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

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