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.

We could allocate 8 fewer slots by using the C slots marked FREE, as well as some slots in the caller's "frame marker".
