Fix PR gdb/18653: gdb disturbs inferior's inherited signal dispositions

gdb's (or gdbserver's) own signal handling should not interfere with
the signal dispositions their spawned children inherit.  However, it
currently does.  For example, some paths in gdb cause SIGPIPE to be
set to SIG_IGN, and as consequence, the child starts with SIGPIPE to
set to SIG_IGN too, even though gdb was started with SIGPIPE set to
SIG_DFL.

This is because the exec family of functions does not reset the signal
disposition of signals that are set to SIG_IGN:

  http://pubs.opengroup.org/onlinepubs/7908799/xsh/execve.html

  Signals set to the default action (SIG_DFL) in the calling process
  image are set to the default action in the new process
  image. Signals set to be ignored (SIG_IGN) by the calling process
  image are set to be ignored by the new process image. Signals set to
  be caught by the calling process image are set to the default action
  in the new process image (see <signal.h>).

And neither does it reset signal masks or flags.

In order to be transparent, when spawning new child processes to debug
(with "run", etc.), reset signal actions and mask back to what was
originally inherited from gdb/gdbserver's parent, just before execing
the target program to debug.

*** TEST RESULTS FOR COMMIT 3fc6097b073698a50d0ab70c6c8205a83cd9383c ***

Author: Simon Marchi <simon.marchi@ericsson.com>
Branch: gdb-7.12-branch
Commit: 3fc6097b073698a50d0ab70c6c8205a83cd9383c

Fix python-interactive with Python 3.6

New in v2:

 - Define PyMem_RawMalloc as PyMem_Malloc for Python < 3.4 and use
   PyMem_RawMalloc in the code.

Since Python 3.4, the callback installed in PyOS_ReadlineFunctionPointer
should return a value allocated with PyMem_RawMalloc instead of
PyMem_Malloc.  The reason is that PyMem_Malloc must be called with the
Python Global Interpreter Lock (GIL) held, which is not the case in the
context where this function is called.  PyMem_RawMalloc was introduced
for cases like this.

In Python 3.6, it looks like they added an assert to verify that
PyMem_Malloc was not called without the GIL.  The consequence is that
typing anything in the python-interactive mode of gdb crashes the
process.  The same behavior was observed with the official package on
Arch Linux as well as with a manual Python build on Ubuntu 14.04.

This is what is shown with a debug build of Python 3.6 (the error with a
non-debug build is far less clear):

  (gdb) pi
  >>> print(1)
  Fatal Python error: Python memory allocator called without holding the GIL

  Current thread 0x00007f1459af8780 (most recent call first):

Author: Yao Qi <yao.qi@linaro.org>
Branch: gdb-7.12-branch
Commit: e2285602341fff057a9b4687b465a9d9cde1303f

Throw SJ/LJ exception on error in disassembly

PR 20939 reports that GDB will abort on memory error in disassembly,

(gdb) disassemble 0x0,+4
Dump of assembler code from 0x0 to 0x4:
terminate called after throwing an instance of 'gdb_exception_RETURN_MASK_ERROR'
   0x0000000000000000:	Aborted

(gdb) guile (print (arch-disassemble arch 0 #:size 4))^M
terminate called after throwing an instance of 'gdb_exception_RETURN_MASK_ERROR'^M
ERROR: Process no longer exists

This patch fixes PR 20939 by catching C++ exception, throwing SJ/LJ
exception in the call back passed to C functions of opcodes, and
catching SJ/LJ exception in gdb, and throw exception.

The patch follows this commit

 89525768cd086a0798a504c81fdf7ebcd4c904e1
 Propagate GDB/C++ exceptions across readline using sj/lj-based TRY/CATCH

rather than "backport" the fix to this PR I posted for mainline
https://sourceware.org/ml/gdb-patches/2017-01/msg00288.html because the
fix for mainline includes 1) some changes to opcodes, 2) some refactors
in C++.  All of them are risky to backport to 7.12 branch.

With this patch applied to 7.12 branch, GDB doesn't abort on memory error
in disassembly.  It fixes some test failures in gdb.guile/scm-disasm.exp
and gdb.python/py-arch.exp on aarch64-linux.

-ERROR: Process no longer exists
-UNRESOLVED: gdb.guile/scm-disasm.exp: test bad memory access
+PASS: gdb.guile/scm-disasm.exp: test bad memory access

-ERROR: Process no longer exists
-UNRESOLVED: gdb.python/py-arch.exp: test bad memory access
+PASS: gdb.python/py-arch.exp: test bad memory access

I'll add the scm-disasm test to master later.

gdb: Fix C and C++03 builds

The readline/sjlj-exceptions fix added an unconditional use of
noexcept, but that's only valid C++11, and 7.12 must build with C and
C++03 too.  Fix this by adding a GDB_EXCEPT macro that compiles away
to nothing in C, and to throw() in C++03, which I've confirmed fixes
the original issue just the same as noexcept, with GCC 7 + -std=gnu+03
+ sjlj-exceptions.

