2/02/00: Initial version // 4/13/00: Improved speed // 4/19/00: Removed the qualifying predicate from the fmerge.s that // takes the absolute value. // 6/16/00: Reassigned FP registers to eliminate stalls on loads // 8/30/00: Saved 5 cycles in main path by rearranging large argument logic // and delaying use of result of fcmp in load by 1 group // // API
