    Ah, it seems I mailed a bad patch, my apologies!  I was working on
    two fixes that touched the same line, and it looks like I rebased
    them in the wrong order.
    
    This updated patch has been created against the latest gdb/master
    (80fb91378c91a8239817a5ab2b1c3e346109db25).  Could you please try
    your tests again?
    
    Thanks,
    Gary

    On attach, GDB will only attempt to determine the main executable's
    filename if one is not already set.  This causes problems if you
    attach to one process and then attach to another: GDB will not attempt
    to discover the main executable on the second attach.  If the two
    processes have different main executable files then the symbols will
    now be wrong.  This is PR gdb/17626.
    
    In GDB some filenames are supplied by the user (e.g. using the "file"
    or "symbol-file" commands) and some are determined by GDB (e.g. while
    processing an "attach" command).  This commit updates GDB to track
    which filenames were supplied by the user.  When GDB might attempt to
    determine an executable filename and one is already set, filenames
    determined by GDB may be overridden but user-supplied filenames will
    not.

    It didn't seem fair to impose a subjective preference, so I tried
    this in order to understand it myself, and I now agree that is really
    doesn't make much difference, as then we'd have to mark
    auto-discovered in a few more places that I wasn't originally
    seeing.  There's at least the execd handling in infrun.c, and
    also spu_symbol_file_add_from_memory.
    
    As I was playing with this already, I poked at the other review
    points I made, and came up with the variant of the patch below.

    I tried this too (see patch below).  As this requires touching the user-supplied
    paths anyway, it didn't really matter to tag files user-supplied or
    auto-discovered, so I reverted back to user-supplied.  For symbols,
    we already have the add_flags, so I added SYMFILE_USER_SUPPLIED instead
    of a new boolean.

    Ah, it seems I mailed a bad patch, my apologies!  I was working on
    two fixes that touched the same line, and it looks like I rebased
    them in the wrong order.
    
    This updated patch has been created against the latest gdb/master
    (80fb91378c91a8239817a5ab2b1c3e346109db25).  Could you please try
    your tests again?
    
    Thanks,
    Gary

    On attach, GDB will only attempt to determine the main executable's
    filename if one is not already set.  This causes problems if you
    attach to one process and then attach to another: GDB will not attempt
    to discover the main executable on the second attach.  If the two
    processes have different main executable files then the symbols will
    now be wrong.  This is PR gdb/17626.
    
    In GDB some filenames are supplied by the user (e.g. using the "file"
    or "symbol-file" commands) and some are determined by GDB (e.g. while
    processing an "attach" command).  This commit updates GDB to track
    which filenames were supplied by the user.  When GDB might attempt to
    determine an executable filename and one is already set, filenames
    determined by GDB may be overridden but user-supplied filenames will
    not.
    
    gdb/ChangeLog:
    
    	PR gdb/17626
    	* progspace.h (struct program_space)
    	<pspace_exec_file_is_user_supplied>: New field.
    	<symfile_object_file_is_user_supplied>: Likewise.
    	(symfile_objfile_is_user_supplied): New macro.
    	* exec.h (exec_file_is_user_supplied): Likewise.
    	* exec.c (exec_close): Clear exec_file_is_user_supplied.
    	(exec_file_locate_attach): Remove get_exec_file check.
    	Do not replace user-supplied executable or symbol files.
    	Warn if user-supplied executable or symbol files do not
    	match discovered file.
    	(exec_file_command): Set exec_file_is_user_supplied.
    	* symfile.c (symbol_file_clear): Clear
    	symfile_objfile_is_user_supplied.
    	(symbol_file_command): Set symfile_objfile_is_user_supplied.
    	* inferior.c (add_inferior_command): Set
    	exec_file_is_user_supplied and symfile_objfile_is_user_supplied.
    	* main.c (captured_main): Likewise.
    	* infcmd.c (attach_command_post_wait): Always call
    	exec_file_locate_attach.  Only call reopen_exec_file and
    	reread_symbols if exec_file_is_user_supplied.
    	* remote.c (remote_add_inferior): Remove get_exec_file check
    	around exec_file_locate_attach.

    New /s modifier for the disassemble command.
    
    The "source centric" /m option to the disassemble command is often
    unhelpful, e.g., in the presence of optimized code.
    This patch adds a /s modifier that is better.
    For one, /m only prints instructions from the originating source file,
    leaving out instructions from e.g., inlined functions from other files.

