py-linetable.c: Fix doc of LineTable.source_lines' return type
The ltpy_get_all_source_lines function, use to implement
the gdb.LineTable.source_lines method, returns a list:
source_list = PyDict_Keys (source_dict);
return source_list;
This patch fixes the function's documentation as well as its docstring

gdb/gdbtypes: fix handling of typedef layers between array types
When a dynamic array type contains a typedef-wrapped array, an assertion
failure occurs during type resolution. This is what happens in the
following Ada case:
type Rec_Type is record
I : Integer;
B : Boolean;
end record;
type Vec_Type is array (1 .. 4) of Rec_Type;
type Array_Type is array (Positive range <>) of Vec_Type;
If users try to print or even pass to an inferior call a variable A of
type Array_Type, GDB will raise an error:
(gdb) print a
../../src/gdb/gdbtypes.c:1807: internal-error:
resolve_dynamic_array: Assertion `TYPE_CODE (type) ==
TYPE_CODE_ARRAY' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
What happens is that during dynamic array type resolution, we first peel
TYPE_CODE_TYPEDEF layers wrapping the array element type and check if
its type is itself TYPE_CODE_ARRAY. If it is, we pass the
typedef-wrapped type to a recursive call to resolve_dynamic_array
whereas this function expects only TYPE_CODE_ARRAY types.
This patch makes it pass the peeled type to the recursive call so that
type resolution can continue smoothly.
gdb/ChangeLog:
* gdbtypes.c (resolve_dynamic_array): Pass the peeled element
type to the recursive call instead of the original (maybe
TYPE_CODE_TYPEDEF) type.

Since multi_line was moved to gdb.exp in a slightly stricter form,
The gdb.ada/info_exc.exp:info exceptions test has been failing.
This is because it now expects a new-line sequence at the end of
each argument given to multi_line, including ".*". But the intent
when writing the test was to signify "could-be-nothing-at-all".
As a result, the test fails on x86_64-linux with a runtime built as

Move common aarch64 HW breakpoint/watchpoint code to nat/
When I look at test fails related to watchpoint on aarch64-linux,
I find there are some code duplicates between GDB and GDBserver.
This patch is to move some of them to a nat/aarch64-linux-hw-point.{h,c}.
The only change I do is about the dr_changed_t typedef, which was
ULONGEST in GDB and 'unsigned long long' in GDBserver. Each bit
of dr_changed_t represents a status of each HW breakpoint or
watchpoint register, and the max number of HW breakpoint or watchpoint
registers is 16, so the width of 'unsigned long long' is sufficient.

Pass aarch64_debug_reg_state to functions
Some functions on handling HW watchpoint in GDB and GDBserver looks the
same except the code getting debug register state from current inferior.
In GDB, we get debug register state like this:
state = aarch64_get_debug_reg_state (ptid_get_pid (inferior_ptid));
while in GDBserver, we get debug register state like this:
state = aarch64_get_debug_reg_state ();
This patch is to move two lines above out of some functions, and pass
aarch64_debug_reg_state to these functions, in this way, these functions
are the same, and can be moved to a common place.

Some functions in aarch64-linux-nat.c and linux-aarch64-low.c looks

Call ptid_get_pid instead of get_thread_id in aarch64_linux_get_debug_reg_capacity
aarch64_linux_get_debug_reg_capacity is called by
aarch64_linux_child_post_startup_inferior, and argument ptid is created in
inf-ptrace.c:inf_ptrace_create_inferior,
/* On some targets, there must be some explicit actions taken after
the inferior has been started up. */
target_post_startup_inferior (pid_to_ptid (pid));
so in aarch64_linux_get_debug_reg_capacity, we can get pid by ptid_get_pid,
and don't need to use get_thread_id.

Fix gdb.arch/i386-biarch-core.exp FAIL on i386.
This new test fails on i686 buildbot slaves,
(gdb) core-file /home/gdb-buildbot-2/fedora-x86-64-2/fedora-i686/build/gdb/testsuite/gdb.arch/i386-biarch-core.core
"/home/gdb-buildbot-2/fedora-x86-64-2/fedora-i686/build/gdb/testsuite/gdb.arch/i386-biarch-core.core"
is not a core dump: File format not recognized
(gdb) FAIL: gdb.arch/i386-biarch-core.exp: core-file
There are two problems:
(1) The testcase did not really test if elf64-i386 is supported by GDB (BFD).
That was OK for a Fedora testcase but I forgot about it when submitting it
upstream.
I haven't really verified if the GNU target is elf64-little but it seems so,
no other one seems suitable from:
elf32-x86-64
elf64-big
elf64-k1om
elf64-l1om
elf64-little
elf64-x86-64
pei-x86-64
(2) The output of the "core-file" command itself can be arbitrary as the
elf64-i386 file with x86_64 registers is really broken; but that does not
matter much, important is the following test whether core file memory is
readable.
./configure --enable-64-bit-bfd
(gdb) core-file /home/jkratoch/redhat/gdb-test-build32-plus64/gdb/testsuite/gdb.arch/i386-biarch-core.core^M

