I just saw this post on hackernews, where an LLVM compiler backend ( github ) was posted that claims to get 10-20x compile time speedup compared to an LLVM 19 baseline. Quoting from the linked LLVM-Discourse thread: How to use TPDE-LLVM? The LLVM back-end is usable as a library (e.g., for JIT comp…

[image] TPDE: A Fast Adaptable Compiler Back-End Framework Offtopic Researchers from the Technical University of Munich (TUM) have announced TPDE as a fast and adaptable compiler back-end framework. I wonder if it could be useful to Julia in the future.

Thanks for linking this, I didn’t see that post. The feasibility question isn’t really resolved in that thread either, though. Happy to continue the discussion there though.
