Sanitize input_interrupt output

Hi,

This patch is a follow-up of the following discussions:

  <https://sourceware.org/ml/gdb-patches/2014-12/msg00421.html>
  <https://gcc.gnu.org/ml/gcc-patches/2014-12/msg01293.html>

input_interrupt is currently emiting non-printable characters, which
is confusing the dg-extract-results.sh script.  This is obviously not
a good thing, and, by following Pedro's advices here:

  <https://gcc.gnu.org/ml/gcc-patches/2014-12/msg01320.html>

I adapted the function to print "client connection closed" when it
receives a NUL character, or use the "isprint" function to decide how
to print the received char.  I tested it by running the testcases that
were printing the non-printable chars before:

  gdb.base/gdb-sigterm.exp
  gdb.threads/non-ldr-exc-1.exp
  gdb.threads/non-ldr-exc-2.exp
  gdb.threads/non-ldr-exc-3.exp
  gdb.threads/non-ldr-exc-4.exp
  gdb.threads/thread-execl.exp

and confirming that they print the right message.  I tried a bit to
come up with a testcase for this, but failed, and since I did not want
to spend too much time on it, I'm sending the patch anyway.

Comments are welcome, as usual.

9 years agoAVR/ld: Propagate link-relax elf header flag correctly.
Andrew Burgess [Sat, 22 Nov 2014 23:25:17 +0000 (23:25 +0000)] 
AVR/ld: Propagate link-relax elf header flag correctly.

The AVR target has an elf header flag to indicate if an object was
assembler ready for linker relaxation.  If a partial link is performed
then it is important that the link-relax flag in the output object is
set correctly, otherwise, during the final link, we might try to perform
linker relaxation on code that was not assembled suitably.

As the link-relax elf header covers the entire object file we must be
conservative when setting the flag in the output object, so, for a
partial link, any input object that does not have the link-relax flag
set will cause the output object to also not have the link-relax flag
set.

This conservative approach could be softened in future, we only need to
disable the link relax flag if an input file is not marked link-relax
ready, and the input file contains a relaxable section.  However, I've
left this optimisation for a later day.

For the final link I've overloaded the use of the link-relax elf header
flag, in a final executable, the flag now indicates if the executable
was built with linker relaxation on or not.

Mihail-Marian Nistor [Sat, 20 Dec 2014 16:04:44 +0000 (11:04 -0500)] 
gdb/17394: cannot put breakpoint only in selected ASM file.

This patch fixes a problem when trying to insert a breakpoint on
a specific symbol defined in a specific file, eg:

    break foo.c:func

This currently works for files in C/C++/Ada, etc, but doesn't always
work for Asm files. Analysis of the problem showed that this related
to a limitation in gas, which does not generate debug info for functions/
symbols.  Thus, we have a symtab for the file ("info sources" shows
the file), but it contains no symbols.

When find_linespec_symbols is called in linespec_parse_basic, it calls
find_function_symbols, which uses add_matching_symbols_to_info to
collect all matching symbols.

That function does [pardon any mangled formatting]:

  for (ix = 0; VEC_iterate (symtab_ptr, info->file_symtabs, ix, elt); ++ix)
    {
      if (elt == NULL)
        {
          iterate_over_all_matching_symtabs (info->state, name, VAR_DOMAIN,
                                             collect_symbols, info,
                                             pspace, 1);
          search_minsyms_for_name (info, name, pspace);
        }
      else if (pspace == NULL || pspace == SYMTAB_PSPACE (elt))
        {
          /* Program spaces that are executing startup should have
             been filtered out earlier.  */
          gdb_assert (!SYMTAB_PSPACE (elt)->executing_startup);
          set_current_program_space (SYMTAB_PSPACE (elt));
          iterate_over_file_blocks (elt, name, VAR_DOMAIN,
                                    collect_symbols, info);
        }
    }

This iterates over the symtabs. In the failing use case, ELT is
non-NULL (points to the symtab for the .s file), so it calls
iterate_over_file_blocks. Herein is where the problem exists: it is
assumed that if NAME exists, it must exist in the given symtab -- a
reasonable assumption for "normal" (non-asm) cases. It never searches
minimal symbols (or in the global default symtab).

