        * alpha.c (alpha_cpu_name, alpha_cpu_string, alpha_tp_string,
        alpha_fprm_string, alpha_fptm_string, alpha_mlat_string,
        current_function_file): Add the `const' keyword.
        (normal_memory_operand): Mark parameter `mode' with
        ATTRIBUTE_UNUSED.
        (alpha_expand_unaligned_load): Add a default case to a switch.
        * alpha.h (alpha_cpu_string, alpha_fprm_string, alpha_fptm_string,
        alpha_tp_string, alpha_mlat_string): Add the `const' keyword.
        (normal_memory_operand): Add prototype.
        * alpha.md: Cast an expression to `unsigned HOST_WIDE_INT' when
        comparing against one.
