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
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.
