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}. 55 */ 56 57 /* 58 59 SUBSECTION 60 bfd_architecture 61 62 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. 70 71 .enum bfd_architecture 72 .{ 73 . bfd_arch_unknown, {* File arch not known. *} 74 . bfd_arch_obscure, {* Arch known, not one of these. *} 75 . bfd_arch_m68k, {* Motorola 68xxx *} 76 .#define bfd_mach_m68000 1 77 .#define bfd_mach_m68008 2 78 .#define bfd_mach_m68010 3 79 .#define bfd_mach_m68020 4 80 .#define bfd_mach_m68030 5 81 .#define bfd_mach_m68040 6 82 .#define bfd_mach_m68060 7 83 .#define bfd_mach_cpu32 8 84 .#define bfd_mach_fido 9 85 .#define bfd_mach_mcf_isa_a_nodiv 10 86 .#define bfd_mach_mcf_isa_a 11 87 .#define bfd_mach_mcf_isa_a_mac 12 88 .#define bfd_mach_mcf_isa_a_emac 13 89 .#define bfd_mach_mcf_isa_aplus 14 90 .#define bfd_mach_mcf_isa_aplus_mac 15 91 .#define bfd_mach_mcf_isa_aplus_emac 16 92 .#define bfd_mach_mcf_isa_b_nousp 17 93 .#define bfd_mach_mcf_isa_b_nousp_mac 18 94 .#define bfd_mach_mcf_isa_b_nousp_emac 19 95 .#define bfd_mach_mcf_isa_b 20 96 .#define bfd_mach_mcf_isa_b_mac 21 97 .#define bfd_mach_mcf_isa_b_emac 22 98 .#define bfd_mach_mcf_isa_b_float 23 99 .#define bfd_mach_mcf_isa_b_float_mac 24 100 .#define bfd_mach_mcf_isa_b_float_emac 25 101 .#define bfd_mach_mcf_isa_c 26 102 .#define bfd_mach_mcf_isa_c_mac 27 103 .#define bfd_mach_mcf_isa_c_emac 28 104 .#define bfd_mach_mcf_isa_c_nodiv 29 105 .#define bfd_mach_mcf_isa_c_nodiv_mac 30 106 .#define bfd_mach_mcf_isa_c_nodiv_emac 31 107 . bfd_arch_vax, {* DEC Vax *} 108 . bfd_arch_i960, {* Intel 960 *} 109 . {* The order of the following is important. 110 . lower number indicates a machine type that 111 . only accepts a subset of the instructions 112 . available to machines with higher numbers. 113 .
