-;! INPUT PARAMETERS
-;! res_ptr	r26
-;! s1_ptr	r25
-;! size		r24
-;! s2_limb	r23
-
-;! This runs at 11 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 10 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 could gain a cycle/limb
-;! on the PA7100.
-
-;! There are some ideas described in mul_1.s that applies to this code too.
