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