Due to some insanity in ld expression evaluation, the integer values

Antoine Tremblay [Mon, 3 Oct 2016 20:52:44 +0000 (16:52 -0400)]
Emit inferior, thread and frame selection events to all UIs

With this patch, when an inferior, thread or frame is explicitly
selected by the user, notifications will appear on all CLI and MI UIs.
When a GDB console is integrated in a front-end, this allows the
front-end to follow a selection made by the user ont he CLI, and it
informs the user about selection changes made behind the scenes by the
front-end.

This patch addresses PR gdb/20487.

In order to communicate frame changes to the front-end, this patch adds
a new field to the =thread-selected event for the selected frame.  The
idea is that since inferior/thread/frame can be seen as a composition,
it makes sense to send them together in the same event.  The vision
would be to eventually send the inferior information as well, if we find
that it's needed, although the "=thread-selected" event would be
ill-named for that job.

Front-ends need to handle this new field if they want to follow the
frame selection changes that originate from the console.  The format of
the frame attribute is the same as what is found in the *stopped events.

Here's a detailed example for each command and the events they generate:

thread
------

1. CLI command:

     thread 1.3

   MI event:

     =thread-selected,id="3",frame={...}

2. MI command:

     -thread-select 3

   CLI event:

     [Switching to thread 1.3 ...]

3. MI command (CLI-in-MI):

     thread 1.3

   MI event/reply:

     &"thread 1.3\n"
     ~"#0  child_sub_function () ...
     =thread-selected,id="3",frame={level="0",...}
     ^done

frame
-----

1. CLI command:

     frame 1

   MI event:

     =thread-selected,id="3",frame={level="1",...}

2. MI command:

     -stack-select-frame 1

   CLI event:

     #1  0x00000000004007f0 in child_function...

3. MI command (CLI-in-MI):

     frame 1

   MI event/reply:

     &"frame 1\n"
     ~"#1  0x00000000004007f9 in ..."
     =thread-selected,id="3",frame={level="1"...}
     ^done

inferior
--------

Inferior selection events only go from the console to MI, since there's
no way to select the inferior in pure MI.

1. CLI command:

     inferior 2

   MI event:

     =thread-selected,id="3"

Note that if the user selects an inferior that is not started or exited,
the MI doesn't receive a notification.  Since there is no threads to
select, the =thread-selected event does not apply...

2. MI command (CLI-in-MI):

     inferior 2

   MI event/reply:

     &"inferior 2\n"
     ~"[Switching to inferior 2 ...]"
     =thread-selected,id="4",frame={level="0"...}
     ^done

Internal implementation detail: this patch makes it possible to suppress
notifications caused by a CLI command, like what is done in mi-interp.c.
This means that it's now possible to use the
add_com_suppress_notification function to register a command with some
event suppressed.  It is used to implement the select-frame command in
this patch.

The function command_notifies_uscc_observer was added to extract
the rather complicated logical expression from the if statement.  It is
also now clearer what that logic does: if the command used by the user
already notifies the user_selected_context_changed observer, there is
not need to notify it again.  It therefore protects again emitting the
event twice.

No regressions, tested on ubuntu 14.04 x86 with target boards unix and
native-extended-gdbserver.

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':

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.

    This is triggered by this check in display_debug_frames (dwarf.c):

case DW_CFA_restore:
  if (opa >= (unsigned int) cie->ncols
      || opa >= (unsigned int) fc->ncols)
    reg_prefix = bad_reg;

cie->ncols is number of registers referenced in the CIE which is 15 due
to r14 being given as return address column.  So for the CFA_restore of
r15 a "bad register" is being printed while the same rule on r14 is ok.

The reason for this check is to prevent wild memory accesses when
reading input with corrupted register values while accessing the
col_type/col_offset arrays. However in that case r15 is a perfectly
valid register. It just happens not to be mentioned in the CIE.  Hence
restoring the CIE rule for r15 should end up with the default rule which
is DW_CFA_undefined.

This probably wasn't observed on other platforms because they either do
not use CFA_restore (x86-64) or do not issue CFA_restore on registers
with a higher number than the return address column.

Tom Tromey [Tue, 13 Sep 2016 22:50:34 +0000 (16:50 -0600)]
Small improvements to the remote protocol manual

I was reading the gdb RSP manual recently and I found a number of
small problems in the documentation.  This patch attempts to improve
these areas.  Specfically:

* The term "memory breakpoint" is used only in this section of the
  manual, and there inconsistently.  I found this term confusing --
  initially I thought it might be a watchpoint.  This patch changes it
  to use the term "software breakpoint", which is used in the rest of
  the manual.

