They are in the process of being merged, but this is only a preliminary, mechanical merging. Many definitions that are identical between the two are still found in both versions. The first version, with BFD_ASSEMBLER defined, uses high-level BFD interfaces and data structures. The second version, with BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping data structures and for doing the actual I/O. The latter defines the preprocessor symbols BFD and BFD_HEADERS. Try not to let this confuse you. These two are in the process of being merged, and eventually the BFD_ASSEMBLER version should take over completely. Release timing issues and namespace problems convinced me to merge the two together in this fashion, a little sooner than I would have liked. The real merge should be much better done by the time the next release comes out. For now, the structure of this file is: #ifdef BFD_ASSEMBLER #else #endif Unfortunately, the common portions are very small at the moment, and many declarations or definitions are duplicated. The structure of obj-coff.c is similar. See doc/internals.texi for a brief discussion of the history, if you care.
