Targets
|
||
|
||
DESCRIPTION
|
||
Each port of BFD to a different machine requires the creation
|
||
of a target back end. All the back end provides to the root
|
||
part of BFD is a structure containing pointers to functions
|
||
which perform certain low level operations on files. BFD
|
||
translates the applications's requests through a pointer into
|
||
calls to the back end routines.
|
||
|
||
When a file is opened with <<bfd_openr>>, its format and
|
||
target are unknown. BFD uses various mechanisms to determine
|
||
how to interpret the file. The operations performed are:
|
||
|
||
o Create a BFD by calling the internal routine
|
||
<<_bfd_new_bfd>>, then call <<bfd_find_target>> with the
|
||
target string supplied to <<bfd_openr>> and the new BFD pointer.
|
||
|
||
o If a null target string was provided to <<bfd_find_target>>,
|
||
look up the environment variable <<GNUTARGET>> and use
|
||
that as the target string.
|
||
|
||
o If the target string is still <<NULL>>, or the target string is
|
||
<<default>>, then use the first item in the target vector
|
||
as the target type, and set <<target_defaulted>> in the BFD to
|
||
cause <<bfd_check_format>> to loop through all the targets.
|
||
@xref{bfd_target}. @xref{Formats}.
|
||
|
||
o Otherwise, inspect the elements in the target vector
|
||
one by one, until a match on target name is found. When found,
|
||
use it.
|
||
|
||
o Otherwise return the error <<bfd_error_invalid_target>> to
|
||
<<bfd_openr>>.
|
||
|
||
o <<bfd_openr>> attempts to open the file using
|
||
<<bfd_open_file>>, and returns the BFD.
|
||
|
||
Once the BFD has been opened and the target selected, the file
|
||
format may be determined. This is done by calling
|
||
<<bfd_check_format>> on the BFD with a suggested format.
|
||
If <<target_defaulted>> has been set, each possible target
|
||
type is tried to see if it recognizes the specified format.
|
||
<<bfd_check_format>> returns <<TRUE>> when the caller guesses right.

bfd_target
|
||
|
||
DESCRIPTION
|
||
This structure contains everything that BFD knows about a
|
||
target. It includes things like its byte order, name, and which
|
||
routines to call to do various operations.
|
||
|
||
Every BFD points to a target structure with its <<xvec>>
|
||
member.
|
||
|
||
The macros below are used to dispatch to functions through the
|
||
<<bfd_target>> vector. They are used in a number of macros further
|
||
down in @file{bfd.h}, and are also used when calling various
|
||
routines by hand inside the BFD implementation. The @var{arglist}
|
||
argument must be parenthesized; it contains all the arguments
|
||
to the called function.
|
||
|
||
They make the documentation (more) unpleasant to read, so if
|
||
someone wants to fix this and not break the above, please do.
|
||
|
||
.#define BFD_SEND(bfd, message, arglist) \
|
||
. ((*((bfd)->xvec->message)) arglist)
|
||
.
|
||
.#ifdef DEBUG_BFD_SEND
|
||
.#undef BFD_SEND
|
||
.#define BFD_SEND(bfd, message, arglist) \
|
||
. (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
|
||
. ((*((bfd)->xvec->message)) arglist) : \
|
||
. (bfd_assert (__FILE__,__LINE__), NULL))
|
||
.#endif
|
||
|
||
For operations which index on the BFD format:
|
||
|
||
.#define BFD_SEND_FMT(bfd, message, arglist) \
|
||
. (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist)
|
||
.
|
||
.#ifdef DEBUG_BFD_SEND
|
||
.#undef BFD_SEND_FMT
|
||
.#define BFD_SEND_FMT(bfd, message, arglist) \
|
||
. (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \
|
||
. (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \
|
||
. (bfd_assert (__FILE__,__LINE__), NULL))
|
||
.#endif
|
||
.
|
||
This is the structure which defines the type of BFD this is. The
|
||
<<xvec>> member of the struct <<bfd>> itself points here. Each
|
||
module that implements access to a different target under BFD,
|
||
defines one of these.
|
||
|
||
FIXME, these names should be rationalised with the names of
|
||
the entry points which call them. Too bad we can't have one
|
||
macro to define them both!
