+ #  s2_limb	$19
+ #
+ #  This code runs at 42 cycles/limb on EV4, 18 cycles/limb on EV5, and
+ #  exactly 3.625 cycles/limb on EV6...
+ #
+ # This code was written in close cooperation with ev6 pipeline expert
+ # Steve Root (root@toober.hlo.dec.com).  Any errors are tege's fault, though.
+ #
+ #   Register usages for unrolled loop:
+ #	  0-3     mul's
+ #	  4-7     acc's
+ #	  8-15    mul results
+ #	  20,21   carry's
+ #	  22,23   save for stores
+ #
+ #   Sustains 8 mul-adds in 29 cycles in the unrolled inner loop.
+ #
+ #   The stores can issue a cycle late so we have paired no-op's to 'catch'
+ #   them, so that further disturbance to the schedule is damped.
+ #
+ #   We couldn't pair the loads, because the entangled schedule of the
+ #   carry's has to happen on one side {0} of the machine. Note, the total
+ #   use of U0, and the total use of L0 (after attending to the stores).
+ #   which is part of the reason why....
+ #
+ #   This is a great schedule for the d_cache, a poor schedule for the
+ #   b_cache. The lockup on U0 means that any stall can't be recovered
+ #   from. Consider a ldq in L1.  say that load gets stalled because it
+ #   collides with a fill from the b_Cache. On the next cycle, this load
+ #   gets priority. If first looks at L0, and goes there. The instruction
+ #   we intended for L0 gets to look at L1, which is NOT where we want
+ #   it. It either stalls 1, because it can't go in L0, or goes there, and
+ #   causes a further instruction to stall.
+ #
+ #   So for b_cache, we're likely going to want to put one or more cycles
+ #   back into the code! And, of course, put in prefetches. For the
+ #   accumulator, lds, intent to modify.  For the multiplier, you might
+ #   want ldq, evict next, if you're not wanting to use it again soon. Use
+ #   256 ahead of present pointer value. At a place where we have an mt
+ #   followed by a bookkeeping, put the bookkeeping in upper, and the
+ #   prefetch into lower.
+ #
+ #   Note, the usage of physical registers per cycle is smoothed off, as
+ #   much as possible.
+ #
+ #   Note, the ldq's and stq's are at the end of the quadpacks.  note, we'd
+ #   like not to have a ldq or stq to preceded a conditional branch in a
+ #   quadpack. The conditional branch moves the retire pointer one cycle
+ #   later.
+ #
+ #   Optimization notes:
+ #   Callee-saves regs: $9 $10 $11 $12 $13 $14 $15 $26 ?$27?
+ #   Reserved regs:	 $29 $30 $31
+ #   Free caller-saves regs in unrolled code: $24 $25 $28
+ #   We should swap some of the callee-saves regs for some of the free
+ #   caller-saves regs, saving some overhead cycles.
+ #   Most importantly, we should write fast code for the 0-7 case.
+ #   The code we use there are for the 21164, and runs at 7 cycles/limb
+ #   on the 21264.  Should not be hard, if we write specialized code for
+ #   1-7 limbs (the one for 0 limbs should be straightforward).  We then just
+ #   need a jump table indexed by the low 3 bits of the count argument.
