+@section a.out backends
+
+BFD supports a number of different flavours of a.out format, though
+the major differences are only the sizes of the structures on disk,
+and the shape of the relocation information.
+
+The support is split into a basic support file @code{aoutx.h} and
+other files which derive functions from the base. One derivation file
+is @code{aoutf1.h} (for a.out flavour 1), and adds to the basic a.out
+functions support for sun3, sun4, 386 and 29k a.out files, to create a
+target jump vector for a specific target.
+
+This information is further split out into more specific files for each
+machine, including @code{sunos.c} - for sun3 and sun4 and
+@code{demo64} for a demonstration of a 64 bit a.out format.
+
+The base file @code{aoutx.h} defines general mechanisms for reading
+and writing records to and from disk, and various other methods which
+bfd requires. It is included by @code{aout32.c} and @code{aout64.c} to
+form the names aout_32_swap_exec_header_in,
+aout_64_swap_exec_header_in, etc.
+
+As an example, this is what goes on to make the back end for a sun4, from aout32.c
+
+@example
+ #define ARCH_SIZE 32
+ #include "aoutx.h"
+@end example
+
+Which exports names:
+@example
+ ...
+ aout_32_canonicalize_reloc
+ aout_32_find_nearest_line
+ aout_32_get_lineno
+ aout_32_get_reloc_upper_bound
+ ...
+@end example
+
+from sunos.c
+
+@example
+ #define ARCH 32
+ #define TARGET_NAME "a.out-sunos-big"
+ #define VECNAME sunos_big_vec
+ #include "aoutf1.h"
+@end example
+requires all the names from aout32.c, and produces the jump vector
+
+@example
+ sunos_big_vec

+@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.
+
+@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 sceens".
+
+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 attatched 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.
+@end table

+@subsubsection Reading Relocations
+Coff relocations are easily transformed into the internal bfd form
+(@code{arelent}).
+
+Reading a coff relocation table is done in the following stages:
+@itemize @bullet
+@item
+The entire coff relocation table is read into memory.
+@item
+Each relocation is processed in turn, first it is swapped from the
+external to the internal form.
+@item
+The symbol referenced in the relocation's symbol index is turned into
+a pointer into the canonical symbol table. Note that this table is the
+same as the one returned by a call to @code{bfd_canonicalize_symtab}.
+The back end will call the routine and save the result if a
+canonicalization hasn't been done.
+@item
+The reloc index is turned into a pointer to a howto structure, in a
+back end specific way. For instance, the 386 and 960 use the
+@code{r_type} to directly produce an index into a howto table vector;
+the 88k subtracts a number from the @code{r_type} field and creates an
+addend field.

+@section Targets
+Each port of BFD to a different machine requries the creation of a
+target back end. All the back end provides to the root part of bfd is
+a structure containing pointers to functions which perform certain low
+level operations on files. BFD translates the applications's requests
+through a pointer into calls to the back end routines.
+
+When a file is opened with @code{bfd_openr}, its format and target are
+unknown. BFD uses various mechanisms to determine how to interpret the
+file. The operatios performed are:
+@itemize @bullet
+@item
+First a bfd is created by calling the internal routine
+@code{new_bfd}, then @code{bfd_find_target} is called with the target
+string supplied to @code{bfd_openr} and the new bfd pointer.
+@item
+If a null target string was provided to
+@code{bfd_find_target}, it looks up the environment variable
+@code{GNUTARGET} and uses that as the target string.
+@item
+If the target string is still NULL, or the target string
+is @code{default}, then the first item in the target vector is used as
+the target type. @xref{targets}.
+@item
+Otherwise, the elements in the target vector are
+inspected one by one, until a match on target name is found. When
+found, that is used.
+@item
+Otherwise the error @code{invalid_target} is returned to
+@code{bfd_openr}.
+@item
+@code{bfd_openr} attempts to open the file using
+@code{bfd_open_file}, and returns the bfd.
+@end itemize
+Once the bfd has been opened and the target selected, the file format
+may be determined. This is done by calling @code{bfd_check_format} on
+the bfd with a suggested format. The routine returns @code{true} when
+the application guesses right.
+*/
+
+
+/*proto* bfd_target
+@node bfd_target
+@subsection bfd_target
+This structure contains everything that BFD knows about a target.
+It includes things like its byte order, name, what routines to call
+to do various operations, etc.
+
+Every BFD points to a target structure with its "xvec" member.
+
+
+Shortcut for declaring fields which are prototyped function pointers,
+while avoiding anguish on compilers that don't support protos.
+
+$#define SDEF(ret, name, arglist) \
+$ PROTO(ret,(*name),arglist)
+$#define SDEF_FMT(ret, name, arglist) \
+$ PROTO(ret,(*name[bfd_type_end]),arglist)
+
+These macros are used to dispatch to functions through the bfd_target
+vector. They are used in a number of macros further down in bfd.h, and
+are also used when calling various routines by hand inside the bfd
+implementation. The "arglist" argument must be parenthesized; it
+contains all the arguments to the called function.
+
+$#define BFD_SEND(bfd, message, arglist) \
+$ ((*((bfd)->xvec->message)) arglist)
+
+For operations which index on the bfd format
+
+$#define BFD_SEND_FMT(bfd, message, arglist) \
+$ (((bfd)->xvec->message[(int)((bfd)->format)]) arglist)
+
+This is the struct which defines the type of BFD this is. The
+"xvec" member of the struct bfd itself points here. Each module
+that implements access to a different target under BFD, defines
+one of these.
+
+FIXME, these names should be rationalised with the names of the
+entry points which call them. Too bad we can't have one macro to
+define them both!
