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 57SUBSECTION 58 bfd_architecture 59 60DESCRIPTION 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, 68020 for Motorola 68020. 67 68.enum bfd_architecture 69.{ 70. bfd_arch_unknown, {* File arch not known. *} 71. bfd_arch_obscure, {* Arch known, not one of these. *} 72. bfd_arch_m68k, {* Motorola 68xxx. *} 73.#define bfd_mach_m68000 1 74.#define bfd_mach_m68008 2 75.#define bfd_mach_m68010 3 76.#define bfd_mach_m68020 4 77.#define bfd_mach_m68030 5 78.#define bfd_mach_m68040 6 79.#define bfd_mach_m68060 7 80.#define bfd_mach_cpu32 8 81.#define bfd_mach_fido 9 82.#define bfd_mach_mcf_isa_a_nodiv 10 83.#define bfd_mach_mcf_isa_a 11 84.#define bfd_mach_mcf_isa_a_mac 12 85.#define bfd_mach_mcf_isa_a_emac 13 86.#define bfd_mach_mcf_isa_aplus 14 87.#define bfd_mach_mcf_isa_aplus_mac 15 88.#define bfd_mach_mcf_isa_aplus_emac 16 89.#define bfd_mach_mcf_isa_b_nousp 17 90.#define bfd_mach_mcf_isa_b_nousp_mac 18 91.#define bfd_mach_mcf_isa_b_nousp_emac 19 92.#define bfd_mach_mcf_isa_b 20 93.#define bfd_mach_mcf_isa_b_mac 21 94.#define bfd_mach_mcf_isa_b_emac 22 95.#define bfd_mach_mcf_isa_b_float 23 96.#define bfd_mach_mcf_isa_b_float_mac 24 97.#define bfd_mach_mcf_isa_b_float_emac 25 98.#define bfd_mach_mcf_isa_c 26 99.#define bfd_mach_mcf_isa_c_mac 27 100.#define bfd_mach_mcf_isa_c_emac 28 101.#define bfd_mach_mcf_isa_c_nodiv 29 102.#define bfd_mach_mcf_isa_c_nodiv_mac 30 103.#define bfd_mach_mcf_isa_c_nodiv_emac 31 104. bfd_arch_vax, {* DEC Vax. *} 105. 106. bfd_arch_or1k, {* OpenRISC 1000. *} 107.#define bfd_mach_or1k 1 108.#define bfd_mach_or1knd 2 109. 110. bfd_arch_sparc, {* SPARC. *} 111.#define bfd_mach_sparc 1 112.{* The difference between v8plus and v9 is that v9 is a true 64 bit env. *} 113.#define bfd_mach_sparc_sparclet 2 114.#define bfd_mach_sparc_sparclite 3 115.#define bfd_mach_sparc_v8plus 4 116.#define bfd_mach_sparc_v8plusa 5 {* with ultrasparc add'ns. *} 117.#define bfd_mach_sparc_sparclite_le 6 118.#define bfd_mach_sparc_v9 7 119.#define bfd_mach_sparc_v9a 8 {* with ultrasparc add'ns. *} 120.#define bfd_mach_sparc_v8plusb 9 {* with cheetah add'ns. *} 121.#define bfd_mach_sparc_v9b 10 {* with cheetah add'ns. *} 122.#define bfd_mach_sparc_v8plusc 11 {* with UA2005 and T1 add'ns. *} 123.#define bfd_mach_sparc_v9c 12 {* with UA2005 and T1 add'ns. *} 124.#define bfd_mach_sparc_v8plusd 13 {* with UA2007 and T3 add'ns. *} 125.#define bfd_mach_sparc_v9d 14 {* with UA2007 and T3 add'ns. *} 126.#define bfd_mach_sparc_v8pluse 15 {* with OSA2001 and T4 add'ns (no IMA). *} 127.#define bfd_mach_sparc_v9e 16 {* with OSA2001 and T4 add'ns (no IMA). *} 128.#define bfd_mach_sparc_v8plusv 17 {* with OSA2011 and T4 and IMA and FJMAU add'ns. *} 129.#define bfd_mach_sparc_v9v 18 {* with OSA2011 and T4 and IMA and FJMAU add'ns. *} 130.#define bfd_mach_sparc_v8plusm 19 {* with OSA2015 and M7 add'ns. *} 131.#define bfd_mach_sparc_v9m 20 {* with OSA2015 and M7 add'ns. *} 132.#define bfd_mach_sparc_v8plusm8 21 {* with OSA2017 and M8 add'ns. *} 133.#define bfd_mach_sparc_v9m8 22 {* with OSA2017 and M8 add'ns. *} 134.{* Nonzero if MACH has the v9 instruction set. *} 135.#define bfd_mach_sparc_v9_p(mach) \ 136.
