The MIPS assembly idiom 'move' now maps to the 'or' machine instruction. This change affects microMIPS, MIPS32, MIPS64. 2015-08-12 Simon Dardis <simon.dardis@imgtec.com> opcodes/ * micromips-opc.c (micromips_opcodes): Re-order table so that move based on 'or' is first. * mips-opc.c (mips_builtin_opcodes): Ditto. bfd/ * elfxx-mips.c (STUB_MOVE): Change to use 'or' only. (mips_o32_exec_plt0_entry, mips_n32_exec_plt0_entry, mips_n64_exec_plt0_entry, micromips_insn32_o32_exec_plt0_entry): Update to use 'or' instead of 'addu/daddu'. (_bfd_mips_elf_finish_dynamic_symbol): Update usage of STUB_MOVE. (move_insns_32): Reorder table. gas/ * config/tc-mips.c (move_register): Change to use 'or' only. (s_cpload, s_cpsetup, s_cprestore, s_cpreturn): Update to use or for move. gas/testsuite/ * gas/mips/elf-rel23.d: Update test. * gas/mips/elf-rel23.d: Ditto. * gas/mips/elf-rel23a.d: Ditto. * gas/mips/elf-rel23b.d: Ditto. * gas/mips/elf_e_flags1.d: Ditto. * gas/mips/elf_e_flags2.d: Ditto. * gas/mips/elf_e_flags3.d: Ditto. * gas/mips/elf_e_flags4.d: Ditto. * gas/mips/loc-swap-dis.d: Ditto. * gas/mips/micromips-insn32.d: Ditto. * gas/mips/micromips-noinsn32.d: Ditto. * gas/mips/micromips-trap.d: Ditto. * gas/mips/micromips.d: Ditto. * gas/mips/mips-abi32-pic.d: Ditto. * gas/mips/mips-abi32.d: Ditto. * gas/mips/mips-gp32-fp32-pic.d: Ditto. * gas/mips/mips-gp32-fp32.d: Ditto. * gas/mips/mips-gp32-fp64-pic.d: Ditto. * gas/mips/mips-gp32-fp64.d: Ditto. * gas/mips/mips-gp64-fp32-pic.d: Ditto. * gas/mips/mips-gp64-fp32.d: Ditto. * gas/mips/mips-gp64-fp64-pic.d: Ditto. * gas/mips/mips-gp64-fp64.d: Ditto. * gas/mips/mipsr6@loc-swap-dis.d: Ditto. * gas/mips/tls-o32.d: Ditto. * gas/mips/uld2-eb.d: Ditto. * gas/mips/uld2-el.d: Ditto. * gas/mips/ulw2-eb-ilocks.d: Ditto. * gas/mips/ulw2-eb.d: Ditto. * gas/mips/ulw2-el-ilocks.d: Ditto. * gas/mips/ulw2-el.d: Ditto. * gas/mips/move.d: New test. * gas/mips/move.s: Ditto. * gas/mips/micromips32-move.d: Ditto. * gas/mips/micromips32-move.s: Ditto. * gas/mips/mips.exp: Run the new tests. gold/ * mips.cc (plt0_entry_o32, plt0_entry_n32, plt0_entry_n64, lazy_stub_normal_1, lazy_stub_normal_1_n64, lazy_stub_normal_2, lazy_stub_normal_2_n64, lazy_stub_big, lazy_stub_big_n64, lazy_stub_micromips32_normal_1_n64, lazy_stub_micromips32_normal_2_n64, lazy_stub_micromips32_big, lazy_stub_micromips32_big_n64): Update to use 'or' for move instead of 'addu/daddu'. ld/testsuite/ * ld-mips-elf/compressed-plt-1-n32-mips16.od: Update test. * ld-mips-elf/compressed-plt-1-n32-umips.od: Ditto. * ld-mips-elf/compressed-plt-1-o32-mips16-got.od: Ditto. * ld-mips-elf/compressed-plt-1-o32-mips16-only.od: Ditto. * ld-mips-elf/compressed-plt-1-o32-mips16-word.od: Ditto. * ld-mips-elf/compressed-plt-1-o32-mips16.od: Ditto. * ld-mips-elf/compressed-plt-1-o32-se.od: Ditto. * ld-mips-elf/compressed-plt-1-o32-umips-got.od: Ditto. * ld-mips-elf/compressed-plt-1-o32-umips-word.od: Ditto. * ld-mips-elf/compressed-plt-1-o32-umips.od: Ditto. * ld-mips-elf/jalx-2.dd: Ditto. * ld-mips-elf/mips16-pic-3.dd: Ditto. * ld-mips-elf/pic-and-nonpic-3a.dd: Ditto. * ld-mips-elf/pic-and-nonpic-3b.dd: Ditto. * ld-mips-elf/pic-and-nonpic-5b.dd: Ditto. * ld-mips-elf/pic-and-nonpic-6-n32.dd: Ditto. * ld-mips-elf/pic-and-nonpic-6-o32.dd: Ditto. * ld-mips-elf/stub-dynsym-1-10000.d: Ditto. * ld-mips-elf/stub-dynsym-1-2fe80.d: Ditto. * ld-mips-elf/stub-dynsym-1-7fff.d: Ditto. * ld-mips-elf/stub-dynsym-1-8000.d: Ditto. * ld-mips-elf/stub-dynsym-1-fff0.d: Ditto. * ld-mips-elf/tlsbin-o32.d: Ditto. * ld-mips-elf/tlsdyn-o32-1.d: Ditto. * ld-mips-elf/tlsdyn-o32-2.d: Ditto. * ld-mips-elf/tlsdyn-o32-3.d: Ditto. * ld-mips-elf/tlsdyn-o32.d: Ditto. * ld-mips-elf/tlslib-o32.d: Ditto.
