Hi,
llvm-git (and it's predecessor llvm-svn) is intended to provide a full
implementation of the llvm/clang compiler suite. It's a huge package
that takes a lot of time and processor capacity to build.
While mesa needs llvm, it only needs a subset.
examples :
llvm-git builds with ocaml support, but mesa doesn't use ocaml at all.
llvm-minimal-git, perhaps? If it is just building the core.
mesa requires llvm and clang (compiler-rt is needed for clang) , minimal
may fit that.
llvm-git builds for lots of processor architectures not supported by
archlinux. RISC-V is one of them.
Why does llvm-git build for RISC-V at all? Who is using it?
I guess it's for cross compilation purposes.
Both extra/llvm and aur llvm-git use llvm default[1] to build all
supported architecture targets.
The full list of targets is in
https://github.com/llvm/llvm-project/blob/master/llvm/CMakeLists.txt and
shows 15 targets.
I'm not sure, but maybe MIPS is the RISC-V architecture ?
