# Test object with an artifically constructed type unit header to verify
# that the length field is correctly used to verify the validity of the
# type_offset field.
#
# To generate the test object:
# llvm-mc -triple x86_64-unknown-linux typeunit-header.s -filetype=obj \
# -o typeunit-header.elf-x86-64
#
# We only have an abbreviation for the type unit die which is all we need.
# Real type unit dies have quite different attributes of course, but we
# just need to demonstrate an issue with validating length, so we just give it
# a single visibility attribute.
