24/* This structure contains everything that BFD knows about a target.
25 It includes things like its byte order, name, what routines to call
26 to do various operations, etc. Every BFD points to a target structure
27 with its "xvec" member.
28
29 There are two such structures here: one for big-endian machines and
30 one for little-endian machines. */
