* aoutx.h, coffgen.c, ecoff.c, ecofflink.c, elf.c, libbfd.c, linker.c, reloc.c, section.c, srec.c: Added /*ARGSUSED*/ as appropriate. * aoutx.h (struct external_exec): Removed unnecessary declaration.

DESCRIPTION
|
||
These macros as used for reading and writing raw data in
|
||
sections; each access (except for bytes) is vectored through
|
||
the target format of the BFD and mangled accordingly. The
|
||
mangling performs any necessary endian translations and
|
||
removes alignment restrictions. Note that types accepted and
|
||
returned by these macros are identical so they can be swapped
|
||
around in macros---for example, @file{libaout.h} defines <<GET_WORD>>
|
||
to either <<bfd_get_32>> or <<bfd_get_64>>.
|
||
|
||
In the put routines, @var{val} must be a <<bfd_vma>>. If we are on a
|
||
system without prototypes, the caller is responsible for making
|
||
sure that is true, with a cast if necessary. We don't cast
|
||
them in the macro definitions because that would prevent <<lint>>
|
||
or <<gcc -Wall>> from detecting sins such as passing a pointer.
|
||
To detect calling these with less than a <<bfd_vma>>, use
|
||
<<gcc -Wconversion>> on a host with 64 bit <<bfd_vma>>'s.
