	(mips_set_isa_flags): Likewise.
	(mips_mach_extensions): Likewise.
	(bfd_mips_isa_ext_mach): Likewise.
	(bfd_mips_isa_ext): Likewise.
	(print_mips_isa_ext): Delete AFL_EXT_LOONGSON_3A.

binutils/
	* NEWS: Mention Loongson 3A1000 proccessor support.
	* readelf.c (get_machine_flags): Rename loongson-3a to gs464.
	(print_mips_isa_ext): Delete AFL_EXT_LOONGSON_3A.

elfcpp/
	* mips.c (EF_MIPS_MACH): Rename E_MIPS_MACH_LS3A to
	E_MIPS_MACH_GS464.

gas/
	* config/tc-mips.c (ISA_HAS_ODD_SINGLE_FPR): Rename
	CPU_LOONGSON_3A to CPU_GS464.
	(mips_cpu_info_table): Add gs464 descriptors, Keep
	loongson3a as an alias of gs464 for compatibility.
	* doc/as.texi (march table): Rename loongson3a to gs464.
	* testsuite/gas/mips/loongson-3a-mmi.d: Set "ISA Extension"
	flag to None.

gold/
	* mips.cc (Mips_mach, add_machine_extensions, elf_mips_mach):
	Rename loongson3a to gs464.
	(mips_isa_ext_mach, mips_isa_ext): Delete loongson3a.
	(infer_abiflags): Use ases instead of isa_ext for infer ABI
flags.
	(elf_mips_mach_name): Rename loongson3a to gs464.

include/
	* elf/mips.h (E_MIPS_MACH_XXX): Rename E_MIPS_MACH_LS3A to
	E_MIPS_MACH_GS464.
	(AFL_EXT_XXX): Delete AFL_EXT_LOONGSON_3A.
	* opcode/mips.h (INSN_XXX): Delete INSN_LOONGSON_3A.
	(CPU_XXX): Rename CPU_LOONGSON_3A to CPU_GS464.
	* opcode/mips.h (mips_isa_table): Delete CPU_LOONGSON_3A case.

ld/
	* testsuite/ld-mips-elf/mips-elf-flags.exp: Rename loongson3a
	to gs464.

opcodes/
	* mips-dis.c (mips_arch_choices): Add gs464 descriptors, Keep
	loongson3a as an alias of gs464 for compatibility.
	* mips-opc.c (mips_opcodes): Change Comments.
