My guess is that this enables some kind of "population count" functionality in the OpenCL C language, but as there doesn't appear to be a public page on khronos.org at the moment, nor does there appear to be any documentation on AMD's site about Stream SDK 2.3 even though the Catalyst 10.12 drivers released yesterday include 2.3, we will just have to wait until these documents go live.
and documentation to cl_amd_device_attribute_query will be nice too.
oh i am blind. well there is also cl_amd_event_callback
cl_amd_popcnt most probably maps into IL's icbits and further maps into ISA's BCNT_INT.
