* 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.
* config/rs6000/tm-rs6000.h: Likewise.
(GDB_MULTI_ARCH): Define.
(skip_trampoline_code): Rename to rs6000_skip_trampoline_code.
(is_magic_function_pointer): Replace with
rs6000_convert_from_func_ptr_addr.
(TARGET_CREATE_INFERIOR_HOOK): Define.
(find_toc_address_hook): Rename to rs6000_find_toc_address_hook.
