Explicit locations: introduce address locations
This patch adds support for address locations, of the form "*ADDR". [Support for address linespecs has been removed/replaced by this "new" location type.] This patch also converts any existing address locations from its previous linespec type. gdb/ChangeLog: * breakpoint.c (create_thread_event_breakpoint, init_breakpoint_sal): Convert linespec to address location. * linespec.c (canonicalize_linespec): Do not handle address locations here. (convert_address_location_to_sals): New function; contents moved from ... (convert_linespc_to_sals): ... here. (parse_linespec): Remove address locations from linespec grammar. Remove handling of address locations. (linespec_lex_to_end): Remove handling of address linespecs. (event_location_to_sals): Handle ADDRESS_LOCATION. (linespec_expression_to_pc): Export. * linespec.h (linespec_expression_to_pc): Add declaration. * location.c (struct event_location.u) <address>: New member. (new_address_location, get_address_location): New functions. (copy_event_location, delete_event_location, event_location_to_string) (string_to_event_location, event_location_empty_p): Handle address locations. * location.h (enum event_location_type): Add ADDRESS_LOCATION. (new_address_location, get_address_location): Declare. * python/py-finishbreakpoint.c (bpfinishpy_init): Convert linespec to address location. * spu-tdep.c (spu_catch_start): Likewise.
