252b5132
RH		 206 They are in the process of being merged, but this is only a
207 preliminary, mechanical merging. Many definitions that are
208 identical between the two are still found in both versions.
209
210 The first version, with BFD_ASSEMBLER defined, uses high-level BFD
211 interfaces and data structures. The second version, with
212 BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping
213 data structures and for doing the actual I/O. The latter defines
214 the preprocessor symbols BFD and BFD_HEADERS. Try not to let this
215 confuse you.
216
217 These two are in the process of being merged, and eventually the
218 BFD_ASSEMBLER version should take over completely. Release timing
219 issues and namespace problems convinced me to merge the two
220 together in this fashion, a little sooner than I would have liked.
221 The real merge should be much better done by the time the next
222 release comes out.
223
224 For now, the structure of this file is:
225 <common>
226 #ifdef BFD_ASSEMBLER
227 <one version>
228 #else
229 <other version>
230 #endif
231 <common>
232 Unfortunately, the common portions are very small at the moment,
233 and many declarations or definitions are duplicated. The structure
234 of obj-coff.c is similar.
235
236 See doc/internals.texi for a brief discussion of the history, if
237 you care.
