/* 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.