    A recent patch introduced a variable named `typename' into d-exp.y,

    Rename location accessor macro parameters to silence ARI
    
    The locations patch I recently committed contains macro definitions
    such as:
    
    This causes an ARI error to be emitted by the server ("Do not use PTR, ISO C
    90 implies `void *'").  While this ARI error is bogus in this context,
    it is just easiest to squash the error completely by renaming the macro
    parameters.

    mi_make_breakpoint: add "evaluated-by" option
    
    For some time now, GDB has permitted target-side evaluation of
    breakpoint conditions.  On targets that support this feature, GDB
    may output an "evaluated-by" field into the breakpoint reply.
    
    This patch adds handling for this option, and outputs a default
    pattern to optionally recognize (and ignore) this pattern in the
    reply.

    [D] Move classification of symbols from the grammar to the lexer.
    
    This makes it so that alternating '.' and identifier tokens are resolved to
    symbols as early as possible, which should all the addition of D properties -
    such as EXP.sizeof and EXP.typeof - without the shift/reduce conflicts that
    would occur in the current parsing strategy.
    
    gdb/ChangeLog
    
    	* d-exp.y (%union): Add voidval.
    	(%token): Add UNKNOWN_NAME as a token to represent an unclassified
    	name in the lexing stage.
    	(PostfixExpression): Move symbol completion handling in grammar here
    	from PrimaryExpression.
    	(PrimaryExpression): Move routines to handle resolving identifier
    	tokens in the grammar here from push_expression_name.
    	(IdentifierExp): Remove the handling of alternating '.' and identifier
    	tokens.
    	(TypeExp): Allow TypeExp to be wrapped in parenthesis in the grammar.
    	(BasicType): Remove C-style typename rules.
    	(d_type_from_name, d_module_from_name, push_variable)
    	(push_fieldnames, push_type_name, push_module_name)
    	(push_expression_name): Remove.
    	(lex_one_token): Rename from yylex.  Replace pstate with par_state.
    	(token_and_value): New type.
    	(token_fifo, popping, name_obstack): New globals.
    	(classify_name): New function.
    	(classify_inner_name): Likewise.
    	(yylex): Likewise.
    	(d_parse): Initialize token_fifo, popping and name_obstack.

    [D] Support looking up symbols in the current and imported modules.
    
    In D, there is the notion of modules, and importing from one to the other,
    whether it is a basic, selective or renamed import declaration.
    
    	module A;
    	import X;
    	void foo() {
    	  import Y : bar;
    	}
    
    If the compiler emits DW_TAG_imported_declaration at the appropriate locations,
    then we can make use of what gdb stores in using_direct when performing
    nonlocal symbol lookups.
    
    gdb/ChangeLog
    
    	* Makefile.in (SFILES): Add d-namespace.c.
    	(COMMON_OBS): Add d-namespace.o.
    	* d-lang.c (d_language_defn): Use d_lookup_symbol_nonlocal as the
    	la_lookup_symbol_nonlocal callback function pointer.
    	* d-lang.h (d_lookup_symbol_nonlocal): New declaration.
    	(d_lookup_nested_symbol): New declaration.
    	* d-namespace.c: New file.

    Mass rename `explicit' -> `explicit_loc'.
    
    BuildBot reminded me that "explicit" is a reserved keyword in C++.
    This patch simply renames all the (illegal) uses of "explicit". This should
    fix the build errors with --enable-build-with-cxx bots.
    
    gdb/ChangeLog
    
    	* break-catch-throw.c (re_set_exception_catchpoint) Rename
    	reserved C++ keyword "explicit" to "explicit_loc".
    	* breakpoint.c (create_overlay_event_breakpoint)
    	(create_longjmp_master_breakpoint)
    	(create_std_terminate_master_breakpoint)
    	(create_exception_master_breakpoint, update_static_tracepoint):
    	Rename reserved C++ keyword "explicit" to "explicit_loc".
    	* completer.c (collect_explicit_location_matches)
    	(explicit_location_completer): Rename reserved C++ keyword
    	"explicit" to "explicit_loc".
    	* linespec.c (struct linespec) <explicit>: Rename to "explicit_loc".
    	(canonicalize_linespec, create_sals_line_offset)
    	(convert_linespec_to_sals, convert_explicit_location_to_sals)
    	(event_location_to_sals, decode_objc): Rename reserved C++ keyword
    	"explicit" to "explicit_loc".
    	* location.c (struct event_location) <explicit>: Rename to
    	"explicit_loc".
    	(initialize_explicit_location, new_explicit_location)
    	(explicit_location_to_string_internal, explicit_location_to_linespec):
    	Rename reserved C++ keyword "explicit" to "explicit_loc".

