i was googling around to try to get a better idea on the discussion happening here and i found this quote by Zack Rusin:

In the case of AMD it's even sadder because the crucial code that we need for OpenCL right now is OpenCL C -> TGSI LLVM backend which AMD already does for their IL. Some poor schmuck will have to sit down and write more/less the same code."

does this mean that AMD has already writtern the code we need to make it run on GPUs ????