x/i 0x400078^M
0x400078: hlt ^M
(gdb) PASS: gdb.arch/i386-biarch-core.exp: .text is readable
I do not know much dejagnu but I expect 'istarget' tests against the site.exp
'target_triplet' content which is set to the primary GDB target
(--target=...).
GDB is normally never configured for primary target elf64-i386, I think BFD
does not know such explicit target, it gets recognized as elf64-little.
In fact many testfiles of the GDB testsuite are wrong as they require
'istarget' (therefore primary GDB target) even for just loading arch specific
files which would be sufficient with secondary target (--enable-targets=...)
support.
This my new patch removes this 'istarget' check as it is IMO unrelated to what
we need to test. Although you are right we do 'x/i' and test for 'hlt' so
I think we should test also for available 'set architecture i386'.
We could also test by 'x/bx' instead of 'x/i' to avoid such additional
test/requirement.
This testcase comes from a different bug from 2009:
https://bugzilla.redhat.com/show_bug.cgi?id=457187
http://pkgs.fedoraproject.org/cgit/gdb.git/commit/?id=94cd124608bf0dd359cb48a710800d72c21b30c3
That bug has been fixed in the meantime but the same testcase was reproducing
this new different bug - internal error regression - so I submitted it.
We can remove the "x/bx $address" test but it was useful for the previous bug
from 2009 as that time the internal error regression did not happen, just the
core file was not recognized (which would not be detected by the proposed
ignoring of the "core-file" command output) and so the core file was not
available. That can be tested by the "x/bx $address" test.

I noticed two failure in gdb.trace/mi-trace-frame-collected.exp:
FAIL: gdb.trace/mi-trace-frame-collected.exp: live:
-trace-frame-collected (register)
FAIL: gdb.trace/mi-trace-frame-collected.exp: tfile:
-trace-frame-collected (register)
In these cases, we are not collecting registers so the MI command
-trace-frame-collected should only give us the value of the PC.
However, it also gives us all of the single precision pseudo registers,
initialized with 0x0.
We can reproduce this error by simply issuing the
'maint print cooked-register' when no inferior is connected:
~~~
...
(gdb) maint print cooked-register
Name Nr Rel Offset Size Type Cooked value
x0 0 0 0 8 long <unavailable>
x1 1 1 8 8 long <unavailable>
...
d30 130 62 1540 8 *1 <unavailable>
d31 131 63 1548 8 *1 <unavailable>
s0 132 64 1556 4 *1 0x00000000
s1 133 65 1560 4 *1 0x00000000
s2 134 66 1564 4 *1 0x00000000
...
s28 160 92 1668 4 *1 0x00000000
s29 161 93 1672 4 *1 0x00000000
s30 162 94 1676 4 *1 0x00000000
s31 163 95 1680 4 *1 0x00000000
h0 164 96 1684 2 *1 <unavailable>
h1 165 97 1686 2 *1 <unavailable>
h2 166 98 1688 2 *1 <unavailable>
...
~~~
It turns out GDB does not check if S registers are valid before returning
a value for them. It should return <unavailable> in this case.
gdb/ChangeLog:
* aarch64-tdep.c (aarch64_pseudo_read_value): Mark S register as
unavailable if invalid.

ari, btrace: avoid unsigned long long
Fix the ARI warning about the use of unsigned long long. We can't use
ULONGEST as this is defined unsigned long on 64-bit systems. This will
result in a compile error when storing a pointer to an unsigned long long

Use size_t to hold the buffer size inside GDB and __u64 when interfacing the

Remove CHECK_TYPEDEF, use check_typedef instead
I think that the CHECK_TYPEDEF macro is not necessary, and even a bit
annoying. It makes unclear the fact that the "type" variables gets
overwritten. It has actually bitten me a few times. I think the
following, explicit form, is better.
type = check_typedef (type);
This patches changes all instances of CHECK_TYPEDEF for an equivalent
call to check_typedef. The bulk of the change was done with this sed:
sed -i 's/CHECK_TYPEDEF (\([^)]*\));/\1 = check_typedef (\1);/' <file>.c
The ChangeLog was generated using David Malcom's generate_changelog.py.
I manually fixed those places where it gets the wrong function name,
hopefully all of them.
The patch was built-tested, and I ran a few smoke tests.

Make default compression gABI compliant
All programs in binutils+gdb git repo now support gABI compression
with the SHF_COMPRESSED bit. This patch makes the zlib-gabi option
as compression default for gas, gold, ld and objcopy, instead of the
zlib-gnu option whose outputs are incompatible with gABI.

* objcopy.c (copy_file): Set BFD_COMPRESS_GABI if not
zlib-gnu.

--compress-debug-sections=zlib to zlib-gabi.

* compressed_output.cc (Output_compressed_section::set_final_data_size):

* testsuite/Makefile.am (flagstest_compress_debug_sections.check):
Expect ".debug_.*" with the SHF_COMPRESSED bit, instead of
".zdebug_".
* testsuite/Makefile.in: Regenerated.

