> Perhaps you could look into that? The fundamental issue appears to be that the chip won't schedule the instruction that updates "n" along with any instruction that uses "n" as an input (which are all the memory operations, which must issue every cycle for this perfect scheduling to work). Even if we put the 'n' update later in the instruction group than the referencing instruction. I actually don't have a pre-UltraSPARC-III system powered on and at hand at the moment to toy with that scheduling issue, I only tested on an UltraSPARC-IIIi. _______________________________________________ gmp-devel mailing list gmp-devel@gmplib.org http://gmplib.org/mailman/listinfo/gmp-devel
