# This file just makes sure that the .fini and .init sections do in
# fact return.  Users may put any desired instructions in those sections.
# This file is the last thing linked into any executable.

	# Note - this macro is complemented by the FUNC_START macro
	# in crti.asm.  If you change this macro you must also change
	# that macro match.
	#
	# Note - we do not try any fancy optimizations of the return
	# sequences here, it is just not worth it.  Instead keep things
	# simple.  Restore all the save resgisters, including the link
	# register and then perform the correct function return instruction.
	# We also save/restore r3 to ensure stack alignment.
