[Beignet] Fwd: clSetKernelArg CL_INVALID_ARG_SIZE error

[Song, Ruiling]

Yes, it is a beignet bug, OpenCL spec specifies sizeof(float3) same as sizeof(float4).
So using sizeof(cl_float3) when you call clSetKernelArg is the right way.
I will send a patch to fix it.

Subject: [Beignet] Fwd: clSetKernelArg CL_INVALID_ARG_SIZE error

I have a kernel with float3 argument. In C++ code I use cl_float3 (which is actually cl_float4). When I call clSetKernelArg with 3rd argument sizeof(cl_float3) it gives me an error CL_INVALID_ARG_SIZE. If i use my own structure with just 3 floats - it works. With NVIDIA it works with cl_float3 just fine. Is it a bug?