Commit: ada8ff522ce970e11dae4a3463c899b64e6f5006

Fix longjmp across readline w/ --enable-sjlj-exceptions toolchains

Nowadays, GDB propagates C++ exceptions across readline using
setjmp/longjmp 89525768cd08 ("Propagate GDB/C++ exceptions across
readline using sj/lj-based TRY/CATCH") because DWARF-based unwinding
can't cross C functions compiled without -fexceptions (see details
from the commit above).

Unfortunately, toolchains that use SjLj-based C++ exceptions got
broken with that fix, because _Unwind_SjLj_Unregister, which is put at
the exit of a function, is not executed due to the longjmp added by
that commit.

_Unwind_SjLj_Register / _Unwind_SjLj_Unregister calls for C++

Remove assert on exec_bfd in cris_delayed_get_disassembler

cris_delayed_get_disassembler has an assert that exec_bfd can't be

A problem internal to GDB has been detected,
further debugging may prove unreliable.

however, cris_get_disassembler does have code to handle the case that
bfd is NULL,

  /* If there's no bfd in sight, we return what is valid as input in all
     contexts if fed back to the assembler: disassembly *with* register
     prefix.  Unfortunately this will be totally wrong for v32.  */

This patch is to remove this assert.

Author: Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE>
Branch: gdb-7.12-branch
Commit: fd5c8f0002f6790d57b6479bc9f2e86ccd63a68b

Fix gdb C++ compilation on Solaris (PR build/20712)

gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried
10 and 12, sparc and x86).  The following patch (relative to the 7.12
release, though I expect most if not all issues to be present on trunk,
too) fixes this.

Only a few of the changes bear explanation:

* Initially, compilation failed whereever defs.h. was included:

In file included from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:0:
/vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:630:33: error: 'double atof(const char*)' conflicts with a previous declaration
 extern double atof (const char *); /* X3.159-1989  4.10.1.1 */
                                 ^

                 from build-gnulib/import/stdlib.h:36,
                 from /vol/src/gnu/gdb/gdb-7.12/gdb/common/common-defs.h:32,
                 from /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:28,
                 from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:
/vol/gcc-4.9/lib/gcc/i386-pc-solaris2.10/4.9.0/include-fixed/iso/stdlib_iso.h:119:15: note: previous declaration 'double std::atof(const char*)'
 extern double atof(const char *);
               ^

  This is due to this gem in gdb/defs.h which seems to have been present
  like forever:

#ifndef atof
extern double atof (const char *);	/* X3.159-1989  4.10.1.1 */
#endif

  In the Solaris headers, the appropriate functions are in namespace std,
  thus the conflict.  I've wrapped the defs.h declaration in !__cplusplus
  to avoid this; perhaps it can go completely instead.

* All the casts are necessary to appease g++ and should be pretty
  obvious.

* The sol-thread.c changes are here to handle

/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()':
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive]
   if (!(p_##X = dlsym (dlhandle, #X))) \
                                    ^
/vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1255:3: note: in expansion of macro 'resolve'
   resolve (td_log);
   ^

  and are modeled after linux-thread-db.c (try_thread_db_load_1).

The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10
and i386-pc-solaris2.10 to complete.  The resulting binary hasn't seen
more than a smoke test (invoke it on itself, b main, run) yet.

When investigating the failure to detect -static-libstdc++
support (more below), I found two more issues which only show up with
-Werror:

/vol/src/gnu/gdb/gdb/local/gdb/procfs.c: In function 'ssd* proc_get_LDT_entry(procinfo*, int)':
/vol/src/gnu/gdb/gdb/local/gdb/procfs.c:2487:19: error: variable 'old_chain' set but not used [-Werror=unused-but-set-variable]
   struct cleanup *old_chain = NULL;
                   ^

Unless I'm mistaken, you need to run do_cleanups on every return from
the function.

Afterwards, I ran a 32-bit compilation, which (after adding
--disable-largefile to avoid

In file included from /usr/include/sys/procfs.h:28:0,
                 from /vol/src/gnu/gdb/gdb/local/gdb/i386-sol2-nat.c:23:
/usr/include/sys/old_procfs.h:39:2: error: #error "Cannot use procfs in the large file compilation environment"
 #error "Cannot use procfs in the large file compilation environment"
  ^

and two more instances) revealed

/vol/src/gnu/gdb/gdb/local/gdb/top.c: In function 'void gdb_safe_append_history()':
/vol/src/gnu/gdb/gdb/local/gdb/top.c:1170:59: error: format '%d' expects argument of type 'int', but argument 3 has type 'pid_t {aka long int}' [-Werror=format=]
     = xstrprintf ("%s-gdb%d~", history_filename, getpid ());
                                                           ^

Fixed by casting pid_t to long and printing it as such.

