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}.

60DESCRIPTION
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.

481 The <<bfd_default_arch_struct>> is an item of
482 <<bfd_arch_info_type>> which has been initialized to a fairly
483 generic state. A BFD starts life by pointing to this
484 structure, until the correct back end has determined the real
485 architecture of the file.
