  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}.

  61 DESCRIPTION
  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.