Add test that exercises the inferior being killed while stopped under GDB
This exercises the case of the inferior disappearing while GDB is

Fix attach-pie-noexec.exp fail on native-extended-gdbserver
When I examine the buildbot fails, I see this fail on
native-extended-gdbserver,
Attaching to process 13529^M
"target:/scratch/yao/gdb/build-git/x86_64/gdb/testsuite/gdb.base/attach-pie-noexec (deleted)": could not open as an executable file: No such file or directory^M
(gdb) FAIL: gdb.base/attach-pie-noexec.exp: attach

Attaching to process 13869^M
/scratch/yao/gdb/build-git/x86_64/gdb/testsuite/gdb.base/attach-pie-noexec (deleted): No such file or directory.^M
(gdb) PASS: gdb.base/attach-pie-noexec.exp: attach
the test expects to see the period at the end of the error message,
gdb_test "attach $testpid" "Attaching to process $testpid\r\n.*: No such file or directory\\." "attach"
however the period is missing when running with native-extended-gdbserver.
in exec.c:exec_file_attach, GDB has two places may throw errors [1] and [2],
if (load_via_target)
{
...
}
else
{
...
if (scratch_chan < 0)
perror_with_name (filename); <--- [1]
}
...
if (!exec_bfd)
{
error (_("\"%s\": could not open as an executable file: %s"), <-- [2]
scratch_pathname, bfd_errmsg (bfd_get_error ()));
}
perror_with_name [1] append a period at the end of error message,
but error [2] doesn't. This fix is to add a period at the end of the
error message. Note that this fail is shown up on 7.9 release as well.

The output SHF_COMPRESSED section size is different from input if
ELF classes of input and output aren't the same. We must adjust
the section sizes as well as the compression headers in
SHF_COMPRESSED sections when converting objects between different
ELF classes.

rx-tdep.c: Use target_read_code instead of target_read_memory.
This change causes the prologue scanner and the frame type scanner in
rx-tdep.c to use target_read_code() instead of target_read_memory().
This change allows these instruction scanners to operate much more
quickly due to the fact that target_read_code() can potentially read
from a cache maintained by GDB.

gdbserver/event-loop.c: type mismatch
Building with C++ catches a buglet here:
../../../src/gdb/gdbserver/event-loop.c:205:19: warning: invalid conversion from ‘gdb_client_data {aka void*}’ to ‘void**’ [-fpermissive]
event_ptr->data = data;
^
This works in practice because gdb_client_data is a pointer already
(hence in C we get an implicit conversion), and nothing deferences the
pointer. It's passed from client at event registration/creation time,
only to pass straight back to client callback.
Well, that and nothing in gdbserver uses the event data anyway.

record: set stop_pc in "record goto" command
When navigating in the recorded execution trace via "record goto", we do not
set stop_pc. This may trigger an internal error in infrun.c when stepping
from that location. Set it.

Continuing.
Breakpoint 1, foo (void) at foo.c:42

infrun.c:2382: internal-error: resume: Assertion `sig != GDB_SIGNAL_0' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
This happens because there's a breakpoint at PC when the "next"
is issued, so that breapoint should be immediately stepped over.
That should have been detected/done by proceed, here:
if (addr == (CORE_ADDR) -1)
{
if (pc == stop_pc
&& breakpoint_here_p (aspace, pc) == ordinary_breakpoint_here
&& execution_direction != EXEC_REVERSE)
/* There is a breakpoint at the address we will resume at,
step one instruction before inserting breakpoints so that
we do not stop right away (and report a second hit at this
breakpoint).
Note, we don't do this in reverse, because we won't
actually be executing the breakpoint insn anyway.
We'll be (un-)executing the previous instruction. */
tp->stepping_over_breakpoint = 1;
But since stop_pc was stale, the pc == stop_pc check failed, and left the
breakpont at PC inserted.

Drop 'missing mapping symbols' warning for arm and aarch64.
The psABI (AAELF) says this about mapping symbols:
4.6.5.1 Section-relative mapping symbols
Mapping symbols defined in a section define a sequence of
half-open address intervals that cover the address range of the
section. Each interval starts at the address defined by the
mapping symbol, and continues up to, but not including, the
address defined by the next (in address order) mapping symbol or
the end of the section. A section must have a mapping symbol
defined at the beginning of the section; however, if the section
contains only data then the mapping symbol may be omitted.
That makes it pretty clear that, in the absence of a mapping symbol,
the entire section can be treated as data.

* aarch64.cc (AArch64_relobj::scan_errata): Drop missing symbol warning.
* arm.cc (Arm_relobj::scan_section_for_cortex_a8_erratum): Drop missing

[AArch64] Teach stub unwinder to terminate gracefully
The stub unwinder is used on AArch64 if the target's memory is not
readable at the current PC. For example, the user could try to call at
an invalid address such as 0x0, as covered in the gdb.base/signull.exp
test case. Many GDB ports use a similar unwinder to handle this case
too.
If we purposely kill the inferior before examining the trace then we get
the following issue:
~~~
...
(gdb) trace f
Tracepoint 3 at 0x7fb7fc28c0
(gdb) tstart
(gdb) continue
...
(gdb) tstop
(gdb) tsave /tmp/trace
(gdb) kill
...
(gdb) target tfile /tmp/trace
...
(gdb) tfind
Register 31 is not available.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Found trace frame 0, tracepoint 3
#-1 0x0000007fb7fc28c0 in f () ...
^^^
~~~
This patch teaches the stub unwinder to report to the core frame code
with UNWIND_UNAVAILABLE when either the stack pointer of the return
address are unavailable to read from the target.
gdb/ChangeLog:
* aarch64-tdep.c (aarch64_make_stub_cache): Set available_p and

