| 38 | SECTION |
| 39 | Targets |
| 40 | |
| 41 | DESCRIPTION |
| 42 | Each port of BFD to a different machine requires the creation |
| 43 | of a target back end. All the back end provides to the root |
| 44 | part of BFD is a structure containing pointers to functions |
| 45 | which perform certain low level operations on files. BFD |
| 46 | translates the applications's requests through a pointer into |
| 47 | calls to the back end routines. |
| 48 | |
| 49 | When a file is opened with <<bfd_openr>>, its format and |
| 50 | target are unknown. BFD uses various mechanisms to determine |
| 51 | how to interpret the file. The operations performed are: |
| 52 | |
| 53 | o Create a BFD by calling the internal routine |
| 54 | <<_bfd_new_bfd>>, then call <<bfd_find_target>> with the |
| 55 | target string supplied to <<bfd_openr>> and the new BFD pointer. |
| 56 | |
| 57 | o If a null target string was provided to <<bfd_find_target>>, |
| 58 | look up the environment variable <<GNUTARGET>> and use |
| 59 | that as the target string. |
| 60 | |
| 61 | o If the target string is still <<NULL>>, or the target string is |
| 62 | <<default>>, then use the first item in the target vector |
| 63 | as the target type, and set <<target_defaulted>> in the BFD to |
| 64 | cause <<bfd_check_format>> to loop through all the targets. |
| 65 | @xref{bfd_target}. @xref{Formats}. |
| 66 | |
| 67 | o Otherwise, inspect the elements in the target vector |
| 68 | one by one, until a match on target name is found. When found, |
| 69 | use it. |
| 70 | |
| 71 | o Otherwise return the error <<bfd_error_invalid_target>> to |
| 72 | <<bfd_openr>>. |
| 73 | |
| 74 | o <<bfd_openr>> attempts to open the file using |
| 75 | <<bfd_open_file>>, and returns the BFD. |
| 76 | |
| 77 | Once the BFD has been opened and the target selected, the file |
| 78 | format may be determined. This is done by calling |
| 79 | <<bfd_check_format>> on the BFD with a suggested format. |
| 80 | If <<target_defaulted>> has been set, each possible target |
| 81 | type is tried to see if it recognizes the specified format. |
| 82 | <<bfd_check_format>> returns <<TRUE>> when the caller guesses right. |

| 94 | bfd_target |
| 95 | |
| 96 | DESCRIPTION |
| 97 | This structure contains everything that BFD knows about a |
| 98 | target. It includes things like its byte order, name, and which |
| 99 | routines to call to do various operations. |
| 100 | |
| 101 | Every BFD points to a target structure with its <<xvec>> |
| 102 | member. |
| 103 | |
| 104 | The macros below are used to dispatch to functions through the |
| 105 | <<bfd_target>> vector. They are used in a number of macros further |
| 106 | down in @file{bfd.h}, and are also used when calling various |
| 107 | routines by hand inside the BFD implementation. The @var{arglist} |
| 108 | argument must be parenthesized; it contains all the arguments |
| 109 | to the called function. |
| 110 | |
| 111 | They make the documentation (more) unpleasant to read, so if |
| 112 | someone wants to fix this and not break the above, please do. |
| 113 | |
| 114 | .#define BFD_SEND(bfd, message, arglist) \ |
| 115 | . ((*((bfd)->xvec->message)) arglist) |
| 116 | . |
| 117 | .#ifdef DEBUG_BFD_SEND |
| 118 | .#undef BFD_SEND |
| 119 | .#define BFD_SEND(bfd, message, arglist) \ |
| 120 | . (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \ |
| 121 | . ((*((bfd)->xvec->message)) arglist) : \ |
| 122 | . (bfd_assert (__FILE__,__LINE__), NULL)) |
| 123 | .#endif |
| 124 | |
| 125 | For operations which index on the BFD format: |
| 126 | |
| 127 | .#define BFD_SEND_FMT(bfd, message, arglist) \ |
| 128 | . (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) |
| 129 | . |
| 130 | .#ifdef DEBUG_BFD_SEND |
| 131 | .#undef BFD_SEND_FMT |
| 132 | .#define BFD_SEND_FMT(bfd, message, arglist) \ |
| 133 | . (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \ |
| 134 | . (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \ |
| 135 | . (bfd_assert (__FILE__,__LINE__), NULL)) |
| 136 | .#endif |
| 137 | . |
| 138 | This is the structure which defines the type of BFD this is. The |
| 139 | <<xvec>> member of the struct <<bfd>> itself points here. Each |
| 140 | module that implements access to a different target under BFD, |
| 141 | defines one of these. |
| 142 | |
| 143 | FIXME, these names should be rationalised with the names of |
| 144 | the entry points which call them. Too bad we can't have one |
| 145 | macro to define them both! |
