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 | ||
41 | o First a BFD is created by calling the internal routine | |
42 | <<new_bfd>>, then <<bfd_find_target>> is called with the | |
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>>, | |
46 | it looks up the environment variable <<GNUTARGET>> and uses | |
47 | that as the target string. | |
48 | ||
49 | o If the target string is still NULL, or the target string is | |
50 | <<default>>, then the first item in the target vector is used | |
218ce930 JG |
51 | as the target type, and <<target_defaulted>> is set to |
52 | cause <<bfd_check_format>> to loop through all the targets. | |
53 | @xref{bfd_target}. @xref{Formats}. | |
0cda46cf SC |
54 | |
55 | o Otherwise, the elements in the target vector are inspected | |
56 | one by one, until a match on target name is found. When found, | |
57 | that is used. | |
58 | ||
59 | o Otherwise the error <<invalid_target>> is returned to | |
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 | |
69 | type is tried to see if it recognizes the specified format. The | |
0cda46cf | 70 | routine returns <<true>> when the application guesses right. |

e98e6ec1 | 85 | DESCRIPTION |
0cda46cf SC |
86 | This structure contains everything that BFD knows about a |
87 | target. It includes things like its byte order, name, what | |
88 | routines to call to do various operations, etc. | |
6f715d66 | 89 | |
0cda46cf SC |
90 | Every BFD points to a target structure with its <<xvec>> |
91 | member. | |
6f715d66 | 92 | |
0cda46cf SC |
93 | These macros 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 "arglist" | |
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 | |

104 | . ((*((bfd)->xvec->message)) arglist) | |
6f715d66 | 105 | |
0cda46cf | 106 | For operations which index on the BFD format |

109 | . (((bfd)->xvec->message[(int)((bfd)->format)]) arglist) | |
6f715d66 | 110 | |
0cda46cf SC |
111 | This is the struct which defines the type of BFD this is. The |
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. | |

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! | |

543 | ||
544 | DESCRIPTION | |
545 | Returns a pointer to the transfer vector for the object target | |
546 | named target_name. If target_name is NULL, chooses the one in | |
547 | the environment variable GNUTARGET; if that is null or not | |
548 | defined thenthe first entry in the target list is chosen. | |
549 | Passing in the string "default" or setting the environment | |
550 | variable to "default" will cause the first entry in the target | |
551 | list to be returned, and "target_defaulted" will be set in the | |
552 | BFD. This causes <<bfd_check_format>> to loop over all the | |
553 | targets to find the one that matches the file being read. | |
