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.

SUBSUBSECTION
Coff long section names
The Microsoft PE variants of the Coff object file format add
an extension to support the use of long section names. This
- extension is defined in section 4 of the Microsoft PE/COFF
+ extension is defined in section 4 of the Microsoft PE/COFF
specification (rev 8.1). If a section name is too long to fit
into the section header's @code{s_name} field, it is instead
placed into the string table, and the @code{s_name} field is
- filled with a slash ("/") followed by the ASCII decimal
+ filled with a slash ("/") followed by the ASCII decimal
representation of the offset of the full name relative to the
string table base.
expecting the MS standard format may become confused; @file{PEview} is
one known example.
- The functionality is supported in BFD by code implemented under
+ The functionality is supported in BFD by code implemented under
the control of the macro @code{COFF_LONG_SECTION_NAMES}. If not
defined, the format does not support long section names in any way.
- If defined, it is used to initialise a flag,
- @code{_bfd_coff_long_section_names}, and a hook function pointer,
+ If defined, it is used to initialise a flag,
+ @code{_bfd_coff_long_section_names}, and a hook function pointer,
@code{_bfd_coff_set_long_section_names}, in the Coff backend data
structure. The flag controls the generation of long section names
in output BFDs at runtime; if it is false, as it will be by default
points to a function that allows the value of the flag to be altered
at runtime, on formats that support long section names at all; on
other formats it points to a stub that returns an error indication.
-
+
With input BFDs, the flag is set according to whether any long section
names are detected while reading the section headers. For a completely
new BFD, the flag is set to the default for the target format. This
