+   conflict, the same hard register R0 is used for the both reloads
+   but in this case the second reload needs an intermediate register
+   (which is the reload register).  As the result we have the
+   following code
+
+   	mov	#4,r0   -- first reload
+	mov	r14,r0  -- second reload
+	add	r0,r0   -- second reload
+
+   The right code should be
+
+   	mov	#4,r0   -- first reload
+	mov	r14,r1  -- second reload
+	add	r0,r1   -- second reload
