I've never been able to use the opencl that builds with mesa-git in the applications I have. I've tried running GPU calculations with Folding@Home, and benchmarking hashcat and they both fail unless I use the amdgpu driver version in the opencl-amd package. The failure message I get is in the code block below. Have you seen similar results? clinfo reports the mesa version is OpenCL 1.1.
clBuildProgram(): CL_BUILD_PROGRAM_FAILURE
fatal error: cannot open file '/usr/lib/clc/gfx1010-amdgcn-mesa-mesa3d.bc': No such file or directory
* Device #1: Kernel /usr/share/hashcat/OpenCL/shared.cl build failed.
clinfo results in a very similar error.
=== CL_PROGRAM_BUILD_LOG ===

removed obsolete options, build now works again.
building opencl clover is disabled for now, see https://gitlab.freedesktop.org/mesa/mesa/-/issues/11863
Those that need opencl should use rusticl instead. Note that rusticl at runtime is disabled by default, see https://docs.mesa3d.org/envvars.html#rusticl-environment-variables for info about enabling it.

Mesa and llvm are closely tied together. Everytime the llvm mesa is built against changes/updates , mesa needs to be rebuilt.
I expect anyone building mesa-git against one of the llvm trunk variants to be able to do that themselves, but atleast some of the people that built against repo llvm don't understand how to deal with such a rebuild.
The rest of this post is meant for those people.
Option A - best one
see https://wiki.archlinux.org/index.php/DeveloperWiki:Building_in_a_clean_chroot for the official way or https://aur.archlinux.org/packages/clean-chroot-manager for an alternative method.
Option B - 2nd best

WARNING : aur helpers don't support this method at all. They check .SRCINFO and that doesn't include this variable so it will use the default which is hardcoded to build against repo llvm.
Why would I want to use llvm development versions ?

run pacman Syu update non-repo packages for llvm if you use them
build mesa-git, log out , update mesa-git and restart X .
run
