I think it is past time to remove CR16C support. CR16C was added in 2004, and only for ld. gas and binutils support is lacking, and there have been no commits to bfd/elf32-cr16c.c other than warning fixes or global maintainers making changes to all targets. I see no maintainer listed for CR16C, and no commits from anyone at NSC supporting the target. Furthermore, at the time the CR16 support was added in 2007, config.sub was changed upstream to no longer recognise cr16c as a valid cpu. That means the CR16C ld support is only available as a secondary target by configuring with, for example, --enable-targets=all or --enable-targets=cr16c-unknown-elf. No testing of the CR16C target is possible. include/ * elf/cr16c.h: Delete. bfd/ * cpu-cr16c.c: Delete. * elf32-cr16c.c: Delete. * Makefile.am, * archures.c, * config.bfd, * configure.ac, * reloc.c, * targets.c: Remove cr16c support. * Makefile.in, * bfd-in2.h, * configure, * libbfd.h, * po/SRC-POTFILES.in: Regenerate. ld/ * emulparams/elf32cr16c.sh: Delete. * scripttempl/elf32cr16c.sc: Delete. * Makefile.am, * configure.tgt: Remove cr16c support. * NEWS: Mention removal of cr16c. * Makefile.in, * po/BLD-POTFILES.in: Regenerate.

Targets
|
||
|
||
DESCRIPTION
|
||
Each port of BFD to a different machine requires the creation
|
||
of a target back end. All the back end provides to the root
|
||
part of BFD is a structure containing pointers to functions
|
||
which perform certain low level operations on files. BFD
|
||
translates the applications's requests through a pointer into
|
||
calls to the back end routines.
|
||
|
||
When a file is opened with <<bfd_openr>>, its format and
|
||
target are unknown. BFD uses various mechanisms to determine
|
||
how to interpret the file. The operations performed are:
|
||
|
||
o Create a BFD by calling the internal routine
|
||
<<_bfd_new_bfd>>, then call <<bfd_find_target>> with the
|
||
target string supplied to <<bfd_openr>> and the new BFD pointer.
|
||
|
||
o If a null target string was provided to <<bfd_find_target>>,
|
||
look up the environment variable <<GNUTARGET>> and use
|
||
that as the target string.
|
||
|
||
o If the target string is still <<NULL>>, or the target string is
|
||
<<default>>, then use the first item in the target vector
|
||
as the target type, and set <<target_defaulted>> in the BFD to
|
||
cause <<bfd_check_format>> to loop through all the targets.
|
||
@xref{bfd_target}. @xref{Formats}.
|
||
|
||
o Otherwise, inspect the elements in the target vector
|
||
one by one, until a match on target name is found. When found,
|
||
use it.
|
||
|
||
o Otherwise return the error <<bfd_error_invalid_target>> to
|
||
<<bfd_openr>>.
|
||
|
||
o <<bfd_openr>> attempts to open the file using
|
||
<<bfd_open_file>>, and returns the BFD.
|
||
|
||
Once the BFD has been opened and the target selected, the file
|
||
format may be determined. This is done by calling
|
||
<<bfd_check_format>> on the BFD with a suggested format.
|
||
If <<target_defaulted>> has been set, each possible target
|
||
type is tried to see if it recognizes the specified format.
|
||
<<bfd_check_format>> returns <<TRUE>> when the caller guesses right.

bfd_target
|
||
|
||
DESCRIPTION
|
||
This structure contains everything that BFD knows about a
|
||
target. It includes things like its byte order, name, and which
|
||
routines to call to do various operations.
|
||
|
||
Every BFD points to a target structure with its <<xvec>>
|
||
member.
|
||
|
||
The macros below are used to dispatch to functions through the
|
||
<<bfd_target>> vector. They are used in a number of macros further
|
||
down in @file{bfd.h}, and are also used when calling various
|
||
routines by hand inside the BFD implementation. The @var{arglist}
|
||
argument must be parenthesized; it contains all the arguments
|
||
to the called function.
|
||
|
||
They make the documentation (more) unpleasant to read, so if
|
||
someone wants to fix this and not break the above, please do.
|
||
|
||
.#define BFD_SEND(bfd, message, arglist) \
|
||
. ((*((bfd)->xvec->message)) arglist)
|
||
.
|
||
.#ifdef DEBUG_BFD_SEND
|
||
.#undef BFD_SEND
|
||
.#define BFD_SEND(bfd, message, arglist) \
|
||
. (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
|
||
. ((*((bfd)->xvec->message)) arglist) : \
|
||
. (bfd_assert (__FILE__,__LINE__), NULL))
|
||
.#endif
|
||
|
||
For operations which index on the BFD format:
|
||
|
||
.#define BFD_SEND_FMT(bfd, message, arglist) \
|
||
. (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)
|
||
.
|
||
.#ifdef DEBUG_BFD_SEND
|
||
.#undef BFD_SEND_FMT
|
||
.#define BFD_SEND_FMT(bfd, message, arglist) \
|
||
. (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
|
||
. (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
|
||
. (bfd_assert (__FILE__,__LINE__), NULL))
|
||
.#endif
|
||
.
|
||
This is the structure which defines the type of BFD this is. The
|
||
<<xvec>> member of the struct <<bfd>> itself points here. Each
|
||
module that implements access to a different target under BFD,
|
||
defines one of these.
|
||
|
||
FIXME, these names should be rationalised with the names of
|
||
the entry points which call them. Too bad we can't have one
|
||
macro to define them both!
