LLVM9

• pikopixel: unpin llvm9 #283653

Issues

cling

• cling can build updated interpreter but requires copying c/c++ header files. unclear what version to use to update the package as it also needs to interface with xeus-cling which claims to support for >= 0.9 but less than < 0.10 (1.0)
• xeus-cling a jupyter kernel and the only consumer of cling

haskell

• haskell code contains one heavily used llvm_9 reference

llvm-hs is marked broken at the moment. It is unclear to me what the status of the project is at the moment. There are branches that support later versions, but there are no such releases uploaded to Hackage.
