I don't think it's really any different to most tests in LLVM: we generally try to make the test function on Windows and Linux hosts (and Mach-O and so on), even if the functionality is Linux specific, unless it would require things that simply aren't available on a given OS. I think the logic is that a Windows developer should be able to modify the code in this area without needing a Linux setup and be able to rely on the tests covering them from accidentally breaking things.
