   4  * This file is -include'd when compiling 16-bit C code.
   5  * Note: this asm() needs to be emitted before gcc emits any code.
   6  * Depending on gcc version, this requires -fno-unit-at-a-time or
   7  * -fno-toplevel-reorder.
   8  *
   9  * Hopefully gcc will eventually have a real -m16 option so we can
  10  * drop this hack long term.
