10 years agoGDB/MI: Add new "--language LANG" command option.

GDB/MI: Add new "--language LANG" command option.

Frontend sometimes need to evaluate expressions that are
language-specific. For instance, Eclipse uses the following
expression to determine the size of an address on the target:

    -data-evaluate-expression "sizeof (void*)"

Unfortunately, if the main of the program being debugged is not C,
this may not work. For instance, if the main is in Ada, you get...

    -data-evaluate-expression "sizeof (void*)"
    ^error,msg="No definition of \"sizeof\" in current context."

... and apparently decides to stop the debugging session as a result.
The  recommendation sent was to specifically set the language to C
before trying to evaluate the expression.  Something such as:

    1. save current language
    2. set language c
    3. -data-evaluate-expression "sizeof (void*)"
    4. Restore language

This has the same disadvantages as the ones outlined in the "Context
Management" section of the GDB/MI documentation regarding setting
the current thread or the current frame, thus recommending the use of
general command-line switches such as --frame, or --thread instead.

This patch follows the same steps for the language, adding a similar
new command option: --language LANG. Example of use:

    -data-evaluate-expression --language c "sizeof (void*)"
    ^done,value="4"

10 years agocrash while re-reading symbols from objfile on ppc-aix.
Joel Brobecker [Tue, 5 Nov 2013 12:01:45 +0000 (07:01 -0500)] 
crash while re-reading symbols from objfile on ppc-aix.

This patch aims at fixing the following problem, where the user:

  . debugs its program
  . makes a modification and rebuilds it *without exiting the debugger*
  . returns to its debugging session and restarts the inferior

In that situation, the debugger notices that the underlying executable
has changed and that re-reading its symbols is needed. Shortly after
displaying a message informing the user of the situation, GDB crashes:

   (gdb) run
   [...]
   `/[...]/dest' has changed; re-reading symbols.
   zsh: 13434922 segmentation fault (core dumped)

The crash occurs while trying to allocate some memory on the bfd_bfd
obstack.  But, at some point in time, the whole obstack data gets
corrupted, nullified. So the memory allocation fails trying to call
a function at a NULL address. (side note: when debugging GDB in GDB,
top-gdb reports a SIGILL, while the shell makes it look like it was
a SIGSEGV - the discrepancy is not critical to the investigation
and therefore was not explored)

The corruption occurred because the region where the per_bfd data
got free'ed nearly after it got allocated! This is what happens,
in chronological order (see reread_symbols):

  1. GDB notices that the executable has changed, decides to
     re-read its symbols.

  2. Opens a new bfd, unrefs the old one

  3. Calls set_objfile_per_bfd (objfile);

  4. Re-initializes the objfile's obstack:
     obstack_init (&objfile->objfile_obstack);

I think that the normal behavior for set_objfile_per_bfd would
be to search for already-allocated shared per_bfd data, and
allocate new one if not found.  The critical difference between
a platform such as x86_64-linuxe where it works, and ppc-aix,
where it doesn't lies in the fact that bfd-data sharing is not
activated on ppc-aix, and as a result, the per-bfd data gets
allocated on the objfile's obstack instead of in the bfd objalloc:

      /* If the object requires gdb to do relocations, we simply fall
         back to not sharing data across users.  These cases are rare
         enough that this seems reasonable.  */
      if (abfd != NULL && !gdb_bfd_requires_relocations (abfd))
        {
          storage = bfd_zalloc (abfd, sizeof (struct objfile_per_bfd_storage));
          set_bfd_data (abfd, objfiles_bfd_data, storage);
        }
      else
        storage = OBSTACK_ZALLOC (&objfile->objfile_obstack,
                                  struct objfile_per_bfd_storage);

Allocating that per_bfd storage is of course nearly useless since
we end up free-ing right after in step (4) above. Eventually,
the memory region ends up being re-used, hence the corruption
leading to the crash.

This fix was simply to move the call to set_objfile_per_bfd after
the objfile's obstack re-initialization.

10 years agoDandling memory pointers in Ada catchpoints with GDB/MI.
Joel Brobecker [Wed, 30 Oct 2013 10:18:24 +0000 (11:18 +0100)] 
Dandling memory pointers in Ada catchpoints with GDB/MI.

When using the GDB/MI commands to insert a catchpoint on a specific
Ada exception, any re-evaluation of that catchpoint (for instance
a re-evaluation performed after a shared library got mapped by the
inferior) fails. For instance, with any Ada program:

    (gdb)
    -catch-exception -e program_error
    ^done,bkptno="1",bkpt={[...]}
    (gdb)
    -exec-run
    =thread-group-started,id="i1",pid="28315"
    =thread-created,id="1",group-id="i1"
    ^running
    *running,thread-id="all"
    (gdb)
    =library-loaded,[...]
    &"warning: failed to reevaluate internal exception condition for catchpoint 1: No definition of \"exec\" in current context.\n"
    &"warning: failed to reevaluate internal exception condition for catchpoint 1: No definition of \"exec\" in current context.\n"
    [...]

