Missing OpenCL CPU support under Windows

On my system the (i think) most recent version of the AMD drivers (18.8.1, Windows 10 x64) no longer returns the CPU (FX-8350) as a valid OpenCL device.  Is this intended behavior or just a bug in my specific installation?

 

Output of my program which prompted this question (including platform description and version information):

AMD Accelerated Parallel Processing (OpenCL 2.1 AMD-APP (2671.3))
        Number of CPUs/GPUs/Devices:  0/1/1

 

Output of clinfo (only the first few lines):
