Re: [Haskell-cafe] GHC core packages: same core?

Dimitry, I *believe* ext-core will match that document, but I'm not sure of the exact status. Tim Chevalier has done a lot of great work maintaining the external core stuff and I think he is actively using the extcore library, so *that* should almost certainly match GHC's output. It's great to hear that you are interested in writing an alternative backend! I think LHC is also using ext-core to build a backend, so this seems like a viable approach. All the best, Max 2009/10/13 Dimitry Golubovsky :

Max,

Thanks for the explanation. So, the extcore library is expected to match the spec in http://www.haskell.org/ghc/docs/6.10.4/html/ext-core/core.pdf and the core itself can be produced with -fext-core, correct? I think it might be interesting for people working on alternative backends (inlcuding myself).

extcore is a library that parses "external" Core, which is an alternative format intended to be stable and hence a suitable target for consumption by non-GHC tooling. You can have GHC output external core instead of machine code / C. I don't believe this is widely used yet.
