30 Each port of BFD to a different machine requries the creation
31 of a target back end. All the back end provides to the root
32 part of BFD is a structure containing pointers to functions
33 which perform certain low level operations on files. BFD
34 translates the applications's requests through a pointer into
35 calls to the back end routines.
37 When a file is opened with <<bfd_openr>>, its format and
38 target are unknown. BFD uses various mechanisms to determine
39 how to interpret the file. The operations performed are:
41 o Create a BFD by calling the internal routine
42 <<_bfd_new_bfd>>, then call <<bfd_find_target>> with the
43 target string supplied to <<bfd_openr>> and the new BFD pointer.
45 o If a null target string was provided to <<bfd_find_target>>,
46 look up the environment variable <<GNUTARGET>> and use
47 that as the target string.
49 o If the target string is still <<NULL>>, or the target string is
50 <<default>>, then use the first item in the target vector
51 as the target type, and set <<target_defaulted>> in the BFD to
52 cause <<bfd_check_format>> to loop through all the targets.
53 @xref{bfd_target}. @xref{Formats}.
55 o Otherwise, inspect the elements in the target vector
56 one by one, until a match on target name is found. When found,
59 o Otherwise return the error <<bfd_error_invalid_target>> to
62 o <<bfd_openr>> attempts to open the file using
63 <<bfd_open_file>>, and returns the BFD.
65 Once the BFD has been opened and the target selected, the file
66 format may be determined. This is done by calling
67 <<bfd_check_format>> on the BFD with a suggested format.
68 If <<target_defaulted>> has been set, each possible target
69 type is tried to see if it recognizes the specified format.
70 <<bfd_check_format>> returns <<true>> when the caller guesses right.
80 bfd_target, , Targets, Targets
86 This structure contains everything that BFD knows about a
87 target. It includes things like its byte order, name, and which
88 routines to call to do various operations.
90 Every BFD points to a target structure with its <<xvec>>
93 The macros below are used to dispatch to functions through the
94 <<bfd_target>> vector. They are used in a number of macros further
95 down in @file{bfd.h}, and are also used when calling various
96 routines by hand inside the BFD implementation. The @var{arglist}
97 argument must be parenthesized; it contains all the arguments
98 to the called function.
100 They make the documentation (more) unpleasant to read, so if
101 someone wants to fix this and not break the above, please do.
103 .#define BFD_SEND(bfd, message, arglist) \
104 . ((*((bfd)->xvec->message)) arglist)
106 .#ifdef DEBUG_BFD_SEND
108 .#define BFD_SEND(bfd, message, arglist) \
109 . (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
110 . ((*((bfd)->xvec->message)) arglist) : \
111 . (bfd_assert (__FILE__,__LINE__), NULL))
114 For operations which index on the BFD format:
116 .#define BFD_SEND_FMT(bfd, message, arglist) \
117 . (((bfd)->xvec->message[(int)((bfd)->format)]) arglist)
119 .#ifdef DEBUG_BFD_SEND
121 .#define BFD_SEND_FMT(bfd, message, arglist) \
122 . (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
123 . (((bfd)->xvec->message[(int)((bfd)->format)]) arglist) : \
124 . (bfd_assert (__FILE__,__LINE__), NULL))
127 This is the structure which defines the type of BFD this is. The
128 <<xvec>> member of the struct <<bfd>> itself points here. Each
129 module that implements access to a different target under BFD,
130 defines one of these.
133 FIXME, these names should be rationalised with the names of
134 the entry points which call them. Too bad we can't have one
135 macro to define them both!
