-/* Fill a block of memory with zeros.  Optimized for the Alpha architecture:
-
-   - memory accessed as aligned quadwords only
-   - destination memory not read unless needed for good cache behaviour
-   - basic blocks arranged to optimize branch prediction for full-quadword
-     aligned memory blocks.
-   - partial head and tail quadwords constructed with byte-mask instructions
-
-   This is generally scheduled for the EV5 (got to look out for my own
-   interests :-), but with EV4 needs in mind.  There *should* be no more
-   stalls for the EV4 than there are for the EV5.
