53ba833325 [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).

        * value.h (set_value_parent): Add declaration.
        * value.c (set_value_parent): New function.

1b61134393 [Ada] avoid error message pollution with uninitialized tagged variable
Consider the following function...

  3 procedure Foo is
  4    I : Integer := Ident (10);
  5    Obj : Base;
  6 begin
  7    Obj.X := I;
  8    Do_Nothing (Obj.X'Address);
  9 end Foo;

... where type "Base" is defined as a plain tagged record. If the user
stops execution before "Obj" gets initialized (for example, by inserting
a breakpoint "on" the function - or in other words, by inserting a
breakpoint using the function name as the location), one might get
the following of output if you try printing the value of obj:

    (gdb) p obj
    object size is larger than varsize-limit
    object size is larger than varsize-limit
    object size is larger than varsize-limit
    $1 = object size is larger than varsize-limit
    (x => 4204154)

Same thing with "info locals":

   (gdb) info locals
    i = 0
    obj = object size is larger than varsize-limit
    (x => 4204154)

We have also seen different error messages such as "Cannot read
memory at 0x...".

The error happens because we are trying to read the dispatch table
of a tagged type variable before it gets initialized.  So the errors
might legitimately occur, and are supposed to be be contained.
However, the way things are written in ada-lang.c:ada_tag_name,
although the exception is in fact contained, the error message still
gets to be printed out.

This patch prevents this from happening by eliminating the use of
catch_errors, and using a TRY_CATCH block instead.  Doing this removed
the need to use functions specifically fitted for catch_errors, and
thus some other simplifications could me made.  In the end, the code
got reorganized a bit to better show the logic behind it, as well as
the common patterns.

gdb/ChangeLog:

99b1c762c9 [Ada] print packed arrays indexed by enumerated type
Consider the following declarations (a packed array indexed by an
enumerated type):

    type Color is (Black, Red, Green, Blue, White);
    type Full_Table is array (Color) of Boolean;
    pragma Pack (Full_Table);
    Full : Full_Table := (False, True, False, True, False);

GDB is unable to print the index values correctly. It prints the
enumeration's underlying value instead of the enumeration name:

    (gdb) p full
    $1 = (0 => false, true, false, true, false)
    (gdb) p full'first
    $2 = 0

And yet, it is capable of printing the correct type description:

    (gdb) ptype full
    type = array (black .. white) of boolean <packed: 1-bit elements>

To get to the real index type, one has to follow the parallel XA type.
We already do this for normal arrays. We can do it for this packed
array as well.

gdb/ChangeLog:

        * ada-lang.c (constrained_packed_array_type): If there is a
        parallel XA type, use it to determine the array index type.

gdb/testsuite/ChangeLog:

        * gdb.ada/arrayidx.exp: Adjust expected output for p_one_two_three.
        * gdb.ada/enum_idx_packed: New testcase.

2d4a02ee95 [Ada] Handle reference to array descriptors
This patch is to help handle aliased array variables, such as:

   type Bounded is array (Integer range <>) of Integer;
   function New_Bounded (Low, High : Integer) return Bounded;
   BT : aliased Bounded := New_Bounded (Low => 1, High => 3);

In that case, the compiler describes variable "BT" as a reference
to a thin pointer, and GDB is unable to print its value:

    (gdb) p bt
    $1 =

The problems starts when ada_value_print deconstructs the struct
value into contents and address in order to call val_print. It
turns out in this case that "bt" is not an lval. In the debug
information, this variable's location is described as:

        .uleb128 0xd    # (DIE (0xe0) DW_TAG_variable)
        .ascii "bt\0"   # DW_AT_name
        [...]
        .byte   0x6     # DW_AT_location
        .byte   0x91    # DW_OP_fbreg
        .sleb128 -56
        .byte   0x6     # DW_OP_deref
        .byte   0x23    # DW_OP_plus_uconst
        .uleb128 0x8
        .byte   0x9f    # DW_OP_stack_value

So, when ada_value_print passes the bt's (value) address, it passes
in effect a meaningless address. The problem continues shortly after
when ada_val_print_1 re-creates the value from the contents and address.
The value has become an lval_memory, with a null address.

As a result, we trigger a memory error later on, while trying to
read the array bounds in order to transform our value into a simple
array.

To avoid the problem entirely, the fix is to coerce references before
transforming array descriptors into simple arrays.

gdb/ChangeLog:

        * ada-valprint.c (ada_val_print_1): If our value is a reference
        to an array descriptor, dereference it before converting it
        to a simple array.

2e6fda7d06 [Ada] whatis not printing array type name for value from history
Consider the following declaration:

   type Full_Table is array (Color) of Integer;
   Full : Full_Table := (144, 233, 377, 610, 987);

The debugger correctly prints the type name of variable "full":

        (gdb) whatis full
        type = pck.full_table

But is unable to do so when using the value history:

        (gdb) print full
        $1 = (144, 233, 377, 610, 987)
        (gdb) whatis $
 !!! -> type = array (black .. white) of integer

This is because the evaluation creates a "fixed" version of
the array type, and that "fixed" version is missing a type name.
As a result, whatis falls back to describing the type (a la ptype)
instead of printing the type name.

gdb/ChangeLog:

        * ada-lang.c (to_fixed_array_type): Set result's type name.
