[Haskell-cafe] shootout using 6.6?

Anyone know if the Language Shootout is actually using GHC 6.6 or is that a
typo?

Thanks,
Greg

Cool! It shall be done!

Mea culpa - when I was considering building ghc from source I seem to
have unmerged ghc, so ghc-6.8.2 didn't show up in the portage updates.

It's using 6.6 till the gentoo 6.8 package is more widely distributed.

Note that ghc-6.8.2 is in gentoo now and has been for a few weeks.
There's no reason not to use it.

Great. Do let us know when its available. A couple of benchmarks
will need to be tweaked in light of library changes.

I'm also hoping to see good speedups for constructor-matching
heavy programs like binary-trees.

Thanks for all your efforts here Isaac!

Yay, constructor specialisation!

Looks like there's a few regressions, and a few failures. 

We can coordinate fixes on the wiki,

Cheers,

Yes that was a good speed up :-)

otoh there are several failing programs...

And it's nice to see GHC 6.8.2 is now nearly ten times faster than
GCC for this benchmark :

Scary to think how fast GHC might become in 6.10 :)