The same is true if using an Ada exception catchpoint.

The problem comes from the fact that that we deallocate the strings
given as arguments to create_ada_exception_catchpoint, while the latter
just makes shallow copies of those strings, thus creating dandling
pointers.

This patch fixes the issue by passing freshly allocated strings to
create_ada_exception_catchpoint, while at the same time updating
create_ada_exception_catchpoint's documentation to make it clear
that deallocating the strings is no longer the responsibility of
the caller.

Now that the configury needed for the "common" and "target"
directories is in common.m4, some code in gdb's configure.ac is
redundant.

I ran this script after making an "ID" file using mkid:

   sed -n 's/^.*\(HAVE_[A-Z0-9_]*\).*$/\1/p' config.in |

makes it clear which defines aren't used in the main parts of gdb.

From this I came up with this patch to remove all the unused bits.

There are a few that are subtly used -- for example the configure

This patch introduces common/common.m4 which consolidates the checks

10 years agoconstify to_detach
Tom Tromey [Tue, 19 Mar 2013 15:23:17 +0000 (09:23 -0600)] 
constify to_detach

This patch constifies the target_ops method to_detach.

This is a small cleanup, but also, I think, a bug-prevention fix,
since gdb already acts as if the "args" argument here was const.

In particular, top.c:quit_force calls kill_or_detach via
iterate_over_inferiors.  kill_or_detach calls target_detach, passing
the same argument each time.  So, if one of these methods was not
const-correct, then kill_or_detach would change its behavior in a
strange way.

I could not build every target I modified in this patch.  I've
inspected them all by hand, though.  Many targets do not use the
"args" parameter; a couple pass it to atoi; and a few pass it on to
the to_detach method of the target beneath.  The only code that
required a real change was in linux-nat.c, and that only needed the
introduction of a temporary variable for const-correctness.

S390: Fix TDB regset recognition

interprets ENODATA from PTRACE_GETREGSET as an indication that the TDB
regset *could* occur on this system, but the inferior stopped outside

even on systems without the transactional execution facility.  Thus

results, and how are they saved.  reporter.py is about how results
are reported (in what format).  measure.py is about measuring the
execution of tests by a collection of measurements.

In V5:
 - Simplify perftest.exp.

In V4:

 - Rename MeasurementCPUTime to MeasurementCpuTime,
 - Add 'pass' in empty method,
 - Simplify string comparison in perftest.exp.
 - Rename GDB_PERFORMANCE to GDB_PERFTEST_MODE and rename
   GDB_PERFORMANCE_TIMEOUT to GDB_PERFTEST_TIMEOUT.

In V3, there are some changes,

 - Add wall time measurement, cpu time measurement and vmsize
   measurement.
 - Rename SingleStatisticTestCase to TestCaseWithBasicMeasurements,
   which measures cpu time, wall time, and memory (vmsize).
 - GDB_PERFORMANCE=run|compile|both to control the mode of perf
   testing.
 - New GDB_PERFORMANCE_TIMEOUT to specify the timeout.
 - Split proc prepare to proc compile and startup.
 - Disable GC while doing measurements.

In V2, there are several changes to address Doug and Sanimir's
comments.

 - Add copyright header and docstring in perftest/__init__.py
 - Remove config.py.
 - Fix docstring format.
 - Rename classes "SingleVariable" to "SingleStatistic".
 - Don't extend gdb.Function in class TestCase.  Add a new method run
   to run the test case so that we can pass parameters to test.
 - Allow to customize whether to warm up and to append test log.
 - Move time measurement into test harness.  Add a new class
   Measurement for a specific measurement and a new class Measure to
   measure them for a given test case.
 - A new class ResultFactory to create instances of TestResult.
 - New file lib/perftest.exp, which is to do some preparations and
   cleanups to simplify each *.exp file.
 - Skip compilation step if GDB_PERFORMANCE_SKIP_COMPILE is set.

10 years agoNew make target 'check-perf' and new dir gdb.perf
Yao Qi [Wed, 25 Sep 2013 04:41:45 +0000 (12:41 +0800)] 
New make target 'check-perf' and new dir gdb.perf

We add a new dir gdb.perf in testsuite for all performance tests.
However, current 'make check' logic will either run dejagnu in
directory testsuite or iterate all gdb.* directories which has *.exp
files.  Both of them will run tests in gdb.perf.  We want to achieve:

 1) typical 'make check' should not run performance tests.  In each perf
    test case, GDB_PERFTEST_MODE is checked.  If it doesn't exist, return.
 2) run perf tests easily.  We add a new makefile target 'check-perf'.