Author: Maciej W. Rozycki <macro@imgtec.com>
Branch: gdb-7.12-branch
Commit: 1ce1f6debf17be7a5121efa0684f0ec1449f8fc4

mips-tdep: Make FCRs always 32-bit

Fix a regression from commit f8b73d13b7ca ("Target-described register
support for MIPS"),
<https://sourceware.org/ml/gdb-patches/2007-05/msg00340.html>,
<https://sourceware.org/ml/gdb-patches/2007-06/msg00256.html>, which
caused Floating Point Control Registers (FCRs) to be shown as 64-bit
with 64-bit targets.

This came from the legacy register format where all raw registers
matched the width of the architecture regardless of their actual size.
The correct size was then set in `mips_register_type' for cooked
registers presented to the user, which in the case of FCRs meant the
cooked size was always forced to 32 bits, reflecting their actual
hardware size, even though the raw format carried them in 64-bit
quantities on 64-bit targets.  The upper 32 bits carried in the raw FCR
format have always been don't-cares, not actually retrieved from
hardware and never written back.

With the introduction of XML register descriptions the layout of
previously defined raw registers has been preserved, so as to keep
existing register handling code unchanged and make it easier for GDB and
`gdbserver' to interact with each other whether neither, either or both
parties talking over RSP support XML register descriptions.  For the
XML-described case however `mips_register_type' is not used in raw to
cooked register conversion, so any special cases coded there are not
taken into account.

Instead a new function, `mips_pseudo_register_type', has been introduced
to handle size conversion, however lacking the special case for FCRs for
the Linux and the now defunct IRIX target.  The correct size has been
maintained for embedded targets however, due to the bundling of FCRs
with the embedded registers under the `rawnum >= MIPS_EMBED_FP0_REGNUM +
32' condition.

Add the missing case to `mips_pseudo_register_type' then, referring to
the FCR indices explicitly, and observing that between
`MIPS_EMBED_FP0_REGNUM + 32' and `MIPS_FIRST_EMBED_REGNUM' there is an
unused register slot whose contents are ignored so with the removal of
embedded FCRs from under that condition we don't have to care about it
and we can refer to the embedded registers starting from
MIPS_FIRST_EMBED_REGNUM instead.

Add a test case too so that we have means to check automatically that
the correct user-visible size of FCRs is maintained.

Commit a038fa3e14a4 stack: check frame_unwind_caller_id adds a frame_id check to
frame_info and treats a missing frame_id as NOT_AVAILABLE_ERROR.  This causes a

Fix PR11094: JIT breakpoint is not properly recreated on reruns

Even though this was supposedly in the gdb 7.2 timeframe, the testcase
in PR11094 crashes current GDB with a segfault:

  Program received signal SIGSEGV, Segmentation fault.

  at src/gdb/breakpoint.c:7026
  [...]

This is GDB trying to print the location spec of the JIT event
breakpoint, but that's an internal breakpoint without one.

If I add a NULL check, then we see that the JIT breakpoint is now
pending (because its location has shlib_disabled set):

  (gdb) maint info breakpoints
  Num     Type           Disp Enb Address            What
  [...]
  -8      jit events     keep y   <PENDING>           inf 1
  [...]

But that's incorrect.  GDB should have managed to recreate the JIT
breakpoint's location for the second run.  So the problem is
elsewhere.

The problem is that if the JIT loads at the same address on the second
run, we never recreate the JIT breakpoint, because we hit this early
return:

  static int
  jit_breakpoint_re_set_internal (struct gdbarch *gdbarch,
				  struct jit_program_space_data *ps_data)
  {
    [...]
    if (ps_data->cached_code_address == addr)
      return 0;

    [...]
      delete_breakpoint (ps_data->jit_breakpoint);
    [...]
    ps_data->jit_breakpoint = create_jit_event_breakpoint (gdbarch, addr);

Fix this by deleting the breakpoint and discarding the cached code
address when the objfile where the previous JIT breakpoint was found
is deleted/unloaded in the first place.

The test that was originally added for PR11094 doesn't trip on this
because:

  #1 - It doesn't test the case of the JIT descriptor's address _not_
       changing between reruns.

