*実装 [#fb1d686d]
 /* After emitting to a sequence, restore previous saved state.
 
    To get the contents of the sequence just made, you must call
    `get_insns' *before* calling here.
 
    If the compiler might have deferred popping arguments while
    generating this sequence, and this sequence will not be immediately
    inserted into the instruction stream, use do_pending_stack_adjust
    before calling get_insns.  That will ensure that the deferred
    pops are inserted into this sequence, and not into some random
    location in the instruction stream.  See INHIBIT_DEFER_POP for more
    information about deferred popping of arguments.  */