    Ah, it seems I mailed a bad patch, my apologies!  I was working on
    two fixes that touched the same line, and it looks like I rebased
    them in the wrong order.
    
    This updated patch has been created against the latest gdb/master
    (80fb91378c91a8239817a5ab2b1c3e346109db25).  Could you please try
    your tests again?
    
    Thanks,
    Gary

    On attach, GDB will only attempt to determine the main executable's
    filename if one is not already set.  This causes problems if you
    attach to one process and then attach to another: GDB will not attempt
    to discover the main executable on the second attach.  If the two
    processes have different main executable files then the symbols will
    now be wrong.  This is PR gdb/17626.
    
    In GDB some filenames are supplied by the user (e.g. using the "file"
    or "symbol-file" commands) and some are determined by GDB (e.g. while
    processing an "attach" command).  This commit updates GDB to track
    which filenames were supplied by the user.  When GDB might attempt to
    determine an executable filename and one is already set, filenames
    determined by GDB may be overridden but user-supplied filenames will
    not.
    
    gdb/ChangeLog:
    
    	PR gdb/17626
    	* progspace.h (struct program_space)
    	<pspace_exec_file_is_user_supplied>: New field.
    	<symfile_object_file_is_user_supplied>: Likewise.
    	(symfile_objfile_is_user_supplied): New macro.
    	* exec.h (exec_file_is_user_supplied): Likewise.
    	* exec.c (exec_close): Clear exec_file_is_user_supplied.
    	(exec_file_locate_attach): Remove get_exec_file check.
    	Do not replace user-supplied executable or symbol files.
    	Warn if user-supplied executable or symbol files do not
    	match discovered file.
    	(exec_file_command): Set exec_file_is_user_supplied.
    	* symfile.c (symbol_file_clear): Clear
    	symfile_objfile_is_user_supplied.
    	(symbol_file_command): Set symfile_objfile_is_user_supplied.
    	* inferior.c (add_inferior_command): Set
    	exec_file_is_user_supplied and symfile_objfile_is_user_supplied.
    	* main.c (captured_main): Likewise.
    	* infcmd.c (attach_command_post_wait): Always call
    	exec_file_locate_attach.  Only call reopen_exec_file and
    	reread_symbols if exec_file_is_user_supplied.
    	* remote.c (remote_add_inferior): Remove get_exec_file check
    	around exec_file_locate_attach.

    Issue an error for read-only segment with dynamic IFUNC relocations
    
    To load an ELF binary with DT_TEXTREL tag, the dynamic linker calls
    __mprotect on the read-only segment with PROT_READ|PROT_WRITE before
    applying dynamic relocation.  It leads to segfault when performing
    IFUNC relocations since the read-only segment has no execute permission.
    This patch changes x86 linker to issue an error for read-only segment
    with dynamic IFUNC relocations.  Other backends with IFUNC support
    may need a similar change.

    [Ada] Add support for subprogram renamings
    
    Consider the following declaration:
    
        function Foo (I : Integer) return Integer renames Pack.Bar;
    
    As Foo is not materialized as a routine whose name is derived from Foo,
    GDB currently cannot use it:
    
        (gdb) print foo(0)
        No definition of "foo" in current context.
    
    However, compilers can emit DW_TAG_imported_declaration in order to
    materialize the fact that Foo is actually another name for Pack.Bar.
    This commit enhances the DWARF reader to record global renamings (it
    used to put global ones in a static block) and enhances the Ada engine
    to leverage this information during symbol lookup.

    gdb.base/dso2dso.exp sometimes broken
    
    Keith reported that gdb.base/dso2dso.exp is broken, with the following
    error:

    This happens because gdb_get_line_number will prepend $srcdir/$subdir
    if the given filename does not start with "/", and this happens when
    GDB was configured using a relative path to the configure script.
    When using an absolute path like I do, we avoid the pre-pending that
    Keith is seeing.

    Set EI_OSABI to ELFOSABI_GNU for local IFUNC symbols
    
    Since the backend elf_add_symbol_hook isn't called on local symbols,
    the EI_OSABI field isn't to ELFOSABI_GNU where are local IFUNC symbols.
    This patch changes the x86 backends to set has_gnu_symbols if there are
    relocations against IFUNC symbols.  Other backends with IFUNC support
    may need a similar change.