  #2 - And then it doesn't do "maint info breakpoints", or really
       anything with the JIT at all.

  #3 - and even then, to trigger the problem the JIT descriptor needs
       to be in a separate library, while the current test puts it in
       the main program.

The patch extends the test to cover all combinations of these
scenarios.

	* jit.c (free_objfile_data): Delete the JIT breakpoint and clear
	the cached code address.

*** TEST RESULTS FOR COMMIT e027976f02ce8ed4cf0da79238226c03a640f2b3 ***

Author: Pedro Alves <palves@redhat.com>
Branch: gdb-7.12-branch
Commit: e027976f02ce8ed4cf0da79238226c03a640f2b3

Fix a few gdb.base/jit-simple.exp problems

I noticed that we sometimes get this:

  (gdb) print &__jit_debug_descriptor
  $1 = (struct jit_descriptor *) 0x601040 <__jit_debug_descriptor>
  (gdb) PASS: gdb.base/jit-simple.exp: blah 1
  [...]
  (gdb) run
  [...]
  Starting program: build/gdb/testsuite/outputs/gdb.base/jit-simple/jit-simple
  Unsupported JIT protocol version 4 in descriptor (expected 1)

  Breakpoint 2, main () at src/gdb/testsuite/gdb.base/jit-simple.c:36
  36        return 0;
  (gdb) print &__jit_debug_descriptor
  $2 = (struct jit_descriptor *) 0x601040 <__jit_debug_descriptor>
  (gdb) PASS: gdb.base/jit-simple.exp: blah 1

All tests PASSed, but note the "Unsupported JIT protocol version 4"
message.

Also notice that "__jit_debug_descriptor" has the same address before
and after the rerun, while the test is built in a way that should make
that address change between runs.

The test doesn't catch any of this because it doesn't compare
before/after addresses.

And then notice the "blah 1" test messages.  "blah" is clearly a WIP
message, but it should be at least "blah 2" the second time.  :-)

The reason this sometimes happens is that the test recompiles the
program and expects gdb to reload it automaticallyt on "run".  However,
if the original program and the new recompilation happen to be in the
same second, then gdb does not realize that the binary needs to be
reloaded.  (This is an old problem out of scope of this series.)  If
that happens, then GDB ends up using the wrong symbols for the program
that it spawns, reads the JIT descriptor out of the wrong address,
finds garbage, and prints that "unsupported version" notice.

Fix that in the same way gdb.base/reread.exp handles it -- by sleeping
one second before recompiling.

gdb/testsuite/ChangeLog:
2016-10-06  Pedro Alves  <palves@redhat.com>

	* gdb.base/jit-simple.exp (top level) Delete get_compiler_info
	call.
	(jit_run): Delete.
	(jit_test_reread): Use with_test_prefix.  Reload the main binary
	explicitly.  Compare the before/after addresses of the JIT
	descriptor.

It was reported for qemu-system-x86_64 but it happens for any multithreaded

https://sourceware.org/ml/gdb-patches/2016-05/msg00450.html

jit_breakpoint_re_set() is specific by trying to insert a breakpoint into the
main executable, not into a shared library.  During attachment GDB thinks it
needs to use 'breakpoint always-inserted' from
breakpoints_should_be_inserted_now() as a newly attached thread is
'thread_info->executing' due to 'lwp_info->must_set_ptrace_flags' enabled and
the task not yet stopped.  This did not happen before the 'bad commit' above
which adds tracking of such thread.

GDB then fails to insert the breakpoints to invalid address as PIE executable
gets properly relocated during later phase of attachment.  One can see in the
backtraces below:
 -> jit_breakpoint_re_set_internal()
later:
 -> svr4_exec_displacement()

One can suppress the initial breakpoint_re_set() call as there will be another
breakpoint_re_set() done from the final post_create_inferior() call in
setup_inferior().

BTW additionally 'threads_executing' cache bool is somehow stale (somewhere is
missing update_threads_executing()).  I was trying to deal with that in my
first/second attempt below but in my final third attempt (attached) I have
left it as it is.

First attempt trying not to falsely require 'breakpoint always-inserted':
  https://people.redhat.com/jkratoch/rhbz1375553-fix1.patch
Reduced first attempt:
  https://people.redhat.com/jkratoch/rhbz1375553-fix2.patch

The third attempt suppresses breakpoint insertion until PIE executable gets
relocated by svr4_exec_displacement().  Applied.

If you run an infcall from the command line, and immediately after run
some other command, GDB incorrectly processes the other command before
the infcall finishes.

