testsuite: Fix gdb.arch/powerpc-prologue.c compilation

gcc-6.2.1

gdb compile failed, gdb/testsuite/gdb.arch/powerpc-prologue.c: In function 'main':
gdb/testsuite/gdb.arch/powerpc-prologue.c:32:3: warning: implicit declaration of function 'optimized_1' [-Wimplicit-function-declaration]
   optimized_1 ();
   ^~~~~~~~~~~

gdb/testsuite/ChangeLog
2016-10-11  Jan Kratochvil  <jan.kratochvil@redhat.com>

* gdb.arch/powerpc-prologue.c (optimized_1): New declaration.

testsuite: Use standard_output_file

gdb/testsuite/ChangeLog
2016-10-11  Jan Kratochvil  <jan.kratochvil@redhat.com>

* gdb.arch/powerpc-prologue.exp: Use standard_output_file.
* gdb.arch/ppc64-symtab-cordic.exp: Likewise.
* gdb.arch/vsx-regs.exp: Likewise.

Enhance objdump so that it will use .got, .plt and .plt.got section symbols when disassembling, and it will use dynamic relocs to interpret entries in the PLT and GOT.

binutils * objdump.c (is_significant_symbol_name): New function.
(remove_useless_symbols): Do not remove significanr symbols.
(find_symbol_for_address): If an exact match for the specified
address has not been found, try scanning the dynamic relocs to see
if one of these matches the address.  If so, use the symbol
associated with the reloc.
(objdump_print_addr_with_symbol): Do not print offsets to symbols
with no value.
(disassemble_section): Only use dynamic relocs if the user
requested this.
(disassemble_data): Always load dynamic relocs if they are
available.

Always descend into output section statements in lang_do_assignments

See https://sourceware.org/ml/binutils/2016-07/msg00091.html
This patch stop --gc-sections elf_gc_sweep_symbol localizing symbols
that ought to remain global.

The difficulty with always descending into output section statements
is that symbols defined by the script in such statements don't have
a bfd section when lang_do_assignments runs early in the link process.
There are two approaches to curing this problem.  Either we can
create the bfd section early, or we can use a special section.  This
patch takes the latter approach and uses bfd_und_section.  (Creating
bfd sections early results in changed output section order, and thus
lots of testsuite failures.  You can't create all output sections
early to ensure proper ordering as KEEP then stops empty sections
from being stripped.)

The wrinkle with this approach is that some code that runs at
gc-sections time needs to be made aware of the odd defined symbols
using bfd_und_section.

MIPS64: Adjust cfi* testcases.

The CFI* testcases fail on MIPS64 because the augmentation string does
not match the regexp. This is because MIPS64 doesn't use the default of
4 for DWARF2_FDE_RELOC_SIZE which ends up as "b" in the augmentation
string. MIPS64 uses the address size which is 8 resulting in "c".

Adding c to the regexp fixes a couple of them. Others also need
adjustments in the FDE header lines due to different
sizes/offsets.

development or use for years now, and was recently removed from GCC.
This patch changes gdb to follow; in the unlikely event that there are

Or, they can debug in C++ mode.

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.

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.

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.

Fix incorrect formatting of a ChangeLog entry

fixes that.

Allow DW_OP_GNU_uninit in dwarf_expr_require_composition

In DWARF expression handling, some operators are required to be either
at the end of an expression or followed by a composition operator.  So
far only the operators DW_OP_reg0-31 were allowed to be followed by
DW_OP_GNU_uninit instead, and particularly DW_OP_regx was not, which is
obviously inconsistent.

This patch allows DW_OP_GNU_uninit after all operators requiring a
composition, to simplify the code and make it more consistent.  This
policy may be more permissive than necessary, but in the worst case just
leads to a DWARF location description resulting in an uninitialized
value instead of an error message.

Simplify i386, amd64 and x32 expedite registers

Nowadays, there are a lot of duplication about
i386/{i386, amd64, x32}*-expedite in features/Makefile.  However,
in features/Makefile, we have

 echo "expedite:$(if $($*-expedite),$($*-expedite),$($(firstword $(subst -, ,$(notdir $*)))-expedite))" \
  >> $(outdir)/$*.tmp

which means for a given bar/foo-baz.xml, we'll look for either
bar/foo-baz-expedite or foo-expedite.  In x86 expedite registers, we
use the former now, but it will be much simpler if we use the latter.

Fold arithmetic integer expressions

Commit b751e639 regressed arm linux kernel builds, that have an
ASSERT (((__hyp_idmap_text_end - (__hyp_idmap_text_start
                  & ~ (((0x1 << 0xc) - 0x1))))
         <= (0x1 << 0xc)), HYP init code too big or misaligned)

Due to some insanity in ld expression evaluation, the integer values
0x1 and 0xc above are treated as absolute addresses (ie. they have an
associated section, *ABS*, see exp_fold_tree_1 case etree_value) while
the expression (0x1 << 0xc) has a plain number result.  The left hand
side of the inequality happens to evaluate to a "negative" .text
section relative value.  Comparing a section relative value against an
absolute value works since the section relative value is first
converted to absolute.  Comparing a section relative value against a
number just compares the offsets, which fails since the "negative"
offset is really a very large positive number.

This patch works around the problem by folding integer expressions, so
the assert again becomes
ASSERT (((__hyp_idmap_text_end - (__hyp_idmap_text_start
                  & 0xfffffffffffff000))
         <= 0x1000), HYP init code too big or misaligned)

Add test for user context selection sync

This patch adds a test to verify that events are sent properly to all
UIs when the user selection context (inferior, thread, frame) changes.

The goal of the C test file is to provide two threads that are stopped with the
same predictable backtrace (so that we can test frame switching).  The barrier
helps us know when the child threads are started.  Then, scheduler-locking is
used to bring each thread one by one to the position we expect them to be
during the test.

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

PR 20627: Use resume_stop to stop lwp

Commit 049a8570 (Use target_continue{,_no_signal} instead of target_resume)
replaces the code stopping lwp with target_continue_no_signal in

It was reported for qemu-system-x86_64 but it happens for any multithreaded
inferior with a JIT debugging hook.

136613ef0c6850427317e57be1b644080ff6decb is the first bad commit

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.

      DW_CFA_restore: r14
      DW_CFA_def_cfa_offset: 160

    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.

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
than "memory breakpoint".  Further document "kind".  Move
protocol-details link earlier.
<z1>: Document the cmd_list argument.  Fix typo.
<g>: Remove incorrect sentence.
(Stop Reply Packets): Document "OK" response to requests when in
non-stop mode.
<swbreak>: Use "software breakpoint" rather than "memory
breakpoint".
<create>: Document that "R" is ignored.
<W, X, w>: Document formatting of "AA".
(Notification Packets): Use "%Stop", not "%%Stop".

Fix seg-fault in the linker introduced by the previous delta.

* testsuite/ld-arm/arm-elf.exp: Handle new testcase.

Don't treat as separate symbols if unversioned symbol is undefined.

When we see an unversioned symbol reference in a shared library, followed
by a default definition of the symbol in another shared library, we were
treating them as separate symbols. That should only happen when both are
definitions.

* symtab.cc (Symbol_table::define_default_version): Check that
unversioned symbol is defined.

Add archives and make stamps to the .gitignore file.
