SUBSECTION
- How The Coff Backend Works
+ How the coff backend works
+
+SUBSUBSECTION
+ File layout
+
+ The Coff backend is split into generic routines that are
+ applicable to any Coff target and routines that are specific
+ to a particular target. The target-specific routines are
+ further split into ones which are basically the same for all
+ Coff targets except that they use the external symbol format
+ or use different values for certain constants.
+
+ The generic routines are in @file{coffgen.c}. These routines
+ work for any Coff target. They use some hooks into the target
+ specific code; the hooks are in a @code{bfd_coff_backend_data}
+ structure, one of which exists for each target.
+
+ The essentially similar target-specific routines are in
+ @file{coffcode.h}. This header file includes executable C code.
+ The various Coff targets first include the appropriate Coff
+ header file, make any special defines that are needed, and
+ then include @file{coffcode.h}.
+
+ Some of the Coff targets then also have additional routines in
+ the target source file itself.
+
+ For example, @file{coff-i960.c} includes
+ @file{coff/internal.h} and @file{coff/i960.h}. It then
+ defines a few constants, such as @code{I960}, and includes
+ @file{coffcode.h}. Since the i960 has complex relocation
+ types, @file{coff-i960.c} also includes some code to
+ manipulate the i960 relocs. This code is not in
+ @file{coffcode.h} because it would not be used by any other
+ target.

@code{bfd_swap}_@i{thing}_@i{direction} routines. Some
elements are different sizes between different versions of

correct one. No doubt, some day someone will find a version of

@code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track
of all the symbol table and reloc drudgery itself, thereby
saving the internal BFD overhead, but uses BFD to swap things
