[Ada] Crash when trying to set value of packed array element
Consider the following declaration:
type Small is new Integer range 0 .. 2 ** 4 - 1;
type Simple_Array is array (1 .. 4) of Small;
pragma Pack (Simple_Array);
SA : Simple_Array := (1, 2, 3, 4);
Trying to change the value of one of the elements in the packed array
causes the debugger to crash:
(gdb) set sa(3) := 9
[1] 4880 segmentation fault gdb -q foo
The circumstances leading to the crash are as follow:
. ada_evaluate_subexp creates a value corresponding to "sa(3)".
. ada_evaluate_subexp then tries to assign 9 to this value, and
for this calls value_assign (via ada_value_assign).
. Because the array is packed, the destination value is 3 bits long,
and as a result, value_assign uses the parent to determine that
element byte address and offset:
| if (value_bitsize (toval))
| {
| struct value *parent = value_parent (toval);
|
| changed_addr = value_address (parent) + value_offset (toval);
The destination value (corresponding to "sa(3)") was incorrectly created
by ada-lang.c:ada_value_primitive_packed_val, because the "parent" was
left as NULL. So, when we try to dereference it to get the parent address,
GDB crashed.
The first part of the fix therefore consists in setting that field.
This required the addition of a new "setter" in value.[hc]. It fixes
the crash, but is still not sufficient for the assignment to actually
work.
The second part of the problem came from the fact that value_assign
seems to expect the "child"'s address to be equal to the parent's address,
with the difference being the offset. Unfortunately, this requirement was
not followed by ada_value_primitive_packed_val, so the second part of
the fix consisted in fixing that.
Still, this was not sufficient, because it caused a regression when
trying to perform an aggregate assignment of a packed array of packed
record. The key element here is the nesting of packed entities.
Looking at the way ada_value_primitive_packed_val creates the value
of each sub-component, one can see that the value's offset is set
to the offset compared to the start of the parent. This was meant to
match what value_primitive_field does as well.
So, with our array of records, if the record offset was 2, and if
the field we're interested in that record is at offset 1, the record
value's offset would be set to 2, and the field value's offset would
be set to 1. But the address for both values would be left to the
array's address. This is where things start breaking down, because
the value_address function for our field value would return the
address of the array + 1, instead of + 3.
This is what causes the final issue, here, because ada-lang.c's
value_assign_to_component needs to compute the offset of the
subcomponent compared to the top-level aggregate's start address
(the array in our case). And it does so by subtracting the array's
address from the sub-component's address. When you have two levels
of packed components, and the mid-level component is at an offset of
the top-level component, things didn't work, because the component's
address was miscomputed (the parent's offset is missing).
The fix consists is fixing value_address to match the work done by
value_primitive_field (where we ignore the parent's offset).
gdb/ChangeLog:
* value.h (set_value_parent): Add declaration.
* value.c (set_value_parent): New function.
(value_address): If VALUE->PARENT is not NULL, then use it as
the base address instead of VALUE->LOCATION.address.
* ada-lang.c (ada_value_primitive_packed_val): Keep V's address
the same as OBJ's address. Adjust V's offset accordingly.
Set V's parent.
gdb/testsuite/ChangeLog:
* gdb.ada/set_pckd_arr_elt: New testcase.

