Commenting out just the check() function made it compile after two previous failures for me – also I see that https://aur.archlinux.org/packages/lib32-llvm-minimal-git/ PKGBUILD is different and among some doesn't include that check, although I didn't try compiling it yet (EDIT: it works fine).
EDIT: Alternatively, it works by disabling check via --nocheck or stating BUILDENV=([…] !check […])
@Octobot : clang regresssion tests fail so often I'm tempted to remove them from the check() function. Usually they go away(and are sometimes replaced by others) after a few days when upstream solved them.
@Sinistar llvm-minimal-git gives more warnings then in the past, but other then that I haven't encountered problems with it or mesa-git using llvm-minimal-git & gcc9 . Will test llvm-git in a few days.
Just a heads up, GCC 9.X seems to be messed up. LLVM will compile fine with clang, or GCC 8.X. Also, MESA will compile ok with GCC 8.X. If you use clang to compile LLVM you will also need to use gold as the linker and add clang as a makedepends.
Example:
-D CMAKE_C_COMPILER=/usr/bin/clang \
-D CMAKE_CXX_COMPILER=/usr/bin/clang++ \
-D LLVM_USE_LINKER=gold \
It seems no matter what I do, I am unable to successfully build this or the full llvm-git packages. Both ceaselessly fail during regression testing. In the case of llvm-minimal, the results are as follows:

Depends on your umask (I default to a non-permissive one) and how you build the package.
Looks like that file already has 644 permissions.

Minor tweak to ensure /usr/include/llvm/Config/llvm-config.h permissions are right:

The PKGBUILD should use ninja $NINJAFLAGS (not ninja "$NINJAFLAGS"), so the value is properly split (e.g. when using NINJAFLAGS="-j3 -k0") and it works when it's empty.
@Lone_Wolf and now package doesn't work OOB because user should set unofficial undocumented NINJAFLAGS?
Fail with /var/tmp/pamac-build-jojo/llvm-minimal-git/src/_build/ empty error.

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.
