RH		 204 They are in the process of being merged, but this is only a
205 preliminary, mechanical merging. Many definitions that are
206 identical between the two are still found in both versions.
207
208 The first version, with BFD_ASSEMBLER defined, uses high-level BFD
209 interfaces and data structures. The second version, with
210 BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping
211 data structures and for doing the actual I/O. The latter defines
212 the preprocessor symbols BFD and BFD_HEADERS. Try not to let this
213 confuse you.
214
215 These two are in the process of being merged, and eventually the
216 BFD_ASSEMBLER version should take over completely. Release timing
217 issues and namespace problems convinced me to merge the two
218 together in this fashion, a little sooner than I would have liked.
219 The real merge should be much better done by the time the next
220 release comes out.
221
222 For now, the structure of this file is:
223 <common>
224 #ifdef BFD_ASSEMBLER
225 <one version>
226 #else
227 <other version>
228 #endif
229 <common>
230 Unfortunately, the common portions are very small at the moment,
231 and many declarations or definitions are duplicated. The structure
232 of obj-coff.c is similar.
233
234 See doc/internals.texi for a brief discussion of the history, if
235 you care.
