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

| 54 | DESCRIPTION |
| 55 | This enum gives the object file's CPU architecture, in a |
| 56 | global sense --- i.e., what processor family does it belong to? |
| 57 | There is another field, which indicates what processor within |
| 58 | the family is in use. The machine gives a number which |
| 59 | distingushes 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. |
