Simon Marchi c1cc615262 Finish constification of varobj interface 
This completes the constification of the struct varobj pointers in the
lang_varobj_ops interface partially done in
b09e2c591f. As suggested by Pedro,
varobj_get_path_expr casts away the const to assign the "mutable" struct
member.

Simon Marchi b09e2c591f Constify some parameters in the varobj code 
To make it clear that some functions should not modify the variable
object, this patch adds the const qualifier where it makes sense to some
struct varobj * parameters. Most getters should take a const pointer to
guarantee they don't modify the object.

Unfortunately, I couldn't add it to some callbacks (such as name_of_child).
In the C implementation, they call c_describe_child, which calls
varobj_get_path_expr. varobj_get_path_expr needs to modify the object in
order to cache the computed value. It therefore can't take a const
pointer, and it affects the whole call chain. I suppose that's where you
would use a "mutable" in C++.

I did that to make sure there was no other cases like the one fixed in
the previous patch. I don't think it can hurt.

Simon Marchi 2568868e69 Set varobj->path_expr in varobj_get_path_expr 
It seems like different languages are doing this differently (e.g.
C and Ada). For C, var->path_expr is set inside c_path_expr_of_child.
The next time the value is requested, is it therefore not recomputed.
Ada does not set this field, but just returns the value. Since the field
is never set, the value is recomputed every time it is requested.

This patch makes it so that path_expr_of_child's only job is to compute
the path expression, not save/cache the value. The field is set by the
varobj common code.

Andrew Burgess 9a9a760829 Improve MI -var-info-path-expression for nested struct/union case. 
https://sourceware.org/ml/gdb-patches/2014-05/msg00383.html

The MI command -var-info-path-expression currently does not handle
non-anonymous structs / unions nested within other structs / unions,
it will skip parts of the expression.  Consider this example:

  ## START EXAMPLE ##
  $ cat ex.c
  #include <string.h>

  int
  main ()
  {
    struct s1
    {
      int a;
    };

    struct ss
    {
      struct s1 x;
    };

    struct ss an_ss;
    memset (&an_ss, 0, sizeof (an_ss));
    return 0;
  }
  $ gcc -g -o ex.x ex.c
  $ gdb ex.x
  (gdb) break 18
  Breakpoint 1 at 0x80483ba: file ex.c, line 18.
  (gdb) run
  Starting program: /home/user/ex.x

  Breakpoint 1, main () at ex.c:18
  18	  return 0;
  (gdb) interpreter-exec mi "-var-create an_ss * an_ss"
  (gdb) interpreter-exec mi "-var-list-children an_ss"
  ^done,numchild="1",children=[child={name="an_ss.x",exp="x",numchild="1",type="struct s1",thread-id="1"}],has_more="0"
  (gdb) interpreter-exec mi "-var-list-children an_ss.x"
  ^done,numchild="1",children=[child={name="an_ss.x.a",exp="a",numchild="0",type="int",thread-id="1"}],has_more="0"
  (gdb) interpreter-exec mi "-var-list-children an_ss.x.a"
  ^done,numchild="0",has_more="0"
  (gdb) interpreter-exec mi "-var-info-path-expression an_ss.x.a"
  ^done,path_expr="(an_ss).a"
  (gdb) print (an_ss).a
  There is no member named a.
  ## END EXAMPLE ##

Notice that the path expression returned is wrong, and as a result
the print command fails.

This patch adds a new method to the varobj_ops structure called
is_path_expr_parent, to allow language specific control over finding
the parent varobj, the current logic becomes the C/C++ version and is
extended to handle the nested cases.  No other language currently uses
this code, so all other languages just get a default method.