The problem is that the fix for PR gdb/20418 (Problems with

add_file_handler/delete_file_handler calls out of

Keep reserved bits in CPSR on write

In patch https://sourceware.org/ml/gdb-patches/2016-04/msg00529.html
I cleared reserved bits when reading CPSR.  It makes a problem that
these bits (zero) are written back to kernel through ptrace, and it
changes the state of the processor on some recent kernel, which is
unexpected.

In this patch, I keep these reserved bits when write CPSR back to
hardware.

Commit: f9a7ee181f7500b2f87687bf0c72b4b963e06acb

new-ui command: gdb internal errors if input is already pending

I noticed that if input is already pending on the new-ui TTY, gdb
internal-errors.

E.g., create /dev/pts/2, and type anything there (even just <return>
is sufficient).

Now start GDB creating a new UI on that TTY, while at the same time,
running a synchronous execution command.  Something like:

$ gdb program -ex "new-ui console /dev/pts/2" -ex "start"

Back on /dev/pts/2, we get:

  (gdb) .../src/gdb/event-top.c:360: internal-error: double prompt
  A problem internal to GDB has been detected,
  further debugging may prove unreliable.

While the main UI was waiting for "start" to finish, gdb kepts pumping
events, including the input fd of the extra console.  The problem is
that stdin_event_handler doesn't restore the current UI back to what
it was, assuming that it's only ever called from the top level event
loop.  However, in this case, it's being called from the nested event
loop from within maybe_wait_sync_command_done.

When finally the "start" command is done, we reach the code that
prints the prompt in the main UI, just before starting the main event
loop.  Since now the current UI is pointing at the extra console (by
mistake), we find ourselves printing a double prompt on the extra
console.  This is caught by the assertion that fails, as shown above.

Since other event handlers also don't restore the UI (e.g., signal
event handlers), I think it's better if whatever is pumping events to
take care to restore the UI, if it cares.  That's what this patch
does.  New test included.

Fix lwp_suspend/unsuspend imbalance in linux_wait_1

This patch fixes imbalanced lwp_suspend/unsuspend calls caused by the
premature choosing of another event for fairness.

select_event_lwp would switch the event before a call to
unsuspend_all_lwps, thus it would be called with the wrong event.

This caused an assertion failure: unsuspend LWP xx, suspended=-1 when
testing  gdb.threads/non-stop-fair-events.exp with ARM range stepping in
GDBServer.

This patch moves the switch of event after the unsuspend/unstop calls.

No regressions, tested on ubuntu 14.04 ARMv7 and x86.
With gdbserver-native.

gdb/gdbserver/ChangeLog:

	* linux-low.c (linux_wait_1): Move event switch after unsuspend_lwps.

xtensa: Avoid designated inits, for C++ compliance

C++ does not officially support designators in initializer lists.  Thus
some compilers may issue errors when encountering them.  Modern versions
of GCC seem to allow them by default, as a GCC extension, even though
the GCC documentation explicitly states otherwise: "[...] This extension
is not implemented in GNU C++."  But some older GCC versions (like
4.4.7) did indeed emit an error instead, like this:

  .../gdb/xtensa-config.c:219: error: expected primary-expression before
			       . token

This patch removes the only such instance I've seen when building with
'--enable-targets=all'.

gdb/ChangeLog:

	* xtensa-tdep.h (XTENSA_GDBARCH_TDEP_INSTANTIATE): Replace
	designated initializer list by plain initializer list, for C++
	compliance.

Allow resetting an empty inferior-tty

This patch allows the user to set the inferior-tty to "empty", in order
to come back to the default behaviour of using the same tty as gdb is
using.

This is already supported in MI (and tested in gdb.mi/mi-basics.exp).

I added a new test, set-inferior-tty.exp, where I test only the setting
and unsetting of the parameter.  It would be nice to actually test that
the inferior output properly goes to the separate tty, but that will be
for another day.

gdb/ChangeLog:

	* infcmd.c (set_inferior_io_terminal): Set inferior terminal to
	NULL if terminal_name is an empty string.
	(_initialize_infcmd): Make the argument of "set inferior-tty"
	optional, mention it in the help doc.

	inferior-tty.

the 64-bit ABI gdb only exposes 64-bit $pc/$rip (register 16 above),
on x32, GDB exposes 32-bit $eip as well, as a pseudo-register
(register 204 above).  Thus, collecting $pc/$rip automatically always

x32: Avoid unsigned long when installing fast tracepoint jump pads

We're casting through unsigned long to write a 64-bit immediate
operand of movabs (the comment said movl, but that was incorrect).
The problem is that unsigned long is 32-bit on x32, so we were writing
fewer bytes than necessary.

Fix this by using an 8 byte memcpy like in other similar places in the
function.

