The reason to add clang-cpp in that commit was that opencl only needed that library to work, the rest of llvm-minimal-git wasn't needed.
I guess your suggestion is related to https://aur.archlinux.org/cgit/aur.git/commit/?h=mesa-minimal-git&id=d665a1fc7ba6b907c13f0cc37ab36467e4efded5 where llvm-minimal-git was added as dep to rusticl-minimal-git ?
Have you verified if libclang.so.17.0.0 is the only thing from llvm-minimal-git rusticl needs to build opencl kernels ?
since commit : https://aur.archlinux.org/cgit/aur.git/commit/?h=llvm-minimal-git&id=6b54cc050a5bbae197285eec695e73231547fcf6 you added clang-cpp to llvm-libs-minimal-git .
But why not adding libclang to ? libclang.so libclang.so.17 libclang.so.17.0.0
The patches have been removed after mesa got changes that deal with the legacy passmanager removal, update the PKGBUILD.
llvm trunk does indeed have a hard failure during check-clang-tools but that is not related to the patches.
I haven't investigated if the test crash was reported upstream, but have not noticed issues from building with --nocheck .
Unfortunately, the patches need some work again. Various release notes diffs fail, one test and this one in Patch 3: 1 out of 4 hunks FAILED -- saving rejects to file llvm/include/llvm/LinkAllPasses.h.rej
This is the one we need to revert as 0008 :
blackmoon3, I had to add 3 more reverts just to get the original revert working again.
I've tried to add a revert for the commit you mentioned but it can't be reverted cleanly . increassing fuzz doesn't help, I think more commits need to be reverted to keep that function for clover working .
This is what I get when adding a revert for that commit between 0002 and 0001 .

Hi you should also revert this commit : https://github.com/llvm/llvm-project/commit/15977742d3ebba05a33a8eac3201ebba9c9f10e3
This allow mesa-git package to build with gallium-opencl=icd
Because mesa use this function : https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/gallium/frontends/clover/llvm/invocation.cpp#L461 that have been removed by upstream llvm
I tested the revert patch in my own llvm-minimal git repo and just compiled llvm and mesa with no problem. https://github.com/blacksky3/llvm-minimal-git.git
I just added : patch --directory="llvm-project" --reverse --fuzz=50 --strip=1 --input="${srcdir}/0001-Reland-LegacyPM-Remove-some-legacy-passes.patch" in the prepare function to let the path fully apply with no problem
This revert patch can also be applied in lib32-llvm-minimal-git for the same reasons
Reported the issue to mesa repo : https://gitlab.freedesktop.org/mesa/mesa/-/issues/8591
Thanks, will look into adding those 2 patches (and verify if that's enough for some time) this weekend.
Just tried to build llvm-minimal-git tonight and it failed when trying to apply the patches.
Reverted those 2 commits and building works again :
Added new split package spirv-llvm-translator-minimal-git as it is needed for mesa rusticl

During building you may encounter lots of coredumps, slowing build down or even dramatically reducing the responsiveness of your system.
See https://wiki.archlinux.org/title/Core_dump for solutions/workarounds .

Archlinux currently has 3 llvm git implementations
this package
llvm-git
packages created & maintained by Lordheavy, an arch developer

Why does this package exist ?
Llvm & aur llvm-git are intended to provide a full development environment of llvm/clang suite that can replace eachother completely (aur llvm-git adds some xtra functionality)
llvm-minimal-git is a stripped-down llvm trunk build with these goals :
Some of the things that are stripped out :
Maintainers (and users) should only depend on llvm-miminal-git after verifying it satisfies what they need.

When building this you are likely to see test failures in terminal output / logs.
The command used for the tests has been changed to continue regardless of failures. Incase you don't want to run the tests you can use --nocheck option of makepkg.
