/* AOF Assembler syntax is a nightmare when it comes to areas, since once
we change from one area to another, we can't go back again. Instead,
we must create a new area with the same attributes and add the new output
to that. Unfortunately, there is nothing we can do here to guarantee that
two areas with the same attributes will be linked adjacently in the
resulting executable, so we have to be careful not to do pc-relative
addressing across such boundaries. This isn't a major problem for thumb,
since the range of such addressing modes is so limited that it would
rarely be useful anyway. */
