Re: Re: Standard Portable Intermediate Representation (SPIR)

I confirm this (see last extension bellow). Does this mean that SPIR is already implemented in the AMD driver?

Re: Standard Portable Intermediate Representation (SPIR)

Interesting! Now we just need the clc.exe to precompile our code

I'm not sure if the precompiler app will be done by Khronos or directly by the IHVs like AMD, NVIDIA or Intel in their OpenCL SDKs.,,
