| 24 | Architectures |
| 25 | |
| 26 | BFD keeps one atom in a BFD describing the |
| 27 | architecture of the data attached to the BFD: a pointer to a |
| 28 | <<bfd_arch_info_type>>. |
| 29 | |
| 30 | Pointers to structures can be requested independently of a BFD |
| 31 | so that an architecture's information can be interrogated |
| 32 | without access to an open BFD. |
| 33 | |
| 34 | The architecture information is provided by each architecture package. |
| 35 | The set of default architectures is selected by the macro |
| 36 | <<SELECT_ARCHITECTURES>>. This is normally set up in the |
| 37 | @file{config/@var{target}.mt} file of your choice. If the name is not |
| 38 | defined, then all the architectures supported are included. |
| 39 | |
| 40 | When BFD starts up, all the architectures are called with an |
| 41 | initialize method. It is up to the architecture back end to |
| 42 | insert as many items into the list of architectures as it wants to; |
| 43 | generally this would be one for each machine and one for the |
| 44 | default case (an item with a machine field of 0). |
| 45 | |
| 46 | BFD's idea of an architecture is implemented in @file{archures.c}. |

| 56 | global sense---i.e., what processor family does it belong to? |
| 57 | Another field indicates which processor within |
| 58 | the family is in use. The machine gives a number which |
| 59 | distinguishes different versions of the architecture, |
| 60 | containing, for example, 2 and 3 for Intel i960 KA and i960 KB, |
| 61 | and 68020 and 68030 for Motorola 68020 and 68030. |
