159
160 This file really contains two implementations of the COFF back end.
161 They are in the process of being merged, but this is only a
162 preliminary, mechanical merging. Many definitions that are
163 identical between the two are still found in both versions.
164
165 The first version, with BFD_ASSEMBLER defined, uses high-level BFD
166 interfaces and data structures. The second version, with
167 BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping
168 data structures and for doing the actual I/O. The latter defines
169 the preprocessor symbols BFD and BFD_HEADERS. Try not to let this
170 confuse you.
171
172 These two are in the process of being merged, and eventually the
173 BFD_ASSEMBLER version should take over completely. Release timing
174 issues and namespace problems convinced me to merge the two
175 together in this fashion, a little sooner than I would have liked.
176 The real merge should be much better done by the time the next
177 release comes out.
178
179 For now, the structure of this file is:
180 <common>
181 #ifdef BFD_ASSEMBLER
182 <one version>
183 #else
184 <other version>
185 #endif
186 <common>
187 Unfortunately, the common portions are very small at the moment,
188 and many declarations or definitions are duplicated. The structure
189 of obj-coff.c is similar.
190
191 See doc/internals.texi for a brief discussion of the history, if
192 you care.
