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.
