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

| DESCRIPTION |
| This enum gives the object file's CPU architecture, in a |
| global sense---i.e., what processor family does it belong to? |
| Another field indicates which processor within |
| the family is in use. The machine gives a number which |
| distinguishes different versions of the architecture, |
| containing, for example, 2 and 3 for Intel i960 KA and i960 KB, |
| and 68020 and 68030 for Motorola 68020 and 68030. |
