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}.

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, 2 and 3 for Intel i960 KA and i960 KB,
|
|
and 68020 and 68030 for Motorola 68020 and 68030.
