# 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.
