141 This file really contains two implementations of the COFF back end.
142 They are in the process of being merged, but this is only a
143 preliminary, mechanical merging. Many definitions that are
144 identical between the two are still found in both versions.
146 The first version, with BFD_ASSEMBLER defined, uses high-level BFD
147 interfaces and data structures. The second version, with
148 BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping
149 data structures and for doing the actual I/O. The latter defines
150 the preprocessor symbols BFD and BFD_HEADERS. Try not to let this
153 These two are in the process of being merged, and eventually the
154 BFD_ASSEMBLER version should take over completely. Release timing
155 issues and namespace problems convinced me to merge the two
156 together in this fashion, a little sooner than I would have liked.
157 The real merge should be much better done by the time the next
160 For now, the structure of this file is:
168 Unfortunately, the common portions are very small at the moment,
169 and many declarations or definitions are duplicated. The structure
170 of obj-coff.c is similar.
