+SECTION
+ coff backends
+
+ BFD supports a number of different flavours of coff format.
+ The major differences between formats are the sizes and
+ alignments of fields in structures on disk, and the occasional
+ extra field.
+
+ Coff in all its varieties is implemented with a few common
+ files and a number of implementation specific files. For
+ example, The 88k bcs coff format is implemented in the file
+ @file{coff-m88k.c}. This file @code{#include}s
+ @file{coff/m88k.h} which defines the external structure of the
+ coff format for the 88k, and @file{coff/internal.h} which
+ defines the internal structure. @file{coff-m88k.c} also
+ defines the relocations used by the 88k format
+ @xref{Relocations}.
+
+ The Intel i960 processor version of coff is implemented in
+ @file{coff-i960.c}. This file has the same structure as
+ @file{coff-m88k.c}, except that it includes @file{coff/i960.h}
+ rather than @file{coff-m88k.h}.
+
+SUBSECTION
+ Porting to a new version of coff
+
+ The recommended method is to select from the existing
+ implementations the version of coff which is most like the one
+ you want to use. For example, we'll say that i386 coff is
+ the one you select, and that your coff flavour is called foo.
+ Copy @file{i386coff.c} to @file{foocoff.c}, copy
+ @file{../include/coff/i386.h} to @file{../include/coff/foo.h},
+ and add the lines to @file{targets.c} and @file{Makefile.in}
+ so that your new back end is used. Alter the shapes of the
+ structures in @file{../include/coff/foo.h} so that they match
+ what you need. You will probably also have to add
+ @code{#ifdef}s to the code in @file{coff/internal.h} and
+ @file{coffcode.h} if your version of coff is too wild.
+
+ You can verify that your new BFD backend works quite simply by
+ building @file{objdump} from the @file{binutils} directory,
+ and making sure that its version of what's going on and your
+ host system's 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
+ 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
+ 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. Doing so 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 problem 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{coff_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 change 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 at the next. Another
+ pass is made over the table. All symbols which mark file names
+ (<<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 the symbol was taken, 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.
+
+ 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. This transformation uses the
+ <<output_section>> field of the @code{asymbol}'s
+ @code{asection} @xref{Sections}.
+
+ o <<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 into the index into the symbol table of the asymbol.
+
+ o <<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 table to the file.

+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:
+
+ o Read the entire coff relocation table into memory.
+
+ o Process each relocation in turn; first swap it from the
+ external to the internal form.
+
+ o Turn the symbol referenced in the relocation's symbol index
+ into a pointer into the canonical symbol table.
+ This table is the same as the one returned by a call to
+ @code{bfd_canonicalize_symtab}. The back end will call that
+ routine and save the result if a canonicalization hasn't been done.
+
+ o 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.
