r296171 - Try to unbreak tests after r296166

[Yung, Douglas via cfe-commits]

Thanks Nico. I think your suggestion is the right one, I am just trying to determine if there is a reason why we are not using that version internally (since our internal bot also failied for the same reason) before we recommend upgrading the bot.

I relanded the test in r296408. Since this deletes temp files created by the OS following an unpredictable pattern, exactly specifying the filename to delete isn't possible. Let me know if putting a functional rm on your bots is a problem and then we can see if we can think of something else, but fixing your bots's rm seems easiest to me :-)

Can't you just put gnuwin rm on your bot? Our Windows bots are happy with the test, and having to support an rm without wildcard support seems pretty strange. (Https://is.gd/chromeclang -> tools -> gnuwin-6.zip are the executables our bot uses to run llvm tests)

Hi Nico,

The test you added is causing a failure on the PS4 Windows bot. The root of the cause is that the Windows version of rm does not accept wildcards unfortunately. To fix make it work on Windows, you likely need to specify exactly what files/directories you want to delete without using a wildcard:

http://lab.llvm.org:8011/builders/llvm-clang-lld-x86_64-scei-ps4-windows10pro-fast/builds/6030:

$ "rm" "C:\Buildbot\Slave\llvm-clang-lld-x86_64-scei-ps4-windows10pro-fast\llvm.obj\tools\clang\test\Format\Output/*"
# command stderr:
rm: cannot remove `C:\\Buildbot\\Slave\\llvm-clang-lld-x86_64-scei-ps4-windows10pro-fast\\llvm.obj\\tools\\clang\\test\\Format\\Output/*': Invalid argument

http://lab.llvm.org:8011/builders/llvm-clang-lld-x86_64-scei-ps4-windows10pro-fast/builds/6031:

$ "rm" "C:\Buildbot\Slave\llvm-clang-lld-x86_64-scei-ps4-windows10pro-fast\llvm.obj\tools\clang\test\Format\Output/inplace*"
# command stderr:
rm: cannot remove `C:\\Buildbot\\Slave\\llvm-clang-lld-x86_64-scei-ps4-windows10pro-fast\\llvm.obj\\tools\\clang\\test\\Format\\Output/inplace*': Invalid argument

Can you fix the test?
