* Apply these patches from Renesas:
2004-02-10 Kazuhiro Inaoka <inaoka.kazuhiro@renesas.com>
* cpu/m32r.opc (my_print_insn): Fixed incorrect output when
disassembling codes for 0x*2 addresses.
2003-12-15 Kazuhiro Inaoka <inaoka.kazuhiro@renesas.com>
* cpu/m32r.cpu: Add PIPE_O attribute to "pop" instruction.
2003-12-03 Kazuhiro Inaoka <inaoka.kazuhiro@renesas.com>
* cpu/m32r.cpu : Add new model m32r2.
Add new instructions.
Replace occurrances of 'Mitsubishi' with 'Renesas'.
Changed PIPE attr of push from O to OS.
Care for Little-endian of M32R.
* cpu/m32r.opc (CGEN_DIS_HASH, my_print_insn):
Care for Little-endian of M32R.
(parse_slo16): signed extension for value.

appropriate in .cpu files, so it resides here. This especially applies
to assembly/disassembly where parsing/printing can be quite involved.
