Defines the object file and target independent interfaces used by the assembler backend to write native file format object files.

The object writer contains a few callbacks used by the assembler to allow the object writer to modify the assembler data structures at appropriate points. Once assembly is complete, the object writer is given the MCAssembler instance, which contains all the symbol and section data which should be emitted as part of writeObject().