* The z0 packet didn't document how "kind" was written.  And, it had a
  stray link to the architecture-specific protocol details node.  This
  patch moves this link to a better spot.

* The z1 patch didn't document that it accepts cmd_list.

* I couldn't find any text saying what response is given to a command
  like vCont in non-stop mode.  The answer is that OK is sent, and
  then a stop reply is sent as a notification.  This patch adds a note
  about this.

* The "create" stop reply did not document that the "R" argument is
  ignored.

* The "W", "X", and "w" packets did not document how the "AA" part is
  formatted.

* The %Stop notification example said "%%Stop", but I think this is
  incorrect.

* gdb.texinfo (Packets) <z0>: Use "software breakpoint" rather

8 years agogdb: Replace operator new / operator new[]
Pedro Alves [Fri, 23 Sep 2016 15:42:24 +0000 (16:42 +0100)]
gdb: Replace operator new / operator new[]

If xmalloc fails allocating memory, usually because something tried a
huge allocation, like xmalloc(-1) or some such, GDB asks the user what
to do:

  .../src/gdb/utils.c:1079: internal-error: virtual memory exhausted.
  A problem internal to GDB has been detected,
  further debugging may prove unreliable.
  Quit this debugging session? (y or n)

If the user says "n", that throws a QUIT exception, which is caught by
one of the multiple CATCH(RETURN_MASK_ALL) blocks somewhere up the
stack.

The default implementations of operator new / operator new[] call
malloc directly, and on memory allocation failure throw
std::bad_alloc.  Currently, if that happens, since nothing catches it,
the exception escapes out of main, and GDB aborts from unhandled
exception.

This patch replaces the default operator new variants with versions
that, just like xmalloc:

 #1 - Raise an internal-error on memory allocation failure.

 #2 - Throw a QUIT gdb_exception, so that the exact same CATCH blocks
      continue handling memory allocation problems.

A minor complication of #2 is that operator new can _only_ throw
std::bad_alloc, or something that extends it:

  void* operator new (std::size_t size) throw (std::bad_alloc);

That means that if we let a gdb QUIT exception escape from within
operator new, the C++ runtime aborts due to unexpected exception
thrown.

So to bridge the gap, this patch adds a new gdb_quit_bad_alloc
exception type that inherits both std::bad_alloc and gdb_exception,
and throws _that_.

If we decide that we should be catching memory allocation errors in
fewer places than all the places we currently catch them (everywhere
we use RETURN_MASK_ALL currently), then we could change operator new
to throw plain std::bad_alloc then.  But I'm considering such a change
as separate matter from this one -- it'd make sense to do the same to
xmalloc at the same time, for instance.

Meanwhile, this allows using new/new[] instead of xmalloc/XNEW/etc.
without losing the "virtual memory exhausted" internal-error
safeguard.

Tested on x86_64 Fedora 23.

The immediate problem is that quit_force resets the terminal before
evaluating the expression.  However, it seemed to me that it doesn't

SVE defines new names for existing NZCV conditions, to reflect the

names.

The patch also adds comments to the disassembly output to show the
alternative names of a condition code.  For example:

cinv x0, x1, cc

becomes:

      cinv x0, x1, cc  // cc = lo, ul, last

and:

b.cc f0 <...>

becomes:

      b.cc f0 <...>  // b.lo, b.ul, b.last

Doing this for the SVE names follows the practice recommended by the
SVE specification and is definitely useful when reading SVE code.

[AArch64][SVE 28/32] Add SVE FP immediate operands

This patch adds support for the new SVE floating-point immediate
operands.  One operand uses the same 8-bit encoding as base AArch64,
but in a different position.  The others use a single bit to select
between two values.

One of the single-bit operands is a choice between 0 and 1, where 0
is not a valid 8-bit encoding.  I think the cleanest way of handling
these single-bit immediates is therefore to use the IEEE float encoding
itself as the immediate value and select between the two possible values
when encoding and decoding.

As described in the covering note for the patch that added F_STRICT,
we get better error messages by accepting unsuffixed vector registers
and leaving the qualifier matching code to report an error.  This means
that we carry on parsing the other operands, and so can try to parse FP
immediates for invalid instructions like:

fcpy z0, #2.5

In this case there is no suffix to tell us whether the immediate should
be treated as single or double precision.  Again, we get better error
messages by picking one (arbitrary) immediate size and reporting an error
