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

61DESCRIPTION
62	This enum gives the object file's CPU architecture, in a
63	global sense---i.e., what processor family does it belong to?
64	Another field indicates which processor within
65	the family is in use.  The machine gives a number which
66	distinguishes different versions of the architecture,
67	containing, for example, 2 and 3 for Intel i960 KA and i960 KB,
68	and 68020 and 68030 for Motorola 68020 and 68030.
