Xavier Roirand 2963898f38 (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.		2018-09-10 11:30:50 -04:00
