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.

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)
127 .
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!

568 satisfactory. This can happen when the target cpu supports both big
569 and little endian code, and target chosen by the linker has the wrong
570 endianness. The function open_output() in ld/ldlang.c uses this field
571 to find an alternative output format that is suitable.
