-
-; Common overhead is about 11 cycles/invocation.
-
-; The speed for S2_LIMB >= 0x10000 is approximately 21 cycles/limb.  (The

-
-; The speed for S2_LIMB < 0x10000 is approximately 16 cycles/limb.  (The
-; pipeline stalls 2 cycles due to WB contention and 1 cycle due to latency.)
-
-; To enhance speed:
-; 1. Unroll main loop 4-8 times.
-; 2. Schedule code to avoid WB contention.  It might be tempting to move the
-;    ld instruction in the loops down to save 2 cycles (less WB contention),
-;    but that looses because the ultimate value will be read from outside
-;    the allocated space.  But if we handle the ultimate multiplication in
-;    the tail, we can do this.
-; 3. Make the multiplication with less instructions.  I think the code for
-;    (S2_LIMB >= 0x10000) is not minimal.
-; With these techniques the (S2_LIMB >= 0x10000) case would run in 17 or
