;; AMD bdver3 and bdver4 Scheduling
;;
;; The bdver3 and bdver4 contains three pipelined FP units and two integer
;; units. ;; Fetching and decoding logic is different from previous fam15 
;; processors. Fetching is done every two cycles rather than every cycle 
;; and two decode units are available. The decode units therefore decode
;; four instructions in two cycles.
;;
;; The load/store queue unit is not attached to the schedulers but
;; communicates with all the execution units separately instead.
;;
;; bdver3 and bdver4 belong to fam15 processors. We use the same insn 
;; attribute that was used for bdver1 decoding scheme.
