I did some research on this topic, and after all it doesn't look so
simple as I initially though.
--list=build-info output.
Since it is build info then we should report there only what was known
at build time, not runtime - in my opinion.
Macro: __OPENCL_VERSION__ is available only during kernel compilation
and it means highest supported OCL version by THIS device.
There are also properties:
CL_DEVICE_OPENCL_C_VERSION
CL_PLATFORM_VERSION
which are available at the runtime, then I assume that we don't need them.
CL/cl.h contains:
/* OpenCL Version */
#define CL_VERSION_1_0 1
#define CL_VERSION_1_1 1
#define CL_VERSION_1_2 1
I used them to add OpenCL version to build-info output, I hope that it
is what you ment.
Patch attached,
Lukas
