9 years agopreserve the bit stride when resolving an array type.
Joel Brobecker [Tue, 31 Mar 2015 14:59:35 +0000 (07:59 -0700)]
preserve the bit stride when resolving an array type.

Consider the following (Ada) variable...

   A1 : Array_Type := (1 => (I => 0, S => <>),
                       2 => (I => 1, S => "A"),
                       3 => (I => 2, S => "AB"));

... where Array_Type is an array of records whose size is variable:

   subtype Small_Type is Integer range 0 .. 10;
   type Record_Type (I : Small_Type := 0) is record
      S : String (1 .. I);
   end record;
   type Array_Type is array (Integer range <>) of Record_Type;

Trying to print the value of this array currently results in the following
error:

    (gdb) p a1
    Cannot access memory at address 0x61c000

What happens in this case, is that the compiler describes our array
as an array with a specific stride (and bounds being static 1..3):

 <1><749>: Abbrev Number: 10 (DW_TAG_array_type)
    <74a>   DW_AT_name        : (indirect string, offset: 0xb6d): pck__T18s
    <74e>   DW_AT_byte_stride : 16
    <74f>   DW_AT_type        : <0x6ea>
 <2><757>: Abbrev Number: 11 (DW_TAG_subrange_type)
    <758>   DW_AT_type        : <0x75e>
    <75c>   DW_AT_upper_bound : 3

This is because we cannot use, in this case, the size of the record
to determine that stride, since the size of the record depends on
its contents. So the compiler helps us by providing that stride.

The problems start when trying to resolve that type. Because the elements
contained in that array type are dynamic, the array itself is considered
dynamic, and thus we end up creating a resolved version of that array.
And during that resolution, we were not handling the case where the array
had a stride. See gdbtypes.c::resolve_dynamic_array...

  return create_array_type (copy_type (type),
                            elt_type,
                            range_type);

As a result, we created an array whose stride was based on the size
of elt_type, which a record whose size isn't static and irrelevant
regardless.

This patch fixes is by calling create_array_type_with_stride instead.

As it happens, there is another issue for us to be able to print
the value of our array, but those are independent of this patch
and will be handled separately. For now, the patch allows us to
get rid of the first error, and the output is now:

     (gdb) p a1
     $1 = (

 (gdb) FAIL: gdb.base/relativedebug.exp: pause found in backtrace

if glibc has debug info, this test doesn't fail.

In sysdeps/unix/sysv/linux/generic/pause.c, __libc_pause calls
__syscall_pause,

  static int
  __syscall_pause (void)
  {
    sigset_t set;

    int rc =

    if (SINGLE_THREAD_P)
      return __syscall_pause ();     <--- tail call

    int oldtype = LIBC_CANCEL_ASYNC ();

    int result = __syscall_pause ();

    LIBC_CANCEL_RESET (oldtype);

    return result;
  }

and GDB unwinder is confused by the GCC optimized code,

(gdb) disassemble pause

Note that the program stops in __syscall_pause, but its symbol is
stripped in glibc, so GDB doesn't know where the program stops.
__syscall_pause is a tail call in __libc_pause, so it returns to main
instead of __libc_pause.  As a result, the backtrace is like,

 #0  0x0000007fb7ebca88 in raise () from /lib/aarch64-linux-gnu/libc.so.6

looks GDB does nothing wrong here.  I looked back at the test case
gdb.base/relativedebug.exp, which was added
https://sourceware.org/ml/gdb-patches/2006-10/msg00305.html
This test was indented to test the problem that "backtraces no longer
display some libc functions" after separate debug info is installed.
IOW, it makes few sense to test against libc which doesn't have debug
info at all, such as my case.

This patch is to tweak the test case to catch the output of
"info shared", if "(*)" is found for libc.so, which means libc doesn't
have debug info, then skip the test.

For no good reason the function tui_free_window() is freeing the locator
window when we pass it an SRC_WIN or a DISASSEM_WIN.  This behavior
doesn't make much sense because the locator window is always visible and
its contents do not change when the main window changes.

This behavior triggers the above PR because when we switch from one TUI

call tui_free_window() on the previously active window (in the PR, the

Enable fork tracing for native FreeBSD targets.

