I'm having trouble parsing/understanding what you mean. Could you please elaborate?

The haskell98 package is included + the packages/libraries/modules on which the haskell98 pakage depends. However this currently is only provided for the default (interpreter based) backend. hope this clarifies, cheers,

Thanks, Jason

John, UHC cannot compile itself: some of the used libraries use non-Haskell98 features still absent in UHC (e.g. functional dependencies). Runtime system comparison depends on what topic you want to compare on, otherwise UHC's runtime system just corresponds to what UHC supports, and thus obviously lacks what GHC does support and UHC does not (e.g. parallelism related features). regards, On 24 Sep, 2010, at 19:36 , John Van Enk wrote:

Can UHC self-host yet? How does the runtime compare to GHC's? I suppose I could just go look... :)

The UHC team is happy to announce the second public release of the Utrecht Haskell Compiler (UHC). UHC supports almost allmost all Haskell98 and Haskell2010 features plus some experimental extensions. The compiler runs on MacOSX, Windows (cygwin), and various Unix flavors.

This second release has the following highlights relative to the previous first release:

* Supports most of the Haskell2010 features.

* Generic deriving [1].

* UHC knows about packages, and Cabal version 1.9.3 and later have basic support for UHC, so that Cabal can be used to build UHC packages.

* For the default backend libraries are provided until including package haskell98.

* The runtime system is no longer dependent on Boehm garbage collector, but uses UHCs own, a swap space collector allowing parameterization with backend specifics.

* More programs from the nofib test suite compile and run.

* Many smaller and larger problems fixed.

Getting started & Download --------------------------

UHC is available for download as source distribution via the UHC home page:

http://www.cs.uu.nl/wiki/UHC

Here you will also find instructions to get started and the specifics of what UHC can and cannot do.

Status of the implementation ----------------------------

Over the past year much effort by many people has been put into improving UHC, in particular to make it compile and run more library modules and test programs. Although the UHC project is very much work in progress overall reliability has improved, bugs have been fixed, and some Hackage packages compile.

Warning -------

Although we think that the compiler is stable enough to compile substantial Haskell programs, we do not recommend yet to use it for any serious development work in Haskell. We ourselves use the GHC as a development platform! We think however that it provides a great platform for experimenting with language implementations, language extensions, etc.

Mailing lists -------------