[AArch64] Teach prologue unwinder to terminate gracefully
Without debugging information, we have the following issue when
examining a trace buffer:
~~~
...
(gdb) trace f
Tracepoint 3 at 0x7fb7fc28c0
(gdb) tstart
(gdb) continue
...
(gdb) tstop
(gdb) tfind start
Register 31 is not available.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Found trace frame 0, tracepoint 3
#-1 0x0000007fb7fc28c0 in f () ...
^^^
~~~
The reason for this is that the target's stack pointer is unavailable
when examining the trace buffer. What we are seeing is due to the
'tfind' command creating a sentinel frame and unwinding it. If an
exception is thrown, we are left with the sentinel frame being displayed
at level #-1. The exception is thrown when the prologue unwinder tries
to read the stack pointer to construct an ID for the frame.
This patch fixes this by making the prologue unwinder catch
NOT_AVAILABLE_ERROR exceptions when either registers or memory is
unreadable and report back to the frame core code with
UNWIND_UNAVAILABLE.
gdb/ChangeLog:
* aarch64-tdep.c (aarch64_prologue_cache) <available_p>: New

[gdbserver, aarch64] Set usrregs to NULL in regs_info
Hi,
I happen to read the comments in regs_info below,
struct regs_info
{
...
/* Info used when accessing registers with PTRACE_PEEKUSER /
PTRACE_POKEUSER. This can be NULL if all registers are
transferred with regsets .*/
struct usrregs_info *usrregs;
that usrregs can be NULL if all registers are transferred with
regsets, which is exactly what aarch64-linux does. This patch
is to set usrregs to NULL in regs_info and remove
aarch64_usrregs_info and aarch64_regmap.

Delete program spaces directly when removing inferiors
When deleting an inferior, delete the associated program space as well
if it becomes unused. This replaces the "pruning" approach, with which
you could forget to call prune_program_spaces (as seen, with the
-remove-inferior command, see [1]).
This allows to remove the prune_program_spaces function. At the same
time, I was able to clean up the delete_inferior* family:
- delete_inferior is unused
- delete_inferior_silent is only used in monitor_close, but is replaced
with discard_all_inferiors [2], so it becomes unused
- All remaining calls to delete_inferior_1 are with silent=1, so the
parameter is removed
- delete_inferior_1 is renamed to delete_inferior
I renamed pspace_empty_p to program_space_empty_p. I prefer if the
"exported" functions have a more explicit and standard name.
Tested on Ubuntu 14.10.

PR18617 - Incorrect expression bytecode generated for narrowing conversions
The existing code preserves 'from' bits, which is incorrect. E.g.
(gdb) maint agent-eval (char)255L
Scope: 0x4008d6
Reg mask: 00
0 const16 255
3 ext 64
5 end
'ext 64' should be 'ext 8'; this bytecode evaluates to 255 instead of
the correct result of -1. The fix is simple. I ran the entire test
suite on x86-64 and there were no new test failures.

New proc is_aarch32_target
GDB tests running on arm target should be also run on aarch32
(32-bit mode on aarch64). There should be no difference. It is not
precise to check target triplet to decide which tests should be run,
because if I compiler all the test binary in 32-bit (arm program),
but target triplet is still aarch64, so that these arm specific tests
are skipped.
This patch is to add a new proc is_aarch32_target which return true
if target triplet is arm or the test binary is compiled for arm.

Adjust gdb.multi tests for aarch64
Multi-arch related tests under gdb.multi are to compile programs with
the same compiler but different compiler options (-m64 vs -m32). However,
different compilers are needed to compile both aarch64 program and
arm (aarch32) program. This patch is to adjust these test cases to
compile programs in different modes with different compiler.
When we use gcc for arm-linux target, its file name can be different,
arm-linux-gnueabihf-gcc, arm-linux-gnueabi-gcc, or arm-none-linux-gnueabi-gcc,
so I add a variable ARM_CC_FOR_TARGET, so that user can set the name
of gcc for arm-linux target on aarch64, like:
$ make check RUNTESTFLAGS='ARM_CC_FOR_TARGET=arm-linux-gnueabihf-gcc multi-arch.exp'

Set architecture to arm in arm-*.xml files
This patch is to add the following line to various arm target description
xml files,
<architecture>arm</architecture>
in order to fix problems I've seen on aarch64 multi-arch debugging,
detach^M
Detaching from program: build-gdb/gdb/testsuite/gdb.base/attach, process 17145^M
(gdb) PASS: gdb.base/attach.exp: attach1 detach file^M
No executable file now.^M
Architecture of file not recognized.^M
(gdb) FAIL: gdb.base/attach.exp: attach1, purging symbols after detach
Without this patch, struct target_desc *tdesc_* are not initialised
properly, that is, fields arch and osabi in 'struct target_desc' are
not set properly. This doesn't cause any problems on single arch
debugging, because arch-utils.c:gdbarch_info_fill will guess correctly.
However, in multi-arch debugging, gdbarch_info_fill gets the aarch64
arch, but the target description is for arm (because the current
inferior is 32-bit arm).
It is a surprise to me we didn't set architecture to "arm" before in *.xml
files, and I didn't find out why didn't do so. AFAICS,
gdb/features/arm-with-iwmmxt.xml was added firstly (in patch
https://sourceware.org/ml/gdb-patches/2007-01/msg00593.html)
which had <architecture>iwmmxt</architecture>, however, afterwards,
architecture isn't set anymore in features/arm-*.xml files (in patches