/* If a value represents a C++ object, then the `type' field gives the
|
|
|
|
|
object's compile-time type. If the object actually belongs to some
|
|
|
|
|
class derived from `type', perhaps with other base classes and
|
|
|
|
|
additional members, then `type' is just a subobject of the real
|
|
|
|
|
thing, and the full object is probably larger than `type' would
|
|
|
|
|
suggest.
|
|
|
|
|
|
|
|
|
|
If `type' is a dynamic class (i.e. one with a vtable), then GDB can
|
|
|
|
|
actually determine the object's run-time type by looking at the
|
|
|
|
|
run-time type information in the vtable. When this information is
|
|
|
|
|
available, we may elect to read in the entire object, for several
|
|
|
|
|
reasons:
|
|
|
|
|
|
|
|
|
|
- When printing the value, the user would probably rather see the
|
|
|
|
|
full object, not just the limited portion apparent from the
|
|
|
|
|
compile-time type.
|
|
|
|
|
|
|
|
|
|
- If `type' has virtual base classes, then even printing `type'
|
|
|
|
|
alone may require reaching outside the `type' portion of the
|
|
|
|
|
object to wherever the virtual base class has been stored.
|
|
|
|
|
|
|
|
|
|
When we store the entire object, `enclosing_type' is the run-time
|
|
|
|
|
type -- the complete object -- and `embedded_offset' is the offset
|
|
|
|
|
of `type' within that larger type, in bytes. The value_contents()
|
|
|
|
|
macro takes `embedded_offset' into account, so most GDB code
|
|
|
|
|
continues to see the `type' portion of the value, just as the
|
|
|
|
|
inferior would.
|
|
|
|
|
|
|
|
|
|
If `type' is a pointer to an object, then `enclosing_type' is a
|
|
|
|
|
pointer to the object's run-time type, and `pointed_to_offset' is
|
|
|
|
|
the offset in bytes from the full object to the pointed-to object
|
|
|
|
|
-- that is, the value `embedded_offset' would have if we followed
|
|
|
|
|
the pointer and fetched the complete object. (I don't really see
|
|
|
|
|
the point. Why not just determine the run-time type when you
|
|
|
|
|
indirect, and avoid the special case? The contents don't matter
|
|
|
|
|
until you indirect anyway.)
|
|
|
|
|
|
|
|
|
|
If we're not doing anything fancy, `enclosing_type' is equal to
|
|
|
|
|
`type', and `embedded_offset' is zero, so everything works
|
|
|
|
|
normally. */

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.

Notice that before value_optimized_out was made to auto-fetch lazy
values, VAL would end up still lazy if it was lazy on entry. It's not
really a problem here if VAL is lazy, and VAL->optimized_out is 0,
because RESULT is also left lazy. IOW, this just wants to copy the
VAL->optimized_out flag to RESULT->optimized_out, nothing else.
As a side-effect of the change in value_optimized_out, the following
testcase now regresses. Consider:
type Small is range -64 .. 63;
for Small'Size use 7;
type Arr is array (1..10) of Small;
pragma Pack (Arr);
type Arr_Ptr is access Arr;
An_Arr_Ptr : Arr_Ptr := new Arr'(10, 20, 30, 40, 50, 60, 62, 63,
-23, 42);
Trying to print one element of An_Arr_Ptr yields:
(gdb) p an_arr_ptr(3)
Cannot access memory at address 0x0
The patch adds the value_optimized_out_const function for that,
allowing us to avoid trying to fetch a value at a dummy address.
(I found this out by grepping for set_value_optimized_out and trying
to convert the uses I found to instead allocate the value with
allocate_optimized_out_value.)

|| TYPE_LENGTH (type) > TYPE_LENGTH (value_type (val)))
result = allocate_value_lazy (type);
else
{
result = allocate_value (type);
memcpy (value_contents_raw (result), value_contents (val),
TYPE_LENGTH (type));
}
set_value_component_location (result, val);
set_value_bitsize (result, value_bitsize (val));
set_value_bitpos (result, value_bitpos (val));
set_value_address (result, value_address (val));
set_value_optimized_out (result, value_optimized_out (val));
Notice that before value_optimized_out was made to auto-fetch lazy
values, VAL would end up still lazy if it was lazy on entry. It's not
really a problem here if VAL is lazy, and VAL->optimized_out is 0,
because RESULT is also left lazy. IOW, this just wants to copy the
VAL->optimized_out flag to RESULT->optimized_out, nothing else.
As a side-effect of the change in value_optimized_out, the following
testcase now regresses. Consider:
type Small is range -64 .. 63;
for Small'Size use 7;
type Arr is array (1..10) of Small;
pragma Pack (Arr);
type Arr_Ptr is access Arr;
An_Arr_Ptr : Arr_Ptr := new Arr'(10, 20, 30, 40, 50, 60, 62, 63,
-23, 42);
Trying to print one element of An_Arr_Ptr yields:
(gdb) p an_arr_ptr(3)
Cannot access memory at address 0x0
The patch adds the value_optimized_out_const function for that,
allowing us to avoid trying to fetch a value at a dummy address.
(I found this out by grepping for set_value_optimized_out and trying
to convert the uses I found to instead allocate the value with
allocate_optimized_out_value.)
Tested on x86_64 Fedora 17.

