# 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.
