So practically speaking, OpenCL 2.0 is the best you can get, unless you want to run on Intel's iGPUs or Intel's AVX 512 on their CPUs.
AMD does have support of C++ in OpenCL 1.2 as an optional extension, but their support of C++ in OpenCL 1.2 doesn't work when you enable OpenCL 2.0 for some reason. Also, the CodeXL debugger only works on OpenCL 1.2 at the moment...
As far as I can tell, AMD's implementation of OpenCL 2.0 is still early stage. Its fine if you're cool with debugging with "printf" statements.
