Hiya, It's time for a new release of LHC. LHC is a backend for the Glorious Glasgow Haskell Compiler, adding low-level, whole-program optimization to the system. It is based on Urban Boquist’s GRIN language, and using GHC as a frontend, we get most of its great extensions and features. Essentially, LHC uses the GHC API to convert programs to external core format - it then parses the external core, and links all the necessary modules together into a whole program for optimization. We currently have our own base library (heavily and graciously taken from GHC.) This base library is similar to GHC’s (module-names and all,) and it is compiled by LHC into external core and the package is stored for when it is needed. This also means that if you can output GHC’s external core format, then you can use LHC as a backend. Changes in this release include: * LHC requires GHC-6.12 instead of GHC-6.10. * Much simplified support infrastructure to help minimize software decay. Installation instructions can be found in this blog post: http://lhc-compiler.blogspot.com/2010/05/limited-release.html It should be noted that LHC is in its infancy and should be seen more as a toy than anything else. So, if you want a good Haskell compiler, use GHC. If you want play around with GRIN, LHC might be right for you.
