llvm-mirror/lib/ObjectYAML/ArchiveEmitter.cpp
Georgii Rymar 5ef47e6205 [yaml2obj][obj2yaml] - Teach tools to work with regular archives.
This teaches obj2yaml to dump valid regular (not thin) archives.
This also teaches yaml2obj to recognize archives YAML descriptions,
what allows to craft all different kinds of archives (valid and broken ones).
