11 years agoStop using errno values around target_xfer interfaces and memory errors.
Pedro Alves [Wed, 9 Oct 2013 17:00:00 +0000 (17:00 +0000)]
Stop using errno values around target_xfer interfaces and memory errors.

target_read_memory & friends build on top of target_read (thus on top
of the target_xfer machinery), but turn all errors to EIO, an errno
value.  I think we'd better convert all these to return a
target_xfer_error too, like target_xfer_partial in a previous patch.
The patch starts by doing that.

(The patch does not add a enum target_xfer_error value for '0'/no
error, and likewise does not change the return type of several of
these functions to enum target_xfer_error, because different functions
return '0' with different semantics.)

I audited the tree for memory_error calls, EIO checks, places where
GDB hardcodes 'errno = EIO', and also for strerror calls.  What I
found is that nowadays there's really no need to handle random errno
values, other than the EIOs gdb itself hardcodes.  No doubt errno
values would appear in common code back in the day when
target_xfer_memory was the main interface to access memory, but
nowadays, any errno value that deprecated interface could return is
just absorved by default_xfer_partial:

      else if (xfered == 0 && errno == 0)
/* "deprecated_xfer_memory" uses 0, cross checked against
           ERRNO as one indication of an error.  */
return 0;
      else
return -1;

There are two places in the code that check for EIO and print "out of
bounds", and defer to strerror for other errors.  That's
c-lang.c:c_get_string, and valprint.c.:val_print_string.  AFAICT, the
strerror branch can never be reached nowadays, as the only error
possible to get at those points is EIO, given that it's GDB itself
that set that errno value (in target_read_memory, etc.).

breakpoint.c:insert_bp_location always prints the error val as if an
errno, returned by target_insert_breakpoint, with strerr.  Now the
error here is either always EIO for mem-break.c targets (again
hardcoded by the target_read_memory/target_write_memory functions), so
this always prints "Input/output error" or similar (depending on
host), or, for remote targets (and probably others), this gem:

  Error accessing memory address 0x80200400: Unknown error -1.

This patch makes these 3 places print the exact same error
memory_error prints.  This changes output, but I think this is better,
for making memory error output consistent with other commands, and, it
means we have a central place to tweak for memory errors.

E.g., this changes:

 Cannot insert breakpoint 1.
 Error accessing memory address 0x5fc660: Input/output error.

to:

 Cannot insert breakpoint 1.
 Cannot access memory at address 0x5fc660

Which I find pretty much acceptable.

Surprisingly, only py-prettyprint.exp had a regression, for needing an
adjustment.  I also grepped the testsuite for the old errors, and
found no other hits.

Now that errno values aren't used anywhere in any of these memory
access related routines, I made memory_error itself take a
target_xfer_error instead of an errno.  The new
target_xfer_memory_error function added recently is no longer
necessary, and is thus removed.

Tested on x86_64 Fedora 17, native and gdbserver.

fix PR symtab/15597

This patch fixes gdb PR symtab/15597.

The bug is that the .gnu_debugaltlink section includes the build-id of
the alt file, but gdb does not use it.

This patch fixes the problem by changing gdb to do what it ought to
always have done: verify the build id of the file found using the
filename in .gnu_debugaltlink; and if that does not match, try to find
the correct debug file using the build-id and debug-file-directory.

This patch touches BFD.  Previously, gdb had its own code for parsing
.gnu_debugaltlink; I changed it to use the BFD functions after those
were introduced.  However, the BFD functions are incorrect -- they
assume that .gnu_debugaltlink is formatted like .gnu_debuglink.
However, it it is not.  Instead, it consists of a file name followed
by the build-id -- no alignment, and the build-id is not a CRC.

Fixing this properly is a bit of a pain.  But, because
separate_alt_debug_file_exists just has a FIXME for the build-id case,
I did not fix it properly.  Instead I introduced a hack.  This leaves
BFD working just as well as it did before my patch.

I'm willing to do something better here but I could use some guidance
as to what.  It seems that the build-id code in BFD is largely punted
on.

FWIW gdb is the only user of bfd_get_alt_debug_link_info outside of
BFD itself.