Author: Pedro Alves <palves@redhat.com>
Branch: gdb-7.12-branch
Commit: e24e88f9de8e4d34c052864c42aed10778f0174a

Fix PR20494 - User input stops being echoed in CLI

This patch fixes a problem that problem triggers if you start an
inferior, e.g., with the "start" command, in a UI created with the
new-ui command, and then run a foreground execution command in the
main UI.  Once the program stops for the latter command, typing in the
main UI no longer echoes back to the user.

The problem revolves around this:

- gdb_has_a_terminal computes its result lazily, on first call.

  that is what saves gdb's initial main UI terminal state (the UI
  associated with stdin):

          our_terminal_info.ttystate = serial_get_tty_state (stdin_serial);

  This is the state that target_terminal_ours() restores.

- In this scenario, the gdb_has_a_terminal function happens to be
  first ever called from within the target_terminal_init call in
  startup_inferior:

      (top-gdb) bt
      #0  gdb_has_a_terminal () at src/gdb/inflow.c:157
      #1  0x000000000079db22 in child_terminal_init_with_pgrp () at src/gdb/inflow.c:217
       [...]
      #4  0x000000000065bacb in target_terminal_init () at src/gdb/target.c:456
      #5  0x00000000004676d2 in startup_inferior () at src/gdb/fork-child.c:531
       [...]
      #7  0x000000000046b168 in linux_nat_create_inferior () at src/gdb/linux-nat.c:1112
       [...]
      #9  0x00000000005f20c9 in start_command (args=0x0, from_tty=1) at src/gdb/infcmd.c:657

If the command to start the inferior is issued on the main UI, then
readline will have deprepped the terminal when we reach the above, and
the problem doesn't appear.

If however the command is issued on a non-main UI, then when we reach
that gdb_has_a_terminal call, the main UI's terminal state is still
set to whatever readline has sets it to in rl_prep_terminal, which
happens to have echo disabled.  Later, when the following synchronous
execution command finishes, we'll call target_terminal_ours to restore
gdb's the main UI's terminal settings, and that restores the terminal
state with echo disabled...

Conceptually, the fix is to move the gdb_has_a_terminal call earlier,
to someplace during GDB initialization, before readline/ncurses have
had a chance to change terminal settings.  Turns out that
"set_initial_gdb_ttystate" is exactly such a place.

I say conceptually, because the fix actually inlines the
gdb_has_a_terminal part that saves the terminal state in
set_initial_gdb_ttystate and then simplifies gdb_has_a_terminal, since
there's no point in making gdb_has_a_terminal do lazy computation.

Fix PR gdb/20505 - Make vDSO detection work with core files

Loading a core dump that was either generated on a system running
pristine glibc master, or on a Fedora/RHEL system with LD_DEBUG=unused
set in the environment, solib-svr4.c:svr4_current_sos fails to filter
out the vDSO, resulting in:

  (gdb) core-file corefile.core^M

  warning: Could not load shared library symbols for linux-vdso.so.1.^M
  Do you need "set solib-search-path" or "set sysroot"?^M
  Core was generated by `build-gdb/gdb/testsuite/outputs/gdb.base/corefile/'.^M
  ...

The problem is that gdbarch_vsyscall_range does not support core
inferiors at all.

When live debugging, we're finding the vDSO's start address with
auxv/AT_SYSINFO_EHDR, and then we find the vDSO's size by look for the
corresponding mapping, by parsing /proc/PID/maps.  When debugging a
core dump, we can also determine the starting address from
auxv/AT_SYSINFO_EHDR.  However, we obviously can't read the core
mappings out of the host's /proc.  But we can instead look for a
corresponding load segment in the core's bfd.

[AArch64] Match instruction "STP with base register" in prologue

Nowadays, we only match pre-indexed STP in prologue.  Due to the change
in gcc, https://gcc.gnu.org/ml/gcc-patches/2016-07/msg01933.html, it
may generate "STP with base register" in prologue, which GDB doesn't
handle.  That is to say, previously GCC generates prologue like this,

 sub sp, sp, #490
 stp x29, x30, [sp, #-96]!
 mov x29, sp

with the gcc patch above, GCC generates prologue like like this,

 sub sp, sp, #4f0
 stp x29, x30, [sp]
 mov x29, sp

This patch is to teach GDB to recognize this instruction in prologue
analysis.

Commit: 2e9ffae9c70279ba7b226b9bf5f2f9b20968375c

[GDB] Fix builds broken by proc-service changes.

GLIBC BZ#20311 introduced a change to install proc_service.h so that gdb
didn't have to use the version it embeds in gdb_proc_service.h. The
embedded version is guarded by HAVE_PROC_SERVICE_H and
gdb_proc_service.h has a number other of includes and definitions, all
of which are uncondional except for an include for gregset.h. This is
only included if HAVE_PROC_SERIVCE_H is not defined.

