Hi Sylvestre, Can we please keep llvm-toolchain-14 in unstable? GHC 9.4.6 (which is the latest version used in stackage LTS, see https://www.stackage.org/) uses LLVM-14. I tried using LLVM-16 and it failed (see version 9.4.6-1~exp2 in experimental).
I plan to upload GHC 9.4.6 in unstable over the next days. Thanks, -- Ilias
