-/* Fills a memory region with specified byte value
- * This version is optimized for speed
- *
- * arguments:
- *  r4 - start address
- *  r5 - data
- *  r6 - length
- *
- * return value:
- *  r0 - start address (like ANSI version)
- *
- * register usage:
- *  r0 - temporary
- *  r1 - start address +11 for main loop
- *  r4 - start address
- *  r5 - data (spread to all 4 bytes when using long stores)
- *  r6 - current address (runs down from end to start)
- *
- * The instruction order below is devised in a way to utilize the pipelining
- * of the SH1 to the max. The routine fills memory from end to start in
- * order to utilize the auto-decrementing store instructions.
