/* PR debug/5770
   This testcase failed at -O -g because the following constants
   were optimized away since they were never referenced, but
   since they are variables with initializers, rtl_for_decl_location
   run expand_expr on their initializers and returned it.
   This lead to references to constants which were deferred and thus
   never emitted.  */
