252b5132 RH |
206 | They are in the process of being merged, but this is only a |
207 | preliminary, mechanical merging. Many definitions that are | |
208 | identical between the two are still found in both versions. | |
209 | ||
210 | The first version, with BFD_ASSEMBLER defined, uses high-level BFD | |
211 | interfaces and data structures. The second version, with | |
212 | BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping | |
213 | data structures and for doing the actual I/O. The latter defines | |
214 | the preprocessor symbols BFD and BFD_HEADERS. Try not to let this | |
215 | confuse you. | |
216 | ||
217 | These two are in the process of being merged, and eventually the | |
218 | BFD_ASSEMBLER version should take over completely. Release timing | |
219 | issues and namespace problems convinced me to merge the two | |
220 | together in this fashion, a little sooner than I would have liked. | |
221 | The real merge should be much better done by the time the next | |
222 | release comes out. | |
223 | ||
224 | For now, the structure of this file is: | |
225 | <common> | |
226 | #ifdef BFD_ASSEMBLER | |
227 | <one version> | |
228 | #else | |
229 | <other version> | |
230 | #endif | |
231 | <common> | |
232 | Unfortunately, the common portions are very small at the moment, | |
233 | and many declarations or definitions are duplicated. The structure | |
234 | of obj-coff.c is similar. | |
235 | ||
236 | See doc/internals.texi for a brief discussion of the history, if | |
237 | you care. | |
