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".