I moved the build-id logic out of elfread.c and into a new file.
This seemed cleanest to me.

Writing a test case was a bit of a pain.  I added a couple new
features to the DWARF assembler to handle this.

[Ada] psymbol search failure due to comparison function discrepancy

Upon trying to print the value of a variant record, a user noticed
the following problem:

        (gdb) print rt
        warning: Unknown upper bound, using 1.
        warning: Unknown upper bound, using 1.
        $1 = (a => ((a1 => (4), a2 => (4)), (a1 => (8), a2 => (8))))

The expected output is:

        (gdb) print rt
        $1 = (a => ((a1 => (4, 4), a2 => (8, 8)), (a1 => (4, 4),
              a2 => (8, 8))))

The problems comes from the fact that components "a1" and "a2" are
defined as arrays whose upper bound is dynamic.  To determine the value
of that upper bound, GDB relies on the GNAT encoding and searches
for the parallel ___U variable.  Unfortunately, the search fails
while doing a binary search inside the partial symtab of the unit
where the array and its bound (and therefore the parallel ___U variable)
are defined.

It fails because partial symbols are sorted using strcmp_iw_ordered,
while Ada symbol lookups are performed using a different comparison
function (ada-lang.c:compare_names). The two functions are supposed
to be compatible, but a change performed in April 2011 modified
strcmp_iw_ordered, introducing case-sensitivity issues. As a result,
the two functions would now disagree when passed the following
two arguments:

  string1="common__inner_arr___SIZE_A_UNIT"
  string2="common__inner_arr__T4s___U"

The difference starts at "_SIZE_A_UNIT" vs "T4s___U". So, it's mostly
a matter of comparing '_' with 'T'.

On the one hand, strcmp_iw_ordered would return -1, while compare_names
returned 11. The change that made all the difference is that
strcmp_iw_ordered now performs a case-insensitive comparison,
and only resorts to case-sentitive comparison if the first comparison
finds an equality. This changes everything, because while 'T' (84)
and 't' (116) are on opposite sides of '_' (95).

This patch aims at restoring the compatibility between the two
functions, by adding case-sensitivity handling in the Ada comparison
function.

gdb/ChangeLog:

        * ada-lang.c (compare_names_with_case): Renamed from

don't share per-BFD data if relocations are needed

Right now we always share per-BFD data across objfiles, if there is a
BFD.  This works fine.  However, we're going to start sharing more
data, and sometimes this data will come directly from sections of the
BFD.  If such a section has SEC_RELOC set, then the data coming from
that section will not be truly sharable -- the section will be
program-space-dependent, and re-read by gdb for each objfile.

This patch disallows per-BFD sharing in this case.  This is a bit
"heavy" in that we could in theory examine each bit of shared data for
suitability.  However, that is more complicated, and SEC_RELOC is rare
enough that I think we needn't bother.

Note that the "no sharing" case is equivalent to "gdb works as it
historically did".  That is, the sharing is a new(-ish) optimization.

This patch  adds a new convenience variable called "$_exitsignal", which
will hold the signal number when the inferior terminates due to the

I've made modifications on infrun.c:handle_inferior_event such that
$_exitcode gets cleared when the inferior signalled, and vice-versa.
This assumption was made because the variables are mutually
exclusive, i.e., when the inferior terminates because of an uncaught
signal it is not possible for it to return.  I have also made modifications
such that when a corefile is loaded, $_exitsignal gets set to the uncaught
signal that "killed" the inferior, and $_exitcode is cleared.

The patch also adds a NEWS entry, documentation bits, and a testcase.  The
documentation entry explains how to use $_exitsignal and $_exitcode in a

Clean up ptid.h/ptid.c.

The ptid_t contructors, accessors and predicates are documented in
_three_ places, and each place uses a different wording.

E.g, the descriptions in the .c file of the new ptid_lwp_p, ptid_tid_p
weren't updated in the final revision like the descriptions in the .h
file were.  Clearly, switching to a style that has a single central
description avoids such issues.

