-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.
