[Haskell-cafe] ANNOUNCE: nobench: Haskell implementaion benchmarks. GHC v Hugs v Yhc v NHC v ...

[Matthew Naylor]

Hi all,

> GHC v Hugs v Yhc v NHC v ...

     ...        Hacle & Clean!

I shoved 5 of the benchmarks that Donald used through Hacle, and
compiled the outputs using version 2.1 of the Clean compiler.  Results
are below.

As for the other examples, Hacle doesn't like non-Haskell98 and
translates arbitrary-precision integers to fixed-precision ones (!)

I'm not sure how well Hacle would work with nobench because input
files must be unambiguously-typed assuming a "default ()" at the top.
So some programs may require a little tweaking to go through.  Mind,
this was only a problem on 1 of the 5 programs I just tried...

Matt.

(Note: ignore the "65536" at the end of each Clean result -- my fault
for not compiling with the right options)