    [amd64] Invalid return address after displaced stepping
    
    Making all-stop run on top of non-stop caused a small regression
    in behavior. This was observed on x86_64-linux. The attached testcase
    is in C whereas the investigation was done with an Ada program,
    but it's the same scenario, and using a C testcase allows wider testing.
    Basically: I am debugging a single-threaded program, and currently
    stopped inside a function provided by a shared-library, at a line
    calling a subprogram provided by a second shared library, and trying
    to "next" over that function call.
    
    Before we changed the default all-stop behavior, we had:
    
        7             Impl_Initialize;  -- Stop here and try "next" over this line
        (gdb) n
        8             return 5;  <<-- OK
    
    But now, "next" just stops much earlier:
    
        (gdb) n
        0x00007ffff7bd8560 in impl.initialize@plt () from /[...]/lib/libpck.so
    
    What happens is that next stops at a call instruction, which calls
    the function's PLT, and GDB fails to notice that the inferior stepped
    into a subroutine, and so decides that we're done. We can see another
    symptom of the same issue by looking at the backtrace at the point
    GDB stopped:
    
        (gdb) bt
        #0  0x00007ffff7bd8560 in impl.initialize@plt ()
           from /[...]/lib/libpck.so
        #1  0x00000000f7bd86f9 in ?? ()
        #2  0x00007fffffffdf50 in ?? ()
        #3  0x0000000000401893 in a () at /[...]/a.adb:7
        Backtrace stopped: frame did not save the PC
    
    With a functioning GDB, the backtrace looks like the following instead:
    
        #0  0x00007ffff7bd8560 in impl.initialize@plt ()
           from /[...]/lib/libpck.so
        #1  0x00007ffff7bd86f9 in sub () at /[...]/pck.adb:7
        #2  0x0000000000401893 in a () at /[...]/a.adb:7
    
    Note how, for frame #1, the address looks quite similar, except
    for the high-order bits not being set:
    
        #1  0x00007ffff7bd86f9 in sub () at /[...]/pck.adb:7   <<<--  OK
        #1  0x00000000f7bd86f9 in ?? ()                        <<<--  WRONG
                  ^^^^
                  ||||
                  Wrong
    
    Investigating this further led me to displaced stepping.
    As we are "next"-ing from a location where a breakpoint is inserted,
    we need to step out of it, and since we're on non-stop mode, we need
    to do it using displaced stepping. And looking at
    amd64-tdep.c:amd64_displaced_step_fixup, I found the code that handles
    the return address:
    
        regcache_cooked_read_unsigned (regs, AMD64_RSP_REGNUM, &rsp);
        retaddr = read_memory_unsigned_integer (rsp, retaddr_len, byte_order);
        retaddr = (retaddr - insn_offset) & 0xffffffffUL;
    
    The mask used to compute retaddr looks wrong to me, keeping only
    4 bytes instead of 8, and explains why the high order bits of
    the backtrace are unset. What happens is that, after the displaced
    stepping has completed, GDB restores that return address at the location
    where the program expects it.  But because the top half bits of
    the address have been masked out, the return address is now invalid.
    The incorrect behavior of the "next" command and the backtrace at
    that location are the first symptoms of that.  Another symptom is
    that this actually alters the behavior of the program, where a "cont"
    from there soon leads to a SEGV when the inferior tries to jump back
    to that incorrect return address:
    
        (gdb) c
        Continuing.
    
        Program received signal SIGSEGV, Segmentation fault.
        0x00000000f7bd86f9 in ?? ()
        ^^^^^^^^^^^^^^^^^^
    
    This patch fixes the issue by using a mask that seems more appropriate
    for this architecture.

    pool candidate frags are planted every N frags and during relaxation
    they are turned into actual literal pools where literals are moved to
    become reachable for their first reference by L32R instruction.

    Guarantee save-and-restore of GDBFLAGS on gdb.base/checkpoint-ns.exp
    
    Keith found out that several tests were failing when testing the
    native-gdbserver board on Fedora (x86_64).  Strangely, these failures
    had not been reported by our BuildBot.  Later, he found that the reason
    for this was because the failures only happened when running the
    testsuite without FORCE_PARALLEL (i.e., on serial mode; maybe it would
    be worth having a builder testing things on serial...).  Then, he
    decided to start bisecting the changes to see which one introduced the
    failure (it was not trivial to know this only by looking at gdb.log).
    
