opcodes/
* ppc-dis.c (powerpc_init_dialect): Do not choose a default dialect
due to -many/-Many.
(print_insn_powerpc): Make sure we only deprecate instructions using
the original dialect and not a modified dialect due to -Many handling.
Move the handling of the condition register and default operands to
the end of the if/else if/else chain.
* ppc-opc.c (powerpc_opcodes): Reorder the opcode table so that
instructions from newer processors are listed before older ones.
<"icblce", "sync", "eieio", "tlbld">: Deprecate for processors
that have instructions with conflicting opcodes.
