RUN: llvm-dwarfdump %p/Inputs/dwarfdump-header.elf-x86-64 | FileCheck %s

The input file is hand-coded assembler to generate all the units,
so we're willing to make exact checks for offsets and such.

CHECK-LABEL: .debug_info contents:

The v4 CU header.

CHECK: 0x00000000: Compile Unit: length = 0x00000015 version = 0x0004 abbr_offset = 0x0000 addr_size = 0x08 (next unit at 0x00000019)
CHECK: 0x0000000b: DW_TAG_compile_unit

The v5 normal CU header.

CHECK-LABEL: .debug_types contents:

The v4 type unit header.

CHECK: 0x00000017: DW_TAG_type_unit

FIXME: DWARF v5 wants type units in .debug_info[.dwo] not .debug_types[.dwo].
