+       * config/arm/arm.c (arm_init_cumulative_args); New function:
+       Initlaise the CUMULATIE_ARGS strcuture for a function
+       defintion. 
+       (arm_function_arg): New function: Determine where to place a
+       function's argument.  Also handles deciding the function's
+       call cookie.
+       (current_file_function_operand): New function: Return true if
+       the symbol is a function which has already been compiled.
+       (arm_is_long_call_p): New function: Return true if the
+       indicated function should be called via a long call.
+       (arm_valid_type_attribute_p): New function: Return true if the
+       attribute is a valid, arm specific, attribute.
+       (arm_comp_type_attribute): New function: Return true if the
+       two types have compatable, arm specific, attributes.
+
+       * config/arm/arm.h (CUMULATIVE_ARGS): Redefine to be a
+        structure.
+       (FUNCTION_ARG): Redefine to call arm_function_arg.
+       (FUNCTION_ARG_PARTIAL_NREGS): Redefine to use correct
+        structure field.
+       (INIT_CUMULATIVE_ARGS): Redefine to call
+        arm_init_cumulative_args.
+       (FUNCTION_ARG_ADVANCE): Redefine to use correct structure
+        field. 
+       (SETUP_INCOMING_VARARGS): Redefine to use correct structure 
+        field. 
+       (ARM_MARK_NEARBY_FUNCTION): New macro: Mark already compiled
+        functions.
+       (ENCODE_SECTION): Add call to ARM_MARK_NEARBY_FUNCTION.
+       (VALID_MACHINE_TYPE_ATTRIBUTE): Define.
+       (COMP_TYPE_ATTRIBUTES): Define.
+
+       * config/arm/arm.md (call): Call arm_is_long_call_p to decide
+        if a long call is needed.
+       (call_value): Call arm_is_long_call_p to decide if a long call
+        is needed.
+       (call_symbol): Call arm_is_long_call_p to decide if a long call
+        is needed.
+
+       * config/arm/arm-protos.h: Add prototype for arm_is_long_call_p.