    After a lot of time, he found that Pedro's commit
    e1316e60d4d1fe406efc6e7536b2bdb43733e9d2 was the culprit.  There was
    nothing wrong in the code, but the new gdb.base/checkpoint-ns.exp
    testcase did something that left the GDBFLAGS variable in an
    inconsistent state.  This test works by modifying this variable to set
    non-stop on, sourcing gdb.base/checkpoint.exp (which does the hard
    work), and then restoring the old value on GDBFLAGS.  However, this was
    not working because gdb.base/checkpoint.exp bails out if it is being
    tested on gdbserver, and when it calls "continue" the control goes back
    to the function calling the tests, and not to
    gdb.base/checkpoint-ns.exp.
    
    The fix is simple: just wrap the "source" call, and make
    gdb.base/checkpoint-ns.exp aware of the "continue"/"return" calls made
    by gdb.base/checkpoint.exp.

    Ah, it seems I mailed a bad patch, my apologies!  I was working on
    two fixes that touched the same line, and it looks like I rebased
    them in the wrong order.
    
    This updated patch has been created against the latest gdb/master
    (80fb91378c91a8239817a5ab2b1c3e346109db25).  Could you please try
    your tests again?
    
    Thanks,
    Gary

    On attach, GDB will only attempt to determine the main executable's
    filename if one is not already set.  This causes problems if you
    attach to one process and then attach to another: GDB will not attempt
    to discover the main executable on the second attach.  If the two
    processes have different main executable files then the symbols will
    now be wrong.  This is PR gdb/17626.
    
    In GDB some filenames are supplied by the user (e.g. using the "file"
    or "symbol-file" commands) and some are determined by GDB (e.g. while
    processing an "attach" command).  This commit updates GDB to track
    which filenames were supplied by the user.  When GDB might attempt to
    determine an executable filename and one is already set, filenames
    determined by GDB may be overridden but user-supplied filenames will
    not.
    
    gdb/ChangeLog:
    
    	PR gdb/17626
    	* progspace.h (struct program_space)
    	<pspace_exec_file_is_user_supplied>: New field.
    	<symfile_object_file_is_user_supplied>: Likewise.
    	(symfile_objfile_is_user_supplied): New macro.
    	* exec.h (exec_file_is_user_supplied): Likewise.
    	* exec.c (exec_close): Clear exec_file_is_user_supplied.
    	(exec_file_locate_attach): Remove get_exec_file check.
    	Do not replace user-supplied executable or symbol files.
    	Warn if user-supplied executable or symbol files do not
    	match discovered file.
    	(exec_file_command): Set exec_file_is_user_supplied.
    	* symfile.c (symbol_file_clear): Clear
    	symfile_objfile_is_user_supplied.
    	(symbol_file_command): Set symfile_objfile_is_user_supplied.
    	* inferior.c (add_inferior_command): Set
    	exec_file_is_user_supplied and symfile_objfile_is_user_supplied.
    	* main.c (captured_main): Likewise.
    	* infcmd.c (attach_command_post_wait): Always call
    	exec_file_locate_attach.  Only call reopen_exec_file and
    	reread_symbols if exec_file_is_user_supplied.
    	* remote.c (remote_add_inferior): Remove get_exec_file check
    	around exec_file_locate_attach.

    Ah, it seems I mailed a bad patch, my apologies!  I was working on
    two fixes that touched the same line, and it looks like I rebased
    them in the wrong order.
    
    This updated patch has been created against the latest gdb/master
    (80fb91378c91a8239817a5ab2b1c3e346109db25).  Could you please try
    your tests again?
    
    Thanks,
    Gary

    On attach, GDB will only attempt to determine the main executable's
    filename if one is not already set.  This causes problems if you
    attach to one process and then attach to another: GDB will not attempt
    to discover the main executable on the second attach.  If the two
    processes have different main executable files then the symbols will
    now be wrong.  This is PR gdb/17626.
    
