154
155 This file really contains two implementations of the COFF back end.
156 They are in the process of being merged, but this is only a
157 preliminary, mechanical merging. Many definitions that are
158 identical between the two are still found in both versions.
159
160 The first version, with BFD_ASSEMBLER defined, uses high-level BFD
161 interfaces and data structures. The second version, with
162 BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping
163 data structures and for doing the actual I/O. The latter defines
164 the preprocessor symbols BFD and BFD_HEADERS. Try not to let this
165 confuse you.
166
167 These two are in the process of being merged, and eventually the
168 BFD_ASSEMBLER version should take over completely. Release timing
169 issues and namespace problems convinced me to merge the two
170 together in this fashion, a little sooner than I would have liked.
171 The real merge should be much better done by the time the next
172 release comes out.
173
174 For now, the structure of this file is:
175 <common>
176 #ifdef BFD_ASSEMBLER
177 <one version>
178 #else
179 <other version>
180 #endif
181 <common>
182 Unfortunately, the common portions are very small at the moment,
183 and many declarations or definitions are duplicated. The structure
184 of obj-coff.c is similar.
185
186 See doc/internals.texi for a brief discussion of the history, if
187 you care.
