---|
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.
|
---|

|
---|
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!