This patch fixes the problem by doing so. It is important to note that
iterating over minsyms is fairly expensive, so this patch only adds
that extra search if the language is language_asm and
iterate_over_file_blocks returns no symbols.

9 years agoMIPS: Provide FPU info and decode FCSR in `info float'
Yao Qi [Thu, 18 Dec 2014 12:47:28 +0000 (20:47 +0800)] 
MIPS: Provide FPU info and decode FCSR in `info float'

This patch is the V2.  V1 can be found in
https://sourceware.org/ml/gdb-patches/2012-05/msg00938.html
V2 is to address Joel's comment
<https://sourceware.org/ml/gdb-patches/2012-06/msg00289.html> about
keeping dumping floating point registers.  Additionally, command
'info float' prints bits on nan2008 and abs2008.

------------------------------------------------------------------

 The change below provides a MIPS-specific handler for the:

(gdb) info float

command.  It provides information about the FPU type available (if any),
the FPU register width, and decodes the CP1 Floating Point Control and
Status Register (FCSR):

(gdb) print /x $fsr
$1 = 0xff83ffff
(gdb) info float
fpu type: double-precision
reg size: 32 bits
cond    : 0 1 2 3 4 5 6 7
cause   : inexact uflow oflow div0 inval unimp
mask    : inexact uflow oflow div0 inval
flags   : inexact uflow oflow div0 inval
rounding: -inf
flush   : zero

 One point to note about CP1.FCSR are the non-standard Flush-to-Nearest
and Flush-Override bits.  They are not a part of the MIPS architecture and
take two positions reserved for an implementation-dependent use in the
architecture.  They are present in all the FPU implementations made by
MIPS Technologies since the spin-off from SGI.

 I haven't been able to track down a single other MIPS FPU implementation
that would make any use of these bits and they are required to be
hardwired to zero by the architecture specification if unimplemented.
Therefore I think it makes sense to report them in the current way.

 GDB has no guaranteed access to the CP0 Processor Identification (PRId)
register to validate this feature properly and the ID information stored
in the CP1 Floating Point Implementation Register (FIR) is from my
experience not reliable enough (there's no Company ID available there for
once unlike in CP0.PRId and Processor ID is not guaranteed to be unique).

 As a side note we should probably dump CP1.FIR information as well, as
there's useful stuff indicating some FPU features there.  That's material
for another change however.

9 years ago[Linux] Ask kernel to kill inferior when GDB terminates
Joel Brobecker [Tue, 11 Nov 2014 06:07:21 +0000 (10:07 +0400)] 
[Linux] Ask kernel to kill inferior when GDB terminates

This patch enhances GDB on GNU/Linux systems in the situation where
we are debugging an inferior that was created from GDB (as opposed
to attached to), by asking the kernel to kill the inferior if GDB
terminates without doing it itself.

This would typically happen when GDB encounters a problem and
crashes, or when it gets killed by an external process. This can
be observed by starting a program under GDB, and then killing
GDB with signal 9. After GDB is killed, the inferior still remains.

This patch also fixes GDBserver similarly.

This fix is conditional on the kernel supporting the PTRACE_O_EXITKILL
feature.  On older kernels, the behavior remains unchanged.

gdb/ChangeLog:

        * nat/linux-ptrace.h (PTRACE_O_EXITKILL): Define if not
        already defined.
        (linux_enable_event_reporting): Add parameter "attached".
        * nat/linux-ptrace.c (linux_test_for_exitkill): New forward
        declaration.  New function.
        (linux_check_ptrace_features): Add linux_test_for_exitkill call.
        (linux_enable_event_reporting): Add new parameter "attached".
        Do not call ptrace with the PTRACE_O_EXITKILL if ATTACHED is
        nonzero.
        * linux-nat.c (linux_init_ptrace): Add parameter "attached".
        Use it.  Update function description.
        (linux_child_post_attach, linux_child_post_startup_inferior):
        Update call to linux_enable_event_reporting.

gdb/gdbserver/ChangeLog:

        * linux-low.c (linux_low_filter_event): Update call to
        linux_enable_event_reporting following the addition of
        a new parameter to that function.

Tested on x86_64-linux, native and native-gdbserver.

I also verified by hand that the inferior gets killed when killing
GDB in the "run" case, while the inferior remains in the "attach"
case. Same for GDBserver.
