Keep objfile original filename
gdb/ 2013-09-24 Jan Kratochvil <jan.kratochvil@redhat.com> Pass down original filename for objfile. * coffread.c (coff_symfile_read): Update symbol_file_add_separate call. * elfread.c (elf_symfile_read): Likewise. * jit.c (jit_object_close_impl): Update allocate_objfile call, no longer set ORIGINAL_NAME. (jit_bfd_try_read_symtab): Update symbol_file_add_from_bfd call. * jv-lang.c (get_dynamics_objfile): Update allocate_objfile call. * machoread.c (macho_add_oso_symfile): Add parameter name. Update symbol_file_add_from_bfd call. (macho_symfile_read_all_oso): Update two macho_add_oso_symfile calls. (macho_check_dsym): Add parameter filenamep. Change function comment. Set *filenamep. (macho_symfile_read): New variable dsym_filename. Update macho_check_dsym call. Use it for symbol_file_add_separate. * objfiles.c (allocate_objfile): Add parameter name. New comment for it. Use it for objfile->original_name. (objfile_name): Return OBFD's filename, if available. * objfiles.h (allocate_objfile): Add new parameter name. * solib.c (solib_read_symbols): Update symbol_file_add_from_bfd call. * symfile-mem.c (symbol_file_add_from_memory): Update symbol_file_add_from_bfd call. * symfile.c (read_symbols): Update symbol_file_add_separate call, new comment for it. (symbol_file_add_with_addrs): New parameter name, add function comment for it. Remove variable name. Update allocate_objfile call. (symbol_file_add_separate): New parameter name, add function comment for it. Update symbol_file_add_with_addrs call. (symbol_file_add_from_bfd): New parameter name. Update symbol_file_add_with_addrs call. (symbol_file_add): Update symbol_file_add_from_bfd call. (reread_symbols): New variable original_name. Save objfile->original_name by it. * symfile.h (symbol_file_add_from_bfd, symbol_file_add_separate): Add second parameter.