With this patch, the above example now finishes like this:

  ## START EXAMPLE ##
  $ gdb ex.x
  (gdb) break 18
  Breakpoint 1 at 0x80483ba: file ex.c, line 18.
  (gdb) run
  Starting program: /home/user/ex.x

  Breakpoint 1, main () at ex.c:18
  18	  return 0;
  (gdb) interpreter-exec mi "-var-list-children an_ss"
  ^done,numchild="1",children=[child={name="an_ss.x",exp="x",numchild="1",type="struct s1",thread-id="1"}],has_more="0"
  (gdb) interpreter-exec mi "-var-list-children an_ss.x"
  ^done,numchild="1",children=[child={name="an_ss.x.a",exp="a",numchild="0",type="int",thread-id="1"}],has_more="0"
  (gdb) interpreter-exec mi "-var-list-children an_ss.x.a"
  ^done,numchild="0",has_more="0"
  (gdb) interpreter-exec mi "-var-info-path-expression an_ss.x.a"
  ^done,path_expr="((an_ss).x).a"
  (gdb) print ((an_ss).x).a
  $1 = 0
  ## END EXAMPLE ##

Notice that the path expression is now correct, and the print is a
success.

Tom Tromey 3977b71f1d constify struct block in some places 
This makes some spots in gdb, particularly general_symbol_info, use a
"const struct block", then fixes the fallout.

The justification is that, ordinarily, blocks ought to be readonly.
Note though that we can't add "const" in the blockvector due to block
relocation.  This can be done once blocks are made independent of the
program space.

Yao Qi cde5ef40f8 Rename varobj_pretty_printed_p to varobj_is_dynamic_p 
We think varobj with --available-children-only behaves like a dynamic
varobj, so dyanmic varobj is not pretty-printer specific.  We rename
varobj_pretty_printed_p to varobj_is_dynamic_p, so that we can handle
available-children-only checking in varobj_is_dynamic_p in the next
patch.

Yao Qi 827f100cee Iterate over 'struct varobj_item' instead of PyObject 
In previous patch, "saved_item" is still a PyOjbect and iteration is
still performed over PyObject.  This patch continues to decouple
iteration from python code, so it changes its type to "struct
varobj_item *", so that the iterator itself is independent of python.

Yao Qi e525021603 Generalize varobj iterator 
This patch generalizes varobj iterator, in a python-independent way.
Note varobj_item is still a typedef of PyObject, we can only focus on
API changes, and leave the data type changes to the next patch.  As a
result, we include "varobj-iter.h" after the typedef of PyObject in
varobj.c, but it is an intermediate state.  Finally, varobj-iter.h is
independent of PyObject.

This change is helpful to move some python-related code out of
varobj.c.

 V2:
  - Fix a missing cleanup.
  - Fix typos.
  - Use XNEW.
  - Check against NULL explicitly.
  - Update copyright year for new added files.

 V3:
  - Call PyGILState_Ensure before Py_XDECREF.
  - Use CPYCHECKER_STEALS_REFERENCE_TO_ARG.
  - Code indentation.

 V4:

Yao Qi 5a2e0d6e89 Use 'struct varobj_item' to represent name and value pair 
Hi,
name and value pair is widely used in varobj.c.  This patch is to add
a new struct varobj_item to represent them, so that the number of
function arguments can be reduced.  Finally, the iteration is done on
'struct varobj_item' instead of PyObject after this patch series.

Tom Tromey f989a1c8ec rename "set debugvarobj" to "set debug varobj" 
I think "set debugvarobj" has the wrong name.
It ought to be "set debug varobj", like gdb's other debug settings.

This patch makes the change.

I chose not to install deprecated aliases, since this is only a debug
setting; but if someone feels strongly about it I will add them.

Built and regtested on x86-64 Fedora 20.

Joel Brobecker 8776cfe971 [varobj] false type-changed status for reference to Ada array 
Given the following variable...

   BT : Bounded := New_Bounded (Low => 1, High => 3);

... where type Bounded is defined as a simple unconstrained array:

   type Bounded is array (Integer range <>) of Integer;

Creating a varobj for that variable, and immediately asking for
varobj updates, GDB says that our varobj changed types!

