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
0ef5a5bd 34 <<bfd_arch_info_type>>.
252b5132
RH		 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
0ef5a5bd 44 defined, then all the architectures supported are included.
252b5132
RH		 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
0ef5a5bd 50 default case (an item with a machine field of 0).
252b5132
RH		 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,
0ef5a5bd 67 and 68020 and 68030 for Motorola 68020 and 68030.

999 Return the number of octets (8-bit quantities) per target byte
1000 (minimum addressable unit). In most cases, this will be one, but some
1001 DSP targets have 16, 32, or even 48 bits per byte.
