        * config/ia64/ia64-protos.h (ia64_function_arg): Delete.
        (ia64_function_arg_advance): Delete.
        * config/ia64/ia64.h (FUNCTION_ARG, FUNCTION_INCOMING_ARG): Delete.
        (FUNCTION_ARG_ADVANCE): Delete.
        * config/ia64/ia64.c (ia64_function_arg): Rename to...
        (ia64_function_arg_1): ...this.  Make static.  Take const_tree and
        bool arguments.
        (ia64_function_arg, ia64_function_incoming_arg): New functions.
        (ia64_function_arg_advance): Make static.  Take a const_tree and
        a bool.
        (TARGET_FUNCTION_ARG, TARGET_FUNCTION_INCOMING_ARG): Define.
