MarsSeed [1] filed a deletion request for seexpr2 [2]: Legacy seexpr version from 2018. Its llvm7 dependency is reported broken since 2020.
But no other package on AUR requires this, only the newer seexpr packages have dependents. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/seexpr2/
