+;; PPC740/PPC750/PPC7400  32-bit 2xIU, LSU, SRU, FPU, BPU
+;; IU1 can perform all integer operations
+;; IU2 can perform all integer operations except imul and idiv
+;; LSU 2 stage pipelined
+;; FPU 3 stage pipelined
+;; Max issue 3 insns/clock cycle (includes 1 branch)
+;; In-order execution
+
+
+;; The PPC750 user's manual recommends that to reduce branch mispredictions,
+;; the insn that sets CR bits should be separated from the branch insn
+;; that evaluates them.  There is no advantage have more than 10 cycles
+;; of separation.
+;; This could be artificially achieved by exagerating the latency of
+;; compare insns but at the expense of a poorer schedule.
+
+;; Branches go straight to the BPU.  All other insns are handled
+;; by a dispatch unit which can issue a max of 2 insns per cycle.
