/* This structure contains everything that BFD knows about a target.
|
|
|
|
|
It includes things like its byte order, name, what routines to call
|
|
|
|
|
to do various operations, etc. Every BFD points to a target structure
|
|
|
|
|
with its "xvec" member.

There are two such structures here: one for big-endian machines and

one for little-endian machines. */

* targets.c (bfd_target): Rearranged fields in target vector.

rather than the single JUMP_TABLE macro. Removed many of the
weird macro definitions needed to support the monolithic

functions, for use with the new BFD_JUMP_TABLE_* macros.
