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

+ 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}.

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}.

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
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
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
. {* A pointer to the linenumber information for this symbol *}
.struct lineno_cache_entry *lineno;
.
+. {* Have the line numbers been relocated yet ? *}
+.boolean done_lineno;