Enable PT_FOLLOW_FORK on all processes.  When this is enabled, both
the parent and child process stop when a fork or vfork occurs.

A target operation for wait uses PT_LWPINFO to fetch more detailed
information about the state of a stopped process.  A parent process
sets the PL_FLAG_FORKED flag in the pl_flags field of the structure
returned by PT_LWPINFO as well as the pid of the new child process.
The child process sets the PL_FLAG_CHILD flag in the pl_flags field.

When a fork is detected, the wait hook waits for both processes to
report their respective events.  It then reports the fork to GDB as
a single TARGET_WAITKIND_FORKED or TARGET_WAITKIND_VFORKED event.
The kernel does not guarantee the order the events are reported in.
If the parent process' event is reported first, then the wait hook
explicitly waits for the child process.  If the child process' event
is reported first, the event is recorded on an internal list of
pending child events and the wait hook waits for another event.
Later when the parent process' event is reported, the parent will
use the previously-recorded child process event instead of explicitly
waiting on the child process.

To distinguish vfork events from fork events, the external process
structure for the child process is extracted from the kernel.  The
P_PPWAIT flag is set in the ki_flags field of this structure if the
process was created via vfork, but it is not set for a regular fork.

which returned non-zero ("true") if the argument was zero.  This led
to a wrong decision when passing a zero-sized struct in an inferior
function call.

  false if the argument is zero.

9 years ago[Ada] Cache all static structures and reset cache during resolution
Pierre-Marie de Rodat [Mon, 27 Apr 2015 09:06:07 +0000 (11:06 +0200)]
[Ada] Cache all static structures and reset cache during resolution

Currently, ada-lang.c:template_to_static_fixed_type (working on
structure types only) caches its result into the unused TYPE_TARGET_TYPE
field. This introduces inconsistencies when the input type is
specialized, for instance during type resolution: the cached static
fixed type is copied along with the original type, but it's no longer
adapted to the copy once the copy is modified:
template_to_static_fixed_type has to compute another static fixed type
for it.

This change first introduces a cache reset during type resolution for
structure types so that this inconsistency does not happen anymore. It
also makes template_to_static_fixed_type smarter with respect to types
that do not need static fixed copies so that less computations is done
in general.

This inconsistency was spotted thanks to code reading, not because of
any sort of failure and we did not manage to exhibit a failure yet, so
no testcase for this.

gdb/ChangeLog:

* ada-lang.c (template_to_static_fixed_type): Return input type
when it is already fixed. Cache the input type itself when not
creating a static fixed copy. Make it explicit that we never
molestate the input type.
* gdbtypes.c (resolve_dynamic_struct): Reset the
TYPE_TARGET_TYPE field for resolved copies.

9 years ago[Ada] Preserve typedef layer when getting struct element
Joel Brobecker [Mon, 27 Apr 2015 09:04:47 +0000 (11:04 +0200)]
[Ada] Preserve typedef layer when getting struct element

Consider the following declarations:

   type Int_Access is access Integer;
   type Record_Type is record
      IA : Int_Access;
   end record;

   R : Record_Type;

Printing the type name of "R.IA" yields:

    (gdb) whatis r.ia
    type = access integer

It should be:

    (gdb) whatis r.ia
    type = bar.int_access

Looking at the debugging info, field "r.ia" is defined as
a typedef which has the name of the field type:

        .uleb128 0x3    # (DIE (0x4e) DW_TAG_typedef)
        .long   .LASF4  # DW_AT_name: "bar__int_access"
        .long   0x8b    # DW_AT_type

... with the typedef's target type being an anonymous pointer
type:

        .uleb128 0x7    # (DIE (0x8b) DW_TAG_pointer_type)
        .byte   0x8     # DW_AT_byte_size
        .long   0x91    # DW_AT_type

What happens here is that a couple of function in ada-lang.c
always start by stripping all typedef layers when handling
struct fields, with the effect of making us lose the type name
in this case.

We did not understand this at the time the code was written,
but typedefs should be stripped only when we know we do not
need them. So this patch, adjust the code to avoid the stripping
while handling the fields, and adds it back in the lone place
which handles the result of processing and didn't know how to
handle typedefs struct fields yet.

gdb/ChangeLog:

        * ada-lang.c (ada_is_tagged_type): Add call to ada_check_typedef.