This causes a build failure when cross compiling gdb with the latest
glibc because type definitions in gregset are used independently of
HAVE_PROC_SERIVCE_H. In particular, they are used in gdb_proc_service.h
when PRFPREGSET_T_BROKEN is set.

The error messages on the failure are
----
binutils-gdb/gdb/gdb_proc_service.h:173:9: error: gdb_fpregset_t does
not name a type; did you mean elf_fpregset_t?

This patch moves the include for gregset.h to before the code guarded by
HAVE_PROC_SERIVCE_H, so that it is always included. This is enough to
fix the build.

the code in question is:

>             && (*inp)[9] == ',')
>           (*inp) += 9;
>         ++(*inp);

The error is caused by the access to (*inp)[9] if 9 is out of its bounds.
However [1] looks odd to me, because if strncmp returns true (non-zero),
the following check "(*inp)[9] == ','" makes no sense any more.  I
suspect it was a typo in the code we meant to "strncmp () == 0".  Another
problem in the code above is that if *inp is "operator,", we first
increment *inp by 9, and then increment it by one again, which is wrong
to me.  We should only increment *inp by 8 to skip "operator", and go
back to the loop header to decide where we stop.

gdb:

	* location.c (explicit_location_lex_one): Compare the return
	value of strncmp with zero.  Don't check (*inp)[9].  Increment
	*inp by 8.

sim: bfin: split out common mach/model defines into arch.h [PR sim/20438]

The current machs.h mixes common enums with Blackfin-specific defines.
This causes us troubles with header inclusion order such that we can't
drop the old SIM_CPU typedef (which is duplicated in common code).  By
splitting the two up, we can unwind this dependency chain, and drop the
old typedef.  It also fixes building with older gcc versions.

Commit: 4dfacf706adacbefbc38d7ba59212566f77bd051

Fix PR gdb/19187 (process record over a fork causes internal error)

Right after a fork is detected, we detach breakpoints from the child
(detach_breakpoints), which calls into target_remove_breakpoint with
inferior_ptid pointing at the child process, but leaves the breakpoint
marked inserted (in the parent).

The problem is that record-full.c always deletes all knowledge of the
breakpoint.  Then when we later really delete the breakpoint from the
parent, we fail the assertion, since the breakpoint is unexpectedly
not found in the record-full.c breakpoint table.

The fix is simply to not forget about the breakpoint if we're
detaching it from a fork child.

	PR gdb/19187

Commit: b24bdfa398beba87b48fffeb3b1f9bcfe7bf924d

Fix PR gdb/20418 - Problems with synchronous commands and new-ui

When executing commands on a secondary UI running the MI interpreter,
some commands that should be synchronous are not.  MI incorrectly
continues processing input right after the synchronous command is
sent, before the target stops.

The problem happens when we emit MI async events (=library-loaded,
etc.), and we go about restoring the previous terminal state, we end
up calling target_terminal_ours, which incorrectly always installs the
current UI's input_fd in the event loop...  That is, code like this:

   old_chain = make_cleanup_restore_target_terminal ();
   target_terminal_ours_for_output ();

   fprintf_unfiltered (mi->event_channel, "library-loaded");

...

   do_cleanups (old_chain);

The fix is to move the add_file_handler/delete_file_handler calls out
of target_terminal_$foo, making these completely no-ops unless called
with the main UI as current UI.

Fix PR mi/20431 - Missing MI prompts after sync execution MI command (-exec-continue, etc.) errors

gdb 7.11 introduced an MI regression: a failing MI sync execution
command misses printing the MI prompt, and then all subsequent command
miss it too:

 $ gdb-7.11.1 -i=mi
 [...]
 p 1
 &"p 1\n"
 ~"$1 = 1"
 ~"\n"
 ^done
 (gdb)                                        <<< prompted ok
 -exec-continue
 ^error,msg="The program is not being run."   <<< missing prompt after this
 print 1
 &"print 1\n"
 ~"$2 = 1"
 ~"\n"
 ^done                                        <<< missing prompt after this


gdb 7.10.1 behaved correctly, even with "set mi-async on":

 -exec-continue
 ^error,msg="The program is not being run."
 (gdb)                                        <<< prompted ok

etc.

Bisecting points at:

  commit 0b333c5e7d6c
  Author: Pedro Alves <palves@redhat.com>
  Date:   Wed Sep 9 18:23:23 2015 +0100

      Merge async and sync code paths some more
  [...]

