        Targets

DESCRIPTION

        Each port of BFD to a different machine requries 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.

SUBSECTION

        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!
