A thought that came to my mind was whether we should focus on getting better code out of the llvm backend or the native code generator. LLVM seems pretty good at the specialized task of code generation and low level optimization, it is well funded, widely used and has a big community support. That allows us to leverage that huge effort and take advantage of the new developments. Does it make sense to outsource the code generation and low level optimization tasks to llvm and ghc focussing on higher level optimizations which are harder to do at the llvm level? What are the downsides of using llvm exclusively in future?
Good reading IMHO about the topic is here: https://ghc.haskell.org/trac/ghc/wiki/ImprovedLLVMBackend Cheers, Karel
