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. | |
