llvm dev - Apr 2021 - [YAML][DebugInfo] Split DWARF with YAML

Hi Xing,

The same I've figured out when looking at DWARF implementation from
ObjestYAML.

Hi Djordje,

AFAIK, yaml2obj doesn't support writing "dwo" sections. It might
be a
good idea to add split DWARF support to yaml2obj.

Right, as Xing mentioned, I don't think any support has been added to
yaml2obj for the .dwo sections yet. You might be able to workaround it by
pretending they are regular DWARF sections and then using llvm-objcopy to
rename the necessary sections, but I would think adding yaml2obj support
would be the better option.
