Fix PR breakpoints/16297: catch syscall with syscall 0

Code rationale
==============
by: Gabriel Krisman Bertazi

This is a fix for bug 16297. The problem occurs when the user attempts
to catch any syscall 0 (such as syscall read on Linux/x86_64). GDB was
not able to catch the syscall and was missing the breakpoint.

Now, breakpoint_hit_catch_syscall returns immediately when it finds the
correct syscall number, avoiding a following check for the end of the
search vector, that returns a no hit if the syscall number was zero.

Testcase rationale
==================
by: Sergio Durigan Junior

This testcase is a little difficult to write.  By doing a quick
inspection at the Linux source, one can see that, in many targets, the
syscall number 0 is restart_syscall, which is forbidden to be called
from userspace.  Therefore, on many targets, there's just no way to test
this safely.

My decision was to take the simpler route and just adds the "read"
syscall on the default test.  Its number on x86_64 is zero, which is
"good enough" since many people here do their tests on x86_64 anyway and
it is a popular architecture.

However, there was another little gotcha.  When using "read" passing 0
as the third parameter (i.e., asking it to read 0 bytes), current libc
implementations could choose not to effectively call the syscall.
Therefore, the best solution was to create a temporary pipe, write 1
byte into it, and then read this byte from it.

Improve and fix catch-syscall.exp

While fixing another bug, I found that the current
gdb.base/catch-syscall.exp is kind of messy, could use some
improvements, and is not correctly testing some things.

I've made the following patch to address all the issues I found.  On the
organization side, it does a cleanup and removes unecessary imports of
gdb_prompt, uses prepare_for_testing and clean_restart where needed, and
fixes some comments.  The testcase was also not correctly testing
catching syscalls using only numbers, or catching many syscalls at
once.  I fixed that.

The patch also uses a new method for obtaining the syscalls numbers: it
relies on the C source file to get them, via <sys/syscall.h> and SYS_*
macros.  This makes the .exp file simpler because there is no need to
include target conditionals there.

Like when stepping, the current stack frame location is expected to be
printed as result of tfind command, if that results in moving to a
different function.  In tfind_1 we see:

         function and it's arguments) -- otherwise we'll just show the
         new source line.  */

      if (frame_id_eq (old_frame_id,

        print_what = SRC_AND_LOC;

      print_stack_frame (get_selected_frame (NULL), 1, print_what, 1);
      do_displays ();
    }

However, when we haven't collected any registers in the tracepoint
(collect $regs), that doesn't actually work:

 (gdb) tstart
 (gdb) info tracepoints
 Num     Type           Disp Enb Address    What

 Found trace frame 1, tracepoint 2
 32    }
 (gdb)

When we don't have info about the stack available
(UNWIND_UNAVAILABLE), frames end up with outer_frame_id as frame ID.
And in the scenario above, the issue is that both frames before and
after the second tfind (the frames for func0 an func1) have the same
id (outer_frame_id), so the frame_id_eq check returns false, even
though the frames were of different functions.  GDB knows that,
because the PC is inferred from the tracepoint's address, even if no
registers were collected.

To fix this, this patch adds support for frame ids with a valid code
address, but <unavailable> stack address, and then makes the unwinders
use that instead of the catch-all outer_frame_id for such frames.  The
frame_id_eq check in tfind_1 then automatically does the right thing
as expected.

I tested with --directory=gdb.trace/ , before/after the patch, and
compared the resulting gdb.logs, then adjusted the tests to expect the
extra output that came out.  Turns out that was only circ.exp, the
original test that actually brought this issue to light.

The visible symptom is that ntdll.dll is missing from the list of

10 years agowrong dimension found in ada-lang.c:ada_array_bound_from_type
Joel Brobecker [Wed, 27 Nov 2013 13:42:24 +0000 (17:42 +0400)]
wrong dimension found in ada-lang.c:ada_array_bound_from_type

This function has the following code:

  elt_type = type;
  for (i = n; i > 1; i--)
    elt_type = TYPE_TARGET_TYPE (type);

For multi-dimension arrays, the code above tries to find the array
type corresponding to the dimension we're trying to inspect.
The problem is that, past the second dimension, the loop does
nothing other than repeat the first iteration. There is a little
thinko where it got the TYPE_TARGET_TYPE of TYPE instead of ELT_TYPE!

To my surprise, I was unable to produce an Ada exemple that demonstrated
the problem.  That's because the examples I created all trigger a parallel
___XA type which we then use in place of the ELT_TYPE in order to
determine the bounds - see the code that immediately follows our
loop above:

    index_type_desc = ada_find_parallel_type (type, "___XA");
    ada_fixup_array_indexes_type (index_type_desc);
    if (index_type_desc != NULL)
    [...]

So, in order to avoid depending on an Ada example where the compiler
can potentially decide one way or the other, I decided to use an
artificial example, written in C. With ...

  int multi[1][2][3];

... forcing the language to Ada, and trying to print the 'last,
we get:

    (gdb) p multi'last(1)
    $1 = 0
    (gdb) p multi'last(2)
    $2 = 1
    (gdb) p multi'last(3)
    $3 = 1   <<<---  This should be 2!

Additionally, I noticed that a couple of check_typedef's were missing.
This patch adds them. And since the variable in question only gets
used within an "else" block, I moved the variable declaration and
use inside that block - making it clear what the scope of the variable
is.

gdb/ChangeLog:

        * ada-lang.c (ada_array_bound_from_type): Move the declaration
        and assignment of variable "elt_type" inside the else block
        where it is used.  Add two missing check_typedef calls.
        Fix bug where we got TYPE's TYPE_TARGET_TYPE, where in fact
        we really wanted to get ELT_TYPE's TYPE_TARGET_TYPE.

Eliminate UNSUPPORTED_ERROR.

I have a case that could use an exception for "unsupported feature".
I found UNSUPPORTED_ERROR, but looking deeper, I think as is, reusing
it for other things would be fragile.  E.g., if the Python script
sourced by source_script_from_stream triggers any other missing
functionality that would result in UNSUPPORTED_ERROR being propagated
out to source_script_from_stream, that would confuse the error for
Python not being built into GDB.

This patch thus redoes things a little.  Instead of using an exception
for the "No Python" scenario, check whether Python is configured in
before actually trying to source the file.  It adds a new function
instead of using #ifdef HAVE_PYTHON directly, as that is better at
avoiding bitrot, as both Python and !Python paths are visible to the
compiler this way.

Sanitize access to gdbarch on the SDT probe API (and fix ARM bug)

This patch sanitizes the access to gdbarch made by various functions of
the SDT probe API.  Before this patch, gdbarch was being accessed via
the probe's objfile; however, this proved to cause a bug on 32-bit ARM
targets because during the parsing of the probe's arguments the code
needed to access some pseudo-registers of the architecture, and this
information is not fully correct on the objfile's gdbarch.

Basically, the approach taken was to instead pass the current/selected
frame to the parsing and evaluation functions, so that they can extract
the gdbarch directly from the frame.  It solved the ARM bug reported
above, and also contributed to make the API cleaner.
