# Note: This file is compiled from the following code, for
# the purpose of creating an overflowed dwo section.
# After being compiled from source, section `.debug_info.dwo`
# is changed to have length (2^32 - 30) Bytes, and added
# padding with `.fill` directive, so it is likely to
# overflow when packed with other files.
