448b8ca865 S12Z: Don't crash when disassembling invalid instructions. 
Check for null before dereferencing an operand pointer.  Normally
this situation should never arise, but could happen if a "partial"
instruction is encountered at the end of a file or section.

opcodes/
	* s12z-dis.c (print_insn_s12z):  Do not dereference an
	operand if it is null.

opcodes/
	* s12z-dis.c (opr_emit_disassembly): Do not omit an index if it is
	zero.

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.

2d5d5a8f0a Include bfd_stdint.h in bfd.h 
This patch adds bfd_stdint.h to bfd.h, so that BFD can use size_t
where appropriate in function parameters and return values.  I also
tidy a few other cases where headers are included twice.

27f42a4ddb S12Z opcodes: Fix bug disassembling certain shift instructions. 
Shift and rotate instructions when the number of bit positions
was an immediate value greater than 1 were incorrectly disassembled.
This change fixes that problem and extends the test to check for
it.

gas/ChangeLog:

  testsuite/gas/s12z/shift.s: Add new test case.
  testsuite/gas/s12z/shift.d: Add expected result.

opcodes/ChangeLog:

  s12z-dis.c (print_insn_shift) [SB_REG_REG_N]: Enter special case
  if the postbyte matches the appropriate pattern.

f41078422a Opcodes: (BRCLR / BRSET) Disassemble reserved codes instead of aborting. 
Bit manipulation instructions which are not normally generated by the
assembler, should nevertheless be decoded by the disassembler.

	BM_RESERVED0 like BM_REG_IMM.

which for versions of GCC before 4.8 prevent support for S12Z targets
from being built.  See also GCC PR c/53066.
