-; This runs at 9 cycles/limb on a PA7000.  With the used instructions, it can
-; not become faster due to data cache contention after a store.  On the
-; PA7100 it runs at 7 cycles/limb, and that can not be improved either, since
-; only the xmpyu does not need the integer pipeline, so the only dual-issue
-; we will get are addc+xmpyu.  Unrolling would not help either CPU.
-
-; We could use fldds to read two limbs at a time from the S1 array, and that
-; could bring down the times to 8.5 and 6.5 cycles/limb for the PA7000 and
-; PA7100, respectively.  We don't do that since it does not seem worth the
-; (alignment) troubles...
-
-; At least the PA7100 is rumored to be able to deal with cache-misses
-; without stalling instruction issue.  If this is true, and the cache is
-; actually also lockup-free, we should use a deeper software pipeline, and
-; load from S1 very early!  (The loads and stores to -12(sp) will surely be
-; in the cache.)
