# REQUIRES: x86
# UNSUPPORTED: system-windows
## FIXME: In principle this test should pass on Windows
# RUN: rm -rf %t; split-file %s %t
## 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.
# RUN: mkdir -p %t/%:t
# RUN: llvm-mc -filetype=obj -triple=x86_64-apple-darwin %t/foo.s -o %t/foo.o

# RUN: llvm-mc -filetype=obj -triple=x86_64-apple-darwin %t/test.s -o %t/test.o
## bar.a is under %t/%:t, and so verifies that rerooting happens. foo.a isn't,
## and therefore verifies that we still fall back to the original path if no
## file exists at the rerooted path.
# RUN: llvm-ar rcs %t/foo.a %t/foo.o
# RUN: %lld -dylib %t/foo.o -o %t/libfoo.dylib
