llvm-mirror/unittests/BinaryFormat/MsgPackReaderTest.cpp
Scott Linder c46ffa9c82 [BinaryFormat] Add MessagePack reader/writer 
Add support for reading and writing MessagePack, a binary object serialization
format which aims to be more compact than text formats like JSON or YAML.

The specification can be found at
https://github.com/msgpack/msgpack/blob/master/spec.md

Will be used for encoding metadata in AMDGPU code objects.
