Architectures |
| 33 |
|
| 34 |
BFD keeps one atom in a BFD describing the |
| 35 |
architecture of the data attached to the BFD: a pointer to a |
| 36 |
<<bfd_arch_info_type>>. |
| 37 |
|
| 38 |
Pointers to structures can be requested independently of a BFD |
| 39 |
so that an architecture's information can be interrogated |
| 40 |
without access to an open BFD. |
| 41 |
|
| 42 |
The architecture information is provided by each architecture package. |
| 43 |
The set of default architectures is selected by the macro |
| 44 |
<<SELECT_ARCHITECTURES>>. This is normally set up in the |
| 45 |
@file{config/@var{target}.mt} file of your choice. If the name is not |
| 46 |
defined, then all the architectures supported are included. |
| 47 |
|
| 48 |
When BFD starts up, all the architectures are called with an |
| 49 |
initialize method. It is up to the architecture back end to |
| 50 |
insert as many items into the list of architectures as it wants to; |
| 51 |
generally this would be one for each machine and one for the |
| 52 |
default case (an item with a machine field of 0). |
| 53 |
|
| 54 |
BFD's idea of an architecture is implemented in @file{archures.c}. |

DESCRIPTION |
| 63 |
This enum gives the object file's CPU architecture, in a |
| 64 |
global sense---i.e., what processor family does it belong to? |
| 65 |
Another field indicates which processor within |
| 66 |
the family is in use. The machine gives a number which |
| 67 |
distinguishes different versions of the architecture, |
| 68 |
containing, for example, 2 and 3 for Intel i960 KA and i960 KB, |
| 69 |
and 68020 and 68030 for Motorola 68020 and 68030. |
