opcodes/
* mips-opc.c (mips_builtin_opcodes): Move M_LD_OB and M_SD_OB
macros before their corresponding MIPS III hardware instructions.
gas/
* config/tc-mips.c (macro)[M_LD_OB, M_SD_OB]: Handle 64-bit ABIs.
gas/testsuite/
* gas/mips/lineno.s: Convert to o32.
* gas/mips/lineno.d: Adjust patterns accordingly. Force the o32
ABI.
