| 198 | /* This file really contains two implementations of the COFF back end. |
| 199 | They are in the process of being merged, but this is only a |
| 200 | preliminary, mechanical merging. Many definitions that are |
| 201 | identical between the two are still found in both versions. |
| 202 | |
| 203 | The first version, with BFD_ASSEMBLER defined, uses high-level BFD |
| 204 | interfaces and data structures. The second version, with |
| 205 | BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping |
| 206 | data structures and for doing the actual I/O. The latter defines |
| 207 | the preprocessor symbols BFD and BFD_HEADERS. Try not to let this |
| 208 | confuse you. |
| 209 | |
| 210 | These two are in the process of being merged, and eventually the |
| 211 | BFD_ASSEMBLER version should take over completely. Release timing |
| 212 | issues and namespace problems convinced me to merge the two |
| 213 | together in this fashion, a little sooner than I would have liked. |
| 214 | The real merge should be much better done by the time the next |
| 215 | release comes out. |

| 221 | #else |
| 222 | <other version> |
| 223 | #endif |
| 224 | <common> |
| 225 | Unfortunately, the common portions are very small at the moment, |
| 226 | and many declarations or definitions are duplicated. The structure |
| 227 | of obj-coff.c is similar. |
| 228 | |
| 229 | See doc/internals.texi for a brief discussion of the history, if |
| 230 | you care. |
