Many definitions that are 201 identical between the two are still found in both versions. 202 203 The first version, with BFD_ASSEMBLER defined, uses high-level BFD 204 interfaces and data structures. The second version, with 205 BFD_ASSEMBLER not defined, also uses BFD, but mostly for swapping 206 data structures and for doing the actual I/O. The latter defines 207 the preprocessor symbols BFD and BFD_HEADERS. Try not to let this 208 confuse you. 209 210 These two are in the process of being merged, and eventually the 211 BFD_ASSEMBLER version should take over completely.
