;! 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.
