+;; DFA based pipeline description for the r3000
+;; This is a special pipeline - this is also the default schedule and
+;; so we need to schedule instructions that may not exist on the r2k/r3k.
+
+;; Generic processor description that assumes that the only latencies are for
+;; hazards or delay slots, otherwise everything is assumed to issue and execute
+;; in one cycle.
