eschwartz [1] filed a deletion request for llvm-debug [2]: Package is inaccurately named -- it packages llvm 3.5. Additionally debug packages for repository packages can be created by checking out the repo PKGBUILD and rebuilding with modifications to makepkg.conf, so there's no need to create AUR packages for it that don't get kept up to date.
Users claim this package doesn't even build currently. [1] https://aur.archlinux.org/account/eschwartz/ [2] https://aur.archlinux.org/pkgbase/llvm-debug/
