-@section coff backends
-
-BFD supports a number of different flavours of coff format. The major
-difference between formats are the sizes and alignments of fields in
-structures on disk, and the occasional extra field.
-
-Coff in all its varieties is implimented with a few common files and a
-number of implementation specific files. For example, The 88k bcs coff
-format is implemented in the file @code{m88k-bcs.c}. This file
-@code{#include}s @code{m88k-bcs.h} which defines the external
-structure of the coff format for the 88k, and @code{internalcoff.h}
-which defines the internal structure. @code{m88k-bcs.c} also defines
-the relocations used by the 88k format @xref{Relocations}. Then the
-major portion of coff code is included (@code{coffcode.h}) which
-defines the methods used to act upon the types defined in
-@code{m88k-bcs.h} and @code{internalcoff.h}.
-
-The Intel i960 processor version of coff is implemented in
-@code{icoff.c}. This file has the same structure as
-@code{m88k-bcs.c}, except that it includes @code{intel-coff.h} rather
-than @code{m88k-bcs.h}.
-
-@subsection Porting To A New Version of Coff
-
-The recommended method is to select from the existing implimentations
-the version of coff which is most like the one you want to use, for
-our purposes, we'll say that i386 coff is the one you select, and that
-your coff flavour is called foo. Copy the @code{i386coff.c} to @code{foocoff.c},
-copy @code{../include/i386coff.h} to @code{../include/foocoff.h} and
-add the lines to @code{targets.c} and @code{Makefile.in} so that your
-new back end is used.
-
-Alter the shapes of the structures in @code{../include/foocoff.h} so
-that they match what you need. You will probably also have to add
-@code{#ifdef}s to the code in @code{internalcoff.h} and
-@code{coffcode.h} if your version of coff is too wild.
-
-You can verify that your new BFD backend works quite simply by
-building @code{objdump} from the @code{binutils} directory, and
-making sure that its version of what's going on at your host systems
-idea (assuming it has the pretty standard coff dump utility (usually
-called @code{att-dump} or just @code{dump})) are the same.
-
-Then clean up your code, and send what you've done to Cygnus. Then your stuff
-will be in the next release, and you won't have to keep integrating
-it.
-
-@subsection How The Coff Backend Works
-
-@subsubsection Bit Twiddling
-Each flavour of coff supported in BFD has its own header file
-descibing the external layout of the structures. There is also an
-internal description of the coff layout (in @code{internalcoff.h})
-file (@code{}). A major function of the coff backend is swapping the
-bytes and twiddling the bits to translate the external form of the
-structures into the normal internal form. This is all performed in the
-@code{bfd_swap}_@i{thing}_@i{direction} routines. Some elements are
-different sizes between different versions of coff, it is the duty of
-the coff version specific include file to override the definitions of
-various packing routines in @code{coffcode.h}. Eg the size of line
-number entry in coff is sometimes 16 bits, and sometimes 32 bits.
-@code{#define}ing @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will
-select the correct one. No doubt, some day someone will find a version
-of coff which has a varying field size not catered for at the moment.
-To port BFD, that person will have to add more @code{#defines}.
-
-Three of the bit twiddling routines are exported to @code{gdb};
-@code{coff_swap_aux_in}, @code{coff_swap_sym_in} and
-@code{coff_swap_linno_in}. @code{GDB} reads the symbol table on its
-own, but uses BFD to fix things up.
-
-More of the bit twiddlers are exported for @code{gas};
-@code{coff_swap_aux_out}, @code{coff_swap_sym_out},
-@code{coff_swap_lineno_out}, @code{coff_swap_reloc_out},
-@code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out},
-@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 on the way out,
-making cross ports much safer. This also allows BFD (and thus the
-linker) to use the same header files as @code{gas}, which makes one
-avenue to disaster disappear.
-
-@subsubsection Symbol Reading
-The simple canonical form for symbols used by BFD is not rich enough
-to keep all the information available in a coff symbol table. The back
-end gets around this by keeping the original symbol table around,
-"behind the scenes".
-
-When a symbol table is requested (through a call to
-@code{bfd_canonicalize_symtab}, a request gets through to
-@code{get_normalized_symtab}. This reads the symbol table from the
-coff file and swaps all the structures inside into the internal form.
-It also fixes up all the pointers in the table (represented in the file
-by offsets from the first symbol in the table) into physical pointers
-to elements in the new internal table. This involves some work since
-the meanings of fields changes depending upon context; a field that is a
-pointer to another structure in the symbol table at one moment may be
-the size in bytes of a structure in the next.
