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

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