c-common.c (c_expand_expr): Remove code to return a value different from that returned by expand_expr.
* c-common.c (c_expand_expr): Remove code to return a value
different from that returned by expand_expr.
* expr.c (store_expr): Use the validity of a target MEM, rather
than checking DECL_RTL (exp), to figure out if a copy is
required.
