* Makefile.in (hpread.o, pa64solib.o, somsolib.o): Add $(hppa_tdep_h) * hppa-tdep.c (hppa_objfile_priv_data): New. (SR4EXPORT_LDIL_OFFSET, SR4EXPORT_LDO_OFFSET): Use HPPA_INSTRUCTION_SIZE. (read_unwind_info): Use objfile_data to reference unwind info. (find_unwind_entry): Likewise. (hpread_adjust_stack_address): Move to hpread.c. (_initialize_hppa_tdep): Register hppa objfile data. * hppa-tdep.h (HPPA_INSTRUCTION_SIZE): Define. (unwind_table_entry, unwind_stub_types): Move from tm-hppa.h. (obj_unwind_info, obj_private_struct): Move from tm-hppa.h, and rename with hppa_ prefix. * hpread.c (hppa-tdep.h): Include. (hpread_adjust_stack_address): Move from hppa-tdep.c. (hpread_read_function_type, hpread_read_doc_function_type) (hpread_process_one_debug_symbol): Call hpread_adjust_stack_address directly. Use objfile_data to access solib data. * pa64solib.c (hppa-tdep.h): Include. (pa64_solib_add_solib_objfile): Use objfile_data to access solib data. * somsolib.c (hppa-tdep.h): Include. (som_solib_add_solib_objfile): Use objfile_data to access solib data. * config/pa/tm-hppa.h (frame_info, frame_saved_regs, value, type) (inferior_status): Remove unused forward declarations. (INSTRUCTION_SIZE): Move to hppa-tdep.c. (unwind_table_entry, unwind_stub_types, obj_unwind_info) (obj_private_struct): Move to hppa-tdep.h. (HPREAD_ADJUST_STACK_ADDRESS): Remove.
