d87bef3a7b Update year range in copyright notice of binutils files 
The newer update-copyright.py fixes file encoding too, removing cr/lf
on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and
embedded cr in binutils/testsuite/binutils-all/ar.exp string match.

a2c5833233 Update year range in copyright notice of binutils files 
The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.

The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.

d1023b5d1e s12z disassembler tidy 
Don't ignore buffer memory read failure, or malloc failure.  Lots of
functions get a return status to pass these failures up the chain in
this patch.

opcodes/
	* s12z-dis.c (abstract_read_memory): Don't print error on EOI.
	* s12z-opc.c: Formatting.
	(operands_f): Return an int.
	(opr_n_bytes_p1): Return -1 on reaching buffer memory limit.
	(opr_n_bytes2, bfextins_n_bytes, mul_n_bytes, bm_n_bytes),
	(shift_n_bytes, mov_imm_opr_n_bytes, loop_prim_n_bytes),
	(exg_sex_discrim): Likewise.
	(create_immediate_operand, create_bitfield_operand),
	(create_register_operand_with_size, create_register_all_operand),
	(create_register_all16_operand, create_simple_memory_operand),
	(create_memory_operand, create_memory_auto_operand): Don't
	segfault on malloc failure.
	(z_ext24_decode): Return an int status, negative on fail, zero
	on success.
	(x_imm1, imm1_decode, trap_decode, z_opr_decode, z_opr_decode2),
	(imm1234, reg_s_imm, reg_s_opr, z_imm1234_8base, z_imm1234_0base),
	(z_tfr, z_reg, reg_xy, lea_reg_xys_opr, lea_reg_xys, rel_15_7),
	(decode_rel_15_7, cmp_xy, sub_d6_x_y, sub_d6_y_x),
	(ld_18bit_decode, mul_decode, bm_decode, bm_rel_decode),
	(mov_imm_opr, ld_18bit_decode, exg_sex_decode),
	(loop_primitive_decode, shift_decode, psh_pul_decode),
	(bit_field_decode): Similarly.
	(z_decode_signed_value, decode_signed_value): Similarly.  Add arg
	to return value, update callers.
	(x_opr_decode_with_size): Check all reads, returning NULL on fail.
	Don't segfault on NULL operand.
	(decode_operation): Return OP_INVALID on first fail.
	(decode_s12z): Check all reads, returning -1 on fail.

start a line with the name of the function.

ef1ad42b8b S12Z: opcodes: Separate the decoding of operations from their display. 
This change adds an abstraction layer between the decoding of machine
operations and their disassembled textual representation.  This allows
the decoding routines to be re-used for other purposes (at the expense)
of slightly slower running time.

ChangeLog: opcodes/

   * s12z-opc.c: New file.
   * s12z-opc.h: New file.
   * s12z-dis.c: Removed all code not directly related to display
     of instructions.  Used the interface provided by the new files
     instead.
   * Makefile.am (TARGET_LIBOPCODES_CFILES) Add s12z-opc.c.
   * Makefile.in: regenerate.
   * configure.ac (bfd_s12z_arch): Correct the dependencies.
   * configure: regenerate.
