+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{coff-m88k.c}. This file @code{#include}s
+ @code{coff-m88k.h} which defines the external structure of the
+ coff format for the 88k, and @code{internalcoff.h} which
+ defines the internal structure. @code{coff-m88k.c} also
+ defines pthe 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{coff-m88k.h} and
+ @code{internalcoff.h}.
+
+
+ The Intel i960 processor version of coff is implemented in
+ @code{coff-i960.c}. This file has the same structure as
+ @code{coff-m88k.c}, except that it includes @code{coff-i960.h}
+ rather than @code{coff-m88k.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
+ (<<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.
+
+ 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
+ <<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 to an index into the symbol table of the symbol
+ being referenced.
+
+ 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 tabel to the file.

+/* run through all the symbols in the symbol table and work out what

-/*
-This procedure runs through the native entries in a coff symbol table
-and links up all the elements which should point to one another, in
-particular these are:
-
-strtag, entag and untags have an auxent endindex which points to the
-first syment after the .eos. This is simple to do, we just keep a
-pointer to the symbol with the most recent pending strtag and patch it
-when we see the eos. This works since coff structs are never nested.
-
-ISFCN type entries have an endindex which points to the next static or
-extern in the table, thereby skipping the function contents.
-The coff book says that an ISFCN's tagindex
-points to the first .bf for the function, so far I havn't seen it
-used. We do this using the same mechanism as strtags.
-
-Each file entry has a value which points to the next file entry,
-the last file entry points to the first extern symbol in the table
-which is not an ISFCN.
-
-Each .bb entry points to the matching .eb entry, but these are nested
-so we keep a stack of them.
-
-The tagndx of .eos items points to the strtag attached to them, this
-is simply the last_tagndx again.
-
-The tagndx of items with type strtag point to the defining struct.
-This bit is complicated; We know that a struct ref and def must be
-within the same file, so all the natives will be in the same vector.
-This means that we can subtracts two pointers and get the index
-differences between to items, used to work out the true index of the
-target.
-
-We store in the name field of each syment the actual native index
-applied so we can dig it out through a pointer. */

+ Reading a coff relocation table is done in the following stages:

+ o The entire coff relocation table is read into memory.
+
+ o Each relocation is processed in turn, first it is swapped from the
+ external to the internal form.
+
+ o The symbol referenced in the relocation's symbol index is
+ turned intoa 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.
+
+ 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.
