# This test verifies that: if a DW_TAG_compile_unit has children not having
# ranges then llvm-dwarfdump still correctly verifies other dies with normal
# ranges.
#
# The DWARF looks like:
# 0x0000000b: DW_TAG_compile_unit
# DW_AT_name ("/tmp/main.c")
# DW_AT_language (DW_LANG_C)
# DW_AT_low_pc (0x0000000000000000)
# DW_AT_ranges (0x00000000
# [0x0000000000002000, 0x0000000000003000)
# [0x0000000000001000, 0x0000000000002000))
#
# 0x0000001e: DW_TAG_subprogram
# DW_AT_name ("no_range1")
#
# 0x00000044: DW_TAG_subprogram
# DW_AT_name ("main")
