87ad46af87 [AArch64] Fix test failures on elf configuration
This patch fixed those failures on elf configuration by:

   * Improve the ILP32 target selector "aarch64_choose_ilp32_emul",
     makes it more robust. Target triples copied from configure.tgt

   * Updated emit-relocs-86/-overflow.d to use aarch64_choose_ilp32_emul
     which is following what have done with emit-relocs-28.

   * Those instruction encoding mismatch is because those encoding
     contains pc-relative address. As for elf, we may have different
     start address. relaxed encodind check, especially for
     aarch64-farcall-b/bl-plt, as the main purpose of those check are
     ELF text/data layout, we just want to make sure veneer to plt stub
     is generated.

244558af86 [regression] Do not read from catchpoint/watchpoint locations' addresses when checking for a permanent breakpoint
While running bare-metal tests with GDB i noticed some failures in
gdb.base/break.exp, related to the use of the catch commands.

It turns out GDB tries to access memory address 0x0 whenever one tries
to insert a catchpoint, which should obviously not happen.

This was introduced with the changes for permanent breakpoints. In special,
bp_loc_is_permanent tries to check if there is a breakpoint inserted at
the same address as the current breakpoint's location's address. In the
case of catchpoints, this is 0x0.

(top-gdb) catch fork
Sending packet: $m0,1#fa...Packet received: E01
Catchpoint 4 (fork)

(top-gdb) catch vfork
Sending packet: $m0,1#fa...Packet received: E01
Catchpoint 5 (vfork)

It is not obvious to detect because this fails silently for Linux. For our
bare-metal testing, though, this fails with a clear error message from the
target about not being able to read such address.

The attached patch addresses this by bailing out of bp_loc_is_permanent (...)
if the location address is not meaningful. I also took the opportunity to
update the comment for breakpoint_address_is_meaningful, which mentioned
breakpoint addresses as opposed to their locations' addresses.

gdb/ChangeLog:

2015-08-11  Luis Machado  <lgustavo@codesourcery.com>

	* breakpoint.c (bp_loc_is_permanent): Return 0 when breakpoint
	location address is not meaningful.
	(breakpoint_address_is_meaningful): Update comment.

87f0e72047 Explicit locations: add UI features for CLI
This patch exposes explicit locations to the CLI user.  This enables
users to "explicitly" specify attributes of the breakpoint location
to avoid any ambiguity that might otherwise exist with linespecs.

The general syntax of explicit locations is:
-source SOURCE_FILENAME -line {+-}LINE -function FUNCTION_NAME
-label LABEL_NAME

Option names may be abbreviated, e.g., "-s SOURCE_FILENAME -li 3" and users
may use the completer with either options or values.

gdb/ChangeLog:

	* completer.c: Include location.h.
	(enum match_type): New enum.
	(location_completer): Rename to ...
	(linespec_completer): ... this.
	(collect_explicit_location_matches, backup_text_ptr)
	(explicit_location_completer): New functions.
	(location_completer): "New" function; handle linespec
	and explicit location completions.
	(complete_line_internal): Remove all location completer-specific
	handling.
	* linespec.c (linespec_lexer_lex_keyword, is_ada_operator)
	(find_toplevel_char): Export.
	(linespec_parse_line_offset): Export.
	Issue error if STRING is not numerical.
	(gdb_get_linespec_parser_quote_characters): New function.

f00aae0f7b Explicit locations: use new location API
This patch converts the code base to use the new struct event_location
API being introduced. This patch preserves the current functionality and
adds no new features.

The "big picture" API usage introduced by this patch may be illustrated
with a simple exmaple. Where previously developers would write:

void
my_command (char *arg, int from_tty)
{
   create_breakpoint (..., arg, ...);
   ...
}

one now uses:

void
my_command (char *arg, int from_tty)
{
   struct event_locaiton *location;
   struct cleanup *back_to;

   location = string_to_event_locaiton (&arg, ...);
   back_to = make_cleanup_delete_event_location (location);
   create_breakpoint (..., location, ...);
   do_cleanups (back_to);
}

Linespec-decoding functions (now called location-decoding) such as
decode_line_full no longer skip argument pointers over processed input.
That functionality has been moved into string_to_event_location as
demonstrated above.

c7c1b3e998 Explicit locations: introduce new struct event_location-based API
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.
	* linespec.h (linespec_lex_to_end): Declare.
	* location.c: New file.
	* location.h: New file.

5f700d83f7 Explicit locations: rename "address string"/"addr_string" to "location"
This patch renames all occurrances of "addr_string" and "address
string" in the breakpoint/linespec APIs.  This will emphasize the
change from address strings used in setting breakpoints (et al) to the
new locations-based API introduced in subsequent patches.

gdb/ChangeLog:

	Renamed to create_sals_from_location.
