195 This file really contains two implementations of the COFF back end.
196 They are in the process of being merged, but this is only a
197 preliminary, mechanical merging. Many definitions that are
198 identical between the two are still found in both versions.
200 The first version, with BFD_ASSEMBLER defined, uses high-level BFD
201 interfaces and data structures. The second version, with
202 BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping
203 data structures and for doing the actual I/O. The latter defines
204 the preprocessor symbols BFD and BFD_HEADERS. Try not to let this
207 These two are in the process of being merged, and eventually the
208 BFD_ASSEMBLER version should take over completely. Release timing
209 issues and namespace problems convinced me to merge the two
210 together in this fashion, a little sooner than I would have liked.
211 The real merge should be much better done by the time the next
214 For now, the structure of this file is:
222 Unfortunately, the common portions are very small at the moment,
223 and many declarations or definitions are duplicated. The structure
224 of obj-coff.c is similar.
