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 <>. 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}. */ /* SUBSECTION bfd_architecture 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. .enum bfd_architecture .{ . bfd_arch_unknown, {* File arch not known *} . bfd_arch_obscure, {* Arch known, not one of these *} . bfd_arch_m68k, {* Motorola 68xxx *} .#define bfd_mach_m68000 1 .#define bfd_mach_m68008 2 .#define bfd_mach_m68010 3 .#define bfd_mach_m68020 4 .#define bfd_mach_m68030 5 .#define bfd_mach_m68040 6 .#define bfd_mach_m68060 7 .#define bfd_mach_cpu32 8 . bfd_arch_vax, {* DEC Vax *} . bfd_arch_i960, {* Intel 960 *} . {* The order of the following is important. . lower number indicates a machine type that . only accepts a subset of the instructions . available to machines with higher numbers. .
