SECTION
coff backends
-DESCRIPTION
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
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
+ @code{coff/m88k.h} which defines the external structure of the
+ coff format for the 88k, and @code{coff/internal.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}.
-
+ defines the relocations used by the 88k format
+ @xref{Relocations}.
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}
+ @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
-DESCRIPTION
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}
+ @code{../include/coff/i386.h} to @code{../include/coff/foo.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
+ structures in @code{../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 @code{internalcoff.h} and
+ @code{#ifdef}s to the code in @code{coff/internal.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
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 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
-DESCRIPTION
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
+ @code{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
SUBSUBSECTION
Symbol Reading
-DESCRIPTION
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
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
+ @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
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
+ (<<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"}).
SUBSUBSECTION
Symbol Writing
-
-DESCRIPTION
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 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
@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
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.
