[Bf-committers] CUDA compiler open-sourced

[Erwin Coumans]

AMD open sourced their OpenCL GPU LLVM backend a few days earlier,
http://lists.cs.uiuc.edu/pipermail/llvmdev/2011-December/046136.html

No matter how hard NVIDIA pushes their CUDA tech,
I think it is unlikely that Intel, AMD and others will dropping
support for the open standard OpenCL in favor of CUDA.

By the way, I hear comments by Brecht that AMD OpenCL is lacking
for Cycles. Where are the details on that?

Thanks!
Erwin
