Adding a new Struct (RECORD_TYPE)

[Petros Panayi <petrosp at cs dot ucy dot ac dot cy>]

Hi,
I try to create and populate a new struct into my the generated code. 
Something like:
struct ddm_temaplate{
   int loop_interations;
   int ddm_thread_num;
};

What I have up to now is the following:

static tree build_ddm_template_struct() {
   tree type = lang_hooks.types.make_type(RECORD_TYPE);
   tree id, field, fields;
   id = get_identifier("loop_interations");
   fields = build_decl (FIELD_DECL,id, integer_type_node);
   id = get_identifier("ddm_thread_num");
   field = build_decl (FIELD_DECL, id, integer_type_node);
   TREE_CHAIN (field) = fields;
   fields = field;
   finish_builtin_struct(type, "__ddm_template", fields, NULL_TREE);
   return type;

}

/* After this call I get somthing like struct __ddm_template 
.ddm_template_instance.38; ...*/
static tree build_struct_instance(tree type) {
   tree arg_struct_instance, var;
   arg_struct_instance = create_tmp_var(type, ".ddm_template_instance");
   return arg_struct_instance;
}

and I use them as

   type = build_ddm_template_struct();
   struct_instance = build_struct_instance(type);
  
   fields = TYPE_FIELDS (type);
   t = build3(COMPONENT_REF, type, struct_instance, fields, NULL_TREE);
   tree astmt = build_gimple_modify_stmt(t,build_int_cstu 
(lang_hooks.types.type_for_size (32, true),99));
   print_generic_stmt(stderr, astmt,0); /* Here i get something like 
.ddm_template_instance.38.loop_interations = 99; */
   bsi_insert_after(&si, astmt, BSI_NEW_STMT);

This code will create an error when verify_loop_closed_ssa() is called.
I believe the problem is that loop_interations field does not get an SSA 
name.

Can anyone help me fixing this problem.
Thanks in advance
Petros
