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 | |
0ef5a5bd | 35 | <<bfd_arch_info_type>>. |
252b5132 RH |
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 | |
0ef5a5bd | 45 | defined, then all the architectures supported are included. |
252b5132 RH |
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 | |
0ef5a5bd | 51 | default case (an item with a machine field of 0). |
252b5132 RH |
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, | |
0ef5a5bd | 68 | and 68020 and 68030 for Motorola 68020 and 68030. |
