This file is part of BFD, the Binary File Descriptor library.
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
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).
