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
	Coff long section names

	In the standard Coff object format, section names are limited to
	the eight bytes available in the @code{s_name} field of the
	@code{SCNHDR} section header structure.  The format requires the
	field to be NUL-padded, but not necessarily NUL-terminated, so
	the longest section names permitted are a full eight characters.

	The Microsoft PE variants of the Coff object file format add
	an extension to support the use of long section names.  This
	extension is defined in section 4 of the Microsoft PE/COFF
	specification (rev 8.1).  If a section name is too long to fit
	into the section header's @code{s_name} field, it is instead
	placed into the string table, and the @code{s_name} field is
	filled with a slash ("/") followed by the ASCII decimal
	representation of the offset of the full name relative to the
	string table base.

	Note that this implies that the extension can only be used in object
	files, as executables do not contain a string table.  The standard
	specifies that long section names from objects emitted into executable
	images are to be truncated.

	However, as a GNU extension, BFD can generate executable images
	that contain a string table and long section names.  This
	would appear to be technically valid, as the standard only says
	that Coff debugging information is deprecated, not forbidden,
	and in practice it works, although some tools that parse PE files
	expecting the MS standard format may become confused; @file{PEview} is
	one known example.

	The functionality is supported in BFD by code implemented under
	the control of the macro @code{COFF_LONG_SECTION_NAMES}.  If not
	defined, the format does not support long section names in any way.
	If defined, it is used to initialise a flag,
	@code{_bfd_coff_long_section_names}, and a hook function pointer,
	@code{_bfd_coff_set_long_section_names}, in the Coff backend data
	structure.  The flag controls the generation of long section names
	in output BFDs at runtime; if it is false, as it will be by default
	when generating an executable image, long section names are truncated;
	if true, the long section names extension is employed.  The hook
	points to a function that allows the value of the flag to be altered
	at runtime, on formats that support long section names at all; on
	other formats it points to a stub that returns an error indication.

	With input BFDs, the flag is set according to whether any long section
	names are detected while reading the section headers.  For a completely
	new BFD, the flag is set to the default for the target format.  This
	information can be used by a client of the BFD library when deciding
	what output format to generate, and means that a BFD that is opened
	for read and subsequently converted to a writeable BFD and modified
	in-place will retain whatever format it had on input.

	If @code{COFF_LONG_SECTION_NAMES} is simply defined (blank), or is
	defined to the value "1", then long section names are enabled by
	default; if it is defined to the value zero, they are disabled by
	default (but still accepted in input BFDs).  The header @file{coffcode.h}
	defines a macro, @code{COFF_DEFAULT_LONG_SECTION_NAMES}, which is
	used in the backends to initialise the backend data structure fields
	appropriately; see the comments for further detail.

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_lineno_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 hierarchy 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 linenumbers

	Creating the linenumber table is done by reading in the entire
	coff linenumber table, and creating another table for internal use.

	A coff linenumber table is structured so that each function
	is marked as having a line number of 0. Each line within the
	function is an offset from the first line in the function. The
	base of the line number information for the table is stored in
	the symbol associated with the function.

	Note: The PE format uses line number 0 for a flag indicating a
	new source file.

	The information is copied from the external to the internal
	table, and each symbol which marks a function is marked by
	pointing its...

	How does this work ?

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.
