+       * rs6000-tdep.c: Changes throughout for multi-arch 64-bit
+       support.  Incorporate most of tm-rs6000.h.
+       (find_toc_address_hook): Rename to rs6000_find_toc_address_hook.
+       (rs6000_set_host_arch_hook): Declare.
+       (read_memory_addr): Define.
+       (pop_frame): Rename to rs6000_pop_frame.
+       (rs6000_pop_frame, rs6000_fix_call_dummy, rs6000_push_arguments,
+       rs6000_frame_saved_pc, rs6000_frame_chain): Remove non-generic
+       dummy frame handling.
+       (branch_dest, rs6000_pop_frame, rs6000_skip_trampoline_code,
+       rs6000_frame_saved_pc, frame_get_saved_regs,
+       frame_initial_stack_address, rs6000_frame_chain,
+       rs6000_convert_from_func_ptr_addr): Call read_memory_addr instead
+       of read_memory_integer.
+       (branch_dest, rs6000_pop_frame, rs6000_push_arguments,
+       rs6000_skip_trampoline_code, rs6000_frame_saved_pc,
+       frame_get_saved_regs, frame_initial_stack_address,
+       rs6000_frame_chain): Replace 4 with TDEP->wordsize.
+       (skip_prologue): Recognize some 64-bit stack adjustments.
+       (push_dummy_frame, pop_dummy_frame, set_processor,
+       show_processor): Delete.
+       (frame_get_saved_regs): Manipulate saved register addresses using
+       CORE_ADDR instead of int.
+       (rs6000_create_inferior): New function.
+       (register_names_*[]): Change to struct reg registers_*[].
+       (variants[]): Assimilate into multi-arch approach.
+       (register_names_*[], variants[]): Refer to pre-PowerPC
+       architectures as POWER instead of RS6000.
+       * rs6000-nat.c: Ubiquitous changes for 64-bit support.
+       (vmap_secs, xcoff_relocate_symtab): Cast addresses
+       to unsigned long to avoid sign-extension errors.
+       (set_host_arch): New function.
+       (xcoff_relocate_symtab): Try disabling usleep(36000) workaround.
+       (rs6000_core_fns): Use new bfd_target_xcoff_flavour.
+       (_initialize_core_rs6000): Initialize rs6000_set_host_arch_hook.
+       * symfile.c (find_sym_fns): Remove special xcoff kludge.
+       * xcoffread.c (secnum_to_bfd_section): Initialize args.objfile.
+       (process_linenos): Query line struct size from coff
+       backend instead of using compile-time constant.
+       (enter_line_range): Likewise.
+       (read_xcoff_symtab): Pass "XCOFF64" instead of "XCOFF" to
+       record_debugformat() if appropriate.
+       (process_xcoff_symbol): Access symbol addresses using
+       SYMBOL_VALUE_ADDRESS instead of SYMBOL_VALUE.
+       (read_symbol_lineno): Retrieve XCOFF64 symbol names from strtbl.
+       (scan_xcoff_symtab): Likewise.  Query syment struct size from
+       coff backend instead of using compile-time constant.
+       (xcoff_sym_fns): Set flavour to bfd_target_xcoff_flavour.
+       * Makefile.in (INTERNAL_LDFLAGS): Add $(MH_LDFLAGS) to list of flags
+       that this Makefile variable get set to.  (From Kevin Buettner.)
+       * config/powerpc/aix.mh (MH_LDFLAGS): Add linker flags so that
+       the TOC doesn't overflow.  (From Kevin Buettner.)
+       * config/powerpc/tm-ppc-aix.h: Move config decisions to
+       multi-arched rs6000-tdep.c.
