22/// \brief Streaming object file generation interface.
23///
24/// This class provides an implementation of the MCStreamer interface which is
25/// suitable for use with the assembler backend. Specific object file formats
26/// are expected to subclass this interface to implement directives specific
27/// to that file format or custom semantics expected by the object writer
28/// implementation.
