30 | Targets |
31 | ||
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 | |
5bff4f56 | 38 | calls to the back end routines. |
252b5132 RH |
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 | |
5bff4f56 | 46 | target string supplied to <<bfd_openr>> and the new BFD pointer. |
252b5132 RH |
47 | |
48 | o If a null target string was provided to <<bfd_find_target>>, | |
49 | look up the environment variable <<GNUTARGET>> and use | |
5bff4f56 | 50 | that as the target string. |
252b5132 RH |
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, | |
5bff4f56 | 60 | use it. |
252b5132 RH |
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 | |
5bff4f56 | 70 | <<bfd_check_format>> on the BFD with a suggested format. |
252b5132 RH |
71 | If <<target_defaulted>> has been set, each possible target |
72 | type is tried to see if it recognizes the specified format. | |
b34976b6 | 73 | <<bfd_check_format>> returns <<TRUE>> when the caller guesses right. |

85 | bfd_target | |
86 | ||
87 | DESCRIPTION | |
88 | This structure contains everything that BFD knows about a | |
89 | target. It includes things like its byte order, name, and which | |
5bff4f56 | 90 | routines to call to do various operations. |
252b5132 RH |
91 | |
92 | Every BFD points to a target structure with its <<xvec>> | |
5bff4f56 | 93 | member. |
252b5132 RH |
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 | |
5bff4f56 | 100 | to the called function. |
252b5132 RH |
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. | |

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 | ||
252b5132 RH |
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 | |
5bff4f56 | 136 | macro to define them both! |
