Thanks for confirming it works that way.
An issue with using --force-fallback-for is that the PKGBUILD no longer controls what is downloaded and from where.
In repo mesa 'meson subprojects' are used, like
# Rust crates for NVK, used as Meson subprojects
declare -A _crates=(
proc-macro2 1.0.70
quote 1.0.33
syn 2.0.39
unicode-ident 1.0.12
)
for _crate in "${!_crates[@]}"; do
source+=($_crate-${_crates[$_crate]}.tar.gz::https://crates.io/api/v1/crates/$_crate/${_crates[$_crate]}/download)
done
# Inject subproject packages
export MESON_PACKAGE_CACHE_DIR="$srcdir"

To those with the directx errors : archlinux directx-headers pacakgae is 2 releases behind upstream. Try building against aur directx-headers-git .
I don't remember what d3d12 does, but offical mesa also supports it.
@ZephyrCheez : thanks, that option lead to meson subprojects and mesa sourcetree does appear to include the data needed to use them. Adding nouveau vulkan looks doable now, no idea when there will be time to implement it.

@Beiruty, those have the same cause as the other recent build failures : changes in intel drivers.
The build issues caused by changes in intel drivers are now solved for MESA_WHICH_LLVM 1, 3 and 4 (llvm-minimal-git , llvm from lordheavy unofficial repo and offical repo llvm )
MESA_WHICH_LLVM 2 (aur llvm-git) build is still broken, but I MAY have a solution for that without having to create new packages.
The good news is that once all 4 variants built again, only minor changes should be needed to add opencl clover & opencl rusticl support.
(A lot of the work required to built the intel drivers is also useful for clover & rusticl)

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 onesee 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 bestLone_Wolf commented on 2019-07-09 13:43 (UTC) (edited on 2023-04-18 10:41 (UTC) by Lone_Wolf)
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 .
