+       * ppc-dis.c (ppc_parse_cpu): Add "sticky" param.  Track bits
+       set from ppc_opts.sticky in it.  Delete "retain_mask".
+       (powerpc_init_dialect): Choose default dialect from info->mach
+       before parsing -M options.  Handle more bfd_mach_ppc variants.
+       Update common default to power7.

        * microblaze-opc.h (op_code_struct): Add swapb, swaph Increase MAX_OPCODES.
