Why are there 4 devices in the generic-elf plugin?

The generic-elf-64bit plugin has 4 devices. Is there a reason for this?
I tried looking through the commit history, but it appears that way in the initial commit.

It looks a little strange to see all the generic-elf-64bit devices in the llvm-omp-device-info output.

My money is on “quad-core” being the latest thing.