Worse, some of the existing descriptions are plain wrong, such as:

  /* Attempt to find and return an existing ptid with the given PID, LWP,
     and TID components.  If none exists, create a new one and return
     that.  */
  ptid_t ptid_build (int pid, long lwp, long tid);

The function does nothing that complicated.  It's just a simple
constructor.

So this gets rid of all the unnecessary descriptions, leaving only the
ones near the function declarations in the header file, and
fixes/clarifies those that remain.

Always run the PTRACE_O_TRACESYSGOOD tests even if PTRACE_O_TRACEFORK is not supported.

If enabling PTRACE_O_TRACEFORK fails, we never test for
PTRACE_O_TRACESYSGOOD support.  Before PTRACE_O_TRACESYSGOOD is checked,
we have:

  /* First, set the PTRACE_O_TRACEFORK option.  If this fails, we
     know for sure that it is not supported.  */
  ret = ptrace (PTRACE_SETOPTIONS, child_pid, (PTRACE_TYPE_ARG3) 0,
(PTRACE_TYPE_ARG4) PTRACE_O_TRACEFORK);

  if (ret != 0)
    {
      ret = ptrace (PTRACE_KILL, child_pid, (PTRACE_TYPE_ARG3) 0,
    (PTRACE_TYPE_ARG4) 0);
      if (ret != 0)
{
  warning (_("linux_check_ptrace_features: failed to kill child"));
  return;
}

      ret = my_waitpid (child_pid, &status, 0);
      if (ret != child_pid)
warning (_("linux_check_ptrace_features: failed "
   "to wait for killed child"));
      else if (!WIFSIGNALED (status))
warning (_("linux_check_ptrace_features: unexpected "
   "wait status 0x%x from killed child"), status);

      return; <<<<<<<<<<<<<<<<<
    }

Note that early return.  If PTRACE_O_TRACEFORK isn't supported, we're
not checking PTRACE_O_TRACESYSGOOD.  This didn't use to be a problem
before the unification of this whole detection business in
linux-ptrace.c.  Before, the sysgood detection was completely
separate:

static void
linux_test_for_tracesysgood (int original_pid)
{
  int ret;
  sigset_t prev_mask;

  /* We don't want those ptrace calls to be interrupted.  */
  block_child_signals (&prev_mask);

  linux_supports_tracesysgood_flag = 0;

  ret = ptrace (PTRACE_SETOPTIONS, original_pid, 0, PTRACE_O_TRACESYSGOOD);
  if (ret != 0)
    goto out;

  linux_supports_tracesysgood_flag = 1;
out:
  restore_child_signals_mask (&prev_mask);
}

So we need to get back the decoupling somehow.  I think it's cleaner
to split the seperate feature detections to separate functions.  This
patch does that.  The new functions are named for their counterparts
that existed before this code was moved to linux-ptrace.c.

Note I've used forward declarations for the new functions to make the
patch clearer, as otherwise the patch would look like I'd be adding a
bunch of new code.  A reorder can be done in a follow up patch.

11 years agoPrint registers not saved in the frame as "<not saved>" instead of "<optimized out>".
Pedro Alves [Wed, 2 Oct 2013 16:15:46 +0000 (16:15 +0000)]
Print registers not saved in the frame as "<not saved>" instead of "<optimized out>".

Currently, in some scenarios, GDB prints <optimized out> when printing
outer frame registers.  An <optimized out> register is a confusing
concept.  What this really means is that the register is
call-clobbered, or IOW, not saved by the callee.  This patch makes GDB
say that instead.

Before patch:

 (gdb) p/x $rax $1 = <optimized out>
 (gdb) info registers rax
 rax            <optimized out>

After patch:

 (gdb) p/x $rax
 $1 = <not saved>
 (gdb) info registers rax
 rax            <not saved>

However, if for some reason the debug info describes a variable as
being in such a register (**), we still want to print <optimized out>
when printing the variable.  IOW, <not saved> is reserved for
inspecting registers at the machine level.  The patch uses
lval_register+optimized_out to encode the not saved registers, and
makes it so that optimized out variables always end up in
!lval_register values.

