# This test is meant to verify that the -verify option
# in llvm-dwarfdump doesn't produce any .apple_names related
# output when there's no such section in the object.
# The test was manually modified to exclude the
# .apple_names section from the apple_names_verify_num_atoms.s
# test file in the same directory.
