32 Architectures
33
34 BFD keeps one atom in a BFD describing the
35 architecture of the data attached to the BFD: a pointer to a
36 <<bfd_arch_info_type>>.
37
38 Pointers to structures can be requested independently of a BFD
39 so that an architecture's information can be interrogated
40 without access to an open BFD.
41
42 The architecture information is provided by each architecture package.
43 The set of default architectures is selected by the macro
44 <<SELECT_ARCHITECTURES>>. This is normally set up in the
45 @file{config/@var{target}.mt} file of your choice. If the name is not
46 defined, then all the architectures supported are included.
47
48 When BFD starts up, all the architectures are called with an
49 initialize method. It is up to the architecture back end to
50 insert as many items into the list of architectures as it wants to;
51 generally this would be one for each machine and one for the
52 default case (an item with a machine field of 0).
53
54 BFD's idea of an architecture is implemented in @file{archures.c}.

62DESCRIPTION
63 This enum gives the object file's CPU architecture, in a
64 global sense---i.e., what processor family does it belong to?
65 Another field indicates which processor within
66 the family is in use. The machine gives a number which
67 distinguishes different versions of the architecture,
68 containing, for example, 2 and 3 for Intel i960 KA and i960 KB,
69 and 68020 and 68030 for Motorola 68020 and 68030.
