This is normally set up in the 43 @file{config/@var{target}.mt} file of your choice. If the name is not 44 defined, then all the architectures supported are included. 45 46 When BFD starts up, all the architectures are called with an 47 initialize method. It is up to the architecture back end to 48 insert as many items into the list of architectures as it wants to; 49 generally this would be one for each machine and one for the 50 default case (an item with a machine field of 0). 51 52 BFD's idea of an architecture is implemented in @file{archures.c}. 53 */ 54 55 /* 56 57 SUBSECTION 58 bfd_architecture 59 60 DESCRIPTION 61 This enum gives the object file's CPU architecture, in a 62 global sense---i.e., what processor family does it belong to? 63 Another field indicates which processor within 64 the family is in use. The machine gives a number which 65 distinguishes different versions of the architecture, 66 containing, for example, 2 and 3 for Intel i960 KA and i960 KB, 67 and 68020 and 68030 for Motorola 68020 and 68030. 68 69 .enum bfd_architecture 70 .{ 71 . bfd_arch_unknown, {* File arch not known. *} 72 . bfd_arch_obscure, {* Arch known, not one of these. *} 73 . bfd_arch_m68k, {* Motorola 68xxx *} 74 .#define bfd_mach_m68000 1 75 .#define bfd_mach_m68008 2 76 .#define bfd_mach_m68010 3 77 .#define bfd_mach_m68020 4 78 .#define bfd_mach_m68030 5 79 .#define bfd_mach_m68040 6 80 .#define bfd_mach_m68060 7 81 .#define bfd_mach_cpu32 8 82 .#define bfd_mach_fido 9 83 .#define bfd_mach_mcf_isa_a_nodiv 10 84 .#define bfd_mach_mcf_isa_a 11 85 .#define bfd_mach_mcf_isa_a_mac 12 86 .#define bfd_mach_mcf_isa_a_emac 13 87 .#define bfd_mach_mcf_isa_aplus 14 88 .#define bfd_mach_mcf_isa_aplus_mac 15 89 .#define bfd_mach_mcf_isa_aplus_emac 16 90 .#define bfd_mach_mcf_isa_b_nousp 17 91 .#define bfd_mach_mcf_isa_b_nousp_mac 18 92 .#define bfd_mach_mcf_isa_b_nousp_emac 19 93 .#define bfd_mach_mcf_isa_b 20 94 .#define bfd_mach_mcf_isa_b_mac 21 95 .#define bfd_mach_mcf_isa_b_emac 22 96 .#define bfd_mach_mcf_isa_b_float 23 97 .#define bfd_mach_mcf_isa_b_float_mac 24 98 .#define bfd_mach_mcf_isa_b_float_emac 25 99 .#define bfd_mach_mcf_isa_c 26 100 .#define bfd_mach_mcf_isa_c_mac 27 101 .#define bfd_mach_mcf_isa_c_emac 28 102 .#define bfd_mach_mcf_isa_c_nodiv 29 103 .#define bfd_mach_mcf_isa_c_nodiv_mac 30 104 .#define bfd_mach_mcf_isa_c_nodiv_emac 31 105 . bfd_arch_vax, {* DEC Vax *} 106 . bfd_arch_i960, {* Intel 960 *} 107 . {* The order of the following is important. 108 . lower number indicates a machine type that 109 . only accepts a subset of the instructions 110 . available to machines with higher numbers. 111 .
