llvm dev - Feb 2010 - [LLVMdev] glasgow haskell appears to be adopting LLVM

everyone--

File this under Advocacy.

See this thread
<http://www.haskell.org/pipermail/glasgow-haskell-users/2010-February/018425.html>
for more information, but the short summary is that they're deprecating
their old "compile to GCC" backend in favor of David Terei's new
LLVM backend.  They're still planning for their C-- backend to be the
primary backend for native code generation, but by bundling LLVM with the GHC
sources, they'll be able to remove a whole passle of Perl and GCC-related
crawling horrors.  They're hoping to get some performance improvements out
of the migration.

Let us all now give a warm welcome to our new Haskell comrades!

Very nice, care to add a GHC entry to the LLVM Users page?

This is very cool! 

I thought when I first read Terei's paper's abstract that there would
not be a motivation to progress
ghc toward an llvm backend given no improvement in speed even with llvm
optimizations turned
on. I completely missed the part about simplicity. I now need to read the paper.
:-) Interesting thread
by the way.

Hopefully Mono will be next.

Mono has already used LLVM for various things.

I'll prepare a patch that could be applied when the merge is formally
released by the GHC developers.
