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.
