+
+       * arm.c (arm_arch4t): New variable.
+       (arm_override_options): Initialize it.  If compiling for armv5 or
+       higher clear TARGET_INTERWORK.
+       (output_call): Abort if called for armv5.  Use BX if it's available.
+       (output_call_mem): Use BLX if available and ensure that all armv5
+       code is interworking safe.
+       (output_return_instruction): Always use BX in preference to MOV if
+       it's available.
+       (arm_output_epilogue): Likewise.
+       (arm_final_prescan_insn): Never conditionally call a subroutine
+       on armv5.
+       * arm.h (arm_arch4t): Declare.
+       * arm.md (call_reg_armv5, call_value_reg_armv5): New.
+       (call_reg_arm, call_value_reg_arm): Renamed from call_reg and 
+       call_value_reg respectively.
+       (call_reg_thumb_v5, call_value_reg_thumb_v5): New.
+       (call_reg_thumb, call_value_reg_thumb): Renamed from call_indirect
+       and call_value_indirect respectively.
