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

## bar.a is under %t/%:t, and so verifies that rerooting happens. foo.a isn't,
