MarsSeed [1] filed a deletion request for lib32-cloog [2]: I suggest for easing maintenance burden that this package is not needed and can be deleted. Even for compiling multilib gcc it seems only the native build of cloog is used, not its lib32-on-64-bit variant. Nothing depends on this package. Arch has adopted the former AUR/isl package under the name 'libsl'. This is causing problems while other AUR isl packages get renamed, and AUR depemdents switch over to using libisl, not isl. So the less unneeded consumers of the legacy packages isl or lib32-isl, the better. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/lib32-cloog/