** See <https://sourceware.org/ml/gdb-patches/2012-08/msg00787.html>.
Current/recent enough GCC doesn't mark variables/arguments as being in
call-clobbered registers in the ranges corresponding to function
calls, while older GCCs did.  Newer GCCs will just not say where the
variable is, so GDB will end up realizing the variable is optimized
out.

frame_unwind_got_optimized creates not_lval optimized out registers,
so by default, in most cases, we'll see <optimized out>.

value_of_register is the function eval.c uses for evaluating
OP_REGISTER (again, $pc, etc.), and related bits.  It isn't used for
anything else.  This function makes sure to return lval_register
values.  The patch makes "info registers" and the MI equivalent use it
too.  I think it just makes a lot of sense, as this makes it so that
when printing machine registers ($pc, etc.), we go through a central
function.

We're likely to need a different encoding at some point, if/when we
support partially saved registers.  Even then, I think
value_of_register will still be the spot to tag the intention to print
machine register values differently.

value_from_register however may also return optimized out
lval_register values, so at a couple places where we're computing a
variable's location from a dwarf expression, we convert the resulting
value away from lval_register to a regular optimized out value.

Pedro Alves [Wed, 2 Oct 2013 11:44:20 +0000 (11:44 +0000)]
Teach the testsuite that GDBserver reliably reports program exits.

Running catch-syscall.exp against a gdbserver that actually supports
it, we get:

 FAIL: gdb.base/catch-syscall.exp: continue until exit (the program exited)
 FAIL: gdb.base/catch-syscall.exp: continue until exit (the program exited)

 FAIL: gdb.base/catch-syscall.exp: continue until exit (the program exited)

The fail pattern is:

 Catchpoint 2 (call to syscall exit_group), 0x000000323d4baa29 in _exit () from /lib64/libc.so.6
 (gdb) PASS: gdb.base/catch-syscall.exp: program has called exit_group

 Delete all breakpoints? (y or n) y

 Breakpoint 3 at 0x323d438bf0
 (gdb) continue
 Continuing.
 [Inferior 1 (process 21081) exited normally]

That "break exit" + "continue" comes from:

> # gdb_continue_to_end:
> # The case where the target uses stubs has to be handled specially. If a
> #       stub is used, we set a breakpoint at exit because we cannot rely on
> #       exit() behavior of a remote target.
> #

The native-gdbserver.exp board, used to test against gdbserver in
"target remote" mode, triggers that case ($use_gdb_stub is true).  So
gdb_continue_to_end doesn't work for catch-syscall.exp as here we
catch the exit_group and continue from that, expecting to see a real
program exit.  I was about to post a patch that changes
catch-syscall.exp to call a new function that just always does what
gdb_continue_to_end does in the !$use_gdb_stub case.  But, since
GDBserver doesn't really need this, in the end I thought it better to
teach the testsuite that there are stubs that know how to report
program exits, by adding a new "exit_is_reliable" board variable that
then gdb_continue_to_end checks.

This is what the log shows for all of them:

 (gdb) continue
 Continuing.

 GDBserver exiting
 [Inferior 1 (process 22721) exited normally]
 (gdb) FAIL: gdb.arch/amd64-disp-step.exp: continue until exit (the program exited)

The problem is the whole "Child exited ... GDBserver exiting" output,
that comes out of GDBserver, and that the testsuite is not expecting.

I pondered somehow making the testsuite adjust to this.  But,
testsuite aside, I think GDBserver should not be outputting this at
all when GDB is connected through stdio.  GDBserver will be printing
this in GDB's console, but the user can already tell from the regular
output that the inferior is gone.

Again, manually:

 (gdb) tar remote | ./gdbserver/gdbserver - program
 Remote debugging using | ./gdbserver/gdbserver - program
 Process program created; pid = 22486

 ^^^^^^^^^^^^^^^^^^^^^^^^^^

 ^^^^^^^^^^^^^^^^^
 [Inferior 1 (process 22486) exited with code 01]

Suppressing those two lines makes the output be exactly like when
debugging against a remote tcp gdbserver:

 (gdb) c
 Continuing.
