        * lra-constraints.c (process_address_1): Check is_address flag
        for address constraints.
        (process_alt_operands): Likewise.
        * lra.c (lra_set_insn_recog_data): Pass asm operand locs to
        preprocess_constraints.
        * recog.h (preprocess_constraints): Add oploc parameter.
        Adjust callers.