Native debug arm program by aarch64 GDB
This patch is to let aarch64 GDB debug 32-bit arm program natively. In
each function for fetching and storing registers, GDB will check
gdbarch_bfd_arch_info (gdbarch)->bits_per_word, if it is 32, call
the corresponding aarch32 functions in aarch32-linux-nat.c, otherwise
fall back to aarch64 code to fetch and store registers.
aarch64_linux_read_description has to return the right target description,
but we don't have gdbarch available there, so GDB fetches auxv and gets
AT_PHENT, in order to determine whether the target is 32-bit or 64-bit.
I learned this trick from solib-svr4.c.

[arm] Fix regression by Do not skip prologue for asm (.S) files
Patch "Do not skip prologue for asm (.S) files" [1] changes GDB's
behaviour on which test gdb.arch/thumb-singlestep.exp depends, so
it causes the fail below:
(gdb) si^M
37 blx foo^M
(gdb) FAIL: gdb.arch/thumb-singlestep.exp: step into foo
the test assumes the program will stop at the instruction after "push"
but it doesn't. The fix to this fail is to do one more single step.

gdb: Rewrite documentation for layout and focus commands.
Changes the documentation for the layout and focus commands.
Instead of documenting each layout (or focus) sub-command as a separate
command, document a single layout (and focus) command which takes a
parameter, then list the possible parameters in a table nested under
each command.
The documentation for the layout command has been extended little to

Remove ppc860, ppc750cl, ppc7450 insns from common ppc.
Back in the day support for these processors was added, we probably
didn't want to waste PPC_OPCODE bits on minor variations. I've had a
complaint that disassembly of mfspr/mtspr was wrong for power8. This
patch fixes that problem.
Note that since -m860/-m850/-m821 are new gas options enabling the
mpc8xx specific mfspr/mtspr variants it is possible that this change
will break some mpc8xx assembly code. ie. you might need to modify
makefiles to pass -m860 to gas.

Add support for backtracing through Renesas RX exception frames.
This change adds support for backtracing through Renesas RX exception
frames.
Determination about the type of frame is made by scanning the
remainder of the function for a return instruction and then looking at
which, if any, return instruction is found. A normal RTS instruction
indicates that the frame is a normal frame. An RTFI instruction
indicates that it's a fast interrupt, and an RTE instruction indicates
that the frame is a (normal) exception frame. If no return instruction
is found within the scanned region - which can happen when the end of
the function cannot be found - it is assumed to be a normal frame.
I was able to test that normal prologue scanning still works by
disabling the dwarf2 sniffer. I've tested this code for normal
interrupts. The fast interrupt case has not been tested.
gdb/ChangeLog:
* rx-tdep.c (RX_USP_REGNUM, RX_BPC_REGNUM): New constants.
(enum rx_frame_type): New.

`this_cache'. Add cases for RX_FRAME_TYPE_EXCEPTION and
RX_FRAME_TYPE_FAST_INTERRUPT.

TUI: Make sure to update registers if frame information has changed
When I replaced TUI's frame_changed hook to fix PR tui/13378 I assumed
that there's no reason to refresh register information following a call
to "up", "down" or "frame". This assumption was made to fix the problem
of refreshing frame information twice following a sync-execution normal
stop (once in tui_normal_stop and then in tui_before_prompt) -- the
second refresh removing any highlights made by the first.
I was wrong about that -- GDB's snapshot of register information is
per-frame, and when the frame changes, registers do too (most
prominently the %rip and %rsp registers). So e.g. GDB 7.8 would
highlight such register changes after invoking "up", "down" or "frame",
and current GDB does not.
To fix this regression, this patch adds another (sufficient) condition
for refreshing register information: in
tui_refresh_frame_and_register_information, always refresh register
information if frame information has changed. This makes register
information get refreshed following a call to "up", "down" or "frame"
while still avoiding the "double refresh" issue following a normal stop.
This condition may seem to obsolete the existing registers_too_p
parameter, but it does not: following a normal stop, it is possible that
registers may have changed while frame information had not. We could be
on the exact same PC with different register values. The new condition
would not catch such a case, but the registers_too_p condition will. So
both conditions seem necessary (and either one is sufficient).
gdb/ChangeLog:
* tui/tui-hooks.c (tui_refresh_frame_and_register_information):
Update commentary. Always refresh the registers when frame
information has changed.
* tui/tui-stack.c (tui_show_frame_info): Update commentary.
Change return type to int. Return 1 if frame information has
changed, 1 otherwise.

