C 8000,8200:		6.5
C 8500,8600,8700:	5.625

C  The feed-in and wind-down code has not yet been scheduled.  Many cycles
C  could be saved there per call.

C  DESCRIPTION:
C  The main loop "BIG" is 4-way unrolled, mainly to allow
C  effective use of ADD,DC.  Delays in moving data via the cache from the FP
C  registers to the IU registers, have demanded a deep software pipeline, and
C  a lot of stack slots for partial products in flight.
C
C  CODE STRUCTURE:
C  save-some-registers
C  do 0, 1, 2, or 3 limbs
C  if done, restore-some-regs and return
C  save-many-regs
C  do 4, 8, ... limb
C  restore-all-regs

C  STACK LAYOUT:
C  HP-PA stack grows upwards.  We could allocate 8 fewer slots by using the
C  slots marked FREE, as well as some slots in the caller's "frame marker".