-
-Another pass is made over the table. All symbols which mark file names
-(@code{C_FILE} symbols) are modified so that the internal string
-points to the value in the auxent (the real filename) rather than the
-normal text associated with the symbol (@code{".file"}).
-
-At this time the symbol names are moved around. Coff stores all
-symbols less than nine characters long physically within the symbol
-table, longer strings are kept at the end of the file in the string
-table. This pass moves all strings into memory, and replaces them with
-pointers to the strings.
-
-The symbol table is massaged once again, this time to create the
-canonical table used by the BFD application. Each symbol is inspected
-in turn, and a decision made (using the @code{sclass} field) about the
-various flags to set in the @code{asymbol} @xref{Symbols}. The
-generated canonical table shares strings with the hidden internal
-symbol table.
-
-Any linenumbers are read from the coff file too, and attached to the
-symbols which own the functions the linenumbers belong to.
-
-@subsubsection Symbol Writing
-Writing a symbol to a coff file which didn't come from a coff file
-will lose any debugging information. The @code{asymbol} structure
-remembers the BFD from which was born, and on output the back end
-makes sure that the same destination target as source target is
-present.
-
-When the symbols have come from a coff file then all the debugging
-information is preserved.
-
-Symbol tables are provided for writing to the back end in a vector of
-pointers to pointers. This allows applications like the linker to
-accumulate and output large symbol tables without having to do too
-much byte copying.
-
-The symbol table is not output to a writable BFD until it is closed.
-The order of operations on the canonical symbol table at that point
-are:
-@table @code
-@item coff_renumber_symbols
-This function runs through the provided symbol table and patches each
-symbol marked as a file place holder (@code{C_FILE}) to point to the
-next file place holder in the list. It also marks each @code{offset}
-field in the list with the offset from the first symbol of the current
-symbol.
-
-Another function of this procedure is to turn the canonical value form
-of BFD into the form used by coff. Internally, BFD expects symbol
-values to be offsets from a section base; so a symbol physically at
-0x120, but in a section starting at 0x100, would have the value 0x20.
-Coff expects symbols to contain their final value, so symbols have
-their values changed at this point to reflect their sum with their
-owning section. Note that this transformation uses the
-@code{output_section} field of the @code{asymbol}'s @code{asection}
-@xref{Sections}.
-@item coff_mangle_symbols
-This routine runs though the provided symbol table and uses the
-offsets generated by the previous pass and the pointers generated when
-the symbol table was read in to create the structured hierachy
-required by coff. It changes each pointer to a symbol to an index into
-the symbol table of the symbol being referenced.
-@item coff_write_symbols
-This routine runs through the symbol table and patches up the symbols
-from their internal form into the coff way, calls the bit twiddlers
-and writes out the tabel to the file.

+SUBSECTION
+ 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.
+
+SUBSUBSECTION
+ Bit twiddling
+
+ Each flavour of coff supported in BFD has its own header file
+ describing the external layout of the structures. There is also
+ an internal description of the coff layout, in
+ @file{coff/internal.h}. A major function of the
+ coff backend is swapping the bytes and twiddling the bits to
+ translate the external form of the structures into the normal
+ internal form. This is all performed in the
+ @code{bfd_swap}_@i{thing}_@i{direction} routines. Some
+ elements are different sizes between different versions of
+ coff; it is the duty of the coff version specific include file
+ to override the definitions of various packing routines in
+ @file{coffcode.h}. E.g., the size of line number entry in coff is
+ sometimes 16 bits, and sometimes 32 bits. @code{#define}ing
+ @code{PUT_LNSZ_LNNO} and @code{GET_LNSZ_LNNO} will select the
+ correct one. No doubt, some day someone will find a version of
+ coff which has a varying field size not catered to at the
+ moment. To port BFD, that person will have to add more @code{#defines}.
+ Three of the bit twiddling routines are exported to
+ @code{gdb}; @code{coff_swap_aux_in}, @code{coff_swap_sym_in}
+ and @code{coff_swap_linno_in}. @code{GDB} reads the symbol
+ table on its own, but uses BFD to fix things up. More of the
+ bit twiddlers are exported for @code{gas};
+ @code{coff_swap_aux_out}, @code{coff_swap_sym_out},
+ @code{coff_swap_lineno_out}, @code{coff_swap_reloc_out},
+ @code{coff_swap_filehdr_out}, @code{coff_swap_aouthdr_out},
+ @code{coff_swap_scnhdr_out}. @code{Gas} currently keeps track
