages ).
Besides, a package that builds any fixed branch must reflect that in the name. For llvm14 that would be llvm14-git.
Feel free to start such a NEW package.
As of today this will no longer install LLVM-14, but instead LLVM-15. More specifically : llvm-git 15.0.0_r428699.ccf7dd5e813d-1
Please consider pinning to the branch for LLVM-14, or to a commit number, untill LLVM-14 is in the extras repo. In any case, the version number should be amended.

When you have this package installed applications that are built against repo-llvm/clang WILL fail unless they are rebuild against this package.
This includes QTCreator, kdevelop , mesa, intel-compute-runtime, gnome-builder to name a few.

I've looked good at clang-trunk , llvm-svn, repo llvm/clang packages and think this package is now on route to become a worthy successor to llvm-svn .
llvm-libs-git holds the runtime libraries.
llvm-git
The Package now uses a new environment variable to make ninja behave, NINJAFLAGS. If you want to use it adjust the snippet below to your desired values and add it to makepkg.conf.
Incase you are satisfied with ninja defaults you don't need to do anything.
The check() function fails rather often, but I do suggest to build with them. If build fails due to test failure you can add --nocheck to skip the tests.
