DESCRIPTION
41
  Each port of BFD to a different machine requires the creation
42
  of a target back end. All the back end provides to the root
43
  part of BFD is a structure containing pointers to functions
44
  which perform certain low level operations on files. BFD
45
  translates the applications's requests through a pointer into
46
  calls to the back end routines.
47
48
  When a file is opened with <<bfd_openr>>, its format and
49
  target are unknown. BFD uses various mechanisms to determine
50
  how to interpret the file. The operations performed are:
51
52
  o Create a BFD by calling the internal routine
53
  <<_bfd_new_bfd>>, then call <<bfd_find_target>> with the
54
  target string supplied to <<bfd_openr>> and the new BFD pointer.
55
56
  o If a null target string was provided to <<bfd_find_target>>,
57
  look up the environment variable <<GNUTARGET>> and use
58
  that as the target string.
59
60
  o If the target string is still <<NULL>>, or the target string is
61
  <<default>>, then use the first item in the target vector
62
  as the target type, and set <<target_defaulted>> in the BFD to
63
  cause <<bfd_check_format>> to loop through all the targets.
64
  @xref{bfd_target}.  @xref{Formats}.
65
66
  o Otherwise, inspect the elements in the target vector
67
  one by one, until a match on target name is found. When found,
68
  use it.
69
70
  o Otherwise return the error <<bfd_error_invalid_target>> to
71
  <<bfd_openr>>.
72
73
  o <<bfd_openr>> attempts to open the file using
74
  <<bfd_open_file>>, and returns the BFD.
75
76
  Once the BFD has been opened and the target selected, the file
77
  format may be determined. This is done by calling
78
  <<bfd_check_format>> on the BFD with a suggested format.
79
  If <<target_defaulted>> has been set, each possible target
80
  type is tried to see if it recognizes the specified format.
81
  <<bfd_check_format>> returns <<TRUE>> when the caller guesses right.

DESCRIPTION
96
  This structure contains everything that BFD knows about a
97
  target. It includes things like its byte order, name, and which
98
  routines to call to do various operations.
99
100
  Every BFD points to a target structure with its <<xvec>>
101
  member.
102
103
  The macros below are used to dispatch to functions through the
104
  <<bfd_target>> vector. They are used in a number of macros further
105
  down in @file{bfd.h}, and are also used when calling various
106
  routines by hand inside the BFD implementation.  The @var{arglist}
107
  argument must be parenthesized; it contains all the arguments
108
  to the called function.
109
110
  They make the documentation (more) unpleasant to read, so if
111
  someone wants to fix this and not break the above, please do.

125
126

127
.  (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)

142
  This is the structure which defines the type of BFD this is.  The
143
  <<xvec>> member of the struct <<bfd>> itself points here.  Each
144
  module that implements access to a different target under BFD,
145
  defines one of these.
146
147
  FIXME, these names should be rationalised with the names of
148
  the entry points which call them. Too bad we can't have one
149
  macro to define them both!

DESCRIPTION
1629
  Return a pointer to the transfer vector for the object target
1630
  named @var{target_name}.  If @var{target_name} is <<NULL>>,
1631
  choose the one in the environment variable <<GNUTARGET>>; if
1632
  that is null or not defined, then choose the first entry in the
1633
  target list.  Passing in the string "default" or setting the
1634
  environment variable to "default" will cause the first entry in
1635
  the target list to be returned, and "target_defaulted" will be
1636
  set in the BFD if @var{abfd} isn't <<NULL>>.  This causes
1637
  <<bfd_check_format>> to loop over all the targets to find the
1638
  one that matches the file being read.
1639
  If @var{is_bigendian} is not <<NULL>>, then set this value to target's
1640
  endian mode. True for big-endian, FALSE for little-endian or for
1641
  invalid target.
1642
  If @var{underscoring} is not <<NULL>>, then set this value to target's
1643
  underscoring mode. Zero for none-underscoring, -1 for invalid target,
1644
  else the value of target vector's symbol underscoring.
1645
  If @var{def_target_arch} is not <<NULL>>, then set it to the architecture
1646
  string specified by the target_name.
