| 36 | SECTION |
| 37 | Targets |
| 38 | |
| 39 | DESCRIPTION |
| 40 | Each port of BFD to a different machine requires the creation |
| 41 | of a target back end. All the back end provides to the root |
| 42 | part of BFD is a structure containing pointers to functions |
| 43 | which perform certain low level operations on files. BFD |
| 44 | translates the applications's requests through a pointer into |
| 45 | calls to the back end routines. |
| 46 | |
| 47 | When a file is opened with <<bfd_openr>>, its format and |
| 48 | target are unknown. BFD uses various mechanisms to determine |
| 49 | how to interpret the file. The operations performed are: |
| 50 | |
| 51 | o Create a BFD by calling the internal routine |
| 52 | <<_bfd_new_bfd>>, then call <<bfd_find_target>> with the |
| 53 | target string supplied to <<bfd_openr>> and the new BFD pointer. |
| 54 | |
| 55 | o If a null target string was provided to <<bfd_find_target>>, |
| 56 | look up the environment variable <<GNUTARGET>> and use |
| 57 | that as the target string. |
| 58 | |
| 59 | o If the target string is still <<NULL>>, or the target string is |
| 60 | <<default>>, then use the first item in the target vector |
| 61 | as the target type, and set <<target_defaulted>> in the BFD to |
| 62 | cause <<bfd_check_format>> to loop through all the targets. |
| 63 | @xref{bfd_target}. @xref{Formats}. |
| 64 | |
| 65 | o Otherwise, inspect the elements in the target vector |
| 66 | one by one, until a match on target name is found. When found, |
| 67 | use it. |
| 68 | |
| 69 | o Otherwise return the error <<bfd_error_invalid_target>> to |
| 70 | <<bfd_openr>>. |
| 71 | |
| 72 | o <<bfd_openr>> attempts to open the file using |
| 73 | <<bfd_open_file>>, and returns the BFD. |
| 74 | |
| 75 | Once the BFD has been opened and the target selected, the file |
| 76 | format may be determined. This is done by calling |
| 77 | <<bfd_check_format>> on the BFD with a suggested format. |
| 78 | If <<target_defaulted>> has been set, each possible target |
| 79 | type is tried to see if it recognizes the specified format. |
| 80 | <<bfd_check_format>> returns <<TRUE>> when the caller guesses right. |

| 92 | bfd_target |
| 93 | |
| 94 | DESCRIPTION |
| 95 | This structure contains everything that BFD knows about a |
| 96 | target. It includes things like its byte order, name, and which |
| 97 | routines to call to do various operations. |
| 98 | |
| 99 | Every BFD points to a target structure with its <<xvec>> |
| 100 | member. |
| 101 | |
| 102 | The macros below are used to dispatch to functions through the |
| 103 | <<bfd_target>> vector. They are used in a number of macros further |
| 104 | down in @file{bfd.h}, and are also used when calling various |
| 105 | routines by hand inside the BFD implementation. The @var{arglist} |
| 106 | argument must be parenthesized; it contains all the arguments |
| 107 | to the called function. |
| 108 | |
| 109 | They make the documentation (more) unpleasant to read, so if |
| 110 | someone wants to fix this and not break the above, please do. |

| 140 | . |
| 141 | This is the structure which defines the type of BFD this is. The |
| 142 | <<xvec>> member of the struct <<bfd>> itself points here. Each |
| 143 | module that implements access to a different target under BFD, |
| 144 | defines one of these. |
| 145 | |
| 146 | FIXME, these names should be rationalised with the names of |
| 147 | the entry points which call them. Too bad we can't have one |
| 148 | macro to define them both! |

| 1619 | const char **def_target_arch); |
| 1620 | DESCRIPTION |
| 1621 | Return a pointer to the transfer vector for the object target |
| 1622 | named @var{target_name}. If @var{target_name} is <<NULL>>, |
| 1623 | choose the one in the environment variable <<GNUTARGET>>; if |
| 1624 | that is null or not defined, then choose the first entry in the |
| 1625 | target list. Passing in the string "default" or setting the |
| 1626 | environment variable to "default" will cause the first entry in |
| 1627 | the target list to be returned, and "target_defaulted" will be |
| 1628 | set in the BFD if @var{abfd} isn't <<NULL>>. This causes |
| 1629 | <<bfd_check_format>> to loop over all the targets to find the |
| 1630 | one that matches the file being read. |
| 1631 | If @var{is_bigendian} is not <<NULL>>, then set this value to target's |
| 1632 | endian mode. True for big-endian, FALSE for little-endian or for |
| 1633 | invalid target. |
| 1634 | If @var{underscoring} is not <<NULL>>, then set this value to target's |
| 1635 | underscoring mode. Zero for none-underscoring, -1 for invalid target, |
| 1636 | else the value of target vector's symbol underscoring. |
| 1637 | If @var{def_target_arch} is not <<NULL>>, then set it to the architecture |
| 1638 | string specified by the target_name. |
