-/* These labels & instructions are used by the Arm/Thumb interworking code,
-   when the target address is in an unknown instruction set.  The address 
-   of function to be called is loaded into a register and then one of these
-   labels is called via a BL instruction.  This puts the return address 
-   into the link register with the bottom bit set, and the code here 
-   switches to the correct mode before executing the function.  Unfortunately
-   the target code cannot be relied upon to return via a BX instruction, so
-   instead we have to store the resturn address on the stack and allow the
-   called function to return here instead.  Upon return we recover the real
-   return address and use a BX to get back to Thumb mode.  */
