   6 ## This test verifies that we attempt to re-root absolute paths if -syslibroot
   7 ## is specified. Therefore we would like to be able to specify an absolute path
   8 ## without worrying that it may match an actual file on the system outside the
   9 ## syslibroot. `chroot` would do the job but isn't cross-platform, so I've used
  10 ## this %t/%:t hack instead.

  17 ## bar.a is under %t/%:t, and so verifies that rerooting happens. foo.a isn't,
  18 ## and therefore verifies that we still fall back to the original path if no
  19 ## file exists at the rerooted path.
