+/* ***********************************************************************
+
+ 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.
