This file is part of BFD, the Binary File Descriptor library.
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
+ example, the i386 coff format is implemented in the file
+ @file{coff-i386.c}. This file @code{#include}s
+ @file{coff/i386.h} which defines the external structure of the
+ coff format for the i386, and @file{coff/internal.h} which
+ defines the internal structure. @file{coff-i386.c} also
+ defines the relocations used by the i386 coff 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
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.
