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. | |||
