- * RTEMS
- *
- * This routine jumps to the directive indicated in r11.
- * This routine is used when RTEMS is linked by itself and placed
- * in ROM. This routine is the first address in the ROM space for
- * RTEMS. The user "calls" this address with the directive arguments
- * in the normal place.
- * This routine then jumps indirectly to the correct directive
- * preserving the arguments. The directive should not realize
- * it has been "wrapped" in this way. The table "_Entry_points"
- * is used to look up the directive.
