35 
;;   fourth stage for simple operations.
36

37 
;; - A 5-stage DS pipeline (4 execute + writeback) for divide/sqrt insns.
38 
;;   These insns also uses first execute stage of FMAC pipeline.

40 
;; - A 4-stage LS pipeline (execute + 2 memory + writeback) with forward from

47 
;; We do not model fmstat properly.  This could be done by modeling pipelines
48 
;; properly and defining an absence set between a dummy fmstat unit and all
49
