  39. DESCRIPTION
  40.         Each port of BFD to a different machine requires the creation
  41.         of a target back end. All the back end provides to the root
  42.         part of BFD is a structure containing pointers to functions
  43.         which perform certain low level operations on files. BFD
  44.         translates the applications's requests through a pointer into
  45.         calls to the back end routines.
  46.  
  47.         When a file is opened with <<bfd_openr>>, its format and
  48.         target are unknown. BFD uses various mechanisms to determine
  49.         how to interpret the file. The operations performed are:
  50.  
  51.         o Create a BFD by calling the internal routine
  52.         <<_bfd_new_bfd>>, then call <<bfd_find_target>> with the
  53.         target string supplied to <<bfd_openr>> and the new BFD pointer.
  54.  
  55.         o If a null target string was provided to <<bfd_find_target>>,
  56.         look up the environment variable <<GNUTARGET>> and use
  57.         that as the target string.
  58.  
  59.         o If the target string is still <<NULL>>, or the target string is
  60.         <<default>>, then use the first item in the target vector
  61.         as the target type, and set <<target_defaulted>> in the BFD to
  62.         cause <<bfd_check_format>> to loop through all the targets.
  63.         @xref{bfd_target}.  @xref{Formats}.
  64.  
  65.         o Otherwise, inspect the elements in the target vector
  66.         one by one, until a match on target name is found. When found,
  67.         use it.
  68.  
  69.         o Otherwise return the error <<bfd_error_invalid_target>> to
  70.         <<bfd_openr>>.
  71.  
  72.         o <<bfd_openr>> attempts to open the file using
  73.         <<bfd_open_file>>, and returns the BFD.
  74.  
  75.         Once the BFD has been opened and the target selected, the file
  76.         format may be determined. This is done by calling
  77.         <<bfd_check_format>> on the BFD with a suggested format.
  78.         If <<target_defaulted>> has been set, each possible target
  79.         type is tried to see if it recognizes the specified format.
  80.         <<bfd_check_format>> returns <<TRUE>> when the caller guesses right.

  92.         bfd_target
  93.  
  94. DESCRIPTION
  95.         This structure contains everything that BFD knows about a
  96.         target. It includes things like its byte order, name, and which
  97.         routines to call to do various operations.
  98.  
  99.         Every BFD points to a target structure with its <<xvec>>
  100.         member.
  101.  
  102.         The macros below are used to dispatch to functions through the
  103.         <<bfd_target>> vector. They are used in a number of macros further
  104.         down in @file{bfd.h}, and are also used when calling various
  105.         routines by hand inside the BFD implementation.  The @var{arglist}
  106.         argument must be parenthesized; it contains all the arguments
  107.         to the called function.
  108.  
  109.         They make the documentation (more) unpleasant to read, so if
  110.         someone wants to fix this and not break the above, please do.
  111.  
  112. .#define BFD_SEND(bfd, message, arglist) \
  113. .  ((*((bfd)->xvec->message)) arglist)
  114. .
  115. .#ifdef DEBUG_BFD_SEND
  116. .#undef BFD_SEND
  117. .#define BFD_SEND(bfd, message, arglist) \
  118. .  (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
  119. .    ((*((bfd)->xvec->message)) arglist) : \
  120. .    (bfd_assert (__FILE__,__LINE__), NULL))
  121. .#endif
  122.  
  123.         For operations which index on the BFD format:
  124.  
  125. .#define BFD_SEND_FMT(bfd, message, arglist) \
  126. .  (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)

  128. .#ifdef DEBUG_BFD_SEND
  129. .#undef BFD_SEND_FMT
  130. .#define BFD_SEND_FMT(bfd, message, arglist) \
  131. .  (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
  132. .   (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
  133. .   (bfd_assert (__FILE__,__LINE__), NULL))
  134. .#endif
  135. .
  136.         This is the structure which defines the type of BFD this is.  The
  137.         <<xvec>> member of the struct <<bfd>> itself points here.  Each
  138.         module that implements access to a different target under BFD,
  139.         defines one of these.
  140.  
  141.         FIXME, these names should be rationalised with the names of
  142.         the entry points which call them. Too bad we can't have one
  143.         macro to define them both!
