187 | ||
188 | This file really contains two implementations of the COFF back end. | |
189 | They are in the process of being merged, but this is only a | |
190 | preliminary, mechanical merging. Many definitions that are | |
191 | identical between the two are still found in both versions. | |
192 | ||
193 | The first version, with BFD_ASSEMBLER defined, uses high-level BFD | |
194 | interfaces and data structures. The second version, with | |
195 | BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping | |
196 | data structures and for doing the actual I/O. The latter defines | |
197 | the preprocessor symbols BFD and BFD_HEADERS. Try not to let this | |
198 | confuse you. | |
199 | ||
200 | These two are in the process of being merged, and eventually the | |
201 | BFD_ASSEMBLER version should take over completely. Release timing | |
202 | issues and namespace problems convinced me to merge the two | |
203 | together in this fashion, a little sooner than I would have liked. | |
204 | The real merge should be much better done by the time the next | |
205 | release comes out. | |
206 | ||
207 | For now, the structure of this file is: | |
208 | <common> | |
209 | #ifdef BFD_ASSEMBLER | |
210 | <one version> | |
211 | #else | |
212 | <other version> | |
213 | #endif | |
214 | <common> | |
215 | Unfortunately, the common portions are very small at the moment, | |
216 | and many declarations or definitions are duplicated. The structure | |
217 | of obj-coff.c is similar. | |
218 | ||
219 | See doc/internals.texi for a brief discussion of the history, if | |
220 | you care. | |