* tui/tui-stack.h (tui_show_frame_info): Change return type to

Replace TUI's select_frame hook (PR tui/13378)
The select_frame hook is used by TUI to update TUI's frame and register
information following changes to the selected frame. The problem with
this hook is that it gets called after every single frame change, even
if the frame change is only temporary or internal. This is the primary
cause of flickering and slowdown when running the inferior under TUI
with conditional breakpoints set. Internal GDB events are the source of
many calls to select_frame and these internal events are triggered
frequently, especially when a few conditional breakpoints are set.
This patch removes the select_frame hook altogether and instead makes
the frame and register information get updated in two key places (using
observers): after an inferior stops, and right before displaying a
prompt. The latter hook covers the case when frame information must be
updated following a call to "up", "down" or "frame", and the former
covers the case when frame and register information must be updated
after a call to "continue", "step", etc. or after the inferior stops in
async execution mode. Together these hooks should cover all the cases
when frame information ought to be refreshed (and when the relevant
windows ought to be subsequently updated).
The print_frame_info_listing hook is also effectively obsolete now, but
it still must be set while the TUI is active because its caller
print_frame_info will otherwise assume that the CLI is active, and will
print the frame informaion accordingly. So this patch also sets the
print_frame_info_listing hook to a dummy callback, in lieu of outright
removing it yet.
Effectively, with this patch, frame/PC changes that do not immediately
precede an inferior-stop event or a prompt display event no longer cause
TUI's frame and register information to be updated.
And as a result of this change and of the previous change to
tui_show_frame_info, the TUI is much more disciplined about updating the
screen, and so the flicker as described in the PR is totally gone.

Be lazy about refreshing the windows in tui_show_frame_info (PR tui/13378)
tui_show_frame_info is responsible for updating the visible windows
following a change in frame information (that being the currently
selected frame, PC, line number, etc). Currently it always redraws and
refreshes each window even if frame information has not changed. This
behavior is inefficient and helps contribute to the occassional
flickering of the TUI as described in the mentioned PR.
This patch makes tui_show_frame_info refresh the windows only if frame
information has changed. Determining whether frame information has
changed is done indirectly by determining whether the locator has
changed. This approach is convenient and yet sensible because the
locator contains all the relevant info we need to check anyway: the
current PC, the line number, the name of the executable and the name of
the current function. Probably only the PC is really necessary to
check, but it doesn't hurt to check every field.
Effectively, with this patch, consecutive calls to select_frame with the
same frame/PC no longer cause TUI's frame information to be updated
multiple times.
gdb/ChangeLog:
PR tui/13378
* tui/tui-stack.c (tui_set_locator_info): Change prototype to
return an int instead of void. Return whether the locator

Correctly initialize the TUI locator window
The call to tui_alloc_content in tui_set_locator_info passes
locator->type as the type of the window whose content is being
allocated. This may seem correct but it's actually not because when
this code path actually get executed locator->type has not yet been to
set LOCATOR_WIN so it defaults to 0 i.e. SRC_WIN. Thus we allocate the
content of the locator window as if it was the source window. This
oversight turns out not to be a big deal in practice but the patch that
follows depends on the locator's proc_name and full_name arrays to be
initialized to the empty string which is done by tui_alloc_content if
we pass to it LOCATOR_WIN.
This patch fixes this bug by explicitly passing LOCATOR_WIN to
tui_alloc_content.

* tui/tui-stack.c (tui_set_locator_info): Explicitly pass

PR threads/18127 - threads spawned by infcall end up stuck in "running" state
Refs:
https://sourceware.org/ml/gdb/2015-03/msg00024.html
https://sourceware.org/ml/gdb/2015-06/msg00005.html
On GNU/Linux, if an infcall spawns a thread, that thread ends up with
stuck running state. This happens because:
- when linux-nat.c detects a new thread, it marks them as running,
and does not report anything to the core.
- we skip finish_thread_state when the thread that is running the
infcall stops.
As result, that new thread ends up with stuck "running" state, even
though it really is stopped.
On Windows, _all_ threads end up stuck in running state, not just the
one that was spawned. That happens because when a new thread is
detected, unlike linux-nat.c, windows-nat.c reports
TARGET_WAITKIND_SPURIOUS to infrun. It's the fact that that event
does not cause a user-visible stop that triggers the problem. When
the target is re-resumed, we call set_running with a wildcard ptid,
which marks all thread as running. That set_running is not suppressed
because the (leader) thread being resumed does not have in_infcall
set. Later, when the infcall finally finishes successfully, nothing
marks all threads back to stopped.
We can trigger the same problem on all targets by having a thread
other than the one that is running the infcall report a breakpoint hit
to infrun, and then have that breakpoint not cause a stop. That's
what the included test does.
The fix is to stop GDB from suppressing the set_running calls while
doing an infcall, and then set the threads back to stopped when the
call finishes, iff they were originally stopped before the infcall
started. (Note the MI *running/*stopped event suppression isn't
affected.)
Tested on x86_64 GNU/Linux.

[GDBServer][AArch64] Use the same break instruction as GDB
GDB uses a "brk #0" instruction to perform a software breakpoint while
GDBServer uses an illegal instruction. Both instructions should match.
When enabling support for the 'Z0' packet, we let GDBServer insert the
breakpoint instruction instead of GDB. And in case of permanent
breakpoints for example, GDB will check if a breakpoint is inserted in the
inferior with `program_breakpoint_here_p (gdbarch, address)', and
compare the instruction read from the inferior with the breakpoint
instruction.
On AArch64, instructions are always little endian so we need to
represent it as an array of bytes, as done in aarch64-tdep.c.
gdb/gdbserver/ChangeLog:
* linux-aarch64-low.c: Remove comment about endianness.
(aarch64_breakpoint): Change type to gdb_byte[]. Set to "brk #0".
(aarch64_breakpoint_at): Change type of insn to gdb_byte[]. Use
memcmp.

