	PR target/12476
	* config/arm/arm.c (arm_output_mi_thunk):  In Thumb mode, use
	'bx' instead of 'b' to avoid branch range restrictions.  Output
	the thunk immediately before the thunked-to function.
	* config/arm/arm.h (ARM_DECLARE_FUNCTION_NAME):  Do not emit
	.thumb_func if a thunk is being generated.  Emit .code 16 along
	with .thumb_func if a thunk is not being generated.
	
	2003-11-05  Mark Mitchell  <mark@codesourcery.com>
	
	* calls.c (initialize_argument_information): Add CALL_FROM_THUNK_P
	parameter.  Use it instead of current_function_is_thunk.
	* function.h (struct function): Update documentation for is_thunk.
	* tree.h (CALL_FROM_THUNK_P): New macro.
	* config/alpha/alpha.c (alpha_sa_mask): Do not check
	no_new_pseudos when testing current_function_is_thunk.
	* config/rs6000/rs6000.c (rs6000_ra_ever_killed): Likeiwse.

	* decl.c (cxx_push_function_context): Do not set
	current_function_is_thunk.
	* method.c (use_thunk): Set CALL_FROM_THUNK on the call to the
	actual function.