    (gdb)
    -var-create bt * bt
    ^done,name="bt",numchild="3",value="[3]",type="<ref> array (1 .. 3) of integer",has_more="0"
    (gdb)
    -var-update 1 *
    ^done,changelist=[{name="bt",value="[3]",in_scope="true",type_changed="true",new_type="<ref> array (1 .. 3) of integer",new_num_children="3",has_more="0"}]

The expected output for the -var-update command is, in this case:

    (gdb)
    -var-update 1 *
    ^done,changelist=[]

The problem occurs because the ada-varobj module does not handle
references, and while the references gets stripped when the varobj
gets created, it doesn't when computing varobj updates.

More specifically, when creating the varobj, varobj_create creates
a new value which is a reference to a TYPE_CODE_ARRAY. It then calls
install_new_value which calls coerce_ref with the following comment:

    /* We are not interested in the address of references, and given
       that in C++ a reference is not rebindable, it cannot
       meaningfully change.  So, get hold of the real value.  */
    if (value)
      value = coerce_ref (value);

This leaves the varobj's type component still a ref, while
the varobj's value is now our array, without the ref. This explains
why the "value" field in the varobj indicates an array with 3 elements
"[3]" while the "type" field shows a ref to an array. Generally
speaking, most users have said that showing the ref was a useful
piece of information, so this patch is not touching this part.

Next, when the user issues the -var-update request, varobj_update
calls value_of_root to compute the varobj's new value as well as
determine whether the value's type has changed or not. What happens
in a nutshell is that it calls value_of_root_1 (which re-evaluates
the expression and returns the corresponding new value), finds that
the new value is not NULL, and thus asks whether it has mutated:

    else if (varobj_value_has_mutated (var, value, value_type (value)))

This then indirectly delegates the determination to the language-specific
callback, which fails, because it does not handle references.

This patch fixes the issue by adjusting varobj_value_has_mutated to
expect references, and strip them when seen. This allows the various
language-specific implementations to remain unaware of references.

gdb/ChangeLog:

        * varobj.c (varobj_value_has_mutated): If NEW_VALUE is
        a reference, strip the reference layer before calling
        the lang_ops value_has_mutated callback.

        * gdb.ada/mi_dyn_arr: New testcase.

Yao Qi fa4d0c4081 Remove varobj_language_string, languages and varobj_languages 
This patch does some cleanups, removing some language-related stuff.
Note that mi_cmd_var_info_expression uses varobj_language_string,
which is redundant, because we can get language name from
lang->la_natural_name.

varobj_language_string doesn't have "Ada", which looks like a bug to
me.  With this patch applied, this problem doesn't exist, because the
language name is got from the same place (field la_natural_name).

Yao Qi a53b64eaa0 New field la_varobj_ops in struct language_defn 
This is a follow-up series to move language stuff out of varobj.c.

This patch adds a new field la_varobj_ops in struct language_defn so
that each language has varobj-related options.  Not every language
supports varobj, and the operations are identical to operations of c
languages.

'struct language_defn' is the ideal place to save all language-related
operations.  After this patch, some cleanups can be done in patch 2/2,
which removes language-related stuff completely from varobj.c.

Regression tested on x86_64-linux.

Yao Qi 5e5ac9a570 Fix FIXME: xstrdup should not be here 
Hi,

This FIXME goes into my eyes, when I am about to modify something here,

  /* Name is allocated by name_of_child.  */
  /* FIXME: xstrdup should not be here.  */

This FIXME was introduced in the python pretty-pretter patches.

  Python pretty-printing [6/6]
  https://sourceware.org/ml/gdb-patches/2009-05/msg00467.html

create_child_with_value is called in two paths,

 1. varobj_list_children -> create_child -> create_child_with_value,
 2. install_dynamic_child -> install_dynamic_child -> varobj_add_child
    -> create_child_with_value

In path #1, 'name' is allocated by name_of_child, as the original
comment said, we don't have to duplicate NAME in
create_child_with_value.  In path #2, 'name' is got from
PyArg_ParseTuple, and we have to duplicate NAME.

This patch removes the call to xstrdup in create_child_with_value
and call xstrudp in update_dynamic_varobj_children (path #2).

As with the previous patch, the encoding conversion code works with
gdb_byte arrays as the generic buffers that hold strings of any
encoding/width.  This patch adds casts where appropriate.
