# Host: IBM PowerPC running AIX
XM_FILE= xm-aix.h
NAT_FILE= nm-aix.h
Add auto-solib-add support for AIX, remove obsolete and unused SOLIB_SYMBOLS_MANUAL code, cleanup of AIX shared library handling code. * rs6000-nat.c (vmap_symtab): Do not try to modify offsets if symbols are not yet loaded. (vmap_add_symbols): New function to add symbols for a vmap entry. (add_vmap): Turn errors into warnings, return NULL vmap upon failure. Add symbols via vmap_add_symbols only if requested. (xcoff_relocate_core): Allow debugging of core files without an executable file. Handle NULL returns from add_vmap gracefully. * xcoffsolib.c (solib_add): Remove, no longer needed. (solib_info): Do not check for new shared libraries if there is no inferior process. (sharedlibrary_command): Made static. Do not check for new shared libraries if there is no inferior process. Add symbols for requested shared libraries via vmap_add_symbols. (_initialize_solib): Add `set auto-solib-add' command. * xcoffsolib.h (vmap_add_symbols): Add prototype declaration. * config/rs6000/tm-rs6000.h (PC_LOAD_SEGMENT): Move from here ... * config/rs6000/nm-rs6000.h: ... to here, this is an AIX native feature. * config/powerpc/tm-macos.h, config/powerpc/tm-ppc-eabi.h, config/powerpc/tm-ppc-nw.h, config/rs6000/tm-rs6000ly.h: Remove #undef PC_LOAD_SEGMENT. * config/powerpc/aix.mt, config/rs6000/aix4.mt, config/rs6000/rs6000.mt (TDEPFILES): Move xcoffsolib.o from here ... * config/powerpc/aix.mh, config/rs6000/aix4.mh, config/rs6000/rs6000.mh (NATDEPFILES): ... to here, xcoffsolib.o contains AIX native code only. * rs6000-tdep.c: Remove #include xcoffsolib.h, no longer needed. * xcoffsolib.h (xcoff_relocate_symtab_hook): Remove declaration. * rs6000-nat.c (_initialize_core_rs6000): Remove setting of xcoff_relocate_symtab_hook, no longer needed. * xcoffsolib.c (solib_info, sharedlibrary_command): Remove xcoff_relocate_symtab_hook indirection, call xcoff_relocate_symtab directly, as xcoffsolib.c is now compiled in native AIX configurations only. * Makefile.in: Update dependencies for rs6000-tdep.o, rs6000-nat.o and xcoffsolib.o.

* 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.
