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.
This patch introduces the new breakpoint/"linespec" API based on
a new struct event_location. This API currently only supports
traditional linespecs, maintaining the status quo of the code base.
Future patches will add additional functionality for other location
types such as address locations.
gdb/ChangeLog:
* Makefile.in (SFILES): Add location.c.
(HFILES_NO_SRCDIR): Add location.h.
(COMMON_OBS): Add location.o.
* linespec.c (linespec_lex_to_end): New function.
