141 This file really contains two implementations of the COFF back end.
142 They are in the process of being merged, but this is only a
143 preliminary, mechanical merging. Many definitions that are
144 identical between the two are still found in both versions.
145
146 The first version, with BFD_ASSEMBLER defined, uses high-level BFD
147 interfaces and data structures. The second version, with
148 BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping
149 data structures and for doing the actual I/O. The latter defines
150 the preprocessor symbols BFD and BFD_HEADERS. Try not to let this
151 confuse you.
152
153 These two are in the process of being merged, and eventually the
154 BFD_ASSEMBLER version should take over completely. Release timing
155 issues and namespace problems convinced me to merge the two
156 together in this fashion, a little sooner than I would have liked.
157 The real merge should be much better done by the time the next
158 release comes out.
159
160 For now, the structure of this file is:
161 <common>
162 #ifdef BFD_ASSEMBLER
163 <one version>
164 #else
165 <other version>
166 #endif
167 <common>
168 Unfortunately, the common portions are very small at the moment,
169 and many declarations or definitions are duplicated. The structure
170 of obj-coff.c is similar.
171
172 See doc/internals.texi for a brief discussion of the history, if
173 you care.
