/* ***********************************************************************
This file really contains two implementations of the COFF back end.
They are in the process of being merged, but this is only a
preliminary, mechanical merging. 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. The structure
of obj-coff.c is similar.
See doc/internals.texi for a brief discussion of the history, if
you care.
