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