        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}.

DESCRIPTION
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.
