Tom Stellard's presentation 

At the XDC2011, we discussed how GPGPU should be handled and we kind of agreed
on what we should do. This can basically be summed up as using the LLVM IR for
compute. This means we need to implement LLVM backends for our GPUs. See the
Mesa_compilers.pdf attachment.

The OpenCL frontend has been implemented by Denis Steckelmacher during the GSoC
2011 (https://steckdenis.wordpress.com/2011/08/23/the-gsoc-is-over/) that
currently works on the CPU only.

This implementation work can be done by a newcomer, it requires knowledge (or
willing to get it) in compilers. Please contact Martin Peres(mupuf) to get
started. We'll see who can mentor your work.
