11 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.

Add command to list Ada exceptions

This patch adds a new command "info exceptions" whose purpose is to
provide the list of exceptions currently defined in the inferior.
The usage is:

    (gdb) info exceptions [REGEXP]

Without argument, the command lists all exceptions.  Otherwise,
only those whose name match REGEXP are listed.

For instance:

    (gdb) info exceptions
    All defined Ada exceptions:

I inherited long ago. It's output being parsed by frontends such as
GPS, I cannot easily change it. Same for the command name.

The implementation is mostly self-contained, and is written in a way
that should make it easy to implement the GDB/MI equivalent. The
careful reviewer will notice that the code added in ada-lang.h could
normally be made private inside ada-lang.c.  But these will be used
by the GDB/MI implementation.  Rather than making those private now,
only to move them later, I've made them public right away.

Dandling memory pointers in Ada catchpoints with GDB/MI.

Ada exception, any re-evaluation of that catchpoint (for instance
a re-evaluation performed after a shared library got mapped by the

gdb configure updates

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 |
   while read x; do
     echo ===== $x
     gid $x | egrep -v '^(testsuite|gnulib|common|target|gdbserver)/'
   done

This finds all the spots using HAVE_ defines, and, more importantly,
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
script sometimes checks internal configure cache variables, meaning
some checks cannot be removed.

introduce common.m4

defined via autoconf checks, but rely on each configure.ac doing the
proper checks independently.

This patch introduces common/common.m4 which consolidates the checks
assumed by code in common.

The rule I propose is that if something is needed or used by common,
it should be checked for by common.m4.  However, if the check is also
needed by gdb or gdbserver, then it should be duplicated there.

Built and regtested on x86-64 Fedora 18 (though this is hardly the
most strenuous case) and using the Fedora 18 mingw cross compilers.  I

missing.

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
a transaction.  However, the Linux kernel actually reports ENODATA
even on systems without the transactional execution facility.  Thus
the logic is now changed to check the TE field in the HWCAP as well.

This version also checks the existence of the TDB regset -- just to be

that does not offer the TDB regset for some reason.

11 years agoswitch to fully parallel mode
Tom Tromey [Tue, 27 Aug 2013 17:52:25 +0000 (11:52 -0600)]
switch to fully parallel mode

This switches "make check" to fully parallel mode.

One primary issue facing full parallelization is the overhead of
"runtest".  On my machine, if I "touch gdb.base/empty.exp", making a
new file, and then "time runtest.exp", it takes 0.08 seconds.

Multiply this by the 1008 (in my configuration) tests and you get ~80
seconds.  This is the overhead that would theoretically be present if
all tests were run in parallel.

However, the problem isn't nearly as bad as this, for two reasons.

First, you must divide by the number of jobs, assuming perfect
parallelization -- reasonably true for small -j numbers, based on the
results I see.

Second, the current test suite parallelization approach bundles the
tests, largely by directory, but also splitting up gdb.base into two
halves.

I was curious to see how the current bundling played out in practice,
so I ran "make -j1 check RUNTEST='/bin/time runtest'".  This invokes
the parallel mode (thus the bundling) and then shows the time taken by
each invocation of runtest.

Then, I ran "/bin/time make -j3 check".  (See below about -j2.)

The time for the entire -j3 test run was the same as the time for
"gdb.base1".  What this means is that gdb.base1 is currently the
time-limiting run, preventing further parallelization gains.

So, I reason, whatever overhead we see from full parallelization will
only be seen by "-j1" and "-j2".

I then tried a -j2 test run.  This does take longer than a -j3 build,
meaning that the gdb.base1 job finishes and then proceeds to other
runtest invocations.

Finally I tried a -j2 test run with the appended patch.
This was 9% slower than the -j2 run without the patch.

I think that is a reasonable slowdown for what is probably a rare
case.  I believe this patch will yield faster test results for all -j
values greater than 2.  For -j3 on my machine, the test suite is a few
seconds faster; I didn't try any larger -j values.

For -j1, I went ahead and changed the Makefile so that, if no -j
option is given, then the "check-single" mode is used.  You can still
use "make -j1 check" to get single-job parallel-mode, though of course
there's no good reason to do so.

This change is likely to speed up the plain "make check" scenario a
little as we will now bypass dg-extract-results.sh.

One drawback of this change is that "make -jN check" is now much more
verbose.  I generally only look at the .sum and .log files, but
perhaps this will bother some.

Another interesting question is scalability of the result.  The
slowest test, which limits the scalability, took 80.78 seconds.  The
mean of the remaining tests is 1.08 seconds.  (Note that this is just
a rough estimate, since there are still outliers.)

This means we can run 80.78 / 1.08 =~ 74 tests in the time available.
And, in this data set (slightly older than the above, but materially
the same) there were 948 tests.  So, I think the current test suite
should scale ok up to about -j12.

We could improve this number if need be by breaking up the biggest
tests.
