e98e6ec1 | 29 | DESCRIPTION |
0cda46cf SC |
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. | |
36 | ||
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: | |
40 | ||
c188b0be DM |
41 | o Create a BFD by calling the internal routine |
42 | <<new_bfd>>, then call <<bfd_find_target>> with the | |
0cda46cf SC |
43 | target string supplied to <<bfd_openr>> and the new BFD pointer. |
44 | ||
45 | o If a null target string was provided to <<bfd_find_target>>, | |
c188b0be | 46 | look up the environment variable <<GNUTARGET>> and use |
0cda46cf SC |
47 | that as the target string. |
48 | ||
49 | o If the target string is still NULL, or the target string is | |
c188b0be DM |
50 | <<default>>, then use the first item in the target vector |
51 | as the target type, and set <<target_defaulted>> in the BFD to | |
218ce930 JG |
52 | cause <<bfd_check_format>> to loop through all the targets. |
53 | @xref{bfd_target}. @xref{Formats}. | |
0cda46cf | 54 | |
c188b0be | 55 | o Otherwise, inspect the elements in the target vector |
0cda46cf | 56 | one by one, until a match on target name is found. When found, |
c188b0be | 57 | use it. |
0cda46cf | 58 | |
c188b0be | 59 | o Otherwise return the error <<invalid_target>> to |
0cda46cf SC |
60 | <<bfd_openr>>. |
61 | ||
62 | o <<bfd_openr>> attempts to open the file using | |
63 | <<bfd_open_file>>, and returns the BFD. | |
64 | ||
65 | Once the BFD has been opened and the target selected, the file | |
66 | format may be determined. This is done by calling | |
218ce930 JG |
67 | <<bfd_check_format>> on the BFD with a suggested format. |
68 | If <<target_defaulted>> has been set, each possible target | |
c188b0be DM |
69 | type is tried to see if it recognizes the specified format. |
70 | <<bfd_check_format>> returns <<true>> when the caller guesses right. | |

e98e6ec1 | 85 | DESCRIPTION |
0cda46cf | 86 | This structure contains everything that BFD knows about a |
c188b0be DM |
87 | target. It includes things like its byte order, name, and which |
88 | routines to call to do various operations. | |
6f715d66 | 89 | |
0cda46cf SC |
90 | Every BFD points to a target structure with its <<xvec>> |
91 | member. | |
6f715d66 | 92 | |
c188b0be DM |
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 | |
0cda46cf | 95 | down in @file{bfd.h}, and are also used when calling various |
c188b0be | 96 | routines by hand inside the BFD implementation. The @var{arglist} |
0cda46cf SC |
97 | argument must be parenthesized; it contains all the arguments |
98 | to the called function. | |
6f715d66 | 99 | |
ce07dd7c KR |
100 | They make the documentation (more) unpleasant to read, so if |
101 | someone wants to fix this and not break the above, please do. | |
6f715d66 | 102 | |
0cda46cf SC |
103 | .#define BFD_SEND(bfd, message, arglist) \ |
104 | . ((*((bfd)->xvec->message)) arglist) | |
6f715d66 | 105 | |
c188b0be | 106 | For operations which index on the BFD format: |
6f715d66 | 107 | |
0cda46cf SC |
108 | .#define BFD_SEND_FMT(bfd, message, arglist) \ |
109 | . (((bfd)->xvec->message[(int)((bfd)->format)]) arglist) | |
6f715d66 | 110 | |
c188b0be | 111 | This is the structure which defines the type of BFD this is. The |
0cda46cf SC |
112 | <<xvec>> member of the struct <<bfd>> itself points here. Each |
113 | module that implements access to a different target under BFD, | |
114 | defines one of these. | |
6f715d66 | 115 | |
6f715d66 | 116 | |
0cda46cf SC |
117 | FIXME, these names should be rationalised with the names of |
118 | the entry points which call them. Too bad we can't have one | |
119 | macro to define them both! | |
