# This test relies on locking files which is difficult to do in a way the keeps
# a test robust on Linux, so it is restricted to Windows.
REQUIRES: ld.lld,system-windows

# Test that a warning is emitted for each DTLTO temporary file that cannot be
# removed. This test uses archives because archive handling exercises a superset
# of the temporary files used for object inputs.
#
# This scenario is logically related to the cases in savetemps.test; however, it
# is placed here to maintain coverage, as this behavior can only be tested
# effectively on Windows.
