Hi everyone. This is a fantastic tool, thank you for making it.

I've seen a couple references to llvm in github but I'm having trouble compiling with llvm normally. if I just add -fllvm to my GHC options in my .cabal file it says GHC isn't configured for llvm use. If I set basePackages = pkgs.pkgsLLVM.haskell.packages.ghc912; then all my settings overrides in perSystem.haskellProjects.default.settings stop working. Any advice? Thank you.

actually hold that thought, this problem seem to only happen when using something unusual for inputs.source or >= ghc.9.10.

maybe also only on aarch-64-linux
