[Nouveau] NV40 LLVM Backend Status

[Alex]

Bonjour.

(1) Is there any other open source GPU backend in LLVM?

(2) I'd like to know the current status and plan of NV40 LLVM backend.
Does it work?

I cloned from git://anongit.freedesktop.org/~marcheu/llvm, but it
seems that a lot of code are stilling missing.

I've done a search on Nouveau wiki and mailing list but what I only found is:
"Marcheu is working on and off on LLVM for NV4 to NV20 cards with
optimizations for NV30. That would allow Nouveau to translate shaders
into fixed function stuff

"

Best Regards, Alex.