    In GDB some filenames are supplied by the user (e.g. using the "file"
    or "symbol-file" commands) and some are determined by GDB (e.g. while
    processing an "attach" command).  This commit updates GDB to track
    which filenames were supplied by the user.  When GDB might attempt to
    determine an executable filename and one is already set, filenames
    determined by GDB may be overridden but user-supplied filenames will
    not.
    
    gdb/ChangeLog:
    
    	PR gdb/17626
    	* progspace.h (struct program_space)
    	<pspace_exec_file_is_user_supplied>: New field.
    	<symfile_object_file_is_user_supplied>: Likewise.
    	(symfile_objfile_is_user_supplied): New macro.
    	* exec.h (exec_file_is_user_supplied): Likewise.
    	* exec.c (exec_close): Clear exec_file_is_user_supplied.
    	(exec_file_locate_attach): Remove get_exec_file check.

    Ah, it seems I mailed a bad patch, my apologies!  I was working on
    two fixes that touched the same line, and it looks like I rebased
    them in the wrong order.
    
    This updated patch has been created against the latest gdb/master
    (80fb91378c91a8239817a5ab2b1c3e346109db25).  Could you please try
    your tests again?
    
    Thanks,
    Gary

    On attach, GDB will only attempt to determine the main executable's
    filename if one is not already set.  This causes problems if you
    attach to one process and then attach to another: GDB will not attempt
    to discover the main executable on the second attach.  If the two
    processes have different main executable files then the symbols will
    now be wrong.  This is PR gdb/17626.
    
    In GDB some filenames are supplied by the user (e.g. using the "file"
    or "symbol-file" commands) and some are determined by GDB (e.g. while
    processing an "attach" command).  This commit updates GDB to track
    which filenames were supplied by the user.  When GDB might attempt to
    determine an executable filename and one is already set, filenames
    determined by GDB may be overridden but user-supplied filenames will
    not.

    Ah, it seems I mailed a bad patch, my apologies!  I was working on
    two fixes that touched the same line, and it looks like I rebased
    them in the wrong order.
    
    This updated patch has been created against the latest gdb/master
    (80fb91378c91a8239817a5ab2b1c3e346109db25).  Could you please try
    your tests again?
    
    Thanks,
    Gary

    On attach, GDB will only attempt to determine the main executable's
    filename if one is not already set.  This causes problems if you
    attach to one process and then attach to another: GDB will not attempt
    to discover the main executable on the second attach.  If the two
    processes have different main executable files then the symbols will
    now be wrong.  This is PR gdb/17626.
    
    In GDB some filenames are supplied by the user (e.g. using the "file"
    or "symbol-file" commands) and some are determined by GDB (e.g. while
    processing an "attach" command).  This commit updates GDB to track
    which filenames were supplied by the user.  When GDB might attempt to
    determine an executable filename and one is already set, filenames
    determined by GDB may be overridden but user-supplied filenames will
    not.
    
    gdb/ChangeLog:
    
    	PR gdb/17626
    	* progspace.h (struct program_space)
    	<pspace_exec_file_is_user_supplied>: New field.
    	<symfile_object_file_is_user_supplied>: Likewise.

    	* exec.h (exec_file_is_user_supplied): Likewise.
    	* exec.c (exec_close): Clear exec_file_is_user_supplied.
    	(exec_file_locate_attach): Remove get_exec_file check.
    	Do not replace user-supplied executable or symbol files.
    	Warn if user-supplied executable or symbol files do not
    	match discovered file.
    	(exec_file_command): Set exec_file_is_user_supplied.
    	* symfile.c (symbol_file_clear): Clear
    	symfile_objfile_is_user_supplied.
    	(symbol_file_command): Set symfile_objfile_is_user_supplied.
    	* inferior.c (add_inferior_command): Set
    	exec_file_is_user_supplied and symfile_objfile_is_user_supplied.
    	* main.c (captured_main): Likewise.
    	* infcmd.c (attach_command_post_wait): Always call
    	exec_file_locate_attach.  Only call reopen_exec_file and
    	reread_symbols if exec_file_is_user_supplied.

    [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.

      four triple shapes: aarch64-*-linux*, aarch64-*-elf,
      aarch64_be-*-linux*, aarch64_be-*-elf.
      * ld-aarch64/emit-relocs-86.d: Use aarch64_choose_ilp32_emul.

    [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.

    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.

    	and explicit location completions.
    	(complete_line_internal): Remove all location completer-specific
    	handling.
    	* linespec.c (linespec_lexer_lex_keyword, is_ada_operator)

    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.
    
    gdb/ChangeLog

    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.

    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.

    	* breakpoint.h (struct breakpoint_ops) <create_sals_from_address>:
