LLVM is coming to Haskell, in the form of David Terei's LLVM backend which is being merged into mainline GHC. Based on that, GHC seems to be also dropping it's C backend, in favour of their own native code generator and LLVM as fall-back, wherever the former is not yet available/feasible.And while we are in Haskell-land: the
uvector package is now deprecated in favour of vector, which now provides the same performance but not only makes all those U suffices go away, but is also more versatile. Why should you care at all about vector (or uvector, for that matter)? Two words: Loop fusion (based on DPH work)! To spread his excitement, Don Stewart has started "Numeric Haskell: A Vector Tutorial" which, based on the NumPy tutorial, nicely introduces using vector in Haskell.Addendum 2010-02-22: Don Stewart did some micro-benchmarking of GHC's native, C and LLVM backends using the
vector package.
