            Bug ID: 44511
           Summary: DWARFYAML::EmitDebugAbbrev is missing a final 0
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux

llvm-dwarfdump works either with or without a final 0, but the spec may require
it, and the gimli-rs parser errors without it.

Adding

  writeInteger((uint8_t)0, OS, true /* isLittleEndian */);

on the final line of

https://github.com/llvm/llvm-project/blob/ab411801b82783eb7f652701ccfce81b16cf1811/llvm/lib/ObjectYAML/DWARFEmitter.cpp#L78

appears to fix things, but is likely not the proper fix there.
