Lemmih: LHC - past, present and future

Here’s the abstract for Friday’s talk:

GHC is the undisputed master of high-level Haskell optimizations. With its fine-tuned simplifier and user-programmable rewriting rules, GHC has shown that Haskell can be very competitive when it comes to performance. However, woefully little attention has been directed at low-level optimizations which are becoming more significant as high-level optimization opportunities become scarce.

This talk is about the LHC Haskell Compiler and how it attempts to bring another level of optimizations to Haskell programs. I will cover why LHC was created, how far we’ve come with its development and what features we’re aiming at including.
