(gdbarch_info_fill): Call it. * target-descriptions.c (struct property): Make members non-const. (struct target_desc): Add arch member. (target_description_filename): New variable. (target_find_description): Try via XML first. (tdesc_architecture): New. (free_target_description, make_cleanup_free_target_description): New. (set_tdesc_property): Call xstrdup. (set_tdesc_architecture, tdesc_set_cmdlist, tdesc_show_cmdlist) (tdesc_unset_cmdlist, unset_tdesc_cmd, unset_tdesc_filename_cmd) (set_tdesc_cmd, show_tdesc_cmd, set_tdesc_filename_cmd) (show_tdesc_filename_cmd, _initialize_target_descriptions): New. * target-descriptions.h (tdesc_architecture) (make_cleanup_free_target_description, set_tdesc_architecture): New prototypes. * Makefile.in (SFILES): Add xml-tdesc.c. (COMMON_OBS): Add xml-tdesc.o. (target-descriptions.o): Update. (xml-tdesc.o): New rule. * xml-tdesc.c, xml-tdesc.h: New files. * remote.c (PACKET_qXfer_features): New enum. (remote_protocol_features): Add qXfer:features:read. (remote_xfer_partial): Handle TARGET_OBJECT_AVAILABLE_FEATURES. (_initialize_remote): Register qXfer:features:read. * target.h (enum target_object): Add TARGET_OBJECT_AVAILABLE_FEATURES. * features/gdb-target.dtd: New file. * linux-i386-low.c (the_low_target): Set arch_string. * linux-x86-64-low.c (the_low_target): Likewise. * linux-low.c (linux_arch_string): New. (linux_target_ops): Add it. * linux-low.h (struct linux_target_ops): Add arch_string. * server.c (write_qxfer_response): Use const void * for DATA. (get_features_xml): New. (handle_query): Handle qXfer:features:read. Report it for qSupported. * target.h (struct target_ops): Add arch_string method. * gdb.texinfo (Target Descriptions): New section. (General Query Packets): Add QPassSignals anchor. Mention qXfer:features:read under qSupported. Expand mentions of qXfer:memory-map:read and QPassSignals.
