(Ada) Fix -var-list-children MI command for union type
Using this Ada code:
type Union_Type (A : Boolean := False) is record
case A is
when True => B : Integer;
when False => C : Float;
end case;
end record;
pragma Unchecked_Union (Union_Type);
Ut : Union_Type := (A => True, B => 3);
In GDB/MI mode, once creating a varobj from variable "Ut" as follow:
(gdb) -var-create var1 * ut
^done,name="var1",numchild="2",value="{...}",type="foo.union_type",thread-id="1",has_more="0"
Printing the list of its children displays:
(gdb) -var-list-children 1 var1
^error,msg="Duplicate variable object name"
Whereas it should be
(gdb) -var-list-children 1 var1
^done,numchild="2",children=[child={name="var1.b",exp="b",numchild="0",value="3",type="integer",thread-id="1"},child={name="var1.c",exp="c",numchild="0",value="4.20389539e-45",type="float",thread-id="1"}],has_more="0"
The problem occurs because ada_varobj_describe_struct_child wasn't
handling unions. This patch fixes this.
gdb/ChangeLog:
* ada-varobj.c (ada_varobj_describe_struct_child)
(ada_varobj_describe_child): Handle union case like struct one.
testsuite/ChangeLog
* gdb.ada/mi_var_union.exp: New testcase.
* gdb.ada/mi_var_union/bar.adb: New file.
* gdb.ada/mi_var_union/pck.adb: New file.
* gdb.ada/mi_var_union/pck.asd: New file.
Tested on x86_64-linux.
