This is normally set up in the 44 @file{config/@var{target}.mt} file of your choice. If the name is not 45 defined, then all the architectures supported are included. 46 47 When BFD starts up, all the architectures are called with an 48 initialize method. It is up to the architecture back end to 49 insert as many items into the list of architectures as it wants to; 50 generally this would be one for each machine and one for the 51 default case (an item with a machine field of 0). 52 53 BFD's idea of an architecture is implemented in @file{archures.c}. 54*/ 55 56/* 57 58SUBSECTION 59 bfd_architecture 60 61DESCRIPTION 62 This enum gives the object file's CPU architecture, in a 63 global sense---i.e., what processor family does it belong to? 64 Another field indicates which processor within 65 the family is in use. The machine gives a number which 66 distinguishes different versions of the architecture, 67 containing, for example, 2 and 3 for Intel i960 KA and i960 KB, 68 and 68020 and 68030 for Motorola 68020 and 68030. 69 70.enum bfd_architecture 71.{ 72. bfd_arch_unknown, {* File arch not known. *} 73. bfd_arch_obscure, {* Arch known, not one of these. *} 74. bfd_arch_m68k, {* Motorola 68xxx *} 75.#define bfd_mach_m68000 1 76.#define bfd_mach_m68008 2 77.#define bfd_mach_m68010 3 78.#define bfd_mach_m68020 4 79.#define bfd_mach_m68030 5 80.#define bfd_mach_m68040 6 81.#define bfd_mach_m68060 7 82.#define bfd_mach_cpu32 8 83.#define bfd_mach_mcf5200 9 84.#define bfd_mach_mcf5206e 10 85.#define bfd_mach_mcf5307 11 86.#define bfd_mach_mcf5407 12 87.#define bfd_mach_mcf528x 13 88. bfd_arch_vax, {* DEC Vax *} 89. bfd_arch_i960, {* Intel 960 *} 90. {* The order of the following is important. 91. lower number indicates a machine type that 92. only accepts a subset of the instructions 93. available to machines with higher numbers. 94.
