Subject: [Patch ARM] Call final_start_function and final_end_function in arm_output_mi_thunk.
List-Archive: <http://gcc.gnu.org/ml/gcc-patches/>

Hi,

	Ports should call final_start_function and final_end_function to get
proper debug info for the thunk as per
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55257#c3 . Fixes failing
tests in g++.dg for arm-*-*eabi.

Tested on arm-linux-gnueabi cross for armv7-a, arm/thumb2 and armv5t on
qemu. Applied.

	* config/arm/arm.c (arm_output_mi_thunk): Call final_start_function and
	final_end_function.
