30 Targets

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

87 DESCRIPTION
88 This structure contains everything that BFD knows about a
89 target. It includes things like its byte order, name, and which
90 routines to call to do various operations.
91
92 Every BFD points to a target structure with its <<xvec>>
93 member.
94
95 The macros below are used to dispatch to functions through the
96 <<bfd_target>> vector. They are used in a number of macros further
97 down in @file{bfd.h}, and are also used when calling various
98 routines by hand inside the BFD implementation. The @var{arglist}
99 argument must be parenthesized; it contains all the arguments
100 to the called function.
101
102 They make the documentation (more) unpleasant to read, so if
103 someone wants to fix this and not break the above, please do.
104
105 .#define BFD_SEND(bfd, message, arglist) \
106 . ((*((bfd)->xvec->message)) arglist)
107 .
108 .#ifdef DEBUG_BFD_SEND
109 .#undef BFD_SEND
110 .#define BFD_SEND(bfd, message, arglist) \
111 . (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
112 . ((*((bfd)->xvec->message)) arglist) : \
113 . (bfd_assert (__FILE__,__LINE__), NULL))
114 .#endif
115
116 For operations which index on the BFD format:
117
118 .#define BFD_SEND_FMT(bfd, message, arglist) \
119 . (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)
120 .
121 .#ifdef DEBUG_BFD_SEND
122 .#undef BFD_SEND_FMT
123 .#define BFD_SEND_FMT(bfd, message, arglist) \
124 . (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
125 . (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
126 . (bfd_assert (__FILE__,__LINE__), NULL))
127 .#endif
128 .
129 This is the structure which defines the type of BFD this is. The
130 <<xvec>> member of the struct <<bfd>> itself points here. Each
131 module that implements access to a different target under BFD,
132 defines one of these.
133
134 FIXME, these names should be rationalised with the names of
135 the entry points which call them. Too bad we can't have one
136 macro to define them both!

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