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

SUBSECTION
bfd_architecture
DESCRIPTION
This enum gives the object file's CPU architecture, in a
global sense---i.e., what processor family does it belong to?
Another field indicates which processor within
the family is in use. The machine gives a number which
distinguishes different versions of the architecture,
containing, for example, 68020 for Motorola 68020.
