Zubin pushed to branch wip/9.12.3-backports at Glasgow Haskell Compiler / GHC Commits: 316e99e8 by Ben Gamari at 2025-12-08T15:05:28+05:30 Revert "configure: do not set LLC/OPT/LLVMAS fallback values when FIND_LLVM_PROG fails" While dropping these fallbacks is likely the right thing in the long run, doing so now makes it needlessly difficult for users to use the LLVM backend. See #26209. This will change once `ghc-toolchain` becomes the default path. This reverts commit 4eb5ad09cf93caa5791a735baa0e7ba86b916f2a.
