 193 /* This file really contains two implementations of the COFF back end.
 194    They are in the process of being merged, but this is only a
 195    preliminary, mechanical merging.  Many definitions that are
 196    identical between the two are still found in both versions.
 197
 198    The first version, with BFD_ASSEMBLER defined, uses high-level BFD
 199    interfaces and data structures.  The second version, with
 200    BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping
 201    data structures and for doing the actual I/O.  The latter defines
 202    the preprocessor symbols BFD and BFD_HEADERS.  Try not to let this
 203    confuse you.
 204
 205    These two are in the process of being merged, and eventually the
 206    BFD_ASSEMBLER version should take over completely.  Release timing
 207    issues and namespace problems convinced me to merge the two
 208    together in this fashion, a little sooner than I would have liked.
 209    The real merge should be much better done by the time the next
 210    release comes out.
 211
 212    For now, the structure of this file is:
 213         <common>
 214         #ifdef BFD_ASSEMBLER
 215         <one version>
 216         #else
 217         <other version>
 218         #endif
 219         <common>
 220    Unfortunately, the common portions are very small at the moment,
 221    and many declarations or definitions are duplicated.  The structure
 222    of obj-coff.c is similar.
 223
 224    See doc/internals.texi for a brief discussion of the history, if
 225    you care.