The problem is that when an exception is thrown, we leave the prompt
state set to PROMPT_BLOCKED, and then mi_execute_command_input_handler
doesn't print the prompt.  It used to work because before that patch,
we happened to skip disabling stdin if the current target didn't do
async (which it never does before execution).

I was surprised to find that this bug isn't caught by the testsuite,
so I made a thorough test that tests all combinations of pairs of:

 - a failing synchronous execution command
 - a failing non-execution command
 - a non-failing command

*** TEST RESULTS FOR COMMIT 26fdfd0a18cf9032183a498a6c68b16f5042b1a4 ***

Author: Pedro Alves <palves@redhat.com>
Branch: gdb-7.12-branch
Commit: 26fdfd0a18cf9032183a498a6c68b16f5042b1a4

Fix PR remote/20398: File-IO write always outputs "Quit"

Commit bb7c96deb1a1 ("gdb/remote-fileio.c: Eliminate custom SIGINT
signal handler") regressed the File-IO support.

Failed output:

  (gdb) target remote :8888
  Remote debugging using :8888
  0x00008098 in _start ()
  (gdb) c
  Continuing.
  Quit
  Quit
  Quit

  [Inferior 1 (Remote target) exited normally]

Expected output:

  (gdb) target remote :8888
  Remote debugging using :8888
  0x00008098 in _start ()
  (gdb) c
  Continuing.
  i: 0

  [Inferior 1 (Remote target) exited normally]

The problem that the new File-IO quit handler forgets to check the
quit flag before calling throwing a quit.

gdb/ChangeLog:
2016-08-05  Pedro Alves  <palves@redhat.com>

	PR remote/20398
	* remote-fileio.c (remote_fileio_quit_handler): Check the quit
	flag before calling quit.

gdb/configure --help: suggest --disable-build-with-cxx instead of --enable...

We build by default with a C++ compiler, but "configure --help" still
says "--enable-build-with-cxx", which hints that it is by default
disabled.  Update the --help text.

Author: Yao Qi <yao.qi@linaro.org>
Branch: gdb-7.12-branch
Commit: f2b5d52a1d4484e55cd36de24554b51c2133386b

Determine target description for native aarch64

I find the following test fail when I test native aarch64 gdb with
arm program,

(gdb) PASS: gdb.base/attach-pie-noexec.exp: attach
set architecture arm^M
warning: Selected architecture arm is not compatible with reported target architecture aarch64^M
Architecture `arm' not recognized.^M
The target architecture is set automatically (currently aarch64)^M
(gdb) FAIL: gdb.base/attach-pie-noexec.exp: set architecture arm

GDB thinks the target is aarch64, but it isn't.  Nowadays, we are
using some entries AT_PHENT and AT_HWCAP in auxv to determine whether
the process is a 32-bit arm one or 64-bit aarch64 one, and get the
right gdbarch.  However, in the process of parsing auxv (in
inf_ptrace_auxv_parse), the size of int and data pointer of
target_gdbarch is used.  If debug program exists (in most of cases),
target_gdbarch is already set according to the debug program, which
is arm in my case.  Then, GDB can parse auxv successfully.  However,
in gdb.base/attach-pie-noexec.exp, the debug program is removed,
target_gdbarch is aarch64 when GDB parse auxv, so GDB can't parse
it successfully.

Instead of using auxv, we check the return value of ptrace NT_ARM_VFP.
If the program is an arm process, NT_ARM_VFP is OK, otherwise, error
is returned.

Additionally, we only return tdesc_arm_with_neon for arm process,
because neon is mandatory on ARMv8.

gdb:

2016-08-04  Yao Qi  <yao.qi@linaro.org>

	* aarch64-linux-nat.c (tdesc_arm_with_vfpv3): Remove the
	declaration.
	(aarch64_linux_read_description): Remove code on getting
	auxv and select target description on it.  Select target
	description by the result of NT_ARM_VFP ptrace request.

PR python/18565 - make Frame.function work for inline frames

PR python/18565 notes that calling frame filters don't work properly for
inlined functions.  This happens because Frame.function on an inline
frame will yield the wrong result.  This patch changes this code to use
find_frame_funname instead, which handles inline frames properly.

Built and regtested on x86-64 Fedora 24.

2016-08-03  Tom Tromey  <tom@tromey.com>

	PR python/18565:
	* python/py-frame.c (frapy_function): Use find_frame_funname.

2016-08-03  Tom Tromey  <tom@tromey.com>

Avoid potential memory leak in find_frame_funname

The PR 18565 thread pointed out that, if cp_remove_params can throw
(we aren't quite sure), then find_frame_funname could leak some
memory.  This patch avoids any potential issue by rearranging some
code in find_frame_funname.
