Ruby.

I still love the language, and maintain my SSG that was written in Ruby over a decade ago. Shame that it's nearly dead now.

LLVM deprioritizes helper scripts such as update_analyze_test_checks.py, and the build infrastructure is far from perfect. Scripts like the ones categorizing PRs are very much unpaid work.

LLVM also deprioritizes general cleanup work, such as getting rid off passes that don’t work, and are rotting in the tree: of the top of my head, I can think of GVNSink, LoopFusion.

There are additional problems unique to LLVM, as it doesn’t have a dictator: there are multiple different dependence analysis in tree, for instance.
