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

27 There are two such structures here: one for big-endian machines and
28 one for little-endian machines. */