PR 16253 revisited
Last year a patch was submitted/approved/commited to eliminate
symbol_matches_domain which was causing this problem. It was later reverted
because it introduced a (severe) performance regression.
Recap:
(gdb) list
1 enum e {A,B,C} e;
2 int main (void) { return 0; }
3
(gdb) p e
Attempt to use a type name as an expression
The parser attempts to find a symbol named "e" of VAR_DOMAIN.
This gets passed down through lookup_symbol and (eventually) into
block_lookup_symbol_primary, which iterates over the block's dictionary
of symbols:
for (sym = dict_iter_name_first (block->dict, name, &dict_iter);
sym != NULL;
sym = dict_iter_name_next (name, &dict_iter))
{
if (symbol_matches_domain (SYMBOL_LANGUAGE (sym),
SYMBOL_DOMAIN (sym), domain))
return sym;
}
The problem here is that we have a symbol named "e" in both STRUCT_DOMAIN
and VAR_DOMAIN, and for languages like C++, Java, and Ada, where a tag name
may be used as an implicit typedef of the type, symbol_matches_domain ignores
the difference between VAR_DOMAIN and STRUCT_DOMAIN. As it happens, the
STRUCT_DOMAIN symbol is found first, considered a match, and that symbol is
returned to the parser, eliciting the (now dreaded) error message.
Since this bug exists specifically because we have both STRUCT and VAR_DOMAIN
symbols in a given block/CU, this patch rather simply/naively changes
block_lookup_symbol_primary so that it continues to search for an exact
domain match on the symbol if symbol_matches_domain returns a symbol
which does not exactly match the requested domain.
This "fixes" the immediate problem, but admittedly might uncover other,
related bugs. [Paranoia?] However, it causes no regressions (functional
or performance) in the test suite. A similar change has been made
to block_lookup_symbol for other cases in which this bug might appear.
The tests from the previous submission have been resurrected and updated.
However since we can still be given a matching symbol with a different domain
than requested, we cannot say that a symbol "was not found." The error
messages today will still be the (dreaded) "Attempt to use a type name..."
ChangeLog

continue to search for a symbol with an exact domain match

Add option to remove duplicate command history entries
This patch implements the new option "history remove-duplicates", which
controls the removal of duplicate history entries ("off" by default).
The motivation for this option is to be able to reduce the prevalence of
basic commands such as "up" and "down" in the history file. These
common commands crowd out more unique commands in the history file (when
the history file has a fixed size), and they make navigation of the
history file via ^P, ^N and ^R more inconvenient.
The option takes an integer denoting the number of history entries to
look back at for a history entry that is a duplicate of the latest one.
"history remove-duplicates 1" is equivalent to bash's ignoredups option,
and "history remove-duplicates unlimited" is equivalent to bash's
erasedups option.
[ I decided to go with this integer approach instead of a tri-state enum
because it's slightly more flexible and seemingly more intuitive than
leave/erase/ignore. ]
gdb/ChangeLog:
* NEWS: Mention the new option "history remove-duplicates".
* top.c (history_remove_duplicates): New static variable.
(show_history_remove_duplicates): New static function.
(gdb_add_history): Conditionally remove duplicate history
entries.

Add tab completion for TUI's "focus" command
The implementation is pretty straightforward, with the only caveat being
that the "src", "cmd", "next" and "prev" entries get delibrately added
to the completion list even when the TUI has not yet been initialized
(i.e. has never been enabled during the session), since invoking the
"focus" command with these arguments already works when the TUI has not
yet been initialized.

Do not skip prologue for asm (.S) files
GDB tries to skip prologue for .S files according to .debug_line but it then
places the breakpoint to a location where it is never hit.
This is because #defines in .S files cause prologue skipping which is
completely inappropriate, for s390x:
glibc/sysdeps/unix/syscall-template.S
78:/* This is a "normal" system call stub: if there is an error,
79: it returns -1 and sets errno. */

without debuginfo or with debuginfo and the fix - correct address:

Breakpoint 1 at 0xf4210
It is also where .dynsym+.symtab point to:
00000000000f4210 T __select
00000000000f4210 W select
with debuginfo, without the fix:
(gdb) b select
Breakpoint 1 at 0xf41c8: file ../sysdeps/unix/syscall-template.S, line 81.
One part is to behave for asm files similar way like for 'locations_valid':
/* Symtab has been compiled with both optimizations and debug info so that
GDB may stop skipping prologues as variables locations are valid already
at function entry points. */
unsigned int locations_valid : 1;
The other part is to extend the 'locations_valid'-like functionality more.

gdb: sim: handle target sysroot prefix
The default gdb sysroot now sets itself to "target:". This works for
most remote targets, but when using the simulator, this causes problems
as the sim will attempt to search for that path.
Update the remote-sim logic to skip this leading prefix when it is found
so that the sysroot isn't passed in as an invalid value.

