31 | BFD keeps one atom in a BFD describing the |
32 | architecture of the data attached to the BFD: a pointer to a | |
9fda1a39 SC |
33 | <<bfd_arch_info_type>>. |
34 | ||
c188b0be | 35 | Pointers to structures can be requested independently of a BFD |
9fda1a39 | 36 | so that an architecture's information can be interrogated |
c188b0be | 37 | without access to an open BFD. |
9fda1a39 | 38 | |
c188b0be DM |
39 | The architecture information is provided by each architecture package. |
40 | The set of default architectures is selected by the macro | |
9fda1a39 | 41 | <<SELECT_ARCHITECTURES>>. This is normally set up in the |
d94aca1a | 42 | @file{config/@var{target}.mt} file of your choice. If the name is not |
9fda1a39 SC |
43 | defined, then all the architectures supported are included. |
44 | ||
45 | When BFD starts up, all the architectures are called with an | |
46 | initialize method. It is up to the architecture back end to | |
71c0bae0 | 47 | insert as many items into the list of architectures as it wants to; |
9fda1a39 SC |
48 | generally this would be one for each machine and one for the |
49 | default case (an item with a machine field of 0). | |
c188b0be | 50 | |
d94aca1a | 51 | BFD's idea of an architecture is implemented in @file{archures.c}. |

59 | DESCRIPTION | |
60 | This enum gives the object file's CPU architecture, in a | |
c188b0be DM |
61 | global sense---i.e., what processor family does it belong to? |
62 | Another field indicates which processor within | |
9fda1a39 | 63 | the family is in use. The machine gives a number which |
c188b0be DM |
64 | distinguishes different versions of the architecture, |
65 | containing, for example, 2 and 3 for Intel i960 KA and i960 KB, | |
9fda1a39 SC |
66 | and 68020 and 68030 for Motorola 68020 and 68030. |
