| 164 | ||
| 165 | This file really contains two implementations of the COFF back end. | |
| 166 | They are in the process of being merged, but this is only a | |
| 167 | preliminary, mechanical merging. Many definitions that are | |
| 168 | identical between the two are still found in both versions. | |
| 169 | ||
| 170 | The first version, with BFD_ASSEMBLER defined, uses high-level BFD | |
| 171 | interfaces and data structures. The second version, with | |
| 172 | BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping | |
| 173 | data structures and for doing the actual I/O. The latter defines | |
| 174 | the preprocessor symbols BFD and BFD_HEADERS. Try not to let this | |
| 175 | confuse you. | |
| 176 | ||
| 177 | These two are in the process of being merged, and eventually the | |
| 178 | BFD_ASSEMBLER version should take over completely. Release timing | |
| 179 | issues and namespace problems convinced me to merge the two | |
| 180 | together in this fashion, a little sooner than I would have liked. | |
| 181 | The real merge should be much better done by the time the next | |
| 182 | release comes out. | |
| 183 | ||
| 184 | For now, the structure of this file is: | |
| 185 | <common> | |
| 186 | #ifdef BFD_ASSEMBLER | |
| 187 | <one version> | |
| 188 | #else | |
| 189 | <other version> | |
| 190 | #endif | |
| 191 | <common> | |
| 192 | Unfortunately, the common portions are very small at the moment, | |
| 193 | and many declarations or definitions are duplicated. The structure | |
| 194 | of obj-coff.c is similar. | |
| 195 | ||
| 196 | See doc/internals.texi for a brief discussion of the history, if | |
| 197 | you care. | |
