     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.