Fix GDBHISTSIZE test failure on i686
The test
test_histsize_history_setting "99999999999999999999999999999999999" "unlimited"
was failing on i686 because the condition in init_history() for
determining whether to map a large GDBHISTSIZE value to infinity was
long var = strtol (tmpenv);
if (var > INT_MAX)
history_size = unlimited;
but this condition is never true on i686 because INT_MAX == LONG_MAX.
So in order to properly map large out-of-range values of GDBHISTSIZE to
infinity on targets where LONG_MAX > INT_MAX as well as on i686, we have
to instead change the above condition to
if (var > INT_MAX
|| (var == INT_MAX && errno == ERANGE))
history_size = unlimited;
gdb/ChangeLog:
* top.c (init_history): Look at errno after calling strtol to
properly map large GDBHISTSIZE values to infinity.

There is a slight nuance related to colons, but it's not clear what the

Convert have_ptrace_getregset to a tri-state boolean
have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have
some conditions like "if (have_ptrace_getregset)", which is not correct.
I'll explain why it is not correct in the following example. This fix
to this problem to replace the test (have_ptrace_getregset) to test
(have_ptrace_getregset == 1) or (have_ptrace_getregset == -1) etc.
However Doug thinks it hinders readability
https://sourceware.org/ml/gdb-patches/2015-05/msg00692.html so I decide
to add a new enum tribool and change have_ptrace_getregset to it, in
order to make these tests more readable.
have_ptrace_getregset is initialised to -1, and is adjusted to 0 or 1 in
$ARCH_linux_read_description according to the capability of the kernel.
However, it is possible that have_ptrace_getregset is used before it is
set to 0 or 1, which means it is still -1. This is shown below.

PPC sync instruction accepts invalid and incompatible operands
ISA 2.07 added a new category called Elemental Memory Barriers that modifies
the sync instruction to accept an additional operand ESYNC. Edmar added
support for this insruction varient here:
https://sourceware.org/ml/binutils/2012-02/msg00221.html
Looking at this closer, I see that the insert_ls() function is misnamed
(since it's attached to the ESYNC operand, not the LS operand) but more
importantly, it is silently modifying the LS operand value behind the
users back when the LS operand is either invalid or is incompatible with
the new ESYNC operand. The ISA 2.07 doc has an Assembler Note that clearly
states that assemblers that support the ESYNC operand should report all
invalid uses of LS and ESYNC. This patch changes the assembler to
error out on invalid and incompatible operand usage.

Stop "objdump -d" from disassembling past a symbolic address.
include * dis-asm.h (struct disassemble_info): Add stop_vma field.
binuti * objdump.c (disassemble_bytes): Set the stop_vma field in the
disassemble_info structure when disassembling code sections with
-d.
* doc/binutils.texi (objdump): Document the discrepancy between -d
and -D.
opcodes * dis-buf.c (buffer_read_memory): Fail is stop_vma is set and the
requested region lies beyond it.
* bfin-dis.c (print_insn_bfin): Ignore sysop instructions when
looking for 32-bit insns.
* mcore-dis.c (print_insn_mcore): Disable stop_vma when reading
data.

blocks of instructions.
* vax-dis.c (print_insn_vax): Check that the requested address
does not clash with the stop_vma.
tests * gas/arm/backslash-at.s: Add extra .byte directives so that the
foo symbol does not appear to point half way through an
instruction.
* gas/arm/backslash-at.d: Update expected disassembly.

commit 52042a003f3e9200c992bc5cf4607dc7655b1f7b
Author: Yao Qi <yao.qi@linaro.org>
Date: Mon Jun 22 13:41:33 2015 +0100
Don't skip hw breakpoint/watchpoint tests for aarch64 target
This patch is to let skip_hw_breakpoint_tests and skip_hw_watchpoint_tests
return 0 for aarch64 target, since aarch64 has HW watchpoint and
breakpoint registers.
With this patch applied, about 1560 watchpoint/breakpoint related tests
become enabled on aarch64-linux native testing.
gdb/testsuite:
2015-06-22 Yao Qi <yao.qi@linaro.org>
* lib/gdb.exp (skip_hw_breakpoint_tests): Return 0 for target
aarch64*-*-*.
(skip_hw_watchpoint_tests): Likewise.

Automatic date update in version.in
commit ccd4b2953bb039e91b301a616c5f7c6f542b6b10
Author: Mike Frysinger <vapier@gentoo.org>
Date: Sat Jun 20 15:21:26 2015 +0545
sim: common: add basic model assert
If the configured in default doesn't match a known value, throw an
assertion failure rather than segfaulting deeper down.
commit f55b33d51b056c665568c6204bd3ced7f1ec15c8
Author: Mike Frysinger <vapier@gentoo.org>
Date: Sat Jun 20 09:33:04 2015 +0545
sim: common: use standard intXX_t types for signedXX
Let's assume that the system supports the POSIX int8/16/32/64_t types
as this collapses the logic significantly.
commit 618b526e31d3df71e9526a0753271624a568564e
Author: Mike Frysinger <vapier@gentoo.org>
Date: Sat Jun 20 09:31:10 2015 +0545
sim: common: standardize multiple include defines
We use SIM_xxx_H in most headers, so convert _SIM_xxx_H_ over to it.
