Actually, we don't support double completely currently. Let's disable it now. This bring a little incompatible point with the 1.2 spec which doesn't require the kernel to use the following pragma to enable fp64. #pragma OPENCL EXTENSION cl_khr_fp64 : enable
If the application wants to try the partially supported double with beignet under opencl 1.2, the application will still need to add the above pragma.