Add options to skip unavailable locals
This is the patch to add new option '--skip-unavailable' to MI
commands '-stack-list-{locals, arguments, variables}'. This patch
extends list_args_or_locals to add a new parameter 'skip_unavailable',
and don't list locals or arguments if values are unavailable and
'skip_unavailable' is true.
This is inspecting a trace frame (tfind mode), where only a few
locals have been collected.
-stack-list-locals, no switch vs new switch:
-stack-list-locals --simple-values
^done,locals=[{name="array",type="unsigned char [2]"},{name="i",type="int",value="<unavailable>"}]
-stack-list-locals --skip-unavailable --simple-values
^done,locals=[{name="array",type="unsigned char [2]"}]
-stack-list-arguments, no switch vs new switch:
-stack-list-arguments --simple-values
^done,stack-args=[frame={level="0",args=[{name="j",type="int",value="4"},{name="s",type="char *",value="<unavailable>"}]},frame={level="1",args=[]}]
-stack-list-arguments --skip-unavailable --simple-values
^done,stack-args=[frame={level="0",args=[{name="j",type="int",value="4"}]},frame={level="1",args=[]}]
-stack-list-variables, no switch vs new switch:
-stack-list-variables --simple-values
^done,variables=[{name="j",arg="1",type="int",value="4"},{name="s",arg="1",type="char *",value="<unavailable>"},{name="array",type="unsigned char [2]"},{name="i",type="int",value="<unavailable>"}]
-stack-list-variables --skip-unavailable --simple-values
^done,variables=[{name="j",arg="1",type="int",value="4"},{name="array",type="unsigned char [2]"}]
tests are added to test these new options.

Note that "contents" refers to the whole value's contents

example, to compare a complete object value with itself, including

its enclosing type chunk, you'd do:

|
Returns true iff the set of available contents match. Unavailable
|
|
|
|
|
contents compare equal with unavailable contents, and different
|
|
|
|
|
with any available byte. For example, if 'x's represent an
|
|
|
|
|
unavailable byte, and 'V' and 'Z' represent different available
|
|
|
|
|
bytes, in a value with length 16:

[PR tui/14880] Fetch values before comparing their contents.

/* This routine is used by printing routines, where we should

The fix is to fetch the value before comparing the contents. The
comment additions to value.h explain why it can't be
value_available_contents_eq itself that fetches the contents.
Tested on x86_64 Fedora 17.

language-specific read_var_value for Ada renamings
The purpose of this patch is to better support renamings in the
"info locals" command. Consider ...
procedure Foo is
GV : Integer renames Pck.Global_Variable;
begin
Increment (GV); -- STOP
end Foo;
... Pck.Global_Variable is just an integer. After having stopped at
the "STOP" line, "info locals" yields:
(gdb) info locals
gv = <error reading variable gv (Cannot access memory at address 0xffffffffffffffff)>
In reality, two things are happening:
(1) Variable "GV" does not exist, which is normal, since there is
"GV" the renaming of another variable;
(2) But to allow the user access to that renaming the same way
the code has, the compiler produces an artificial variable
whose name encodes the renaming:
gv___XR_pck__global_variable___XE
For practical reasons, the artificial variable itself is given
irrelevant types and addresses.
But the "info locals" command does not act as if it was a short-cut
of "foreach VAR in locals, print VAR". Instead it gets the value of
each VAR directly, which does not work in this case, since the variable
is artificial and needs to be decoded first.
This patch makes the "read_var_value" routine language-specific.
The old implementation of "read_var_value" gets renamed to
"default_read_var_value" and all languages now use it (unchanged
behavior), except for Ada. In Ada, the new function ada_read_var_value
checks if we have a renaming, and if so, evaluates its value, or else
defers to default_read_var_value.
gdb/ChangeLog:
* language.h (struct language_defn): New "method" la_read_var_value.
* findvar.c: #include "language.h".
(default_read_var_value): Renames read_var_value. Rewrite
function description.
(read_var_value): New function.
* value.h (default_read_var_value): Add prototype.
* ada-lang.c (ada_read_renaming_var_value, ada_read_var_value):
New functions.
(ada_language_defn): Add entry for la_read_var_value.
* c-lang.c, d-lang.c, f-lang.c, jv-lang.c, language.c,
* m2-lang.c, objc-lang.c, opencl-lang.c, p-lang.c: Update
language_defn structures to add entry for new la_read_var_value
field.
